| Talking about how to do well the maintenance and inspection of industrial pressure gauges |
In order to keep the pressure gauge sensitive and accurate, in addition to reasonable selection and proper installation, the maintenance and inspection of the pressure gauge should be strengthened during the operation of the boiler and pressure vessel. The operator should do the following work to maintain the pressure gauge: ( 1) The pressure gauge should be kept clean, the glass on the dial should be bright and clear, so that the pressure indicated by the pointer in the dial can be clearly seen. The pressure gauge of the dial glass or the dial scale is unclear should be stopped. Â ( 2 ) The connecting pipe of the pressure gauge should be periodically purged to avoid blockage. In particular, pressure gauge connecting pipes for gases with more oil or other viscous substances should be washed frequently. Â ( 3 ) Always check whether the rotation and fluctuation of the pointer of the pressure gauge are normal, and check whether the cock on the connecting pipe is in the fully open position. Â ( 4 ) The pressure gauge must be regularly verified and verified at least once a year by a qualified unit of measurement. After verification, you should fill in the verification record and verification certificate and add a seal. Pressure gauges that have exceeded the inspection period should be discontinued. During the normal operation of the boiler and pressure vessel, if the pressure gauge is found to be abnormal or there are other suspicious signs, the calibration should be checked immediately .
