Requirements for mechanical seals

Generally divided into two parts: liquid seal (key analysis today) and gas seal (i.e. dry gas seal, which will be professionally summarized and pushed to everyone later)

Liquid seal is a mechanical seal designed specifically for sealing liquids. In fact, the liquid film between the sealing faces is very small, equivalent to 20 inches or half a millionth of a μ m. Liquid film is beneficial for isolating and lubricating the sealing end face. When considering the pressure, temperature, and speed that seals can withstand, we understand that this is an incredible technological creation. This can only be achieved when we have high-quality liquid films.

How can it become a high-quality liquid film?

1. The liquid must be stable under operating conditions and not collapse

2. Liquids must have good lubrication properties

3. The liquid should be kept in a sealed chamber without flash evaporation or volatilization

4. The liquid should be clean and tidy, without pollutants or solid particles

5. The liquid must have a moderate viscosity
