AI Technical Summary
After the sealing test of existing new energy vehicle pipe joints, test media is easily left on the surface, which needs to be transferred to separate cleaning equipment for treatment, resulting in reduced production efficiency.
A device for testing the sealing performance of pipe joints in new energy vehicles is designed. It combines a booster water pump, a cleaning fluid tank, a high-pressure pipeline, and a high-pressure nozzle to achieve in-situ cleaning of the pipe joints after testing. The cleaning effect is enhanced by a motor-driven rotating ring and agitator.
This enables efficient cleaning of pipe fittings after testing, reduces process connection time, and improves the integrated efficiency of testing and cleaning.
