Dry Gas Seals Sealed and reliable

The advantages of dry gas seal

1. Sealed and reliable, in the longer so that the Shanghai dry gas seal period will not leak or rarely leak. Clean, no dead ends, can prevent contamination of bacteria.

Second, the use of long life, the correct dry gas seal standard choice of friction load than the pressure of the dry gas seal can be used for 2 to 5 years, the longest useful to 9 years.

Third, the maintenance cycle is long, in the case of normal work, no maintenance.

The shaft or sleeve is not worn.

5. Friction power consumption less, generally about 10 to 50% of the stuffing box seal,

6. Dry gas seal on the shaft accuracy and smoothness No stuffing box requirements so strict, the rotary reactor dry gas seal shaft vibration and shaft of the shell hole deflection is not sensitive to the vibration of the shaft sensitivity.

7. Applicable to a wide range, can be used for low temperature, high temperature, high vacuum, high pressure, a variety of speed and corrosive, abrasive, flammable, explosive, toxic media seal.

1, dry gas seal the working principle

Dry gas seal is a pair of pairs of vertical relative to the axis of the relative sliding of the end surface in the FGD system dry gas seal fluid pressure and the arrangement of the elastic (or magnetic) effect stick to the swallowed together with the auxiliary seal to reach the leakage of the shaft Sealing equipment.

2, dry gas seal commonly used materials selection
