Installation Instructions of deublin hydraulic rotary union
The installation details of the Deublin hydraulic rotary union are crucial. It not only affects the normal operation of the equipment, but also directly affects the production efficiency and equipment life. The following are the detailed installation steps and precautions of the deublin rotary union:
1. Preliminary preparation
Before installation, be sure to ensure the cleanliness of the Deublin hydraulic rotary joint drum and the inside of the pipe. According to the actual use needs, a filter can be added to effectively prevent foreign matter from entering the rotary joint and causing wear. At the same time, it is also necessary to ensure the reliability of the operation of the rotary joint bearing, which is the basis for ensuring the normal operation of the rotary joint.
2. Handling and storage
The Deublin hydraulic rotary union should avoid collision and falling during transportation and storage to avoid damage to the interface and internal parts. Handling with care is the key, which can effectively prevent damage or deformation of components caused by accidents.
3. Concentricity adjustment
Install the machine concentrically as much as possible to ensure the good operation of the rotary joint. If the concentricity is not good, it may cause additional friction and wear of the rotary joint during operation, thereby shortening the service life.
4. Threaded connection
For the threaded rotary joint, special attention should be paid to whether the thread direction of the inner and outer tubes corresponds to the rotation direction of the drum during installation, and the thread rotation direction of the inner and outer tubes should also be consistent. An incorrectly threaded connection may cause the rotary joint to fail to install normally or leak during use.
5. Hose connection
Connect the rotary joint to the pipeline using a hose—preferably a metal hose with strong interference resistance—and strictly avoid any rigid connections. Hose connection can reduce the auxiliary weight of the joint, extend the service life, and absorb the vibration and displacement generated during the operation of the rotary joint to a certain extent.
6. Size matching
The assembling the inner tube should pay attention to the size matching and weight auxiliary support. We recommend using an H8/e7 tolerance fit for the inner tube and the joint of the internal rotating rotary joint to ensure a tight fit and stable operation.
7. Support and anti-rotation
The support and anti-rotation of the rotary joint should be appropriate. Generally, the rod diameter should be about 2mm smaller than the anti-rotation hole to avoid affecting the free adjustment and compensation ability of the rotary joint. Correct support and anti-rotation can ensure that the rotary joint maintains a stable position and posture during operation.
8. Oiling maintenance
Rotary joints with oiling devices should be oiled regularly to ensure the reliability of the operation of the rotary joint bearings. Since the long-term non-use of the machine may cause scaling and rusting inside the rotary joint, regular maintenance is required even if it is not used.
9. Temperature control
Operators should gradually heat rotary joints that circulate hot media to avoid sudden temperature changes. Rapid temperature changes may cause uneven thermal expansion and contraction of the internal parts of the rotary joint, causing leakage or other failures. Operators must carefully manage every step, from preliminary preparation to later maintenance. By strictly following the installation specifications, they ensure the rotary joint operates normally and lasts longer.”
The installation of the Dubolin rotary joint requires meticulous attention to every detail. Carefully preparing in advance and thoroughly maintaining the equipment at every stage ensures the rotary joint operates normally and extends its service life by strictly following the installation specifications.
