AI Technical Summary

Technical Problem

Existing motor cavity airtightness testing tools require two different sets of testing tools, and there are cases of incomplete sealing when sealing the valve port, resulting in high testing costs and inaccurate results.

Method used

A tool for testing the airtightness of a motor cavity was designed. It adopts a mounting plate structure, including a vent plug and a sealing plug. It is connected to the motor through a connecting unit and uses an airtight cover plate and an air pipe system to test the airtightness and ensure the sealing effect.

Benefits of technology

It enables quick disassembly and sealing of the motors in both the front and rear chambers, reducing testing costs and improving the accuracy of test results.
