Circulating Range Constant Pressure Inverters
Circulating range constant pressure inverters.
These inverters are used with a centrifugal pump driven by a single phase induction motor and a pressure transducer, which is provided & already connected to the inverter, that detects the pressure of the pumped system. These replace all traditional systems such as pressure switch or flow switch and large pressure vessels which are no longer necessary.
Soft starts and stops guarantee a low current absorption which extends the motor life, provides quieter working and reduces water hammer. The logic control unit protects the system from the no flow and dry-running conditions or other dangerous electrical or mechanical conditions.

SAMBALPUR: After a delay of nearly two years, work on construction of the additional spillway of Hirakud Dam Project is likely to resume soon. The dam authorities will float a fresh tender with revised estimate for the project after approval of the State government. Chief engineer of Upper Mahanadi Basin Ananda Chandra Sahu said the bid documents have been sent to government for final approval following which a fresh tender will be floated for construction of the additional spillway.
The additional spillway was proposed after the Central Water Commission (CWC) gave recommendation to enhance the floodwater discharge capacity of all major dams to 1.5 times of their current capacity. Subsequently, Tata Projects Limited and AGE Group, Turkey were selected to jointly carry out the work. Work started in January 2019 but the two firms backed out of the project in February, 2020 alleging delay in handing over of land for the project by the government.
At the time when the companies withdrew from the project, around four lakh cubic metre soil had already been excavated. The firms had received Rs 12 crore out of the total budget for the work. However, their contract was later cancelled and there has been no progress on the project since then.
Sources said after revision of the project estimate recently, the bid document for floating fresh tender got administrative approval. Earlier, the estimated cost of the project was Rs 369.53 crore. Now, the revised estimate is Rs 634.21 crore. As per the project proposal, length of the additional spillway will be 91 metre and it will have five sluice gates. The width of the channel will be 300 metre and the length 1.9 km. The spillway channel will originate from near Gandhi Minar on the left dyke of the dam and meet Mahanadi river near Jawahar Udyan.
Currently, Hirakud Dam has 98 gates including 64 sluice and 34 crest to discharge floodwater. The existing discharge capacity of the 98 gates is 15 lakh cusec. The floodwater discharge capacity of the dam will increase to 18 lakh cusec after completion of the additional spillway project.

The basic structure of the centrifugal pump is composed of six parts are impeller, pump body, pump shaft, bearing, sealing ring, packing box. 1, the impeller is the core part of the centrifugal pump, its speed is higher than the force, the blade on the impeller plays a major role, the impeller in the assembly before the static balance experiment. The inner and outer surfaces of the impeller shall be smooth to reduce the friction loss of water flow. 2, the pump body is also called the pump shell, it is the main body of the pump. Plays a supporting and fixing role, and is connected with the bearing bracket. 3, the function of the pump shaft is to connect the coupling and the motor, the torque of the motor to the impeller, so it is the main part of the transmission of mechanical energy. 4. Plain bearing uses transparent oil as lubricant and lubricates it to the oil level line. Too much oil to seep out along the pump shaft, too little bearing and overheating and burning cause accidents! During the operation of the pump, the temperature of the bearing is 85 degrees, and the general operation is about 60 degrees.

