Shock resistant pressure gauge: What should I do if there is oil leakage?

1. The shock resistant pressure gauges produced by general pressure gauge units use screws to fix the instrument connector on the outside of the instrument case. Three screws are three leakage points. We fix the instrument connector inside the instrument case to solve the problem of oil leakage from the instrument screws. There is also the instrument cover. Our factory's instrument cover adopts two sealing rings. After removing the cover ring, the instrument will still not leak oil unless the instrument cover is damaged.

2. Our company's shock resistant pressure gauge is filled with 500 grade silicone oil inside the case. The characteristics of 500 grade silicone oil are that it is not easily deteriorated when in contact with air for a long time at 150 ℃, and its oxidation reaction is also slow when in contact with oxygen and chlorine at 200 ℃. It can be used at a temperature of up to 200 ℃, with a pour point of -5 ℃ and high viscosity. It has excellent chemical stability and electrical insulation performance, as well as moisture and water resistance.

3. Most other units choose glycerin or transformer oil mainly due to price factors. One kilogram of silicone oil costs 55 yuan, while one kilogram of glycerin and transformer oil only costs more than 10 yuan. A shock resistant surface 100 meter meter requires 0.5 kilograms, which increases the cost of using silicone oil. However, the chemical stability is good, while glycerin or transformer oil has poor chemical stability. Therefore, all of our shock resistant pressure gauges are filled with silicone oil and fluorine oil is optional.
