Slip Rings for Medical Equipment

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. Slip ring is also called rotary electrical joint, collector or electric swivel. A slip ring can be used in any electromechanical system that requires unrestrained, intermittent or continuous rotation while transmitting power and/or data/signal. Slip ring can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.

The slip rings adopt the advanced precious metal fiber brush wire technology and unique shielding method to ensure reliable signal, low working voltage, low abrasion, and low loss contacting design, which exactly realize longer life time and free maintenance. Slip rings has been widely used on medical equipment, such as shadowless lamp, CT machine and monitoring machine.

Slip rings for Energy (Wind Turbine Generator)

Today, wind is one of the fastest growing energy technologies. Wind power involves converting wind energy into electricity by using wind turbines. The slip ring can be part of a large wind turbine electric pitch control system with the option to integrate hydraulic pitch control systems if required. Modern wind turbines require delivery of power and signals to and from the rotating blades by a reliable rotary union assembly. Obviously the quality of the slip ring is a key determinant in the quality of the overall wind turbine generation system.

Slip rings are mostly used to provide electrical signal and power for blade pitch power and control. In the hydraulic system, slip ring and fluid rotary union need to be combined to provide multiple signals, electric and hydraulic power transmission for the hydraulic blade pitch actuation. In the electric system, it need slip ring with higher power circuits transmit signals and electric power for the electric blade pitch actuation. High power slip ring is needed to provide high current transmission for energizing the rotor coils in the direct drive system.

Nowadays, around 10 percent of wind turbine slip ring in the market are using fiber brush contact materials. This kind of slip ring only need to be maintained rarely. Another 60 percent of slip ring in the market are made of composite metal brush, normally combined with metal and graphite, they require maintenance frequently. The remaining 30 percent wind turbine slip ring adopt single precious metal brush, with better performance than above two types. The main reason is that composite metal brush design can wear brush in advance to avoid slip ring attrition. But composite metal brush materials is very sensitive to humidity. If Humidity is lower than 15% or higher than 85%, it could lead to uneven wearing. The other problem is that when it is used for signal circuits, these composite metal brush will occupy a great of space.

The slip rings for wind industry need to be designed to match harsh environment. Usually they need to resist extreme high or low temperature, invasion of sand & dust and corrosion of seawater.

Marine Slip Ring

Marine application has extreme requirements of slip rings due to its harsh marine environment and increasing transmission requirements. Marine slip rings are performing their function in underwater vehicles, marine satellite antenna systems, marine winches, sonar devices, seismic and oceanographic exploration equipments. Remotely operated vehicles (ROVs) and satellite communication systems as two important end-users of slip rings in marine application. The growing use of underwater robots for deepwater oil and gas industry promotes the development of ROV slip ring systems. Slip rings used in deepwater must withstand extreme underwater environments such pressure and shock and corrosion. Satellite antenna communication system can automatically identify, acquire, and track satellite signals, it is essential for marine communication from the target to remote monitoring location. It contains three key elements—RF cable, RF connector and antenna. Antenna is the first element of the input system to wireless signal receiving system, because antenna system enables two way communications between the ground and another fast moving station, then people can track radar, airplane, boast and moving vehicles from monitoring station. As antenna system must be driven in 360° horizontal or vertical rotation, so it needs a slip ring to incorporate into the antenna system to solve voltage and signal control from one stationary part to rotor part.
