The purpose of the seal in the rotary joint is to seal the connection and allow one of the two pipeline sections to rotate relative to the other. At the same time, in order to reduce the pressure drop across the connection. Therefore, it is best to place the rotary joint seal in the enlarged axial portion of the entire fluid bearing channel formed by the pipeline section...

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....

Rotary joints are mainly used in rubber product production for fluid (steam, thermal oil, cooling water) pathways of rotating components such as internal mixers, open mixers, calenders, extruders, and vulcanization equipment...
View detailsSilicon 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...
