| The cooling water rotary joint is also called the H-type cooling water rotary joint, which is a kind of internal bearing support. swivel joint. The internal structure of the H-type cooling water rotary joint is roughly divided into springs, rubber gaskets, copper tin, O-rings, and graphite sealing rings. The structure is simple, the maintenance is convenient, and the sealing is reliable. The working principle of the cooling water rotary joint: The hollow shaft is directly connected to the roller through threads or flanges, and is the main rotating part; the sealing structure combines the characteristics of the Q-type (built-in seal) and D-type cooling water rotary joint (rolling bearing support) structure. The balanced seal design is adopted so that the working pressure produces almost equal pressure on both ends of the seal ring, thereby effectively reducing the The wear of the sealing end face caused by the sealing load is avoided, and the service life is prolonged; the support of the rolling bearing to the hollow shaft greatly reduces the rotational torque, and the operation is flexible, plus the volume is small and the weight is light. Therefore, the cooling water rotary joint can be applied to higher speed conditions. In addition, the casing is provided with an observation hole, through which the leakage and wear of the seal can be observed.
