A low-noise water supply pump assembly method

Abstract

The invention provides an assembly method of a low-noise water supply pump, including the precision decomposition process design of the shaft system; the rough positioning assembly of the motor bracket and the support; the coaxiality measurement of the motor bracket and the support hole; Hole coaxiality repair; transmission shaft, bearing and bearing support seat assembly; transmission shaft, bearing forming shaft no-load accuracy test; cylinder, piston, transmission shaft assembly and accuracy test after assembly; shaft noise detection without motor and debugging; combined assembly of motor and motor pad; combined assembly of coupling and coupling spacer. The assembly method provided by the present invention solves the problem that the motor vibration reduction assembly control of the low-noise water supply pump in the space is not quantified, and resonance is easily generated, and the coaxiality of the shaft assembly is not high, which may easily lead to shaft rotation friction noise, noise and performance measurement process. Unrefined control leads to problems such as excessive noise, which improves the performance and life of the water supply pump and ensures long-term operation safety.

Description

A low-noise water supply pump assembly method technical field [0001] The invention belongs to the technical field of mechanical assembly, in particular to a method for assembling a low-noise space water supply pump. Background technique The space low-noise water supply pump is an important equipment of the space station test support system, and its performance affects the success of the space test. failure and the safety of the astronauts' lives. The water supply pump is a general part of fluid transmission, this kind of low noise and long life water supply pump can It is used for subsequent deep space exploration such as manned moon landing, Mars research and other space missions, and can also be applied to important fluid transmission on the ground. on the input device. The water supply pump is a mechanical device that transports liquid or pressurizes the liquid, which combines the mechanical energy of the prime mover or other external energy. The amount of liqu...
