Small Sight Feed Valves allow visual observation of the liquid stream, with the volume of flow controlled by an adjustable precision control needle valve. These units are principally used on gravity or pressure lubricating systems for bearing lubrication on machinery. Their use can be extended to any application requiring adjustable, visible flow control.
The inlet is located on one side of the valve body and the needle valve adjustment is on the opposite side. The outlet is on the bottom of the unit. The valve is vented to ensure proper flow and prevent airlock. Solid gasket designs are available for sealed pressure applications.
This handwheel valve (tamperproof is also available) withstands up to 225° F and 125 PSI inlet to orifice pressure with vented sight chambers. The valve features a steel plated valve body and needle assembly, glass sights, Buna-N seals, and a 1/16" diameter port. Total Height of the valve is 2 5/32”.
The valve has a 1/4” male NPT inlet and a 1/4” male NPT outlet.

- Vertical pump test loop; Two-phased flow test loop; Electric Submersible Pump
thesis / dissertation description
A new centrifugal pump has been devised to handle two-phase flow. However, it requires full scale testing to allow further development. Testing is required to verify performance and to gain information needed to apply this design in the field. Further, testing will allow mathematical models to be validated which will allow increased understanding of the pump's behavior. To perform this testing, a new facility was designed and constructed. This facility consists of a closed flow loop. The pump is supplied by separate air and water inlet flows that mix just before entering the pump. These flows can be controlled to give a desired gas volume fraction and overall flow rate. The pump outlet flows into a tank which separates the fluids allowing them to re-circulate. Operating inlet pressures of up to three hundred PSIG will be used with a flow rate of twelve hundred gallons per minute. A two-hundred fifty horsepower electric motor is used to power the pump. The loop is equipped with instrumentation to measure temperature, pressure, flow rate, pump speed, pump shaft horsepower, shaft torque, and shaft axial load. The pump itself has a clear inlet section and a clear section allowing visualization of the second stage volute interior as well as numerous pressure taps along the second stage volute. This instrumentation is sufficient to completely characterize the pump. Design and construction details are provided as well as a history of the initial operating experiences and data collected. A discussion of lessons learned is given in the conclusions. Future projects intended to use this facility are also given. Finally, detailed design drawings are supplied as well as operating instructions and checklists.


Chief Joseph Dam is located in North Central Washington near the town of Bridgeport. It sits on the Columbia River and construction began in 1949 but the power generating units were not completed until 1958.
Fun Facts About Chief Joseph Dam
-Chief Joseph Dam is a concrete-gravity dam.
-Chief Joseph Dam is 236 feet high.
-Chief Joseph Dam measures in at 5,962 feet long.
-The width of the dam is 22 feet at the top and 164 feet at its base underneath the water of the Columbia River.

The Kaplan type turbine(also called axial flow turbine) is mostly suitable for hydropower stations with medium or low head. The Kaplan type turbines can be divided into fixed blade and rotating blade(double regulated Kaplan turbine) according to its structure. The fixed blade type is mainly used for small hydropower plant with medium and small capacity, small variation in load. While rotating blade type is mainly used for hydropower plant with medium and big capacity, big variation in load.
The Kaplan type turbines supplied by Bochi are ranging from 2 to 65m in water head, 0.2 to 100MW in capacity and 1 to 7m in runner diameter.


Powerline FRS Interim Dam Safety Measure
- Owner: Flood Control District of Maricopa County
- Location: Maricopa County, AZ
- Completion Date: 2 Oct 2013
- Core Competencies: Earthwork
This Powerline Interim Dam project was constructed to help protect an existing earthen dam structure and the citizens living downstream of the structure. The large earthmoving project included 1.3 million CY of excavation, material processing, and placement. The detailed specifications included specific parameters for embankment fill as well as a central sand filter that was constructed in the center of the earthen dam structure on a 1.5:1 slope. The project required working in conjunction with multiple agencies to realize the goals of meeting the project schedule, budget, and strict specifications to ensure public safety.


