A long-life high-tight water pump and its assembly method

Abstract

A long-life high-sealed water pump and its assembly method, relating to the technical field of high-sealed water pump assembly; pump body support, motor support, motor, shaft coupling, lead screw, commutator, piston and cylinder body; pump body support and motor support Docking; the motor is fixedly installed on the motor bracket; the coupling is set in the motor bracket; the screw is coaxially set with the output shaft of the motor; the axial end of the screw extends into the motor bracket, and is connected to the output shaft of the motor through the coupling Docking; the piston is docked with the other axial end of the lead screw through the commutator; the cylinder is set on the outer wall of the piston; the motor drives the lead screw to rotate through the coupling; the commutator converts the rotation of the lead screw into the axial direction of the piston Translational movement; the invention solves the problems of high-sealed water pump piston parts stuck in motion, large radial runout, short service life of the water pump, and excessive seal leakage rate, etc., realizes digital detection of the assembly process, timely checks the performance problems of the water pump, and improves production efficiency. Shorten the development cycle.

Description

technical field [0001] The invention relates to the technical field of assembly of a high-tight water pump, in particular to a long-life high-tight water pump and an assembly method thereof. Background technique [0002] The high-seal water pump is an important equipment of the environmental control and life protection system of the space test module, and its performance affects the life safety of astronauts and the success or failure of the space test. The water pump is a general-purpose component for fluid transmission. This kind of high-seal and long-life water pump can be used for subsequent space missions such as deep space exploration and manned moon landing, and can be applied to important liquid transmission equipment on the ground. It has a good application prospect. and use value. [0003] A water pump is a mechanical device that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to incr...
