The sleeve and shaft rotate together.On the wall of the inner holes, you can play a sealing role.Each contact surface needs to be treated hardly and polished.The sealing ring is made of chromium -containing wear -resistant cast iron, which can be used to slide by a sliding speed of less than 100m/s; if the sliding speed is within a range of 60-80m/s, it can also be made of a sealing ring with tin bronze.
Sealing ring function
1. Sealing ring ---- mainly plays a sealing airflow. Its inner circle can automatically fit the piston rod by the outer circle spring with the wear of the piston rod.2. The pump card ring (or a sealing ring) is installed on both sides of the impeller. It is used to prevent the high -pressure water used by the leaf wheel exit.3. The sealing ring can be added to the pad; the binding surface of the bearing room and the pump shell can be adjusted to add or reduce the pad, until the gap between the impeller and the sealing ring is uniform, and the rotor is flexible.The distance between the sealing rings and the impeller avoid friction.
Sealing ring specification
