This paper describes an experimental investigation of rotor–stator interaction in a centrifugal pump with several vaned diffusers. Steady and unsteady diffuser vane pressure measurements were made for a two–dimensional test impeller. Unsteady impeller blade pressure measurements were made for a second two–dimensional impeller with blade number and blade geometry identical to the two–dimensional impeller used for the diffuser vane pressure measurements. The experiments were conducted for different flow coefficients and different radial gaps between the impeller blade trailing edge and the diffuser vane leading edge (5% and 8% of the impeller discharge radius). The largest pressure fluctuations on the diffuser vanes and the impeller blades were found to be of the same order of magnitude as the total pressure rise across the pump. The largest pressure fluctuations on the diffuser vanes were observed to occur on the suction side of the vane near the vane leading edge, whereas on the impeller blades the largest fluctuations were observed to occur at the blade trailing edge. However, the dependence of the fluctuations on the flow coefficient was found to be different for the diffuser vanes and the impeller blades; on the vane suction side, the fluctuations were largest for the maximum flow coefficient and decreased with decreasing flow coefficient, whereas at the blade trailing edge, the fluctuations were smallest for the maximum flow coefficient and increased with decreasing flow coefficient. Increasing the number of the diffuser vanes resulted in a significant decrease of the impeller blade pressure fluctuations. The resulting lift on the diffuser vanes was computed from the vane pressure measurements; the magnitude of the fluctuating lift was found to be larger than the steady lift.

The branch of the Russian company Vozrozhdenie in Turkmenistan has completed excavation works at the site of construction of mudflow protection facilities in Ashgabat and started concreting.
The company is expected to build a system of canals and pipelines (including construction of mud reservoirs, pumping stations and filter structures) and reconstruct the existing canal.
In March last year, President of Turkmenistan Gurbanguly Berdimuhamedov signed a decree authorizing the Ashgabat city administration to make a contract with Vozrozhdenie for design and construction of a number of mudflow prevention facilities in the southern part of the Turkmen capital. The project developed by Vozrozhdenie jointly with the Russian design institute “Sevkavgiprovodkhoz” was recognized as optimal. The construction of facilities should be completed in September 2022.


Launched with much fanfare just two days ago, the Rs 11-crore ambitious amphibious bus project of the Punjab government at the Harike wetland near Amritsar has been halted due to low water level, a senior officer said on Wednesday. The Harike Cruise was launched by deputy chief minister Sukhbir Singh Badal on Monday.
“The activity will have to halt for 15-20 days as the water level in the reservoir is very low for running the operation of bus,” Punjab tourism director Navjot Pal Singh Randhawa said here. “At present, the water level in the reservoir has receded and is only 3.5 feet deep. The reason is that the main gates of Rajasthan feeder canal and Ferozepur feeder canal have been raised for repairs, whereby the water from the reservoir is flowing downstream.”
“The minimum water level required for the operations of the amphibious Bus is 6 feet. As per the officials of irrigation department, the repairs of these gates would be completed in the next 15-20 days,” he said.
The bus has a 4-km ride in water and on land.

cooling water pump / electric / centrifugal / single-stage
DESMI Pumping Technology A/S
for cooling water
single-stage, in-line, stainless steel, process, replacement
Max.: 4,400 m³/h (155,384.5336 ft³/h)
Min.: 300 m³/h (10,594.4 ft³/h)
These are single-stage, double-suction, vertical, in-line, DESMI DSL centrifugal pumps. The design of the pump is remarkable - the inlet is in line with the outlet, the flow is smooth, thanks to the excellent suction side. When an advanced double-suction impeller is added to the pump, the performance is multiplied and low NPSH values. The DSL pump is built in line with CAD and CAM and has been modified to absorb the new CNC processing technology. These advantages make the pump have well-defined performance and specific and uniform tolerances. The strong construction of the pump is due to the bearings and mechanical shaft seal. The radical split of the pump makes it easy to remove and replace the bearings and the mechanical shaft seal. As there is no need to remove the motor and piping, it saves considerable time for the service personnel.


