Assembly method of low-noise water supply pump

Abstract

The invention provides an assembly method of a low-noise water supply pump. The assembly method comprises the following steps of designing a shaft system precision decomposition process, roughly positioning and assembling a motor bracket and a support, measuring the coaxiality of the hole positions of the motor bracket and the support, repairing and matching the coaxiality of the hole positions of the motor bracket and the support, assembling a transmission shaft, a bearing and a bearing supporting seat, forming a shafting no-load precision test by the transmission shaft and the bearing, assembling a cylinder body, a piston and the transmission shaft, testing the precision after assembling, detecting and debugging the noise of a motor-free lower shaft system, combining and assembling a motor and a motor rubber mat, and combining and assembling a coupler and a coupler shock insulator. According to the assembly method, the problems that resonance is prone to being generated due to the fact that motor vibration reduction assembling control of the space low-noise water supply pump is not quantified, shaft system rotating friction noise is prone to being caused due to the fact that precision such as coaxiality is not high during shaft system assembling, the noise is out of tolerance due to the fact that noise and performance measuring process control is not refined and the like are solved, the performance and the service life of the water supply pump are improved, and long-term operation safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of mechanical assembly, and in particular relates to an assembly method of a space low-noise water supply pump. Background technique [0002] The space low-noise water supply pump is an important equipment of the space station test support system, and its performance affects the success or failure of the space test and the life safety of astronauts. The water supply pump is a common component for fluid transmission. This kind of low-noise and long-life water supply pump can be applied to subsequent deep space exploration such as manned moon landing, Mars research and other space missions, and can also be applied to important fluid transmission equipment on the ground. [0003] The water supply pump is a mechanical device that transports liquid or pressurizes the liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. The liqui...
