What is a multi-channel rotary joint? Under the current definition, we call the operation of multi-channel rotary joint, which is designed independently within the same joint and does not interfere with each other. It has powerful functions and can simultaneously import different media, such as water, steam, oil, air, vacuum and cutting fluid. Chemical reagents, acidic and alkaline fluids, etc., and different media can enter and leave the media through the holes on the side or above according to their working conditions. It is widely used in papermaking equipment, printing equipment, CNC workbench, rubber equipment, continuous caster, special equipment for iron and steel industry, chemical equipment, plastic manufacturing equipment, petroleum exploration equipment, etc. Many rotating platform and rotating platform components need to be realized by multi-channel rotary joints. With the development of industry, multi-channel rotary joints are now available in high-end fields such as automation equipment, automation testing equipment, aerospace equipment, automated robots, manipulators, solar energy equipment and so on. To a wider range of applications. The performance, structure and parameters of multi-channel rotary joints put forward higher requirements, so for the current manufacturers of rotary joints, in order to meet the needs of these high-end fields, R&D funds are invested in the development of new products and new structures. Because the quantity of these new multi-channel rotary joints is not very large, many of them are needed. To customize the design and production, so the price of a single number of high-pass spindle rotary joints is also called multi-channel rotary joints. What is the universal spindle rotary joint?

The structure of rotary joint is varied. According to different classification methods such as structure and application field, the rotary joint can also be classified according to the number of holes set up by working requirements, such as Hindley 2, 3, 4, 6, etc. Each inner tube can operate independently and without interference through the rotor. The medium transmission between the rotating structure and the rotating structure is accomplished by the cooperation of stator and stator. This kind of unrestricted continuous rotation also requires some basic parameters and sealing performance of the rotating joint. The basic technical parameters are mainly threaded size, pressure, temperature, pipe diameter size, maximum rotating speed and so on. Can there be leakage, leakage of liquid, wear resistance, corrosion resistance, etc. Among the basic technical parameters of multi-channel rotary joint, the minimum diameter and length of the rotor are determined by the number of channels and the diameter of the pipeline, while the diameter of the pipeline is mainly determined by the thread of the outer pipe link when the work needs. At the same time, because the multi-channel joint can pass through various media, sometimes some parameters may be required to be proportional to each other. Higher, such as high speed 1000rpm, high temperature 400 degrees, high pressure 100MPa through corrosive medium, etc. These parameters determine the sealing, high temperature resistance, high speed, high pressure and multi-channel rotary joint. These parameters are very important. They also determine the material used in manufacturing. They are also an important determinant of the price of multi-channel rotary joint. The number of multi-channel rotary joint paths ranges from 2 to 26. The number and price of paths vary greatly with different requirements. Therefore, in the manufacturing process, the more the number of paths, the more complex the manufacturing process. In order to operate better under high-speed, high-pressure and high-temperature conditions, it is necessary to use imported bearings and seals. Two high-precision bearings support the rotor. High-speed, smooth and effective work. Such a structure can reduce the internal friction coefficient, strong and zero-activity, high temperature resistance, wear resistance, corrosion resistance, no degassing, sealing parts are developed from polymer materials, these parameters are also the factors of high cost of multi-channel rotary joints, the end face of the joints is sealed by high-pressure mechanical balance, so as to ensure the internal. The concentricity of the structure can greatly reduce the internal friction and prolong the service life of the rotary joint.