在综采工作面供液系统中，由于管路系统的压力损失对工作面液压支架动作的稳定性和快速性影响较大，所以该压力损失不容忽视，要力求采用一种压力损失较小的供液方法。采用理论计算并基于 Simulation X 仿真软件对不同供液方式下管路系统的压力损失与现场采集的数据进行分析。结果表明：理论计算与 Simulation X 仿真结果和现场数据在供液管路压力损失方面的变化趋势保持一致，验证了梯形供液方式的压力损失较小，约为5.0 MPa,且第1台支架和最后1台支架之间的压力损失约为1.0 MPa，是最适合于当前综采工作面的一种供液方式。
In the liquid supply system of fully mechanized working face,because the pressure loss of pipeline system has a great influence on the stability and rapidity of the hydraulic support action,the pressure loss can not be ignored,it should strive to adopt a liquid supply method with less pressure loss.Theoretical calculation and Simulation X software were used to analyze the pressure loss of pipeline system under different liquid supply modes and the data collected on site.The results show that the theoretical calculation results are consistent with the Simulation X results and field data in the variation trend of pressure loss of liquid supply pipeline,the pressure loss of trapezoidal liquid supply mode is small is verified,its value is about 5.0 MPa,and the pressure loss between the first support and the last support is about 1.0 MPa.Trapezoidal liquid supply mode is the most suitable liquid supply mode for the current fully mechanized working face.

THE Lesotho Highlands Development Authority (LHDA) has awarded SCLC Polihali Diversion Tunnel Joint Venture a M517 million contract for the construction of the Polihali diversion tunnels under Phase II of the Lesotho Highlands Water Project (LHWP).
The LHDA this week told the Lesotho Times that the diversion tunnels are part of the advance infrastructure works which also include the construction of roads ahead of the construction of the Polihali Dam.
The LHDA further said that the awarding of the contract for the construction of the Polihali diversion tunnels “marks another significant step in the implementation of Phase II of the LHWP”.
The LHWP is a multi-phase, bi-national initiative established by a 1986 Treaty between Maseru and Pretoria. It involves the construction of dams and water-transfer tunnels in the two neighbouring nations and the generation of hydro-electric power in Lesotho.
South Africa seeks to augment its water-supply for both domestic and industrial use through the project while Lesotho expects to benefit from infrastructure such as roads as well as royalties and electricity from the initiative.
Phase I of the LHWP, consisting of the Katse and Mohale dams, the ‘Muela hydropower station and associated tunnels was completed in 2003 and inaugurated in 2004. Phase II of the LHWP is currently in progress. It consists of two separate but related components: water transfer and hydropower generation.
The bilateral project which is estimated to cost at least M23 billion, is expected to provide about 3000 jobs at the peak of its operations.
The water transfer component of Phase II comprises an approximately 165m high concrete faced rock fill Dam at Polihali downstream of the confluence of the Khubelu and Senqu (Orange) Rivers and an approximately 38km long concrete-lined gravity tunnel connecting the Polihali reservoir to the Katse reservoir.
Other Phase II activities include advance infrastructure (roads, accommodation, power lines and telecommunication) and the implementation of environmental and social mitigating measures.
The hydropower component of Phase II, which is currently under further feasibility studies, may include a pumped storage scheme, conventional hydropower such as the expansion of the ‘Muela infrastructure or new greenfield sites.
Its exact form will be determined on completion of the further feasibility studies. Phase II is expected to be substantially complete by the end of 2024.
The LHDA is the implementing and management authority of the LHWP on behalf of Lesotho, while in South Africa, the project is governed by the Trans-Caledon Tunnel Authority.
This week, the LHDA told this publication that “the diversion tunnels are essential to facilitate the construction of the Polihali Dam”.
“Their construction is an important element of the advance infrastructure works which started towards the end of 2018 with the awarding of the contracts for the Polihali North East Access road and the civils work at Katse and Mokhotlong. The advance infrastructure will largely be completed prior to commencement of construction of the Polihali dam and the Polihali to Katse water transfer tunnel.
“Diversion tunnels divert water away from the natural river bed to create a dry foundation and work area needed for the construction of a dam. Their construction usually goes along with the building of cofferdams, one upstream and one downstream of the proposed dam, which together allow the river flow to bypass the dam foundation area.
“In the case of the Polihali Dam, two diversion tunnels will be constructed to divert the waters of the Senqu River. Building two tunnels will increase the capacity to carry floods and will provide flexibility to work in one tunnel while the river flows in the other one.
“The tunnels, one seven metres in diameter and almost a kilometre in length, and the second, nine metres in diameter and almost a kilometre long, run parallel to each other from the intake point to the outlet downstream of the (Polihali) dam.”
The LHDA further said that the contractor (SCLC Polihali) would be on site before the end of this month and the work is expected to be completed in 18 months.
The SCLC Polihali Diversion Tunnel Joint Venture comprises of the following local and South African companies: Salini Impregilo, Cooperativa Muratori Cementistri CMC di Ravenna, CMI Infrastructure Ltd (all South Africa) and LSP Construction (Pty) Ltd. (Lesotho).
The Metsi a Senqu-Khubelu Consultants Joint Venture (MSKC), which includes Aurecon, Knight Piesold, Hatch Goba, SMEC (all South African companies) and FM Associates (Lesotho), designed the diversion tunnels and will also supervise the construction work.


