Home pump self-priming pump plays an important role in daily life, can make the pump in the high place to the low liquid level or liquid suction pump cavity through the impeller high-speed liquid thrown out to reach the delivery and The purpose of promotion of liquid. If the home self-priming pump sometimes unqualified products or long service life, decreased self-absorption capacity, we can not achieve the desired purpose, so to understand and master self-priming pump to increase and increase self-absorption capacity of the method is particularly important . How to improve the self-priming pump self-priming capability Introduced on the introduction to enhance the service life of self-priming pump to enhance self-priming capability First, the self-priming sewage pump in the pump suction pipe set up a vacuum pump before the pump starts, the vacuum pump to start, Pump suction pipe filled with water, to ensure that the pump automatically, quickly started. This kind of water absorption method needs perfect automatic control system to ensure normal work. Second, self-priming pumps reduce the water pipe bend, drop height and horizontal spacing. Third, self-priming pump set pump suction tank. 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. Fourth, self-priming sewage pump suction pipe end installed suction bottom valve. 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 how to extend the service life of home self-priming pumps and improve their self-absorption capacity, hoping to provide some help for your operation and use.
