In actual production and life, we can always see the shadow of the pressure gauge
, but the pressure gauge is ignored or illegally used, which brings hidden dangers to safety:
Hidden danger 1: Because the installation configuration is not standardized, the current specification has clear requirements for the configuration, installation, use, maintenance, inspection, etc. of the pressure gauge
. However, in the actual installation, in order to reduce the monitoring of secondary parts or double meters It is necessary to set only a few numbers, and the situation of arbitrarily changing the regulations is prominent.
Hidden danger 2: Because the maintenance is not paid attention to during normal use, there is no regular inspection and cleaning during use, and no usage records are made.
Hidden danger 3: Because the inspection and verification work has not been implemented well, the verification period of the general pressure gauge is half a year, which is to ensure the reliable technical performance of the pressure gauge and the accurate transmission of the value. Because some users do not have a good understanding of the safety of the pressure gauge and do not apply for verification in advance, the phenomenon of using it beyond the verification period is very serious.
