Centrifugal pump and water ring vacuum pump are the power components of spraying truck. Under the joint action of centrifugal pump and water ring vacuum pump, liquid is pumped from liquid source or charging bucket and transported to the charging bucket or outside. Therefore, centrifugal pump and water ring vacuum pump are the parts that contact water or detergent most. Meanwhile, the rotating speed of centrifugal pump is up to 2000r / min, Under the combined influence of the scouring action of the washing fluid with particles and the cavitation of the fluid, it is easy to produce corrosion and various faults.
For example, due to corrosion between the pump cover and the pump body, it is easy to leak liquid or the fixed nut is rusty, which is not easy to disassemble and install. The corrosion of the inner wall of the pump body and the impeller of the centrifugal pump affects the rotation of the impeller, or the temperature is too high due to friction, and the noise of the centrifugal pump is too high; the pump shaft is corroded under the action of the detergent, and the strength is reduced, resulting in the loose fixation of the impeller; the inner wall of the pump body and the impeller of the water ring vacuum pump are loose At the same time, corrosion affects the rotation of the impeller, or the temperature is too high due to friction, and the phenomenon of excessive noise of centrifugal pump; the leakage of liquid and air at the connection part of inlet pipe and exhaust pipe between centrifugal pump and water ring pump affects the filling of water.
