Problems solved by technology

[0003] There are many brands of pipeline sewage pumps on the market, but most of them have a high failure rate when they are used. The sewage is often blocked when the sewage is immersed in the pump body, which affects the speed of sewage discharge.
Most pipeline sewage pumps have poor operational safety performance, are prone to safety accidents, and have a short service life, which increases maintenance costs

Abstract

The invention discloses a pipeline blow-down pump. The pipeline blow-down pump comprises a pump body, a motor and an impeller. A water inlet is formed in one side of the pump body, a water outlet is formed in the other side of the pump body, a motor installation groove is formed in the upper portion of the pump body, the motor is arranged in the motor installation groove, the impeller is arranged at the end of the output shaft of the motor, the impeller is located in the pump body, the impeller is of a cavity structure, a bent pipe of 90 degrees is arranged in the cavity, the two ends of the bent pipe communicate with the cavity, an inner cavity, opposite to the water outlet, is formed in the pump body, the bottom end of the bent pipe communicates with the water inlet, and the top end of the bent pipe, the water outlet and the inner cavity are located on the same horizontal surface. A filtering device is arranged at the water inlet so that dirt can be conveniently stored so as to be prevented from entering the pump body, and the service life of the pipeline blow-down pump is prolonged.

Description

technical field [0001] The invention relates to the field of drainage systems, in particular to a pipeline sewage pump. Background technique [0002] The pipeline sewage pump can be used as a general pipeline pump to pressurize water for high-rise buildings, and can also transport sewage containing particles and fibers. In addition to being suitable for transporting sewage, it is also suitable for drainage pumps, filter flushing condensate circulation pumps, etc. As people pay more and more attention to sewage treatment, pipeline sewage pumps are more and more widely used in daily life. [0003] There are many brands of pipeline sewage pumps on the market, but most of them have a high failure rate when they are used. The sewage is often blocked when the sewage is immersed in the pump body, which affects the speed of sewage discharge. Most pipeline sewage pumps have poor operational safety performance, are prone to safety accidents, and have a short service life, which incre...
