How to make the seismic pressure gauge does not leak?

Seismic pressure gauge, also called oil filled pressure gauge, in our actual use are sometimes found in the process of oil leakage phenomenon. Today let's talk about how to make the seismic pressure gauge does not leak. The principle of seismic pressure gauge is mainly case inside filling the aseismic silicone oil or glycerin, therefore, carefully deal with the problem in three aspects, seismic pressure gauge your oil leakage problem can be solved. 1. Base is the thread seal between hex and pan was not well done, there might be a virtual welding welding or not sealing gasket. 2. Cover gasket between the circle and pan, there is cause gasket askew when fastening cover ring, and did not have the effect of sealing. 3. Fill oil plug at the time of installation are not smooth or not installed in place. The working principle of seismic pressure gauge is to point to inside the pressure gauge shell injection oil, because oil can have obvious impact on the earthquake cushion, so that it can reduce volatility, external vibration for pressure measurement, the effects of reading, through to the oil filled in the table, also parts of the machine lubrication effect, extend the service life of the instrument at the same time.