Feather River Levee Setback Project
This project is a follow-on project to the recently constructed Bear River Levee Setback project although it is approximately three times the size of the Bear River project in terms of setback area and length of new levee (length of new levee = 5.7 miles).
Dr. Bowles was the project director under a previous company (not cbec) for the geomorphic and ecosystem enhancement section of this project for the Three Rivers Levee Improvement Authority (TRLIA) during the early stages of planning in 2006 and 2007.
Project feasibility and design commenced in 2006 with implementation expected in 2009. The levee setback project is the second of its kind in the Central Valley of California (after the Bear River Levee Setback Project, and includes multi-objective, holistic, floodplain management elements such as:
- Flood risk reduction, through protection of nearby development by the new setback levee, and reduction of the water surface elevation of peak flood events due to increased conveyance capacity provided by the increased floodplain area.
- Ecosystem enhancement opportunities through riparian restoration of the newly exposed floodplain.
Dr. Bowles specifically directed technical geomorphic reconnaissance and studies, including sediment transport analyses, to quantify the transport regime of the setback floodplain and associated main channel of the Feather River in comparison to the pre-project conditions.

With hydraulic valve body as carrier, the filling and solidification process of valve body casting were studied by combining theoretical analysis with numerical calculation, and the influence of casting defects on valve body strength was analyzed in depth.The research has important guiding significance for further understanding of valve body strength and reliability design and development of hydraulic valves.
(1) Predict the location and size of casting defects.Considering the complex internal structure of the hydraulic valve body, which leads to long production cycle, high production cost and poor casting quality, the filling and solidification process of the valve body casting is simulated by PROCAST software, the position and size of casting defects are predicted, and the position and size of casting defects of the valve body with different pouring temperature, different materials and structures are compared and analyzed.The optimum casting material and pouring temperature are sought to determine the optimum valve body structure, which provides basis for the design of hydraulic valve.
(2)Using PROCAST post-processing software to measure the position of casting defects and calculate the size, and then using the method of “artificial defects”, the casting defects are built in the valve body model by using three-dimensional modeling software, the stress values of valve body with shrinkage holes under different pressures are calculated by Workbench, and the fatigue characteristics of valve body are obtained by fatigue analysis under alternating loads, and the ideal values are compared and analyzed.Strength index of valve body and valve body with casting defects, and influence rule of casting defects on strength of hydraulic valve body are summarized.
(3)In addition to the high pressure load, the hydraulic valve body is subjected to thermal load due to throttling. By establishing watershed model of multi-way valve under different conditions, the flow field distribution and temperature distribution of hydraulic valve under different conditions are analyzed, and the calculated pressure and temperature loads are introduced into Workbench. The fluid-solid coupling method is used.The stress values of the multi-way valve under different conditions are obtained, and the strength indexes of the ideal valve body and the valve body with casting defects are compared and analyzed to reveal the influence of casting defects on the strength of the valve body.

A dynamical model for mean inlet pressure estimation in an implantable rotary blood pump is proposed. Noninvasive measurements of pump motor power (P), pulse width modulation, and impeller rotational speed (??) were used as inputs to the model. Linear regression analysis between estimated and measured inlet pressures obtained from in vivo greyhound data (N = 3) resulted in a highly significant correlation (R 2 = 0.957) and a mean absolute error (e) of 2.292 mmHg. Furthermore, the proposed model was stable which allowed accurate study and estimation of the transient response and the dynamics of the pump inlet pressure (P in).


Ukrhydroenergo says that the engine room of the Kakhovka hydroelectric power plant was blown up from the inside, rendering the whole plant irreparably destroyed.
The reservoir is estimated to be releasing water during the next four days.
"The uncontrolled fall of the water level in the reservoir is an additional threat to the temporarily occupied Zaporizhzhia NPP. Water from the Kakhovka reservoir is necessary for the plant to power its turbine capacitors and safety systems. The plant’s cooling pond is currently full. The Ukrainian staff at the ZNPP is monitoring all indicators," the company said.
As of 9:00 a.m., June 6, the water level in the kakhovka reservoir is rapidly falling, and the evacuation of people from the potentially flooded areas has begun.


