Do you know the pressure gauge without indicating what reason be

Pressure gauge refers to the principle of elastic element as the sensitive element, measure and instructions above environmental pressure meter, application is very common, it almost throughout all of the industrial process and research fields. In the heat pipe network, oil and gas transmission, water supply, gas supply system, vehicle maintenance shop, etc can be seen everywhere. Especially in the process of industrial process control and technology measure, due to the flexibility of mechanical pressure gauge sensor has high mechanical strength and production is convenient wait for a characteristic, make the mechanical pressure gauge is widely used. Do you know the pressure gauge without indicating what reason be? The following instrument for you to answer the reason one: tube dirt deposition in blocking the spring cleaning is recommended, with copper wire open, clear dirt; Reason two: spring tube have sand holes or cracks recommend repair welding sealing sand holes, or replace the spring tube; Reason 3: sector gear and small gear resistance is suggested to adjust the fit clearance to moderate; Reason four: two gear wear too much, not or recommend replacing two gears; Reason 5: free end connected to the connecting rod off Suggestions on loss of pin or screw; Six reasons: table gasket joint, or a load advice suitable gasket, strengthening seal. Pressure gauge use notice: 1. After a period of use with pressure, pressure gauge movement deformation and wear, hard to avoid can appear some pressure gauge can produce all kinds of errors and failures. In order to guarantee the accuracy of its original without distortion, dissemination should be replaced in a timely manner, to ensure that the correct, safe and reliable. 2. Pressure gauges need to clean them regularly. Because the interior of the pressure gauge is not clean, will increase the wear parts, thus affecting its normal work, serious can make the pressure gauge failure, scrap. 3. In the pressure on the installation of pressure gauge according to JJG52 - 1999 regulations, its verification period is generally not more than half a year. 4. Pressure parts of the medium wave, frequent use, the accuracy of the demand is higher, and more strict with safety factor, will test cycle shorten appropriately according to the specific situation.
