       2. If the moving parts have abnormal sounds, it indicates that a proper amount of grease needs to be added to the rotating parts;

       3. Rubber seals will deteriorate after a period of use and need to be replaced regularly;

       4. After confirming that there is no pressure in the system, switch between positive and negative pressure. If leakage is found at the switch, the seal needs to be replaced.

       All in all, the service life of the pressure gauge calibration station lies in the user's maintenance and maintenance, and it is quite necessary to deal with small problems in a timely and effective manner. At the same time, it is necessary to pay attention to all kinds of media measured by pressure instruments working on site, especially corrosive media.
