The structure of a sewage pump usually includes components such as impeller, blades, pump casing, suction pipe, and outlet pipe. When the pump casing is filled with water, when the impeller rotates, the liquid undergoes high-speed rotational motion under the action of the impeller. Under the action of centrifugal force, the pressure at the outer edge of the impeller increases, and this pressure is used to direct the water pressure towards the outlet pipe. At the same time, the pressure of the liquid at the center of the impeller decreases, forming a hollow space, and water is drawn up from the pool by the suction pipe.
In addition, the design of the sewage pump also takes into account the application of an automatic control system, which achieves automatic start stop function through sensor detection and controller instructions, ensuring the timeliness and convenience of sewage discharge. Once the sewage is discharged, the lifting pump will automatically stop working and enter standby mode to save energy. This automatic control system plays a crucial role in the lifting pump equipment, further improving the control logic of the sewage lifting pump.