Vakumat Pumping Unit
The Vakumat is a pumping set used, amongst other things, in agriculture for pumping liquid manure into and out of barrels. The compact-designed housing includes two wear-free pumps, which are not susceptible to dry-run failures. A self-suction liquid ring pump builds up a vacuum at first; as soon as the rotary pump on the suction side is flooded the actual pumping process starts. The pipe- and valve system between both pump monitors the suction process autonomously.

Hawk Measurement Sultan Acoustic Wave Level
Principle of Operation
Hawk Measurement Sultan Acoustic Wave Level uses the transmission of high powered acoustic waves ensures minimal losses through the environment where the sensor is located. Due to the high powered emitted pulse, any losses have far less effect than would be experienced by traditional ultrasonic devices. More energy is transmitted hence more energy is returned. Advanced receiver circuitry is designed to identify and monitor low level return signals even when noise levels are high. The measured signal is temperature compensated to provide maximum accuracy to the outputs and display.

JACKSONVILLE, Fla. – The U.S. Army Corps of Engineers Jacksonville District has awarded a construction contract for the reservoir component of the Indian River Lagoon-South’s C-44 Reservoir and Stormwater Treatment Area (STA) project in Martin County, Fla.
The $197 million construction contract was awarded today (Sept. 11) to Barnard Construction Co. Inc. from Bozeman, Mont. The contract involves the construction of a 3,400-acre reservoir that will store up to 15 feet of water and will provide 50,600 acre-feet (16 billion gallons) of storage capacity. Construction is anticipated to begin this winter.
“The reservoir is the largest component of the C-44 project and a key storage component of the entire Indian River Lagoon-South project,” said Orlando Ramos-Gines, Jacksonville District Senior Project Manager. “Getting this contract awarded is a major step forward towards being able to store local basin-run-off and improve conditions in the St. Lucie Estuary and Indian River Lagoon.”
The contract also includes the construction of the following features:
§ The 35,000-foot long Western Reservoir Perimeter Canal, which runs parallel to most of the northern, western, and southern embankments of the reservoir. It will be used to transmit surface runoff and seepage flow from the embankment internal drain and the trench drain systems.
§ A corresponding 50-foot wide spillway for the Western Reservoir Perimeter Canal that will discharge into the intake canal, which was completed as part of the Corps’ first construction contract for the project, in July 2014.
§ The 15,000-foot long Eastern Reservoir Perimeter canal, which runs parallel to the eastern embankment of the reservoir. It will convey runoff and seepage from the embankment internal drain and the trench drain system.
§ A reservoir discharge tower structure comprised of three slide gates to convey a maximum of 1,100 cubic feet per second (cfs) (600 cfs under normal operations) through two culverts to the system discharge canal.
§ Two miles of the system’s discharge canal that will convey flows from the reservoir through the Distribution Canal to the Eastern Stormwater Treatment Area (STA) Collection Canal.
§ The installation of several box culverts in various locations around project footprint to provide vehicular access across canals. Additionally, the reservoir embankment includes the construction of several boat ramps for access inside the reservoir.
“The reservoir contract will complement the construction already initiated by the State on the reservoir intake canal and associated Stormwater Treatment Area,” said Ramos-Gines. “Collectively, these features will work together to provide additional storage and treatment, while attenuating damaging flows discharged to the St. Lucie Estuary.”
In an effort to construct the project as expeditiously as possible, the South Florida Water Management District (SFWMD) has awarded construction contracts for the discharge canal, pump station and STA. The shared efforts on construction contracts will reduce the time needed to fully-construct the project by at least two years.
Construction of the C-44 Reservoir and STA is scheduled to be completed in 2020. Upon construction completion, up to two years of operational testing will occur.
Once all work is complete, the project will capture local run-off from the C-44 basin, reducing average nutrient loads and improving salinity in the St. Lucie Estuary and the southern portion of the Indian River Lagoon. It will provide, in total, 60,500 acre-feet of new water storage (50,600 acre-feet in the reservoir and 9,900 acre-feet in the STAs) and 3,600 acres of new wetlands.
The Indian River Lagoon is considered the most biologically diverse estuarine system in the continental United States and is home to more than 3,000 species of plants and animals. The C-44 Reservoir and Stormwater Treatment Area is the first component of the multi-billion dollar Indian River Lagoon-South project, an element of the Comprehensive Everglades Restoration Plan (CERP).

