The hydraulic rotatory slip ring is a key hydraulic transmission equipment with 360° rotations in any directions. It is widely applied in large-scale complete sets of electromechanical equipment in mining industry, petrochemical industry, lifting device, machinery, scientific research, military and metallurgical industry. The hydraulic slip ring produced by Hong Yuan can provide stable quality with over 5-years life cycle. Now it occupies over 60% market share in the domestic metallurgy industry. 

The electro-hybrid-hydraulic rotary slip ring, designed and developed by Hong Yuan, can realize 360° rotation in any direction, transmitting power supply, control signal power, and micro-electricity signal for computerized automatic control system. The product is widely applied in large-scale complete sets of electromechanical equipment in mining industry, petrochemical industry, lifting device, machinery, scientific research and metallurgical industry. For example, it can be used for large-barrel rotary table for steel nozzle, drilling platform and steel-making converter support ring for continuous casting machine.

The electro-hybrid slip ring is designed with three conductive forms, namely, strong electricity, control signals, and millivolt-level sensor electrical signals. The signal source is shielded against interference. The sealed moisture-proof structure prevents the water droplets inside the slip ring from damaging the insulation performance between the joints in wet weather, thereby improving the reliability and service life of the product. In the electro-hybrid slip ring, a special control method combined with digital control function and half-ring automatic switching of dual-power-supply functions are also applied. In addition, a dynamic ring extraction device with a uniquely rigid structure and a mounting function is also designed. The slip ring can be rotated without interference by the torque in any directions. It can greatly reduce the wear on the bearing, the sealing member and the over-current device, and hence, improves the service life of the slip ring.

The hydro-hybrid rotary slip ring is made of special materials by special tooling and heating treatment processes. The radial runout of the slip ring is less than 0.02mm. The working pressure is no more than 40MPa, and the working flow per channel is between 0-500L/min.

The internal bearings of the hydro-hybrid slip ring are all of SKF products, and the high-low pressure rotary seals are all best quality seals. Since the slip ring is the key equipment for steel making, our company fully considers the service life and guarantees the 24-months warranty period. The hydro-hybrid slip rings produced by our company have been well recognized in the application of many metallurgical industry and metallurgical design institutes in China.

Power supply: The isolation voltage between the connectors is not less than 2000V; the allowance for electric current is 30A; the maximum decrease on voltage is no more than 1V.

Micro-power signal: It can transmit mA-level current signal of mV-level voltage signal.
