How to improve the pump self-priming ability? With this question, the next to introduce you to improve the non-clogging sewage pump has a certain self-priming capability, Methods to plug the self-priming capacity of the sewage pump. The first approach is to improve the self-priming capacity of non-clogging sewage pump The first way is the easiest way: plug the sewage pump in the pump suction pipe set up a vacuum pump before the pump starts, the vacuum pump to start, so that the pump suction pipe filled with water, to ensure that the pump Automatic, quick start. This kind of water absorption method needs perfect automatic control system to ensure normal work. The second method is also relatively simple compared to the following: Non-clogged sewage pump to reduce the water pipe bend, drop height and horizontal spacing. The third method is a little cumbersome, but it is also good to use: Non-clogged blowdown pumps Set pump suction cups. In this way, a water suction tank needs to be set on the water suction pipe of the water pump. Before the first operation of the water pump, the tank should be manually filled with water. After the first operation is stopped, since the height of the water inlet pipe of the water suction tank is higher than the water level in the pipe, The water level in the tank is lower than the water level in the tank. The water in the tank will not flow back into the water tank. Therefore, a certain amount of water can be stored in the water tank and the height of the water outlet pipe of the water tank Lower than the tube surface height, it can ensure that the pump suction pipe full of water, after the pump and then run, the water tank is pumped by the pump, the tank thrown negative pressure, water in the pool under the action of atmospheric pressure Added to the suction tank, through the sump tank inside. The last option is to install a suction-bottom valve at the end of the suction pipe without a clogged drain pump. Suction valve is actually a check valve, which ensures that water can only enter the suction pipe from the pool and can not reverse, so if the suction pipe filled with water, although the pump shaft elevation above the working level of the pool, but because there is suction 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. The above is to improve non-clogging sewage pump, in addition to these methods can also be used to improve non-clogging sewage pump life.
