Jan 01, 2024

What is a multi-channel rotary joint? In the current definition, we refer to the operation of multiple pipelines independently designed within the same joint without interfering with each other as a multi-channel rotary joint. It has powerful functions and can simultaneously introduce different media, such as water, steam, oil, air, vacuum, cutting fluid, chemical agents, acidic and alkaline fluids, etc. Different media can enter and exit the media from the side or upper holes according to the working conditions. It is widely used in papermaking equipment, printing equipment, CNC workbenches, rubber equipment, continuous casting machines, steel industry specific equipment, chemical equipment, plastic manufacturing equipment, petroleum exploration equipment, etc. In many rotating platforms and rotating platform structures, components of the rotating media need to pass through Multi channel rotary joints are used to achieve this, and with the development of industry, Nowadays, multi-path rotary joints have been widely used in high-end fields such as automation equipment, automation detection equipment, aerospace equipment, automation robots, robotic arms, and solar energy equipment. The performance, structure, and parameters of multi-channel rotary joints pose higher requirements. Therefore, for current manufacturers of rotary joints, in order to meet the needs of these high-end fields, research and development funds are invested in the development of new products and structures. As the quantity of these new multi-channel rotary joints is not very large, many of them require customized design and production. Therefore, the price of a single quantity is higher than that of a Qualcomm spindle rotary joint, also known as a multi-channel rotary joint. What is a Qualcomm spindle rotary joint?

 

There are various types of structures for rotary joints, and according to different classification methods such as structure and application field, the number of holes set for the through-hole rotary joint can also be classified according to work requirements, such as the Hindley 2-way, 3-way, 4-way, 6-way series, etc. Each inner tube can operate independently without interference, and the medium transmission between the rotating structure and the rotating structure is completed through the mutual cooperation of the rotor and stator. This unrestricted continuous rotation also requires some basic parameters and sealing performance of the rotary joint. The basic technical parameters mainly include joint thread size, pressure, temperature, pipe diameter size, maximum speed, etc. The sealing performance includes whether there is air leakage, liquid leakage, wear resistance, corrosion resistance, etc. In the basic technical parameters of a multi-channel rotary joint, the minimum diameter and length of the rotor are determined by the number of paths and the diameter of the path, while the diameter of the path is mainly determined by the thread of the outer pipe connection when needed for work. At the same time, because multi-channel joints can pass through multiple media, sometimes some parameters may require higher requirements, such as high-speed 1000rpm, high temperature 400 ° C, and high-pressure 100mpa for corrosive media. These parameters determine the sealing and high temperature resistance of the rotary joint, including high speed, high pressure, and multi-channel rotary joints. These parameters are very important and also determine the material used in manufacturing. They are also an important determining factor in the price of multi-channel rotary joints. The number of channels for multi-channel rotary joints varies from 2 to 26, and different requirements result in significant price differences in the number of channels. Therefore, in the manufacturing process, the more channels there are, the more complex the manufacturing process. In order to better operate quickly under high-speed, high-pressure, and high temperature conditions, imported bearings and seals must be used. These two high-precision bearings support the high-speed, smooth, and effective operation of the rotor. This structure can reduce the internal friction coefficient, be sturdy and flexible, and the sealing element is resistant to high temperature, wear, corrosion, and air leakage. The sealing element is developed from polymer materials, and these parameters are also a factor in the high cost of multi-channel rotary joints. The joint end face adopts high-pressure mechanical balance sealing, which can ensure the concentricity of the internal structure, greatly reducing internal friction and extending the service life of the rotary joint.
