How To Improve The Ability Of Self-Priming Pump?

Install a suction foot valve at the end of the suction pipe of the self-priming sewage pump. Suction foot valve is actually a check valve, which ensures that the water flow can only enter the suction pipe from the pool and can not flow backwards, so if the suction pipe is full of water, although the pump axis elevation is higher than the pool's working level, but due to the role of the suction bottom valve, the suction pipe will not flow into the pool, so that the suction pipe has always been full of water to ensure that the pump can be automatically and quickly start. The reliability of this suction by the quality of the suction valve, for example, the closure is not tight, leakage, the water in the suction pipe will slowly flow into the pool, a long time, the suction pipe will not have water, resulting in the start of the pump still need to manually fill the water.
Reduce the inlet pipe bends, drop heights and horizontal distance for the self-priming sewage pump.
Set up a suction tank before the pump. This way needs to set up a suction tank on the suction pipe of the water pump, the water pump in the first run before, the tank should be filled with water manually, after the first run stops, because the height of the inlet pipe of the suction tank is higher than water surface in the pipe, even though the height of the water surface in the pool is lower than water surface in the tank, the water in the tank won't flow backward and enter into the pool, so that the suction tank can store a certain amount of water, and because the discharge pipe of the water suction tank (that is, the Water pump suction pipe) height is lower than the water surface in the pipe, so it can ensure that the suction pipe of the pump is full of water, and later when the pump is running again, the water in the tank is pumped away, the tank appears to be a negative pressure, the water in the pool is supplemented to the suction tank under the action of atmospheric pressure.
Self-priming sewage pump in the water suction pipe set a vacuum pump, the vacuum pump first start than water pump, so that the suction pipe of the water pump is filled with water to ensure that the water pump automatically and quickly start. This suction method requires a perfect automatic control system to ensure normal operation.
