How to reduce the torque of pneumatic rotary joints

The main transmission medium of pneumatic rotary joints is gas, consisting of joints, solenoid valves, cylinders, and vacuum equipment. It has the characteristics of small size, light weight, and low friction torque, making the seal more stable and reliable.

The pneumatic rotary joint adopts two sealing forms: corrugated compensator and floating sealing ring, which make the sealing adjustable and repairable, making the sealing effect more reliable and stable; If the sealing device of the pneumatic rotary joint adopts an external structure, the end face pressure decreases, effectively reducing wear. Hollow shaft is the main body of a rotary joint, which is connected to rollers or rollers through threads or flanges, allowing the joint and connecting equipment to move synchronously; The sealing ring, hollow shaft, and corrugated compensator form a floating double end face. The sealing ring is made of impregnated carbon graphite, which has good self-lubricating effect, thereby reducing the friction and friction loss of the pneumatic rotary joint and improving the service life of the rotary joint.
After the sealing ring of the rotary joint wears out, the corrugated compensator can compensate at any time with the help of spring pressure. This bearing not only provides support, but also improves the accuracy of the joint and reduces the friction torque of the pneumatic rotary joint. Do not exceed the maximum pressure specified to prevent damage caused by overpressure. Ultra high temperatures can accelerate the deformation of sealing materials, causing leaks. If there is a malfunction, remove it immediately. Manually tapping, folding, or stretching can damage the performance of the rotary joint. Impurities may be mixed in during reinstallation. Particles can scratch the sealing ring of the rotary joint, leading to leakage over time. Dielectric properties also need to be considered. It is recommended to install a filter to ensure the cleanliness of the fluid. When installing pipe threads, it is best to wrap the original sealing material such as tape around the threads. Don’t exert too much force. If the screw is too tight, it will have the opposite effect. Sometimes the transmission instructions are flammable liquids, so there should be no open flames in the loading and unloading environment, and there should be no oil on the outside of the connecting hose. Don’t forget to lubricate and clean the rotating joint maintenance work.
