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.

Hongyuan Hydraulic's electric-hydraulic-pneumatic rotary slip ring/rotary joint is an integrated transmission device designed to realize the simultaneous transmission of electricity, hydraulic oil, and compressed air between stationary and rotating components. It features compact structure, reliable sealing performance, and low rotational resistance, ensuring stable and efficient energy and signal transmission in dynamic working conditions.

In terms of application scenarios, it is widely used in various industrial equipment that requires continuous rotation while transmitting multiple media. In construction machinery such as rotary drilling rigs and tower cranes, it enables the upper rotating part to receive hydraulic power, electrical signals, and pneumatic pressure from the fixed base during rotation. It is also applied in automated production lines, particularly in rotary worktables and robotic arms, ensuring uninterrupted transmission of energy and signals during 360-degree rotation. Additionally, it finds use in marine equipment and metallurgical machinery, adapting to harsh environments such as high humidity, dust, and vibration.

For installation methods, there are two common types: flange mounting and threaded mounting. Flange mounting involves securing the device to the equipment frame or rotating shaft via flanges, providing a firm and concentric connection, which is suitable for heavy-duty and high-precision applications. Threaded mounting uses external or internal threads to fasten the slip ring/joint, offering quick and convenient installation, ideal for light-duty and space-constrained scenarios.

In terms of structural forms, it is available in integrated and modular designs. The integrated structure combines the electrical, hydraulic, and pneumatic channels into a single unit, saving installation space and ensuring compactness. The modular structure allows for independent assembly of electrical, hydraulic, and pneumatic modules, facilitating maintenance and replacement of individual components according to specific needs.

Optional accessories include a dust cover, which protects the internal components from dust, debris, and moisture, extending the service life in harsh environments. A rotation speed sensor is also available, which monitors the rotational speed in real-time and feeds back data to the control system for operational adjustment. Additionally, high-temperature resistant seals can be opted for, enabling the device to work stably in high-temperature environments such as metallurgical processing.
