Two application guidelines for gas seals

There are many types of seals, and gas seals are one of them. The damping pressure should be maintained even when the mixer is shut down. This is to prevent the product (or product vapor) from penetrating into the seal. Of course, the damping air should be clean and free of oil and moisture. Gas lubricated agitated seals are much more sensitive than liquid lubricated seals. Burgmann AGS and AGSR mixer seals help users improve product quality and product purity when properly applied to the right application. Due to the low rotational speed, the aerostatic properties are of the utmost importance for the gas seal of the mixer. Therefore, the supply of damped air plays a very important role. The following factors are very important:
The pressure in the existing nitrogen pipe network is not always stable. When the line pressure is just above the required damping pressure, the pressure pulsation is much greater than the accepted effect. In some cases, optimization can be achieved by adding an accumulator and a loop one-way valve upstream of the supply system. Moreover, several seals are often installed on a supply system, and unfortunately they cannot be individually monitored and supplied. For gas seals, there are two main criteria: always keep the flow at the seal and often maintain sufficient damping pressure. Both of these guidelines should be monitored.
