The core steps of the inlet and outlet water connection of the rotary joints
Flexible pipes (such as metal hoses) must be used to connect the inlet and outlet, and it is prohibited Rigid pipe To compensate for the axial displacement and concentricity deviation of the rotary joint. The length of the hose should be sufficient to avoid twisting or excessive stretching

How to replace the O-ring of the rotary joints
ensure that the equipment has stopped running and completely released the fluid pressure (water, oil, or gas) inside the joint. Disconnect the connector from the equipment and remove it from the spindle or pipeline. If the joint is equipped with a flange or threaded connection, use a suitable tool to loosen the fastener.

Why do high-speed rotary joint need to be sealed with silicon carbide
Silicon carbide rings are sintered at high temperatures, and the flat surface is a mirror surface polished with diamond. The characteristics are high hardness, high temperature resistance, and friction resistance. Silicon carbide ring and graphite friction seal, because the powder nature of graphite produces a sealing ring effect. Impurities are difficult to enter the sealing end face

Working principle of pneumatic multi-path rotary joints
We independently design multiple channels on a single pneumatic rotary joint product, which can simultaneously transmit compressed air, vacuum hydrogen, nitrogen vapor, and other gas media in any 360 degree rotating operation without interfering with each other. This is called a pneumatic multi-path rotary joint
