AI Technical Summary

Technical Problem

In the existing pressure gauge testing process, the threaded connection method causes operational difficulties, prolongs the testing time, and may cause structural wear, affecting the testing results.

Method used

Two second electric push rods and clamping block components are used to tilt and clamp the pressure gauge to be tested. Pressure calibration is achieved by combining the lifting plate and the first electric push rod. The clamping block components are adjustable to accommodate pressure gauges of different specifications. The clamping device is equipped with a sealing ring and a protective cover to ensure stability and safety.

Benefits of technology

It enables stable installation and removal of pressure gauges, shortens testing time, improves testing efficiency, expands the applicability of the device, and ensures sealing and safety.