Diagram of Centrifugal Pump Structure
Centrifugal pumps are widely used and widely used. In addition to industrial applications, centrifugal pumps are also widely used in agricultural irrigation, municipal water supply, circulating water supply in power stations, and urban pollution treatment. There are many types of centrifugal pumps. Although the structures of various types of pumps are different, the main components are basically the same. Now we mainly introduce the basic structure of centrifugal pumps.
The basic structure of a centrifugal pump is composed of eight parts: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, sealing ring, stuffing box, and axial force balance device.
1. The impeller is the working part of the centrifugal pump. It is one of the important parts of the centrifugal pump to realize the liquid transportation by relying on its high-speed rotation to do work on the liquid. The impeller is generally composed of three parts: wheel, blade and cover. The cover of the impeller is divided into a front cover and a rear cover. The cover on the side of the impeller mouth is called the front cover, and the cover on the other side is called the rear cover. The stainless steel impeller produced by Zhonglian Pump is made of standard 304 material, using the most advanced stainless steel plate stamping forming and laser welding technology. After the stainless steel plate is stamped, it is directly welded by laser precision.
When the centrifugal pump is started, the pump shaft drives the impeller to rotate at a high speed, forcing the pre-filled liquid between the blades to rotate. Under the action of inertial centrifugal force, the liquid moves radially from the center of the impeller to the outer periphery. The liquid gains energy in the process of moving through the impeller, the static pressure energy increases, and the flow velocity increases. When the liquid leaves the impeller and enters the pump casing, it slows down due to the gradual expansion of the flow passage in the casing, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipeline in a tangential direction.
2. The pump body is also called the pump housing, which is the main body of the water pump. Play a supporting and fixing role, and connect with the bracket for mounting the bearing. The volute refers to a spiral flow passage with a gradually increasing cross-sectional area from the impeller outlet to the next stage impeller inlet or to the pump outlet pipe. The flow channel gradually expands, and the outlet is a diffuser tube. After the liquid flows out of the impeller, its flow rate can be gently reduced, so that a large part of the kinetic energy is converted into static pressure energy.
3. The function of the pump shaft is to connect the motor with the coupling, and transmit the torque of the motor to the impeller, so it is the main component for transferring mechanical energy. One end of it is connected with the motor shaft through a coupling, and the other end supports the impeller for rotating motion. The shaft is equipped with components such as bearings and axial seals.
4. The role of the shaft sleeve is to protect the pump shaft, so that the friction between the packing and the pump shaft is transformed into the friction between the packing and the shaft sleeve, so the shaft sleeve is an easy-wear part of the centrifugal pump.
5. The bearing plays the role of supporting the weight and bearing force of the rotor. Rolling bearings are mostly used in centrifugal pumps. The outer ring and the bearing seat hole adopt the base shaft system, and the inner ring and the rotating shaft adopt the basic hole system. The national standards of the matching category have recommended values and can be selected according to specific conditions. Bearings are generally lubricated with grease and lubricating oil.
6. The guide wheel is a fixed disk. The front side has forward guide vanes wrapped around the outer edge of the impeller. These guide vanes form a diffuse flow channel. Guide leaf. After the liquid is thrown out from the impeller, it enters the guide wheel gently, and continues to flow outward along the forward guide vane. The speed gradually decreases, and most of the kinetic energy is converted into static pressure energy.
7. The sealing ring is also called the leakage reducing ring. In order to reduce internal leakage and protect the pump casing, a removable sealing ring is installed on the casing corresponding to the entrance of the impeller.
8. The stuffing box is mainly made of packing, which prevents the water flow in the pump from flowing outside and the outside air from entering the pump. Always maintain the vacuum in the pump! When the pump shaft rubs against the packing to generate heat, it is necessary to inject water into the water seal ring by the water seal pipe to cool the packing!
9. Axial force balancing device. During the operation of the centrifugal pump, because the liquid enters the impeller under low pressure and flows out under high pressure, the pressure on both sides of the impeller is unequal, and the axial thrust directed to the inlet direction is generated. It will cause the rotor to move in the axial direction, causing wear and vibration. Therefore, an axial thrust bearing should be installed to balance the axial force.

