Introduction to the detection cycle and common pro

Abstract: the so-called pressure gauge is a relatively sensitive component, which is applied to scientific research or industrial processes. In order to ensure its normal performance, it is necessary to regularly test the pressure gauge. How long is the test cycle of the pressure gauge? What are the common problems

common problems in pressure gauge detection

according to relevant regulations, the detection cycle of pressure gauge cannot exceed six months. After all, it is a monitoring environment, which is related to safety production machines. Therefore, it is necessary to detect regularly due to the loss of data caused by sudden power failure and forgotten storage. Of course, you can also test it every three months. If you find a problem, it needs to be solved and repaired in time. Because after a long time of pressure and use, the movement of the pressure gauge will be worn and deformed, causing various faults or errors of the pressure gauge. In order to ensure its accuracy, it is necessary to detect it regularly. The impact testing machine of weiji'nan experimental machine factory is divided into manual ● electrical system: dynamic pendulum impact testing machine

the following three problems often occur in the process of using the pressure gauge

abnormal pressure measuring system of pressure gauge; In case of this problem, the valve under the pressure gauge should be turned down

the meter pointer cannot return to zero. In case of this failure, it is necessary to install an impact device on the movement of the pressure gauge, which is the limit block. In this way, even if the pressure measuring system is greatly impacted at a certain moment, the fan-shaped and cylindrical gears of the machine will not easily trip. At the same time, the installation of the limit block can also solve the problem that the pointer of the pressure gauge does not return to zero

after the use of pressure gauge force sector gear, the wear phenomenon is more serious. In fact, the solution to this fault is particularly simple. It only needs to increase the width of the sector gear, because when its contact surface increases, it can withstand long-term wear and tear, thus greatly extending its service life

in the process of using the pressure gauge, in addition to regular detection, it also needs to be cleaned regularly. When the pressure gauge is used for a period of time, if it is not cleaned inside, the wear of all parts will further increase, which will affect its normal use. In serious cases, the pressure gauge will be scrapped

the above content is the summary of the problems and solutions of the pressure gauge. If you want to prolong the service life of the pressure gauge, if you want to avoid failure, you may as well test it according to the pressure gauge detection cycle just mentioned

the so-called pressure gauge is a relatively sensitive element, which is used in scientific research or industrial processes. In order to ensure its normal performance, it is necessary to detect it. How long is the test cycle of the pressure gauge? What are the common problems? Now let's have a detailed look
