Large pumping station siphon flow cut-off device application of rotary vane vacuum pump -

with the speeding up of urbanization in our country, flood disaster and deterioration of water environment problems are also increasing. In order to better deal with these problems, the need to build a large number of large pumping stations. Outflow channels as low-lift pumping station is an important part of, if the outflow channel flow pattern is not good, will lower the efficiency of the pump device, even threatening the safety of pumping station operation. Siphon outlet using siphon principle of river closure method is simple and reliable, but the project investment is large, the section shape is complex, improper design size easy to cause the vibration etc. Bad phenomenon. Siphon is widely used in large low-lift pumping station water channel in our country. Therefore, the research and optimization of rotary vane vacuum pump application in pump station siphon outlet channel is of important theoretical significance and practical value.

siphon flow channel closure is one of the river closure device of large pumping stations are commonly used at home and abroad. The globe model is simple and reliable.

rotary-vane vacuum pump in pumping station of siphon outlet application is how to operate?

when stop, as long as the vacuum breaker valve is opened, the timely siphon will be destroyed. However, due to the high startup lift and siphon outlet unit to make the transition to normal operation for a long time, will often vibration pump unit. To lower the head start, to reduce the duration of the unstable condition of pump startup, rapidly developed a full pipe flow siphon outlet, vacuum pump is usually in the unit before the start, siphon outlet channel of the air inhaled, achieve e. after start the pump in vacuum. In addition, when the water pump turbine condition ( Power generation conditions) When run, you must use the rotary vane pump, the air in the water channel that water flows through a hump, make the pump reverse. Therefore, rotary vane vacuum pump is one of the siphon outlet port to cut off the permanent equipment, its capacity to choose and the main water pump before the start of siphon outlet port of the size of the space.

rotary-vane vacuum pump are compared with domestic similar product advantages:

1. Easy to use, easy to install and maintain;

2。 Rotary vane vacuum pump is equipped with pneumatic valve, can remove a small amount of water vapor;

3。 Rotary vane vacuum pump extreme high vacuum;

4。 Built-in force feed, plenty of lubrication, reliable performance;

5。 Equipped with automatic protection oil return double insurance device;

6。 When the inlet pressure in a 1. 33 x 10 pa, still can run continuously;

7。 Don't spill, no injection, no pollution environment.

this project adopts the siphon pump station exit, not only can reduce the loss of water flow, reduce energy consumption, and easy to maintain, lower maintenance cost, convenience of management, with high safety factor, etc. Therefore, our country many water pump station used in the process of construction of the siphon solution out of the channel. In the practical engineering, it is necessary and rotary vane vacuum pump systems. The present invention has a vacuum pump pumping speed is fast, convenient management and the advantages of less investment. Has great practical value and should be promoted.
