Abstract

The invention discloses a self-sucking blocking-free sewage pump. The sewage pump comprises an inlet connecting pipe, an outlet connecting pipe, a bent pipe, a pump body, an impeller and a pump shaft, wherein an outlet of the inlet connecting pipe is connected with an inlet of the bent pipe, an outlet of the bent pipe is connected with the pump body, the impeller is connected with one end of the pump shaft, and a mechanical seal is arranged between the pump shaft and the pump body; a liquid storing cavity and a working cavity are formed in the pump body, a water inlet valve is arranged at the top end of the liquid storing cavity, a gas-liquid separating pipe is arranged on one side, close to the outlet connecting pipe, of the outer wall of the pump body, and the gas-liquid separating pipe is communicated with the working cavity of the pump body. By the adoption of the technical scheme, the self-sucking blocking-free sewage pump is compact in overall structure, small in size and noise, remarkable in energy-saving effect and convenient to overhaul, the self-sucking sewage pump can work once in water, and engineering cost is greatly reduced.

Description

technical field [0001] The invention relates to a sewage pump, in particular to a self-priming non-clogging sewage pump. Background technique [0002] Due to its compact structure, small footprint and good sewage discharge effect, the sewage pump is widely used in municipal sewage projects, river pond breeding, light industry, paper making, textile, food, chemical industry, electrical industry, fiber, electrical industry, fiber, slurry It is an ideal sewage pump for chemical media such as mixed suspension. Compared with general horizontal pumps or vertical sewage pumps, due to the coaxiality of the pump and motor, the shaft is short and the weight of the rotating parts is light, so the load (radial) on the bearings is relatively small, and the service life is longer than that of general pumps. Much more, there is no problem of cavitation damage and water diversion. Small vibration and noise, low motor temperature rise, no pollution to the environment. However, the curre...
