Shock resistant pressure gauge: a mechanical pointer type pressure gauge with filled fluid inside the case, or a mechanical pointer (or rotary dial) type pressure gauge with filled fluid and damper inside the case.
Principle of shock resistant pressure gauge: It consists of a pressure guiding system (including joints, spring tubes, flow limiting screws, etc.), a gear transmission mechanism, a reading device (pointer and dial), and a housing (including case, cover, glass, etc.). The shell of the shock resistant pressure gauge is an airtight structure, which can effectively protect the internal components from environmental impact and contamination invasion. A shock resistant pressure gauge is an instrument that is filled with damping fluid (usually silicone oil or glycerin) inside the housing, which can resist working environment vibrations and reduce the pulsating effects of medium pressure.
For the use of shock resistant pressure gauges, different levels of maintenance are required. For both, maintenance needs to be carried out once every three months, while for secondary maintenance, it needs to be carried out once a year. The second level maintenance of the shock resistant pressure gauge requires disassembling the pressure gauge, sending it to the metrology department for verification and lead sealing. Secondly, it is necessary to disassemble and inspect the water storage bend pipe to ensure that the threads are intact. In addition, it is necessary to disassemble and inspect the three-way plug, grind the sealing surface to ensure it is tight and leak proof, and the connecting thread should also be intact and undamaged. For water storage bends, the three-way plug should be derusted and painted.
So that's all for the introduction about shock resistant pressure gauges above. I hope it can be helpful for your understanding.
