Description

Circulating water pump Technical Field The utility model relates to the technical field of water pumps, in particular to a circulating water pump. Background The water pump is widely applied to various liquid conveying fields, especially the fields of industry, agriculture, urban water supply, drainage, sewage treatment and the like, and has the core function of conveying liquid from one place to another place. However, in the practical use process, the conventional water pump has some performance problems and limitations, such as low water flow pushing efficiency, large energy loss, easy blockage caused by impurities, reduced pumping efficiency with the use time, and the like. These problems not only affect the operation stability of the water pump, but also increase the energy consumption and maintenance costs. Specifically, the existing water pump often has the following technical defects: in the traditional water pump, the cooperation of the slurry plate and the inner wall of the pump body often causes uneven distribution of the water flow driving force, influences the pumping efficiency, and can cause blockage or increase of resistance along with the entering of impurities. The energy efficiency is low, and the driving system of the water pump often has the problems of low transmission efficiency and large energy loss. Particularly, when the matching of the driving shaft and the pulp sheet is inaccurate, the power transmission loss is caused, so that the overall working efficiency of the water pump is reduced. During the operation of the water pump, impurities and particles in the liquid can interfere the operation of the water pump, so that the water flow is not smooth or is blocked, and the pumping effect and the service life of the equipment are affected. In view of the above, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a circulating water pump that solves the problems and improves the practical value by the above technique.
