To extend the lifespan of rotary joints, comprehensive maintenance and upkeep are required from multiple aspects. Here are some key measures and suggestions:
1).Avoid idling: When the rotary joint is not connected to the medium, it should be avoided from idling or running for a long time as much as possible, because long-term idling will increase wear and shorten the service life.
2).Use hoses for medium inlet and outlet: The medium inlet and outlet should be connected with hoses, such as flexible metal corrugated pipes, to avoid using steel pipes to reduce vibration and wear.
3).Avoid installing other accessories directly: It is not recommended to install valves, filters, and other accessories directly at the inlet and outlet of the medium. If installation is required, they should be added to the pipeline behind the hose.
4).Gradually heating up: For the rotating joint of the circulating heat medium, it should be gradually heated up during startup to avoid damage caused by sudden temperature changes.
1).Cleaning and maintenance:
· Surface cleaning: Regularly inspect the surface of the rotary joint to ensure that there are no dust, oil stains, or other debris, which helps dissipate heat and prevent corrosion.
· Internal cleaning: Keep the rotating joint drum and pipeline clean, especially for new equipment. If necessary, add filters to avoid abnormal wear of the rotating joint caused by foreign objects.
2).Seal inspection: Regularly check the wear and thickness changes of the sealing surface, observe whether there are any abnormalities in the friction trajectory, and replace the seal in a timely manner if there are any problems.
3).Vibration inspection: Regularly check the vibration of the rotating joint. If any abnormal vibration is found, the machine should be stopped for inspection and handling in a timely manner.
4).Fixed bolt inspection: Check if the motor foundation fixing bolts are loose. If they are loose, use a torque wrench to tighten them to the required torque.
For rotary joints with oil injection devices, regular oil injection should be carried out to ensure the reliability of bearing operation. When injecting oil, the appropriate lubricating oil and oil injection amount should be selected according to the instructions. Regular lubrication can reduce internal wear and extend service life.
If the machine is not used for a long time, the inside of the rotary joint may scale or rust. Before reuse, the rotary joint should be thoroughly cleaned and inspected to ensure that there is no jamming or dripping. At the same time, regular turning should be carried out to prevent rusting of the internal and sealing surfaces of the rotary joint.
1).Precautions during installation: The installation of the rotary joint should ensure free swinging and avoid unnecessary constraints. At the same time, the outer and inner pipes of the fixed rotary joint have left and right rotation, and attention should be paid to determining the rotation direction of the inner and outer pipes during installation and design.
2).Handle with care: Rotary joints should be handled with care during transportation and installation, and must not be subjected to impact or collision to avoid damaging the joint components.
In summary, by proper use, regular maintenance, lubrication, and attention to details during long-term storage and installation, the service life of rotary joints can be significantly extended. The implementation of these measures not only helps to reduce the failure rate, but also improves the overall performance and operational efficiency of the equipment.
