Semi-submersible sewage pump for integrated pump station

Abstract

The invention provides a semi-submersible sewage pump for an integrated pump station, and belongs to the technical field of machinery. The problems that since an existing sewage pump is arranged in awater collecting tank, when a seal of a motor of the sewage pump fails, water easily enters the sewage pump, and dismounting, mounting and overhauling are inconvenient are solved. According to the semi-submersible sewage pump for the integrated pump station, the integrated pump station comprises a water tank, wherein a step is arranged at the lower end of the water tank, a plurality of water outlets with upward openings are formed in the step, and the sewage pumps are vertically and fixedly connected to the step of the water tank. The sewage pump comprises a motor and a pump body which are vertically arranged, wherein an impeller and a rotating shaft are arranged in the pump body, a water inlet end and a water outlet end are arranged on the pump body, and the water inlet end is located atthe lower end of the pump body. The sewage pump is characterized in that the motor is located at the upper end of the pump body, the water inlet end is inserted into the corresponding water outlet, and a connecting flange is arranged on the outer side wall of the pump body, can be attached to the step and is fixedly connected with the water tank. The semi-submersible sewage pump for the integratedpump station has the advantages that water is not prone to entering the motor, and disassembly, assembly and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a sewage pump, in particular to a semi-submersible sewage pump used in an integrated pumping station. Background technique [0002] With the continuous development of the economy and society and the improvement of people's living standards, people have higher and higher requirements for the quality of the environment they live in. At present, my country's housing construction is mainly divided into five categories: corporate housing, hospitals, hotels, high-rise buildings, and residential housing. Under normal circumstances, contemporary buildings are equipped with underground sewage treatment rooms. Due to the large area of ​​sewage to be treated, a sewage treatment plant was built to realize sewage treatment in a centralized manner. The centralized treatment of sewage needs to centrally transport the large area of ​​sewage discharged to the sewage treatment plant. During the se...
