First, the submersible pump in the pump suction pipe set on the vacuum pump, pump start before the start of the vacuum pump, so that the first water pump filled with water to ensure that the pump automatically and quickly start. This type of water absorption requires a sound automatic control system to ensure proper operation.
Second, relative to the following are also relatively simple: no clogging submersible pump to reduce the water pipe corners, drop height and horizontal interval.
Third, this way need to set up a suction pipe in the pump, the pump in the first run before the tank should be filled with water, the first run after the end of the water tank due to the height of the water pipe height , Although the water level in the pool below the tank surface height, the tank of water will not turn back.
The last way to install the suction end valve at the end of the suction pipe of the submersible pump. The suction valve is actually a check valve, which ensures that the water can only enter the suction pipe from the pool and can not be reversed, so if the suction pipe is filled with water, although the pump axis elevation is higher than the working water level of the pool. The role of the end of the valve, the water pipe will not flow into the pool, the suction pipe has been filled with water, to ensure that the pump can automatically and quickly start.