Total: $13.5 million, funded by three levels of Government:
$6.745 million Federal Government
$5 million State Government
$1.755 million. Douglas Shire Council
At an estimated cost of $13.5 million, the construction of a new 20ML water reservoir in Craiglie, will be the single largest capital works project undertaken by Douglas Shire Council.
The reservoir is located on land in Craiglie off Ferraro Road which was purchased by Douglas Shire Council specifically for the water reservoir.
This location is 53 metres above sea level which is significantly higher than the 6 metres above sea level of the existing reservoir in Craiglie.
The project includes the construction of five kilometres of dedicated inlet and outlet mains and a new 640 metre access road.
The Contractor is Koppens Development Pty Ltd.
Construction commenced in May 2017 and completion is anticipated by September 2018.


Tank differential pressure transducer used for sealed stroage tank
In order to further improve the seal of sealed storage tank, tank differential pressure transducer is indispensable. In recent years, most sensor manufacturers have been developing new pressure level sensors to measure the pressure and level of sealed storage tanks, but these new products have been marketed without severe environmental measurements, resulting in a bad reputation.
This tank differential pressure transducer is not a so-called “high-tech” pressure sensor, its main function is to calculate storage top and bottom of the pressure difference, its installation method as shown in the figure below, under normal circumstances, a differential pressure sensor is installed in the bottom of the storage tank, and the other is a drainage pipe connected to the storage tank. The pressure difference between the two ends is used to calculate the level change in the tank, so as to prevent the liquid in the tank from volatilizing or being oxidized.
I believe that some people are concerned about the stability of the differential tank pressure transducer. In fact, its high and low pressure values are in the range of 5 to 40bar, which is basically the pressure level suitable for most sealed storage tanks.

Introduction and analysis of check valve
date：2018/8/10 10:36:02 source：
Check valve is a valve which is automatically opened and closed by the flow of the medium itself. It is used to prevent the reverse flow of the medium. It is also called a reverse check valve, a one-way valve, a countercurrent valve, and a back pressure valve. Check valve is an automatic valve, its main role is to prevent medium backflow, prevent pump and drive motor reversal, as well as container media release.
The opening and closing parts open or close by themselves with the force of the medium flow to prevent the medium from flowing backward is called a check valve. Check valves belong to automatic valves. They are mainly used for pipes with unidirectional flow of media. Only one medium is allowed to flow in order to prevent accidents.
Check valves can be divided into three types according to their structure: lift check valve, swing check valve and butterfly check valve.
1. lifting type check valve is divided into vertical and horizontal two kinds.
2. Swing check valve is divided into single-valve, double-valve and multi-valve.
3. butterfly check valve is straight through.
The above several kinds of check valves can be divided into thread connection, flange connection, welding connection and clamp connection.
Check Valve: According to the structure, it can be divided into three types: lift check valve, swing check valve and butterfly check valve. Lift check valves can be divided into vertical and through type. Swing check valves are divided into three types: single-valve, double-valve and multi-valve. Butterfly check valve is divided into butterfly double valve and butterfly type single. The above check valves can be divided into four types: threaded connection, flange connection, welding and clamp connection.
Matters needing attention
1. Do not let the check valve bear the weight in the pipeline system, the large-scale check valve should be supported independently, so that it is not affected by the pressure produced by the pipeline system.
2. When installing, pay attention to the direction of media flow should be consistent with the arrow direction marked by the valve body.
3. Lifting vertical disc check valve should be installed in vertical pipe.
4. Lifting horizontal valve should be installed in horizontal pipe.

