Instructions

1. Keep the drum and pipe wall clean, pay more attention to new equipment, and add filters when necessary to avoid abnormal wear of the rotary joint caused by foreign matter.
2. When the rotary joint is found to be leaking, stop the machine in time to check the cause of the leak, and do not work at high speed to avoid abnormal damage to some parts.
3. Do not run it idling for a long time when the medium is not flowing.
4. The structure inside the rotary joint will rust due to long-term disuse of the machine. Please note that if you clean the rust before using it, it will be stuck and dripping.
5. For those with oil-filled devices, please fill them with oil regularly to ensure the reliability of the bearing operation.
6. The rotary joint that circulates hot medium should be heated gradually to avoid sudden temperature changes.

Maintenance instructions

1. When disassembling the rotary joint, pay attention to the impact of excessive temperature on the body. 2. When disassembling and opening the rotary joint, pay attention to the assembly sequence and keep the original state of the internal structural components to analyze the cause of the leak.
3. Check the wear condition and thickness change of the sealing surface (normal wear is 5-10mm); observe the friction track of the sealing surface to see if there are problems such as three-point intermittent contact or contact surface. This is an abnormal wear condition and should be repaired in time.
