Self-priming sewage pump to improve self-priming capacity of the four methods
Self-priming sewage pump can be widely used in municipal sewage works, river pond farming, light industry, paper, textile, food, chemicals, electricity, fiber, slurry and mixed suspension and other chemical media the most ideal impurity Pump, then in the course of how to improve its self-priming capacity? Xiaobian will introduce to you to improve self-priming sewage pump self-priming ability. Self-priming sewage pump to improve self-priming capacity of the first four methods: self-priming sewage pump suction pipe at the end of the installation of suction 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 due to suction bottom The role of the valve, the suction pipe water 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 reliability of this way of absorbing water is affected by the quality of the suction bottom valve. For example, the water in the suction pipe slowly flows into the pool due to the lax shut-off and water leakage, and there is no water in the suction pipe. As a result, Need artificial irrigation. The second: self-priming sewage pump to reduce the water pipe bend, drop height and horizontal distance. The third: self-priming sewage pump set before the pump. 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 water in the tank should be manually filled with water. After the first operation is stopped, because the height of the water inlet pipe of the water suction tank is higher than the water level in the pipe, Therefore, the water tank can store a certain amount of water, and because of the suction tank outlet pipe (ie, the suction pipe of the water pump), the height of the water tank Below the surface of the water tube, it can ensure that the pump suction pipe full of water, after the pump and then run, the water tank was pumped water pump, tank negative pressure, the pool of water under the action of atmospheric pressure added to Suction tank, through the sump tank inside. Fourth: self-priming sewage pump set in the pump suction pipe vacuum pump, pump start before the vacuum pump to start, so that the 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.
