Description

technical field

[0001] The invention relates to a water seal on a mechanical seal gland. To improve the sealing effect of the water seal on the gland. Background technique

[0002] There is a water seal on the gland of the mechanical seal device, especially in the API682-62 scheme, the water seal is a very commonly used auxiliary sealing element. The water seal on the gland of the traditional mechanical seal device is to set up a labyrinth groove or throttle groove on the inner ring surface of the water seal ring to reduce the leakage of quenching water. When the pump shaft is running, a labyrinth groove and shaft Or the shaft sleeve cooperates, the shaft sleeve rotates to drive the quench liquid to rotate to generate centrifugal force, and cooperates with the resistance of the throttle ring groove to the liquid to prevent the quench liquid from leaking outward. Because there is a gap between the water seal ring and the shaft sleeve, the quench liquid can easily leak out...