Liquid-cooled heat sink (cold plate) used for power electronics cooling is numerically studied. Thermal performance and hydraulic resistance are analyzed, with emphasis on geometric construction of cooling channels. Two heat transfer enhancing channel shapes are investigated, such as alternating elliptical channel and alternating rectangular channel (AR-C). Their performances are compared with that of three traditional straight channel shapes, as straight circular channel, straight elliptical channel, and straight rectangular channel. A heat sink with uniform and discrete heat sources is studied. Thermal and hydraulic characteristics in the heat sink are simulated using computational fluid dynamics approach, with water as coolant. The results show that the AR-C has the highest thermal performance with a little penalty on pressure drop, considering fixed channel hydraulic diameter and coolant volumetric flow rate. Geometry optimization is investigated for the AR-C, as well as the effect of channel density. It is found that higher channel density can improve both thermal performance and hydraulic resistance. It is concluded that alternating channel can improve cold plate performance and should be taken into application to power electronics cooling.

Working principle of garden pump
Garden pump is a common type of water pump, mainly used for garden irrigation, pond circulation, fountains and other water feature projects.
The working principle of a garden pump is to drive the impeller to rotate through an electric motor,
which sucks water into the pump body and then discharges it through the outlet.
The main components of garden pumps include motors, pump bodies, impellers, seals, etc.
The motor is the power source of the garden pump, which converts electrical energy into mechanical energy through a power source and drives the impeller to rotate.
The pump body is the main part of the garden pump, which is usually made of materials such as cast iron and stainless steel, and has good corrosion resistance and durability.
The impeller is the core component of the garden pump, which generates centrifugal force through rotation, sucks water into the pump body and pushes it towards the outlet.
The seal is a key component of the garden pump, which can effectively prevent water leakage and ensure the normal operation of the pump.
The working principle of the garden pump is based on centrifugal force. When the motor starts, the impeller begins to rotate, generating centrifugal force.
Due to the centrifugal force, water is sucked into the pump body and pushed towards the outlet.
In this process, the sealing element plays a crucial role in effectively preventing water leakage and ensuring the normal operation of the water pump.
The working principle of the garden pump is very simple, but its application range is very wide.
It can be used for garden irrigation, pond recycling, fountains and other waters cape projects, as well as for household and industrial water use.
When using a garden pump, it is necessary to pay attention to maintenance and upkeep, regularly clean the pump body and impeller,
and check whether the seals are intact to ensure the normal operation of the pump.

Description for Koysha Hydropower (Ethiopia)
Koysha (2’160 MW, under construction) is the fourth hydropower plant of Omo/Gibe river cascade in Ethiopia, comprising Gilgel Gibe (200 MW), Gibe II (420 MW) and Gibe III (1’870 MW), all currently in operation.
Koysha is a step forward in the development of the entire hydropower potential of the Omo river and represents a realization of the large-scale vision started more than 25 years ago with the design of Gilgel Gibe hydroelectric power plant. It testifies our long-term commitment for the progress of Ethiopia’s energy sector.
The project includes several outstanding examples of value engineering and design optimization, carried out by SP throughout the entire design and construction period of the hydroelectric power plant.
The layout includes an RCC gravity dam, approximately 180 m high, that creates a large reservoir of about 6’500 Mm3.
Floods are discharged by means of a gated spillway located on a saddle at the left side of the RCC dam: a large channel with a flip bucket designed for releasing a flow of about 13’100 m3/s in a plunge pool adjacent to the river, downstream of the powerhouse.
The dam is crossed by three steel penstocks feeding an open-air powerhouse, one of the intakes is lowered to allow early generation using the first two units during the first impounding.
The project includes two 6 m diameter middle level outlets embedded in the dam body allowing to control the reservoir level during the first impounding, release artificial/ecological flows and lowering the reservoir level for inspection/maintenance needs.
The river diversion layout includes two concrete culverts on the right side of the river, aimed to divert the river during the dam construction and designed to discharge up to 3’000 m3/s, and an upstream composite RCC/rockfill cofferdam.
Both the river diversion layout and the energy-generation operating rules of Koysha have been optimized taking advantage of the large flow regulation capacity of the upstream Gibe III project.
Tandem operations of the two projects allow to maximize energy generation and provide great flexibility guaranteeing power supply during both dry season and peak-demand period.
The power house is located on the left side of the river, housing eight Francis turbines generating 2’160 MW, together with erection bays and control building. Step-up transformers are located behind the powerhouse. Each unit is connected to three single-phase 400 kV transformers, for a total of 24 transformers that are linked through overhead lines to the 400kV Switchyard.
- RCC Gravity Dam ( H = 170 m, crest L = 990 m )
- U/S RCC & Rockfill Cofferdam ( H = 42 m, L = 330 m )
- Gated Spillway ( Q=13'100 m3/s )
- Penstocks ( No. 3, L = 0.65 km )
- Power House ( open-air, No. 8 Francis turbines, IP = 2'160 MW )
- Switchyard ( 400kV, no. 14 bays )

