Txuan® - Rotary Joints Installation And Maintenance


1. The rotary joint should avoid hitting and falling during handling and storage to avoid damaging the interface and internal parts.
2. Concentric installation ensures good operation of rotary joint.
3. When installing the rotary joint with threaded connection, attention should be paid to whether the thread direction of the inner and outer pipe corresponds to the rotation direction of the connection, and the thread direction of the inner and outer pipe should also be the same.
4. When connecting the rotary joint with the pipe, the metal hose connection must be used (our company recommends the use of disturbing metal hose). Rigid connection is forbidden.
5. The inlet and outlet of the rotary joint shall be directly connected to the hose.In order to reduce the weight of the joint, prolong the service life.
6. The inner pipe assembly, pay attention to the size and weight of the support.H8/ E7 tolerances are recommended for inner pipe and joint of internal rotary joints.
7. The support and stop of the rotary joint, the diameter of the rod should be 2mm smaller than the stop hole, so that the rotary joint can be freely adjusted and compensated.


1. The inside of the rotary joint pipe should be kept clean.Special attention should be paid to new equipment, and filters should be added if necessary to prevent wear of rotary joints.
2. If the equipment is not used for a long time, it will lead to scaling and rust inside the rotary joint. If you reuse it, please note that there will be stuck or dripping.
3. The medium of the rotary joint is hot oil or hot water should be gradually heated to avoid sudden changes in temperature.
4. Please fill oil regularly for the oiling device to ensure the reliability of rotary joint bearing.
5. Check the wear condition and thickness of the sealing surface (wear is 5-10mm); Examine the friction track of the sealing surface to see if there are discontinuous or scratches and other problems. If there are any problems, it should be replaced immediately.
