Submersible pump has a certain degree of self-priming ability, then how should we improve its capacity?
First, the submersible pump set vacuum pump in the pump suction pipe , before submersible pump start, the vacuum pump start first, so that the pump suction pipe first filled with water to ensure that the pump automatically and quickly start. This method of water needs to have a sound automatic control system to ensure the normal work.
Second, this is simple relative to the others: no clogging submersible pumps to reduce the water pipe bend, drop height and horizontal interval.
Third, this approach requires a suction pipe in the pump set up a suction pump, before the first running should be filled with artificial water, the first stop after the operation, due to the height of the intake pipe suction tube height above the water surface , Even though the water level inside the tank is lower than the height of the water inside the tank, the water inside the tank will not flow back.
The last, install suction valve at the end of the submersible pump suction pipe. Siphon valve is actually a kind of check valve, which ensures that the water flow into the suction pipe only from the pool and can not be back, so if the suction pipe filled with water, although the water pump axis elevation above the pool water level, but because of the suction valve, the water will not sink into the pool, so that the suction pipe has been covered with water, to ensure the pump automatically and quickly start.
