Abstract

The invention belongs to the technical field of water pumps, and particularly relates to a low-liquid-level suction sewage pump which comprises a motor, an impeller, a shell, an electric push rod, a movable cover and supporting legs. According to the sewage treatment device disclosed by the invention, the electric push rod is controlled to work through the controller, so that the movable cover moves downwards, the distance between the movable cover and the bottom of the sewage pool is reduced, and the bottom surface of the movable cover is lower than the liquid level; the negative pressure generated by the rotation of the impeller in the shell acts on the sewage between the movable cover and the pool bottom, so that the sewage enters the shell through the space between the movable cover and the pool bottom, the low-liquid-level sewage is sucked, and the sewage treatment is more thorough; and meanwhile, the movable cover moves upwards during initial water pumping, so that the sewage pump can pump water at a high speed, and the water pumping efficiency of the sewage pump is guaranteed while low-liquid-level water pumping is compatible.

Description

technical field [0001] The invention belongs to the technical field of water pumps, in particular to a low-level suction sewage pump. Background technique [0002] Sewage pumps are used for sewage discharge. Sewage will be generated in home life, agricultural production, industrial production, etc. Before sewage treatment, we often need to collect sewage for centralized treatment, and we need to use it during the collection process. Sewage pump; in the selection of sewage pump, it is necessary to decide what kind of pump to choose according to the characteristics of discharged sewage or waste water, and choose the impeller or vortex according to whether it needs to be cut; generally speaking, the discharge contains fiber Sewage with impurities needs a cutting pump, and a vortex pump is used for more solid particles. [0003] Conventional sewage pumps usually set the axis of the pump horizontally. Since the bottom of the pump is provided with a bracket, there will be a certa...
