Use of the pneumatic liquid slip rings

The media guides of our pneumatic liquid slip rings are not exclusive. This means that we can pass both liquid and a pressurised gas in this series. This makes very interesting combinations possible. In addition to the transmission of pneumatic or hydraulic energy, this also allows auxiliary and operating materials, such as coolants, cleaning agents or lubricants, to pass through. The possible applications are thus practically unlimited.

However, these powerful slip rings are particularly popular for construction vehicles. Especially wheeled and tracked excavators with a rotating superstructure and hydraulic propulsion have at least one hydroelectric feed-through in the undercarriage. This allows the engine and hydraulic unit to be conveniently accommodated in the rotating superstructure and still reliably supply the rotating motors of the undercarriage with hydraulic pressure. Another application for these particularly powerful slip rings is in wind turbines. Here they are mainly used for hydraulic control of the rotor blade adjustment. They can transmit sensor data or luminous flux simultaneously with a hydraulic pressure that optimally turns the rotor blades into the wind.
