RMH series high-voltage high-speed rotary joint

High speed and high-pressure rotary joint is a closed rotary connector that can operate stably in unconventional high-speed and high-pressure environments, mainly used for 360 ° rotation to transport liquids, gases and other media. Adopting stainless steel material and a sealed structural design, it is compatible with metal hoses and threaded connection interfaces. Through technologies such as high-temperature resistant bearings, multi-layer sealing components, and double tapered roller bearings, it can operate under extreme working conditions with a pressure resistance of 250MPa, a speed of 8000rpm, and a temperature resistance of 300 ℃ [1-2]. Some products adopt floating seal design or piston balance compensation structure, combined with computer optimized corrugated tube technology, to achieve low friction, automatic concentricity, and wear compensation functions

1. 2-4 independent channels, static pressure independent bearing design;
2. The shell is made of hard aluminum alloy, which is lightweight and has good heat dissipation;
3. The rotating core shaft is treated with alloy steel and hardened;
4. Maze type gap sealing structure, suitable for high-speed and high-pressure working conditions;
5. Unique drainage hole design to prevent leakage to the external environment;
