1 The first method (the simplest)

The self -absorbing sewage pump is set on the water pump water absorption pipeline. Before the pump is started, the vacuum pump is started first, so that the water pump water absorption pipe is covered with water to ensure that the pump is automatically and quickly start.

This method of water absorption requires a complete automatic control system to ensure normal work.

2 The second method (simpler)

Self -suction pumps reduce the water inlet pipeline curve, the height of the difference and the horizontal interval.

3 The third method (troubles but easy to use)

Self -suction pump sets the water absorption tank in front of the pump. In this way, a water absorption tank needs to be set on the water pump water absorption pipe. Before the first run, the pump should be filled with water artificially. After the first operation, the height of the water inlet pipe in the water absorption tank is higher than the height of the water surface in the pipe. The height of the water surface in the pool is lower than the height of the water surface in the tank, and the water in the tank will not flow backwards. Enter the pool. Therefore, a certain amount of water can be stored in the water absorption tank. Below the height of the water surface in the pipe, so it can ensure that the water absorption pipe of the water pump is covered with water. When the pump runs again, the water in the water tank is pulled away by the pump, and the inner pressure inside the tank is arranged. Add to the water absorption tank and use the water absorption tank pond.

4 The fourth method

The water absorption bottom valve is installed at the end of the water absorption pump. The water absorption bottom valve is actually a stop valve. It guarantees that the water flow can only be pipe from the pool into the water absorption pipe without flowing. Therefore, if the water absorption pipe is covered with water, although the axis of the pump is higher than the water level of the pool, it is because there is water absorption The effect of the bottom valve, the water in the water absorption pipe will not flow into the pool, which can always be covered with water in the water absorption pipe, ensuring that the pump can be automatically and quickly start.
