Why seismic pressure gauge will leak?

Seismic pressure gauge, also called oil filled pressure gauge, mainly used for the work environment with vibration, in our actual use are sometimes found in the process of oil leakage phenomenon. Today we will explain why seismic pressure gauge will leak? We as the manufacturer, of course, the spill is don't want to happen, but sometimes customers say oil leakage occurs. To figure out this problem, we also did a lot of testing, and finally, we summarized why seismic pressure gauge will spill three reasons. 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. Know the reason, we also gave an update the related process and improve, so that we can provide more high quality products.