ArmInfo. The Mejlis of Iran at a meeting on April 18 by 162 votes in favor, 5 against and 5 abstentions approved a bill on the construction of a hydroelectric power station on the Araks River. This is reported by the Armenian Embassy in Iran.
"On April 17, the Mejlis at a public meeting decided to start discussions with Armenia on the construction of a hydroelectric power station on the Araks River." It is noteworthy that the program for the construction of the Meghri HPP has been on the agenda of economic cooperation between Armenia and Iran for many years, "the Armenian diplomatic mission said in Iran.
The Meghri hydropower plant was previously considered the most promising joint Armenian-Iranian project. Although the parties have come to the final stage of the project and announced the start of construction in November 2012, the work has not been started yet because of the limitations of Tehran because of the sanctions. If the project is completed, the station will become the largest in the Transcaucasus. Under the project, the construction of a $ 323 million facility will be financed by the Iranian investment company. Armenia will pay for its part of the project with electricity produced at the hydroelectric station itself, and after 15 years the hydroelectric power station will be transferred to the Armenian side.
While the Armenian-Iranian economic relations can not move from the dead point, after the lifting of sanctions, economic ties between Tehran and Baku sharply intensified. The Iranian parliament approved a bill on the joint construction of two hydroelectric power stations with Azerbaijan. The bill allows construction of power plants near the Araks River in the border area, in the Iranian city of Marazad and the Azerbaijani city of Ordubad. The document provides for cooperation in the construction of power stations at the dams of Khoda Afarin and Gyz Galasy, on the Araks River, as well as the construction of the Ordubad Power Station on the Azerbaijani side and the power plant in Marazada on the Iranian side. The ArmInfo agency reported that if the project is implemented, the water volumes for the Meghri hydropower plant in Armenia may simply not be enough. Earlier, adviser to the Minister of Energy Infrastructures and Natural Resources of Armenia Areg Galstyan stated that due to environmental problems related to the reduction of water volumes in the Araks River, as well as the increase of water intakes from Turkey in the northern part of Armenia, it was necessary to revise this project in the direction of power reduction. If initially it was planned to build two stations (Meghri - Armenia, Karachilar - Iran) for 130 MW each and a total power generation of about 850 million kW per year, now the option is considered with a capacity of 100 MW. In this regard, the diameter of the tunnel has been changed, along which water will flow between the two hydroelectric power stations.

Review of Reports on Santee River System, North Carolina and South Carolina.
CORPS OF ENGINEERS CHARLESTON SC CHARLESTON DISTRICT
Pagination or Media Count:
Local interests expressed the desire for a shallow draft navigation channel from Charleston to Columbia, South Carolina, a distance of approximately 170 miles. Shallow draft navigation presently exists for approximately 120 miles of this distance. This was made possible by construction of the Santee-Cooper hydroelectric project which constructed dams across the Santee River and Cooper River and formed large fresh-water lakes. Also constructed in the dam on Cooper River was a 60 x 180 navigation lock at Pinopolis, South Carolina. The most practical plan of improvement consists of canalization of the Congaree River to Columbia by a series of 3 locks and dams. Consideration was given in the design of the structures to the prevention of flooding of the extensive forested areas along the river and to the unimpeded, upstream migration of the striped bass population during the spawning season and the downstream transport of the maturing eggs. Plan A considered lock sizes of 84 x 600 for the Congaree River and would include a new lock of the same dimension to replace the existing lock at Pinopolis. Plan B considered lock sizes of 84 x 400 for the Congaree River and extension of the Pinopolis lock by 58 feet. Commercial navigation on the Charleston to Columbia waterway has been practically nil for the past 15 years. Prospective traffic which could be generated was found to be insufficient to justify the construction of the project.

Stage 11 is a true delivery of water on demand aqueduct. The San Carlos lake has a storage capacity of a million acre-ft, the ideal buffer from the peak power demand driven uphill stages to the major delivery stage. San Carlos lake is now mostly empty, but will be normally filled to 85% of capacity, slightly less in advance of the winter snow melt. The Lake would look like this:
The Coolidge dam is now decommissioned, the lake is too often empty and the dam suffered damage in the power plant and it was no longer economical to produce power. The retrofitted dam will have a power generation capacity of up to 17,000 cfs the top of the dam is at 2535 ft, the typical water level is at 2500 ft and the drop is 215 feet, giving a maximum power output of 275 MW. In the first pass, the maximum output is 8,500 cfs , and the maximum power output is 135 MW.
From there the stream follows the Gila River to the East diversion dam and connects to the Tucson leg of the CAP canal, and delivers 600 cfs of water. It it then disconnected to the bottom of the canal.
Whats in it for Arizona? Besides having a reliable flow, Gila river will again be good for fishing if stocked and it will deliver 600 cfs of reliable sweet Mississippi and Arkansas river water to the Tucson area. When fully built out it will deliver up to 275 MW of power.

