Maintenance of rotary joints

1, should keep the rotary joint drum and pipe inside clean. Special attention should be paid to new equipment, and filters should be added if necessary to avoid abnormal wear caused by foreign bodies on rotary joints.
2, because the machine is not used for a long time will lead to scaling and rust inside the rotary joint, please pay attention to the occurrence of stuck or dripping if used again.
3, with the oil injection device, please fill the oil regularly to ensure the reliability of the rotating joint bearing operation.
4, the rotary joint of the fluid medium should gradually generate temperature to avoid rapid temperature changes.
5. Check the wear condition and thickness change of the sealing surface (generally normal wear is 5-10mm); Observe the friction track of the sealing surface to see if there are three points intermittent or scratched problems, if there are above the condition, should be replaced immediately.
6, the rotary joint should be handled lightly, strictly prohibited from impact, so as not to lose the joint component.
7. Foreign bodies are strictly prohibited from entering the rotary joint.
8, rotary joint do not idle for a long time.
