The pressure gauge sometimes has abnormal tapping displacement that is too large, the pointer of the pressure gauge is off zero or the pointer runs irregularly. When the pressure gauge is repaired, it is found that it is caused by the loosening of the pre

The pressure gauge movement is the main work object in the pressure gauge maintenance. It is the source of the pressure gauge failure and error. The maintenance personnel should have a full understanding of him to successfully complete the work tasks in

Compared with the normal adjustment of the pressure gauge of the normal movement, the adjustment method of the pressure gauge of the reverse movement has the following 3 points to be paid attention to:

Analyzing the reasons for the disorder of the upstream thread of the pressure gauge movement may have the following three aspects:

The shock-resistant pressure gauge is operated for three months to perform a primary maintenance:

Vibration-resistant pressure gauges can be seen everywhere in the petroleum, chemical and other industrial sectors, and they are indispensable in production and life. But in use, its measurement accuracy sometimes decreases, so what causes it? here we com
