The invention relates to a sewage pump with a cutting function. The sewage pump comprises a motor shell, a box cover, a pump cover, a pump body, a motor, an impeller, a float switch and a power line. The box cover is connected to the top of the motor shell, a line outlet and an air nail are arranged on the box cover, and the power line is fixed in the line outlet in a sealing mode through a power line sealing component. The power line sealing component comprises a gland nut, a gasket and a sealing ring. Internal threads are arranged on the inner wall of the line outlet, the end of the power line penetrates through the gland nut to extend into the line outlet, and the sealing ring is arranged between the bottom of the line outlet and the end of the power line. The gasket is arranged between the end of the power line and the bottom of the gland nut, and the gland nut is screwed in the line outlet so as to fix the end of the power line in the line outlet in a pressing mode. The pump cover is fixedly connected with the bottom of the motor shell, the pump body is connected to the pump cover, a water outlet is formed in the side, where a water inlet is formed, of the bottom of the pump body, the impeller is fixedly arranged at the bottom end of a motor shaft in a sleeved mode and located in the pump body, and cutting blades are further arranged on the impeller. The sewage pump with the cutting function is good in sealing effect and stable in operation.
Description
Technical field
The present invention relates to a kind of water pump, belong to mechanical equipment technical field.
Background technique
Water pump is the machinery of carrying liquid or making liquid supercharging.Rotate liquid acting by the pump shaft impeller of prime mover, liquid energy is increased, rely on this energy that liquid is transported to appointed place.When water pump operation, impeller does high speed rotating motion in the pump housing, liquid in the pump housing is along with rotation of impeller, under the effect of centrifugal force, liquid is thrown away by impeller at water outlet, the liquid throwing away speed in pump housing explosion chamber is slack-off gradually, and after liquid is thrown out of, impeller center forms vacuum low-pressure district, liquid in liquid pool is under the atmospheric effect in the external world, in water inlet flows into water pump.Then liquid continuously drunk up and be continuously discharged from from pump outlet again like this from liquid pool.
In actual life, a lot of situations need to be carried sewage, and in sewage, contain the fibre object of solid particle and easy winding or pack, easily cause impeller and pump housing inner wall abrasion and impeller obstruction etc., can make pump efficiency reduce in long-time running.