Proposed 600MW plant would be built next to existing pumped hydro station inside Argyll’s highest mountain and help provide critical balancing services to grid. Drax has announced it has started the planning process for a new underground power plant at its existing pumped storage hydro power station in Argyll that will more than double the facility’s generating capacity. The UK power company said the project would be built within a hollowed-out cavern just to the east of an operational 440GW pumped storage hydro storage station inside Argyll’s highest mountain, Ben Cruachan. Drax said the proposed 600MW power plant would provide “critical” storage capacity that would help balance Scotland’s electricity grid as more renewable generation comes online and the country works towards it aim of achieving net zero emissions by 2045. The project will generate enough power for around a million homes and bring the overall capacity of its ‘Hollow Mountain’ Cruachan power station to 1.04GW, it added.
Business Green 24th June 2021 read more »
Will Gardiner, Drax’s chief executive, said: “Last year, the UK’s lack of energy storage capacity meant wind farms had to be paid to turn off and we lost out on enough renewable power to supply a million homes. We need to stop renewable power from going to waste.” Work on the project could begin as soon as 2024 and the plant could be operational by 2030.

Nakhon Si Thammarat’s Bt320m reservoir to be completed in 2022
A Bt320-million project to develop a 1,000-rai reservoir in Nakhon Si Thammarat to provide enough water for four villagers will be completed in 2022, a deputy director general of the RoyalIrrigation Department said on Thursday.
Thaweesak Thanadechophol visited the Thung Thap Nai project in Tambon Laem in Nakhon Si Thammarat’s Hua Sai district.
The project was initially aimed at preventing flooding by having the reservoir absorb flood water.
Thaweesak said his department has received complaints that Moo 4, Moo 7, Moo 8 and Moo 9 villages did not have enough water for daily use and farming so the Tambon Laem Administrative Organisation sought the budget for further digging the reservoir, pumping stations and 30km irrigation pipes to the four villages.
Thawee said his department has received the budget of Bt320 million for carrying out the project from the 2019 fiscal year and the project is scheduled to be completed in 2020.
He said the 51st Army Engineering Battalion has been assigned to carry out the project.
As part of the project, the battalion will dig the bottom of the reservoir to be four metres deep throughout and the battalion will also build 4.5-metre earth embankment with a 25-metre width around the reservoir with a length of 6km.
He said six pumping stations will be built.
Once completed, the project will be able to irrigate 6,500 rai of rice fields and 100 rai of vegetable fields in the four villages throughout the year, Thaweesak added.


The project consisted of the channelization of the Guayanilla River for the control of flooding in the Guayanilla flood plain. Some major items where the excavation and dewatering for a diversion channel and main river channels. Included in the contract where various types of stone revetment, filter materials and core stones which had to be mechanically processed at a quarry location 20 miles away.

Pump Model: SG/150E
The SG range of dredge and gravel pumps is designed to provide continuous pumping of highly abrasive slurries containing large particles at high maintained efficiencies with low maintenance and ownership costs. The impeller fitted to our SG heavy duty gravel pumps is the closed type with three vanes, which allow the impeller to pass large rocks. The heavy-duty dredge pump is specifically designed for low head duties such as hopper dredging and barge loading.
The dredge pump is one of the main components of the dredger, and it is critical for achieving production. Dredge pumps also have the biggest power consumption during operation so efforts to reduce the pump’s power needs through smarter design are critical.
Features of Sand Dredging Pumps:
Enhanced Performance; Enhanced Efficiencies; Enhanced Abrasion Resistance
Longer casing life- The large volume of the casing reduces internal velocities resulting in reduced wear;
Lost production time is reduced and screening is avoided- Because the internal proportions of the Dredge and Gravel pump ranges allow extraordinary large particles to be passed.
Long component life with no need for wear rings- The special shape of the impeller vanes and casing combine with side sealing vanes to reduce recirculation down the front of the impeller and exclude abrasive solids from between the impeller and casing.
Reduced leakage and wear- Side sealing vanes on the shaft side of the impeller reduce gland pressure and intrusion of solids into the gland area.

