How to prevent rusting and scaling of rotary joints?
As a component frequently used in the industrial production process, the rotary joint is frequently used in mechanical technology equipment. In order to maintain its excellent performance, it is very important to carry out related daily maintenance and cleaning. Ensure that it does not rust and scale.
1. Keep the inside of the rotary joint drum and the pipe clean. If it is a new device, a filter needs to be added to avoid abnormal wear caused by foreign objects on the rotary joint.
2. If the machine is not used for a long time, it will cause scale and rust inside. If it is used again, it will get stuck or fall.
3. It is necessary to regularly inject oil with an oil injection device to ensure the reliability of the operation of the rotary joint bearing.
4. The rotary joint of the circulating heat medium should be heated gradually to avoid the damage to the equipment due to sudden temperature changes.
5. Check the wear and thickness changes of the sealing surface of the rotary joint; observe the friction marks on the sealing surface to see if there are three discontinuities or scratches. If conditions permit, please replace it immediately.