Montgomery Point Lock and Dam Ensures System Available During Low-Water Conditions
LITTLE ROCK, Ark.-- During this year’s unseasonably dry summer the McClellan-Kerr Arkansas River Navigation System functioned as designed ensuring a 9-foot channel for barge traffic moving through the system.
Because water levels on the Mississippi River dropped so low the crest gates at Montgomery Point Lock were used this summer for the first time since 2008.
Located on the lower section of the MKARNS near Tichnor, Ark. Montgomery Point Lock and Dam was put into service in 2004, solving the low-water problem in the area by eliminating the recurrent navigation restrictions and reducing dredging needs by more than 90 percent.
When the Mississippi River water levels start getting low the White River, which flow into the Mississippi, drops too.
Montgomery Point Lock and Dam features "first of its kind" hydraulically operated gates. When the tail water is at elevation 115 and rising, the dam gates are flat on the bottom of the river and barge traffic passes over the gates in the navigation pass spillway to minimize lockages saving time and money.
When the tail water is at elevation 115 and projected to fall, the 10 dam gates are raised to ensure a 9-foot pool behind the dam which forces barge traffic through the lock instead of over the gates.
It took many years of planning and construction to complete Montgomery Point Lock and Dam. However, if it had not been built, millions of dollars would have been spent on dredging the lower end of MKARNS to ensure the channel stayed open during dry weather years.
The design of Montgomery Point makes positioning the gates less labor-intensive for the lock operations crews, because all gate changes can be completed with the push of a button. The design also has most of the operating equipment housed in the gallery to keep it dry which cuts down on the damage due to weathering.
Another noteworthy design feature is that the entire lock and dam, except for the control tower is completely below the top banks of the channel. During very high water conditions, the structure is submerged, except for the control tower. Because of its location, the project was designed to withstand large fluctuations in the water surface elevation. The water surface at Montgomery Point has fluctuated from elevation 104 to 172.
Although the design is rarely used it paid off this summer by keeping the MKARNS flowing and the economy going. The same cannot be said for many of the Midwestern state’s river and streams.

State-owned power utility Elektroprivreda Srbije (EPS) has announced a tender to develop a preliminary design and feasibility study for the construction of a pumped-storage hydropower plant (RHE) Bistrica.
RHE Bistrica is part of a EUR 17 billion investment plan prepared by the Ministry of Mining and Energy. Nikola Rajaković, a professor at the School of Electrical Engineering in Belgrade and president of the Association of Energy Sector Specialists and Power Engineers of Serbia, told Balkan Green Energy News that the project is excellent because it is already partly prepared.
Elektroprivreda Srbije intends to obtain a preliminary design with a feasibility study to assess the profitability and possible role of the pumped storage hydropower plant within the power system of Serbia, the region, and beyond.
The deadline for submitting applications is January 28, 2022.
The preliminary design from 1981 was prepared by Energoprojekt-Hidroinženjering from Belgrade
Pumped storage hydropower plants produce peak energy to cover maximum daily consumption. They are also a solution for the variability of green power plants as they provide energy storage.
EPS has one such HPP – RHE Bajina Bašta, and RHE Bistrica would be similar. According to the tender documentation, RHE Bistrica would have four Frances-type units with a nominal (output) turbine capacity of 157.1 MW and a maximum (input) pump capacity of 167.9 MW.
RHE Bistrica would have a similar installed capacity as RHE Bajina Bašta
RHE Bajina Bašta has a maximum capacity in the generator mode of 614 MW and a maximum input capacity in the pump mode of 620 MW. Its average annual production is about 1,000 GWh.
According to the tender documentation, the preliminary design with feasibility study should be based on the preliminary design from 1981 prepared by Energoprojekt-Hidroinženjering from Belgrade and on the analysis and investment-technical documentation prepared by Energoprojekt Hidroinženjering and the Electricity Coordinating Center.
The Klak dam must be constructed on the river Uvac
Hydropower plant Bistrica would be a storage hydropower unit with a powerhouse near the right bank of the river Lim on the location between the Potpeć dam downstream from it and its hydropower plant Bistrica upstream.
The existing Potpeć reservoir is planned as a lower reservoir, while the upper one would be established by constructing a Klak dam downstream from the existing Radoinja dam.
Klak dam is located in the canyon of river Uvac, about five kilometers downstream from Radoinja. The new structure would be about 90 meters high, and the reservoir would extend all the way to the Radoinja dam.


