How to make seismic pressure gauge does not leak?

Seismic pressure gauge, also called oil filled pressure gauge. Is mainly used to measure using the environment pressure. It's principle is to inject the oil inside the pressure gauge shell, because the oil cushion can have obvious impact on the earthquake, 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, extend 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. So how can make seismic pressure gauge does not leak? Actually we get the seismic pressure gauge leak reason, can effectively prevent. Adjusted seismic pressure gauge leak reason mainly has the following three 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. Thus, the main factors for seismic pressure gauge of oil spill caused in the process of production of non-standard operation. So we should regulate the employee's operation process, reduce the non-standard operations.
