What's the effect of the rubber plug at the top of the shock gauge? What's the effect of not cutting off?
There are 2 main functions of rubber blockage:1 prevent the transit of seismic oil leakage.2 prevent during use, due to excessive vibration proof pressure gauge and oil leakage, pollution equipment.After the rubber plug with a pressure gauge must be installed to cut the U-turn, ease pressure generated during the operation of cavity pressure in high temperature environment, vibration, seismic oil preheating after expansion will produce cavity pressure, so the use must be cut off.
General vibration proof pressure gauge is suitable for measuring the pressure of medium is a strong impulse changes or pressure impact, in the process of unloading occasions, often sudden vibrations occasions.
The role of the rubber plug at the top of the shock pressure gauge:Rubber block is to prevent silicone oil (glycerin) leakage, the pressure inside the oil is filled with silicone oil (glycerin).Rubber stoppers, sometimes called safety plugs, leak protection, such as excessive internal pressure, plug will pop up, so that the glass is not easy to break.After the pressure gauge is installed, a small hole should be inserted into the rubber to make it connect with the atmosphere, otherwise it will affect the measuring accuracy.Vibration proof pressure gauge suitable for vibration occasions. Silicone oil is resistant to low temperature, glycerol is seismic effect, can make the measurement more accurate, and prolong the service life.The effect of no cuts: high pressure gauges are no problem. It's best to cut off or poke a small hole at low pressure.