Kathmandu, April 20
Tanahu Hydropower Project, which is going to be developed under the assistance of the Asian Development Bank (ADB), has distributed Rs 211 million as compensation to the land owners of reservoir site.
The 140-megawatt storage project had distributed Rs 156.8 million to the landowners of the affected area immediately after the land compensation distribution was started in mid-February this year. The government has allocated a total of Rs 420 million for land compensation purposes of the project in this fiscal.
The project has to acquire 2,000 ropanis of land at Bhimad, Majhkot, Rishing Ranipokhari, Sabhung, Bhagawatipur, Kotdurbar, Jamune and Chhang of Tanahun district for the reservoir and the total land compensation is expected to hover around Rs 600 million. The upper bed of the dam will spread over 25 kilometres. Issuing a statement, the project has said that it will be able to mobilise entire allocated fund in this fiscal.
This project will build a dam with a height of 140 metres in Byas Municipality of Tanahun district. The 1,203-metre long tunnel will pass along the right bank of the Seti River for electricity generation from the underground powerhouse at Kunaute. The powerhouse will have two turbines with capacity of 70 megawatts each.
After generating the electricity, the water will again be diverted to Seti River through a 190-metre tunnel.
The project has expected to hire construction contractor by mid-October this year and is scheduled to be completed by December 2022. To evacuate power to the central grid, construction works of 37-km transmission line from the powerhouse site to Bharatpur substation is underway. The project can be operated for six hours in full capacity in the winter season, which will produce 58.77 billion units of electricity per annum in first 10 years of operation and 48.99 billion units per annum after that.

The Roendahl Canyon is located in the upstream region of the River Mais east of Mellvere.
In ancient times the River Mais often flooded, causing great damage to cities downstream. Now water levels are controlled using the dams and flood gates built in the canyon. It recently became known that the frequent flooding of the River Mais was largely due to excessive timber logging in the middle ages, reducing the water-holding capacity of the surrounding area. The government is now considering a replanting program.

Abstract: Crosscurrents in the Copeland Cut Reach of the Wiley-Dondero Canal make navigation difficult during periods of high flow with accompanying low water levels. The problem area is located in Lake St. Lawrence approximately 3 miles west of Eisenhower Lock. A TABS-2 numerical model reproducing a portion of Lake St. Lawrence from Wilson Hill-Ault Islands downstream to Eisenhower Lock, Long Sault Spillway Dam, and Moses-Sanders Power Dam was used to investigate current patterns in the problem area and the distribution of flows through the system. The model was used to evaluate plans for reducing the magnitude of the crosscurrents by altering the distribution of flows through the system. The results of this investigation showed that significant reductions in crosscurrent magnitude could be achieved by closure of a river channel downstream of the problem area. A physical model study has been proposed to refine these plans. The numerical model will be used to generate boundary conditions for the physical model.

For our Thermic fluid TP66 application we are used DP transmitter for flow measurement. Orifice assembly is used as a flow element.
Currently we are facing flow variation issue in transmitter. The flow is without pressure and temperature compensation. There is 25-30% in flow value when we are comparing it with pump flow. Pump flow, we are deriving from motor current as well as inlet and outlet pressure.
Flow meter is showing 145 m3/hr and as per pump curve it should be 190 m3/hr. Whenever i check flow value wrt DP, it matching perfectly. The flow transmitter is configured for 0-5000 mmWC and output is square rooted.
Orifice sizing is done for operating temperature.

AHEC Generating Process Animated
It will use the same hydroelectric generating equipment used in China’s Three Gorge Dam. When validated, AHEC’s generating process will store water in two large reservoirs then converts that stored energy into electricity by using the gravity and force of water flowing through hydraulic turbines connected to generators. The water is returned to the reservoir for reuse.
AHEC’s generating process plans to use existing proven hydroelectric generating technology, combined with a solar power rechargeable battery storage system to generate hydroelectricity. To compensate for the Laws Of Thermodynamics, organic solar carbon cells will be including on building windows design that connects to a series of rechargeable Lithium Iron Phosphate Batteries. The batteries would operate 10 Industrial Water Pumps at the bottom of the process and 10 Industrial Vacuum Pumps at the top of the process. Our process uses a closed-loop system that includes two large water reservoirs at the top of the process. The Main Reservoir will be larger than the second Smaller Reservoir, but of equal heights. The water will flow from the Main Reservoir into the Second Smaller Reservoir and then down to the Penstocks to the 40 Francis Turbine Generators. The difference in the water’s height between the main and second reservoir will be used to create a Positive Flow Charge in the Closed Looped System that will help the water return back to the Main Reservoir through the Return Penstock with the aid of Industrial Water Pumps.
Our process was designed to ensure that the Potential Difference between the two reservoirs never reaches zero, in order to maintain a continuous controlled return water flow.

