Clean water pump and water pressure adjusting method applying clean water pump

Abstract

The invention relates to a clean water pump which comprises a rack, wherein a motor is arranged on the rack, the motor comprises a motor shell, a mounting hole is formed in the side wall of the motor shell, two mutually symmetrical angular contact ball bearings are coaxially embedded in the mounting hole, the motor shell is provided with a fixing mechanism, and a positioning assembly is arranged on an output shaft of the motor; the free end of an output shaft of the motor is rotationally connected with the shell through a deep groove ball bearing and coaxially connected with an impeller. The output shaft of the motor is axially limited through the two mutually symmetrical angular contact ball bearings, so that the output shaft of the motor is not liable to axially move during rotation, and sliding friction is not liable to occur between the output shaft of the motor and the deep groove ball bearing, and therefore, the working temperature of the output shaft of the motor is not easy to exceed the allowable upper limit of the output shaft of the motor, and the service life of the output shaft of the motor is prolonged.

Description

technical field [0001] The present application relates to the field of water pumps, in particular to a clean water pump and a water pressure regulating method using the clean water pump. Background technique [0002] Clean water pumps are used to transport water and other liquids similar to water. They are commonly used in industrial clean water supply systems, urban water supply and drainage systems, and garden irrigation systems to increase water pressure. [0003] refer to figure 1 with figure 2 , the clean water pump in the related art includes a frame 1, a housing 11 and a motor 2 are installed on the frame 1, an impeller 7 is installed in rotation in the housing 11, and the output shaft of the motor 2 passes through the housing 11 and is coaxial with the impeller 7 It is fixedly connected, and the output shaft of the motor 2 is rotatably matched with the casing 11. The casing 11 is also provided with a water inlet and a water outlet. The rotation of the motor 2 driv...
