Application and Testing of High-Pressure Rotating Joints

1. Firstly, try to use high-pressure rotary joint interfaces during installation and connect them to the machine with hoses. Adopting optimal support to reduce auxiliary weight and vibration, effectively extending the service life of high-pressure rotary joints. The support and stopping rotation of high-pressure rotary joints should be appropriate. In general, the diameter of the rod should be 1-3mm smaller than the anti rotation hole to avoid affecting the compensation and free adjustment of the high-pressure rotary joint.

2. When assembling the inner tube, pay attention to size matching and weight distribution. It is recommended to use E7/H8 tolerance fitting for the fit between the high-pressure rotary joint inner pipe and the joint. The connection between high-pressure rotary joints and pipelines must be made with hoses, and steel connections are strictly prohibited.
3. There is an oil injection device, please inject oil regularly to ensure the reliability of the high-pressure rotating joint bearing operation. Due to long-term disuse of the machine, it can cause scaling and rusting inside the high-pressure rotary joint. Please note that it may get stuck or drip when reused. The high-pressure rotary joint of the heat medium should be gradually heated to avoid sudden temperature changes. It is strictly prohibited for foreign objects to enter the rotating joint. The rotary joint cannot idle for a long time.
4. The high-pressure rotary joint has been precision manufactured, and collision should be avoided during handling and storage to avoid damaging the interface and internal parts. During installation, it should be concentric with the connecting shaft to ensure the good operation of the high-pressure rotary joint. When installing high-pressure rotary joints with threaded connections, attention should be paid to whether the thread direction of the inner and outer pipes is consistent with the rotation direction of the rollers, and the thread direction of the inner and outer pipes should also be consistent.
5. How to test high-pressure rotary joints?
Test the technical parameters of the product, such as pressure, speed, temperature, etc. Finally, there are also some data, such as the service life test, seismic test, and axle load test of the high-pressure rotary joint. Test the various indicators of the high-pressure rotary joint in a constant environment, record the test data, and effectively analyze the characteristics of the product and the application environment. This will ensure the quality of the product, I assure you.
6. Try to rotate the high-pressure rotary joint. Sometimes the medium will circulate during use, but the high-pressure rotary joint is fixed. This situation can lead to uneven traffic. In the long run, if there is an imbalance elsewhere, it will intensify the wear of a joint surface and reduce its service life
