Seal water supply cooling water pump is mainly backwater

Concentrator water booster pump station seal water supply whole plant, with a total water volume 180 m3 / h, while the tank volume adjustment only sm,. Seal water supply cooling water pump is mainly backwater, its  Instrument valve manifolds  of water changes, and more difficult to regulate big water tank, in order to ensure the production of water, tap water fill pipe mill will be open to the maximum, so that there is al Valve manifolds  tank, so the total amount of water tank is much larger than the amount of water tank, inevitably resulting in a great waste. To solve the problem of water wastage, the mill had tried using conventional float valve, but must be 100 pipes with a diameter of 600mm, float, its buoyancy tank water with the ups and downs vary widely, quickly causing valve rod damage, the effect is not ideal.
