Structural characteristics

HD series rotary joints are mainly designed for cooling system, it has the advantages of small volume, light weight, small friction torque, etc., and adopts balanced sealing structure, the friction beam material according to different media environment, there are impregnated graphite, bronze, silicon carbide, etc., a variety of material pairs to choose from, enough to resist the rust, scaling, and other impurities on the sealing surface of the sealing surface, and the sealing surface after the surface finishing process, the surface is like a mirror, the seal is more reliable. The sealing surface is mirror-like after finishing process, which makes the sealing more reliable and the service life longer. There are unidirectional, bidirectional internal solid type and bidirectional internal rotary type. Mainly used in fire water pan, fire water bag reel, fire water cannon, refining machine, opening machine, screw extruder, film machine, drum clutch, cold cylinder, press roll, stone roller, paddle shaft, cable reel, burnishing machine and other cooling equipment.

HD type rotary joints Unidirectional flow type - threaded connection