NDRC green lights Jinsha River hydro project
Shanghai. January 21. INTERFAX-CHINA - The National Development and Reform Commission (NDRC) approved construction plans for the Ahai Hydropower Plant on the Jinsha River in Yunnan Province, the NDRC said on its Website on Jan. 20.
According to the China Electricity Council (CEC), the project will feature five 400-megawatt (MW) turbines and will be constructed by Jinsha River Hydropower Development Co. Ltd. The company was jointly established in 2005 by China Huadian Corp., China Huaneng Group, China Datang Corp., Haneng Holding Group and Yunnan Investment Group.
The project is the second hydro plant to receive NDRC approval to be built along the middle portion of the Jinsha River after the 2,400-MW Jin'an Bridge project got the go-ahead in August 2010. China plans to build eight hydro projects with 20.58 gigawatts (GW) of total installed capacity along this stretch of the river.


This project (known locally as "Twin Cities") is located on the Chehalis River in Lewis County, southwest Washington. It includes the cities of Centralia and Chehalis as well as the Interstate 5 (I-5) corridor. The project is designed to reduce flood risks in urban areas and to reduce the risk of flooding to the I-5 corridor. The Water Resources Development Act (WRDA) 2007 authorized construction of 13 miles of setback levees along the Chehalis and Skookumchuck Rivers, and modification of the Skookumchuck Dam to regulate flow during flood conditions.
After the devastating flood of 2007 in the Chehalis Basin, the State of Washington stepped forward as the non-federal project sponsor and signed a Design Agreement in June 2008. Significant floods occurred again in January 2009 closing I-5 for six days. The project is currently in pre-engineering and design phase. Fiscal Yar 2011 activities included updating the hydraulic information, cost estimates, economics, and re-analysis of required mitigation. These updates included the effects of the 2007 and 2009 floods. Results from this update determined the benefit cost ratio (BCR) for the project to be less than 1. The project as currently designed does not offer 100 year level of protection based on updated hydraulic data from recent floods.

CALIFORNIA IS CONSIDERING building a US$1.6B reservoir to store 2.3B m3 of water at the foot of the Coast range of mountains – more than twice the capacity of the Metropolitan Water District’s new Diamond Valley lake near Hemet in Riverside County, US.
The reservoir is among a number of proposed water storage projects that have won political backing recently. The diverse political support for dams would have been unthinkable just a few years ago. A long-standing stalemate over new dams has kept any new reservoirs from being built for three decades. However, political fallout from the state’s energy crisis is making Californians view such projects favourably.
Other water projects under consideration include enlarging existing dams at Lake Shasta near Redding, Millerton lake on the San Joaquin river near Fresno, and the Los Vaqueros reservoir near Livermore.

GNWQ series sewage cutting pump non-clogging submersible sewage water pump is suitable for 0-20 meters, large flow, medium and low head use, full head, low energy consumption. The product also adopts an easy-to-remove cutter head design, which can be replaced with different forms of cutter heads according to different use environments, including municipal and livestock farms. A large number of practical applications and laboratory tests have proved that the GNWQ submersible cutter sewage pump is superior to any current domestic sewage pump in terms of college and anti-clogging performance, achieving a perfect combination of high efficiency + non-clogging characteristics.
The submersible sewage slurry cutter pump used in the ESP device is a multi-stage centrifugal pump, which operates in a vertical position. Although their structure and operating characteristics have been developing for many years, their basic operating principles remain unchanged.
The generated liquid loses kinetic energy in the diffuser after receiving the huge centrifugal force generated by the high speed of the impeller, and converts kinetic energy into pressure energy in the diffuser.
The pump shaft is connected with the protector through the mechanical coupling at the bottom of the submersible cutter slurry sewage pump. The well fluid enters the pump through the inlet filter screen and is lifted by the pump stage.
Other components include radial bearings (shaft sleeves) distributed along the length of the shaft to provide radial support for the high-speed rotating pump shaft.
The optional thrust bearing bears part of the axial force generated in the submersible sewage water pump, but most of the force is absorbed by the thrust bearing of the protector.
1. Vortex impeller with non-clogging design;
2. Material of impeller and knife ring: high chromium stainless steel 420, hardness HRC49-52, good wear resistance;
3. Heavy duty bearing and SS420 shaft;
4. Double mechanical seal consists of two seals in series. The super wear-resistant mechanical seal made of silicon carbide ensures the best sealing effect.