China has completed the construction of the second biggest hydropower plant in the the world with 1-gigawatt (GW) combined capacity.
This was confirmed by the Country’s broadcaster CCTV on Tuesday.
The Three Gorges Dam, in China is the biggest hydroelectric dam in the world. The 2.3km-long concrete gravity dam is designed to control massive floods in the flood-prone upper sections of the Yangtze River by diverting them downstream. Equipped with 34 turbo generators, the power plant has an installed capacity of 22.5GW.
The facility according to CCTV has been connected to the national grid, emerging as the second largest hydro facility on the upstream branch of the Yangtze river.
The Baihetan hydropower plant is equipped with sixteen turbines, making it the second largest hydropower generator in China and the world, behind only the Three Gorges Project, also on the Yangtze river.
CCTV said that the power plant is estimated to generate 62.44 billion kilowatt-hour (kWh) annually, which could save about 90.45 million tons of coal a year and cut annual carbon dioxide emissions by 248.4 million tonnes.
Baihetan is one of six giant hydropower stations along the Yangtze river, China’s longest.
The Three Gorges Corporation, the project’s developer, has described the 289-metre (948.16 ft)dam and its associated infrastructure as one of the country’s biggest and most challenging engineering projects.
Construction began in 2017, with a total investment estimated at 170 billion yuan ($24.38 billion). As a major project in China’s west-east power transmission program, it will deliver electricity across the country to cities in the east.
China is pressing ahead with hydropower construction in the southwest, despite a long and punishing drought this summer that saw generation volumes plunge and forced regions to ration power consumption.


RIVERDALE, North Dakota --
As releases are increased to a targeted 46,000 cubic feet per second (cfs) from the Garrison Dam, in Riverdale, North Dakota, some flows will be transferred to the spillway beginning on Monday, June 17.
The updated 3-week forecast from the Missouri River Basin Water Management Division released today shows releases from Garrison Dam increasing to 32,000 cfs over the weekend reaching a rate of 35,000 cfs on Monday. To meet the targeted release of 35,000 cfs, crews will be opening three spillway gates.
“The release capacity of the powerhouse is just over 40,000 cfs, but some flows will be transferred to the spillway allowing us to proceed with previously scheduled maintenance and construction work at our switchyard, power plant and intake structure.” said Operations Project Manager for the Garrison Dam, Todd Lindquist.
The spillway will be used to avoid delays to previously scheduled work. Flows through the spillway will fluctuate based on when generating units are scheduled to be offline. This will result in varying flows through the spillway between approximately 3,000 and 16,000 cfs over the next two months.
Once all work in the power plant is complete and all five generators are available for use, the majority of releases will be run through the power plant to maximize power generation.
Total releases from Garrison are currently not forecast to exceed 46,000 cfs. Comparatively, releases during last year's high runoff reached 60,000 cfs in late June and continued for much of July. At the 46,000 cfs release rate, river stages in Bismarck are not expected to be above 11.4 feet.
Release no. 19-044

In order to reduce the investment cost and energy consumption of high pressure pump in Seawater Reverse Osmosis desalination project, a new type of multistage high pressure centrifugal pump with two ends of water-lubricated bearings supporting and axial suction was proposed after analyzing the structural feature of the high pressure pump. The numerical simulation method and mesh quality was improved, the pump performance was predicted and optimized. The relationship of the critical speed and logarithmic decay rate with stage was analyzed, and the relationship between the stage and efficiency of multistage pump was combined to analyze the optimal selection for the impeller stages of multistage pump. The experimental results of axial thrust were used to modify theoretical formula of axial thrust and accurately predicated the axial thrust at different operating conditions. A new balancing device with less leakage fluid, high balancing sensitivity and proper restoring force was designed to improve the reliability of axial thrust balancing device. The experimental results show that the efficiency of the new multistage high pressure centrifugal pump is 83.07% which is increased by 3.07 percents when the design flow rate is 220m3/h, and total Head is 620m. The new multistage high pressure centrifugal pump has been applied in the Chinese Zhoushan seawater desalination project, which runs with high efficiency and stability.