KATHMANDU, August 6: The water level in Koshi River has started to recede since this afternoon. Officials said the situation in Koshi River is now risk free now.
According to the Chief District Officer of Sunsari Indra Dev Yadav, the water flow in Koshi barrage is now 215,825 cusecs. He said the water level in Barah Chhetra has been measured even lower than that of Koshi barrage.
Yadav said all 33 gates of Koshi barrage have been left open. “As the water flow has also reduced in the area now, it can be considered risk free now,” he said.
Earlier on Saturday morning, the Meteorological Forecasting Division had issued a high alert notice, citing a fast rising water level in Koshi River.

Opening of VLH turbines
On the basis of a new design, the VLH turbines are liftable during floods to free the openings. Modeling helped to check the risk of sedimentation under the VLH and validate solutions to eliminate any risk of obstruction with the lowering of the turbines at the bottom of the opening.
The device of the instream flow release of the plant has been modeled. This model was made to find a solution to the work carried out with the aim of settling water in the last basin to allow control of the overflow water level.


This paper presents the numerical modelling of a novel vertical axis tidal turbine that incorporates localised flow acceleration and variable-pitch blades. The focus is to develop a computational fluid dynamics model of a 1:20 scale model of the device using ANSYS® Fluent®. A nested sliding mesh technique is presented, using an outer sliding mesh to model the turbine and additional inner sliding meshes used for each of the six blades. The turbine sliding mesh is embedded in an outer static domain which includes the flow accelerating bluff body. Modelled power performance and velocity data are compared with experimental results obtained from scale model tests in a recirculating flume. The predicted power curves show general agreement with the measured data; the relative difference in maximum performance coefficient for example, is just 5.7%. The model also accurately reproduces measured flows downstream of the turbine. The verified and experimentally validated model is subsequently used to investigate the effects of the variable-pitching and number of blades on device performance.

U.S. Army Corps of Engineers
Digital Engineering provided engineering design for the construction of approximately 19,000 linear feet of a T-Wall floodwall barrier separating the Parishes of St. Charles and Jefferson. The new floodwall replaces an existing structure which consisted of bothT-Wall and I-Wall monoliths. One of the biggest design challenges was to maintain existing flood protection from the original wall during construction of the new floodwall. It was built only 20' to 30' away from the face of the existing wall. The design needed to carefully weave the H-piles for the new floodwall between reinforced concrete piles that were stabilizing the existing floodwall.
As Prime Firm, DE was responsible for the preparation of final plans and specifications, test pile program, right-of-way issues, and construction access drawings. The project also included the design of land-side subsurface drainage along the floodwalls.
Construction features included the construction of the T-Wall beneath the I-10 overpass and the accommodation of the 84 inch diameter discharge tubes from the Parish Line Pump Station through the new T-Wall monoliths. An additional design challenge was to accommodate a pile spacing which would not conflict with the existing battered piles which were spaced on 8foot centers.
The project was bid in two phases with a total construction cost of over $120 million. Both projects were completed in 2012. DE received an overall ACASS rating of “Very Good” for the project.The Rating Official remarked “The A-E produced a very good product under the tight duration and changing design criteria.”
In June 2013, this project was honored by Engineering NewsReward as a Global Best Project.

