The central swivel joint can be called multi-pass swivel joint, liquid slip ring, confluence ring, and the main feature of the center swivel joint is that it has a good sealing structure, and transmits the same medium source to the working parts in any direction, and the structure is more active. change.
The central rotary joint is literally explained as a rotary joint that can recover the medium around the same center. This joint is convenient, safe, and stable in performance, saving energy waste in terms of economy. Rejected environmental pollution, the general center rotary joint is made of porous, porous, such as 2 holes into the medium, 2 holes out of the medium, this is the standard rotary joint, sometimes according to the working environment, need 2 The hole enters the medium, four holes or even a plurality of holes out of the medium. Sometimes, in order to reduce the size of the joint, a plurality of holes can be introduced into the medium, and the same hole can be discharged from the medium. In this case, the working joint is called a center rotary joint. Very flexible and convenient. Now, from an economic point of view, if there are more air intake holes, the size of the joint is relatively larger, and the processing time is relatively longer. The price of internal seals, bearings and other accessories is relatively high. It is a little expensive, and the cost is increased for the manufacturer. Therefore, when the rotary joint is purchased in the procurement center, it should be selected according to the specific working conditions. The heart-turn joint has good sealing performance, no leakage, etc., which reduces the maintenance cost of the user and reduces energy waste. From the environmental point of view, when the medium passes through the center swivel joint, when the medium source passes the required parts, When the parts are recycled, the direction of the medium can be recovered to the medium source by the power of the motor, so that the energy can be reused without waste, so that the user can reduce the cost and not pollute the environment, and the central swivel joint has another feature. The medium inlet hole can be accessed from the upper end of the flange or the side of the flange. The installation method can be county-mounted, contact type, horizontal and vertical type, etc. According to the working environment, the medium entering mode and installation mode of the center rotary joint are determined. The important thing is the structure of the seal. The most important part of the seal is the wear resistance. In order to ensure the good sealing of the swivel joint, the imported Teflon material is used to make the seal. This material has both wear resistance, high temperature resistance and resistance. Acid and alkali, corrosion resistance and many other features, the swivel joint consists of two high precision shafts Front and rear support, so that the center swivel joint can rotate at high speed quickly and smoothly. The hollow turn is made of stainless steel. After finishing, it can be used to check whether the hollow turn is processed and balanced. The level measuring instrument is used for measurement. Only a good level can guarantee good. The concentricity, so that the center rotary joint can be more stable when rotating, the concentricity is higher, the hollow shaft surface is smooth, the internal friction is effectively reduced, thereby prolonging the service life of the rotary joint, the joint is mechanically balanced and the appearance is European-style. The design style and design style are already in line with international standards.
