AI Technical Summary

Technical Problem

The existing pressure gauge cannot adjust the base plate for balance during testing, resulting in low testing accuracy and fatigue and low efficiency due to manual pressurization operation.

Method used

A desktop electrically controlled pneumatic pressure source was designed. The height of the four corners of the base plate is adjusted by adjusting the components to make it in a balanced state. Constant speed pressurization is carried out by electric control. The pressure is monitored by a pressure regulating valve, a shut-off valve, a pre-pressurization pump and a positive and negative pressure reversing valve.

Benefits of technology

It improves the accuracy and efficiency of testing, avoids problems such as uneven pressure application and inconvenient reading, and achieves testing results that are simple to operate, accurate and reliable in data, and have a wide range of applications.
