Adjusting pool water booster china slurry pump station and improved deployment

      For the mountain city , because of the terrain elevation differences between the high lift china slurry pumps , china slurry pump selection should note the following in mind: When selecting china slurry pumps, energy saving should be considered when a larger quantity and pressure changes , the speed can be set , replace the impeller blade angle adjustment measures ; when using partitioning partial pressure of water , the china slurry pump should be selected several groups of different pressure zones were water , reduce energy consumption.

When the terrain elevation exceeds 20m, the china slurry pump total head is too large, the pipe flow velocity is too large, too long pipes and terrain changes large and china slurry pumping stations in the valve closes too fast and so prone to stop china slurry pumping water hammer accidents caused / 0 running water , without water, submerged china slurry pumping stations, equipment damage. china slurry pump outlet should be located slow closing valves and water hammer eliminator or canceled check valve to prevent damage due to water hammer caused by china slurry pumps and piping leakage . Regulating structures identified in the pipe network design, the pipe diameter is determined by the highest traffic, and one day the highest traffic is very short, thus causing power efficiency with a water capacity of the pipe network and the china slurry pump is not high, but simply to reduce traffic would lift increases, resulting in increased pressure in the pipe , causing a waste of energy consumption increases and the drain .

For the above, taking frequency control water supply china slurry pump partitions can also be set to adjust the structure ( high pool , water towers , regulating pond , etc. ) . This also allows more uniform water supply china slurry pumping stations , water pipes and mains to reduce the pipe through , and improve the reliability of water supply pipe network . When the coefficient of variation of the water pipe network Kh> 1.5 , set about adjusting the structure can be saving more than 30% , while Kh < 1.1 , you do not adjust the structures set up . Adjust the position and size of structures in the pipe network settings and select the necessity to adjust the structure and volume , quantity, location should be determined by economic and technical comparison , select the china slurry pumping stations, pipelines , adjust cost structures of most provincial programs .

Adjust the structure to determine the location should consider the following factors: regulation structures should be located at the highest point of the water supply area , as far as possible Heights pool ; regulation structures should be located near large water users as well as users require a higher pressure ; regulating structures due may be placed in the water district ; regulation structures should be adjusted with the water supply zone structures terrain slope i1 and i2 highest water into the hydraulic gradient control points may be, when i1/i2 < 1:00 , placed in the highest point ; when i1/i2> 1:00 , placed in water district location.

Adjust the structure to determine the capacity to adjust capacity and a day in and out to adjust the structure of the flow rate. When the pipe is only a regulatory structures may change in the amount of water and water is obtained , it should consider the impact of changes in the water level of the pool china slurry pump , adjusting structure to adjust capacity to the following formula to estimate : WT = (1-A) Q (d1 + d2) 100 (7) where A is the adjustment factor to consider centrifugal itself , reflecting the decrease in lift or head is increased to reduce the flow rate increases the flow rate characteristic ; Q is a design flow rate (m3 / d); D1, d2 is the maximum ordinate the cumulative water supply line and china slurry pumping station line difference to the % Q meter .

Calculate the maximum daily water into and out of each hour to adjust structures traffic flow into and out of the cumulative flow , i was out of adjustment during the first hours of the structure of water vWi, all hours of continuous structures cumulative adjustment to adjust the volume vWi. Coupled with fire water can structures have to adjust the volume . Adjust the height of the structure can be freely Water District control point requirements to determine the water pressure . As the tree mountain pipeline network more, the flow control between the various parts of the pipe network is poor ability to decrease the reliability of the water supply , and energy waste. Therefore, we should make full use of the pool , such as adjusting the level of the structure ‘s ability to regulate flow and pressure to improve the network ‘s ability to regulate itself , and use the terrain to the poor rely on gravity water distribution pipe network in order to save energy .

Conclusion For the mountain of water , because two china slurry pumping stations exports to the most negative point ground height difference , the general district water supply and set the pressure regulating stations and structures . In the middle of two china slurry pumping stations and booster china slurry pump station configuration , classification should be based on the actual situation and the pipe network diagrams , through different combinations of / 0 is equivalent to comparing the economic china slurry pump to select china slurry pumps. Adjust the position of the structure should be determined according to the location and terrain within the pipe network china slurry pumping stations and water ; adjust the volume by the formula WT = (1-A) Q (d1 + d2) 100 OK.
