Maintenance of Pressure Gauge

1. After a period of use and pressure, some deformation and wear will inevitably occur in the mandrel of the pressure gauge, and various errors and faults will occur in the pressure gauge. In order to ensure its original accuracy without distortion of value transmission, it should be replaced in time to ensure that the instructions are correct, safe and reliable.

2. Pressure gauges should be cleaned regularly. Because the pressure gauge interior is not clean, it will increase the wear and tear of various parts, thus affecting its normal work, serious pressure gauge failure, scrap.

3. According to JJG52-2013, the verification period of the pressure gauge installed in the pressure measuring part generally does not exceed half a year. For pressure gauges related to production safety and environmental monitoring, the verification period must be less than half a year in accordance with the verification rules; if the working conditions are bad, the verification period must be shorter.

4. If the medium in the pressure measuring part fluctuates greatly, is frequently used, requires high accuracy, and requires stricter safety factors, the verification period may be appropriately shortened according to the specific conditions.