…Samia to launch completed key stage
CONSTRUCTION of the Julius Nyerere Hydropower Power Project (JNHPP) is taking a new shape with President Dr Samia Suluhu Hassan slated to officiate at the opening of the diversion channel that will direct water into the dam for generation of electricity.
At a historic event to be held on Thursday, this week, Dr Samia is expected to press a button to signal opening of the diversion channel for the 2,115 megawatts (MW) project being built at a cost of 6.55tri/-.
The occasion is expected to be witnessed by over 300 guests from both the governments of Tanzania and Egypt.
Speaking to journalists at the construction site of the mega project to be built on River Rufiji yesterday, the Minister for Energy, Mr January Makamba, said the project has been completed by 78.68 per cent as of November, this year.
“The opening of the diversion channel by President Samia signals a significant momentum in implementation of the project, adding that the remaining part is switching on the turbines to start generating power,” Mr Makamba explained.
Mr Makamba elaborated further that the opening of the diversion channel is a significant step to pave the way for filling water into the dam to start generating power at the largest hydropower project in the region.
He added: “The dam to be used to generate water at the project measures about 916 km2 and it will be more of a lake than a dam given its vast size.”
Apart from generating electricity, the project is also crucial for controlling frequent flooding along the river and boosting tourism, since it has been built within the Julius Nyerere National Park where River Rufiji traverses.
The Minister mentioned other benefits associated with the dam at JNHPP as fishing as well as irrigation farming.
Mr Makamba elaborated that unlike other hydropower plants which depend on flowing water to generate electricity, the water to be stored at the JNHPP dam can produce electricity for three consecutive years even when there would be no rain.
“There are some people who have been doubting sustainability of JNHPP due to effects of climate change, but the truth is there will be enough water which can be used for up to three years in case there are no rains to fill up the river.
“For instance, Kihansi hydropower which depends on flowing water has an installed capacity to produce 180 megawatts but it only generates 17 megawatts at present, while Mtera which has a dam generates at full capacity at 80 megawatts despite lack of rains,” he explained.
To ensure smooth implementation of the project, the government has during the current fiscal year 2022/2023, allocated 1.44 tri/- for the JNHPP.
The project’s Egyptian contractors – Elsewedy Electric and Arab Contractors have on different occasions pledged to complete the project on time.
Electricity generated from the project will be transmitted via a new 400kV high voltage power line to a substation, where the power will be integrated into the national power grid.
The JNHPP is expected to transform the country through the generation and supply of reliable electricity for both domestic and industrial use, besides making the country improve in its manufacturing sector.
Implementation of the project is part of Tanzania’s Third National Five-Year Development Plan (FYDP III) spanning between 2021/22 and 2025/26 and the ruling CCM party manifesto for 2020-2025.
The JNHPP will be the largest electricity scheme installed in East Africa and among the largest in Africa in comparison to Egypt’s Aswan High Dam (2,100 MW), Mozambique’s Cahora Bassa Dam (2,075 MW) and Angola’s Lauca Dam (2,069 MW).

|Title||Groundwater remediation design using a three-dimensional simulation model and mixed-integer programming|
|Publication Type||Journal Article|
|Year of Publication||1995|
|Authors||Sawyer C.S, Ahlfeld D. P., King A.J|
|Journal||Water Resources Research|
A three-dimensional groundwater flow management model for making decisions on the design of hydrodynamic control of a groundwater flow system using a combination of extraction and/or injection wells is developed. The model takes into account constraints imposed on the system to stop the horizontal spread of contaminants and to ensure a net upward flow in areas where downward vertical gradients exist. The mathematical formulation of the groundwater remediation problem as a mixed-integer model and the strategy for solving the model are presented. Numerical results are presented for the Toms River Plant site, which is modeled as a five-layer aquifer system with interconnecting aquitards. A sensitivity analysis on the relative magnitude of the continuous operating costs and the fixed-charge costs is also presented.
