How To Maintain High Speed Rotary Union To Extend Service Life？

High-speed rotary union is a type of rotary joint. High-speed rotary joints are used for high-speed interface transmission media. High-speed rotary joints are different from ordinary rotary joints, so you must pay special attention to them during normal use. Now let's take a look at the daily maintenance of high-speed rotary joints.

High Speed Rotary Union

Maintenance Methods

1. Sealing surface

Check the wear condition and thickness change of the sealing surface (generally, the normal wear is 5-10mm); observe the friction track of the sealing surface to see if there are three-point discontinuity or scratches. If these problems occur, don't hesitate to replace the rotary joint immediately.

2. Clean regularly

Special attention should be paid to the inside of the rotary joint drum and pipeline, and a filter should be added when necessary. This is because many foreign objects will cause strong wear on the rotary joint, and frequent cleaning can effectively extend the service life of the rotary joint.

3. Long-term non-use

If the general machine is not used for a long time, it will cause scaling and rust inside the rotary joint. If it is used suddenly, it will get stuck or drip.

4. Regular oil injection

The oil injection device should be oiled regularly to ensure the reliability of the rotary joint bearing operation. Rotary joints that circulate heating medium should gradually generate temperature to avoid sudden temperature changes.

Tip: Generally, after the high speed rotary union is used, a lot of small deposits will appear. In this case, if the machine stops running, the rotary joint must be folded down for cleaning, and stored properly, and then installed when the machine needs to run. This method can significantly increase the service life of the high speed rotary union.

Additional Advice

ㆍA prolonged shutdown of the equipment will result in rust damage to the rotary joint, which will become stuck or leak when the machine is started.

ㆍWhen the rotary shaft rotates, the concentricity is too low, it should stop operation immediately and be replaced in time to prevent accidents and injuries.

ㆍThe medium outlet of rotary joint must use hose, Txuan recommended to choose flexible metal bellows.

ㆍIf fittings (valve,filter) are needed at the outlet of the rotary joint, they can be added to the pipe at the back of the hose .

ㆍInstall a fixed support device to ensure the swivel is swinging.

ㆍIn the installation and design of the inner tube fixed rotary joint, attention should be paid to the inner tube and outer tube rotation, because there are left and right rotation.

ㆍSelect the matching rotary joint according to the working condition（such as Media, Size, Temperature, Speed, Connection type, Direction of rotation, etc ）

ㆍThe inner tube of the rotary joint should be selected at an appropriate length, considering the weight and siphon effect of the rotary joint.

ㆍWhen using threaded swivel joints, pay attention to the specification of the thread and the length of the shaft head.

ㆍWhen the device is running without medium, do not run for long time.
