What are the problems with the pressure meter?What are the good solutions to these problems in the pressure gauge?
Summarize the common faults and causes the pressure gauge, in the operation of only the exchange, because of different brands and types of pressure gauges were different. Personal recommendation if there is a problem of replacement or return to the supplier, procurement of new products, and send check calibration analysis as follows:A pressure gauge without indication. Reason: 1, pressure pipe on the cut off valve does not open; 2, pipe plug; 3, spring tube joint too much dirt siltation and plug; 4, spring tube cracking; 5, the center gear and fan tooth wear too much, and is not engaged.Two, pointer shaking large. Reasons: 1, the pressure of the medium to be tested; 2, pressure gauge installation position of vibration
As everyone knows the main parts are made by pressure gauge, Bourdon tube, joint movement, the working principle of instruments is deformed by a spring pipe core (gear fan gear and drives the pointer in the dial Center) version of the show on the measured medium pressure, pressure gauge welding mainly lead zinc silver welding, argon welding. Arc welding, special welding and so on, the instrument clarinet is 100 thousand times the normal working pressure gauge the problems in the process of using zhongchanghui,1. instrument pointer because the measured medium instantaneous pulse increases, the pointer to the file below,2. instrument pointer, after the pipeline or equipment is unloaded, it will not be zero,3. additionally, the instrument fan teeth will wear out after working for a period of time,The movement of the instrument is the heart part of the pressure gauge. More than 80% of the instrument damage is caused by the damage of the movement, and the instrument can not be used. Now, I solve the problem of instrument jump by adding the spacing nail between the existing movement,4. plus isolation chip to solve the problem of instrument not return to zero5., from the fan type tooth widening, to solve the instrument contact surface, wear resistance, in order to achieve service life extension function
