1.Installed valve at the end of suction pipe of Self-suction sewage pump .
Suction bottom valve is actually a kind of check valve, which ensures that water can only enter the suction pipe 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 due to suction bottom The role of the valve, the suction pipe will not flow into the pool of water, so that the suction pipe has been filled with water to ensure that the pump can automatically and quickly start. The reliability of this method of water absorption by the impact of the quality of the end of the valve, for example, closed lax, water leakage, the water will slowly sink into the pool, a long time, there is no water suction pipe, causing the pump starts still Need artificial irrigation.
2.Self-suction sewage pump to reduce the inlet pipe bend, drop height and horizontal distance.
3.Self-priming pump set suction pump before the pump.
This approach requires a suction pipe on the pump suction pipe, the first run before the tank, the tank should be filled with artificial water, the first stop, because the intake pipe suction tube height above the surface height of the pipe, despite the The water level inside the tank is lower than the height of the water surface of the tank, the water inside the tank will not turn back into the pool, so the water canister can store a certain water, and because of the height of the water pipe Below the tube surface height, it can ensure that the pump suction tube filled with water, after the pump and then run, the water tank was pumped away, negative pressure tank, the pool of water under the effect of atmospheric pressure added to the Suction tank inside, through the sink tank inside.
4.Self-suction sewage pump in the pump suction pipe set vacuum pump, pump start, the vacuum pump first start, so that the pump suction tube filled with water first, 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.
