The pressure gauge should be regularly checked and maintained.
1. After a period of use and pressure, the pressure gauge movement will inevitably undergo some deformation and wear, and the pressure gauge will produce various errors and failures. In order to ensure its original accuracy without distorting the value transmission, it should be replaced in time to ensure that the instructions are correct, safe and reliable.
2. The pressure gauge should be cleaned regularly. Because the inside of the pressure gauge is not clean, it will increase the wear of various parts, which will affect its normal work, and seriously cause the pressure gauge to fail and be scrapped.
3. According to the regulations of JJG52-1999 for the pressure gauge installed at the pressure measuring part, its calibration period generally does not exceed half a year.
