Rotary Seals

Before carrying out the test of rotary seal valve, it is necessary to check the control program of the rotary valve. After the shell pressure and sealing test are completed, install the motor on the r...

The leakage rate refers to the total amount of fluid leaked through the main seal and auxiliary seal in unit time; it is an important index for evaluating the sealing performance of the fluid. The lea...

1. The influence of the seal surface state on the leakageIn order to explain completely a sealed surface, there must be five parameters: roughness, flatness, wave degree, knife mark state and disconti...

In the research in the last century, there were obvious wear and local burning phenomena on the mechanical seal friction pairs of the rotating seals in the measurement of the characteristics of the ro...

The ring type rotary seal device is mainly applied to the dynamic seal of the rotating shaft. For example, the seal between the connecting disc on the clutch and the stationary bearing seat. The steer...
