Do you know the cause of oil filled pressure gauge leak?

Oil filled pressure gauge is a kind of pressure gauge, refers to the internal injection pressure gauge shell oil, because oil can have obvious impact on the earthquake cushion, so that it can reduce the 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 and prolong the service life of the instrument at the same time. But there are in the process of our actual use is will find table leak phenomenon. Today let's talk about oil filled pressure gauge the reason of oil leakage. The principle of oil filled pressure gauge is mainly case inside filling the aseismic silicone oil or glycerine, the table of oil leak reason in general there are three main aspects: 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.
