How to maintain high speed rotary joints

 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.

How Do Power Lines Work?

图片
  Electricity is delivered to homes, schools, hospitals, businesses and industries through an integrated system of power plants, power lines and substations. Transmission lines consist of heavy-duty cables wound between tall towers that carry electricity from where it is generated to where it is needed. Transmission networks allow for the transmission of large amounts of electricity over long distances.   Power systems involve the generation, transmission and distribution of electricity. As the demand for electricity grew and small power plants that could only serve local areas became inadequate, the need for high-capacity transmission arose. Newer, larger power plants come online, but far from load centers. Transmission lines were the only way to get power to where it was needed.   Most long-distance power lines do not use insulation around the conductors themselves. Insulation in this way must be so thick that it is not cost effective. Instead, most of the insulation comes from the a

What are the main functions of HPMC in a dry mix mortar?

    The roles of  HPMC  for  dry mix mortar In dry mix mortar, Adding a little HPMC can significantly improve the performance of wet mortar. It can be seen that HPMC is a major additive that affects the construction performance of mortar. 1. Water retention Water retention is an important property of HPMC. The viscosity, dosage, environmental temperature and molecular structure of HPMC have a greater impact on its water retention performance. Under the same conditions, the higher the viscosity of HPMC, the better the water retention; The higher content, the better the water retention. Generally, a small amount of HPMC can greatly increase the water retention rate of the mortar. When the content reaches a certain level, The trend of the water retention increasing slows down; as the ambient temperature increases, the water retention of  HPMC  usually decreases, but some modified HPMC also have better water retention under high temperature conditions; HPMC with lower substitution degree h

Metal Grating: Everything You Need to Know

图片
What is Metal Grating? The word “grating” may apply to a number of metal items, in metal industries. Each form has its own collection of distinct characteristics that make it more or less suitable for the specific use. Street drains, for example, will usually use a type of bar grating, while walkways are generally used in a safer type of extended grating or grip strut. Metal grating, regardless of the actual use, provides for adequate drainage, ventilation, and protective precautions in a number of industries. Different types of  Metal Grating Metal Grating are widely different in both materials and purpose. Various types of metals and various types of production are used to make sure that the operating systems are safe, based on its applications. Also it depend on various parameters like strength and size, its location and usage. Expanded Metal Gratings Expanded Metal Gratings are metal gratings which are made through split in a metal sheets, and then the sheets are expanded, into a d
