The full sealing rotary joint, characterized in that the rotary joint main sector is a stainless steel ring supports the V-shaped sealing body, and the sealing body employs a polytetrafluoroethylene material having self-lubricating function, auxiliary sealing is a plurality of O-sealing rings, rotary joint O-shaped The seal is placed in the rotating shaft and the pressure ring trench. The rotary joint press ring and the housing are threaded, and the degree of main sealing is adjusted by changing the number of threads of the housing.
The rotating adapter rotation shaft, the housing and the pressure ring use 316 or 304 stainless steel material, the ball is made of ceramic material, the roller is hardened and polished, and the rotary joint tight cover is polished. The rotary joint will be worn after use. For example, if you wear shoes, you will find the sole that is wear, but the horizontal part is different.
The rotary joint wear is a mechanical effect between solid and other components or media. The appearance of the joint is destroyed. When the rotary joint is worn,bite type fitting Factory the damage is limited to a small range of data, and the friction surface is gradually removed from the friction surface. The wear amount of the rotary joint is typically reduced according to the vertical size of the object along the friction surface.
The wear of the rotary joint occurs on the surface of the local friction fitting, wherein the two friction bodies are in contact with each other. The sum of these friction nodes combines the actual contact area of the two objects; the contact area is carried out in fixed wear mode.
Invisible, when an object reaches the homogeneous diameter of the contact point with respect to another object, the existing rotary joint friction node is destroyed, and a new number of new friction nodes are generated, and any point on the outer surface. Something. The rotary joint friction node is a complete load cycle, which is a sliding slide of the uniform diameter of the contact point, which can be considered a mutual unit effect.
