In almost all industrial sectors, as long as there is a liquid and gaseous medium to be transferred between the fixture and the rotating machine, the swivel joint is a necessary connection. The rotary joint is an important sealing device for the dynamic and static transmission of fluid in the equipment, and due to the long-term operation of the equipment, the rotary joint seal will be worn, damaged and leaked. Therefore, it is particularly important to carry out the necessary routine maintenance of the rotary joint. It mainly includes lubricating the bearing, replacing the seals, and checking the tightness of the connectors. At the same time, for rotary joints with high sealing performance requirements, it is also necessary to regularly clean and detect the wear of the sealing surface, and replace the damaged seals in time.
Start with the following aspects:
1. Keep the inside of the rotary joint drum and pipeline clean. Special attention should be paid to new equipment, and filters must be added to avoid abnormal wear and tear caused by foreign objects to the rotary joints.
2. Because the machine is not used for a long time, it will cause scaling and rust inside the rotary joint, please note that if you use it again, there will be jamming or dripping.
3. If it is equipped with an oil injection device, please inject oil regularly to ensure the reliability of the operation of the rotary joint bearing.
4. The rotary joint of the fluid medium should be gradually warmed to avoid rapid temperature changes.
5. Check the wear and thickness changes of the sealing surface of the seal (generally the normal wear is 5-10mm), observe the friction trajectory of the sealing surface, and see if there are problems such as three-point intermittent or scratches.
6. The rotary joint should be handled with care, and it is strictly forbidden to be impacted, so as not to lose the joint components.
7. It is strictly forbidden for foreign objects to enter the inside of the rotary joint. The fixing and stopping device should not be loose or fall off.
8. Do not idle the rotary joint for a long time.
To sum up, the swivel joint realizes the media transfer and sealing effect between two opposite rotating parts through its structure and working principle. It plays an important role in the industrial sector, enabling machines and equipment to function properly.
