Problems solved by technology

Since the motor casing is a casting, in terms of process and strength, there are casting defects such as thicker wall thickness, easy to produce pores and sand inclusions
Therefore, the old sewage pump has defects such as complex structure, heavy weight, slow heat dissipation, easy blockage, poor sealing, rough and black outer surface, etc.

Abstract

The no-blocking dredge pump includes a pump body, an impeller, a motor, a sealed oil chamber and a mechanical seal. The impeller is one double flow passage structure set inside the pump body; the motor includes stainless steel casing, rotor, shaft, flange type upper bearing seat on the casing and lower bearing seat inside the casing. The upper bearing seat and the lower bearing seat support the rotating rotor and shaft; the sealed oil chamber is constituted with a gland, the casing and the lower bearing seat; and the casing has lower end connected to the pump body. Compared with available technology, the present invention has the advantages of less blocking, reliable sealing, high efficiency high running smoothness and reliability.

Description

technical field [0001] The invention relates to a sewage pump, in particular to a non-blocking sewage pump. Background technique [0002] With the rapid development of urban construction and environmental protection, sewage pumps are used more and more widely, whether it is the sewage discharge system of enterprises, institutions, houses, hospitals, hotels, or subways, basements, civil air defense systems, municipal engineering, construction sites, etc. Sewage pumps are required. The old-fashioned sewage pumps currently on the market are cast iron motor casings, with a bearing seat on the upper end and an oil chamber on the lower end. The oil chamber and the motor casing are two separate pieces. Since the motor casing is a casting, in terms of process and strength, there are casting defects such as thick wall thickness, easy to produce pores and sand inclusions. Therefore, the old-fashioned sewage pump has defects such as complex structure, heavy weight, slow heat dissipat...
