The inner parts of the waterproof slip ring mainly include the rotor, the stator located in the inner part of the rotor and the chassis for fixing the stator.The water of the slip ring structure and working principle is as follows: the center of rotation of the stator fixed installed in the chassis, the rotor through the bearings with the stator rotating, rotating platform through the lever to drive the stator rotating, the input cable transmission through the stator on gold-plated conductive ring to the stator's inner hole in connection, to introduce the power and the input signal.

However, to install the rotor of the water-slip ring, many gold alloy brushwires need to be fixed on the bracket. These brushwires contact and slide with the conductive ring, so as to realize power supply and point signal transmission.In addition, the rotor of the water-slip ring is covered with a sealed aluminum alloy cylinder, bolted and sealed with an industrial sealant.A plurality of output power connection piles are arranged on the sealed aluminum alloy cylinder of the water-slipping ring, and these power connection piles are connected with the aluminum alloy cylinder by cables, so that the water-slipping ring can realize the transmission of power and electrical signals.

The contact materials of waterproof slip ring components are mainly precious metal and super-hard gold plating, and the contact method is family brush plating multi-point contact.Therefore, this kind of water-slip ring has reliable contact, small heat, small friction torque, stable operation, long wear life, small contact resistance, small resistance fluctuation, and excellent transmission performance.In addition, the shell material is made of aluminum alloy, which not only meets the strength requirements of the conductive ring, but also dissipates heat quickly. Heat dissipation does not need to be considered when passing through large current.At the same time, the water-slip ring adopts the internal strong and weak electric isolation and special shielding module, which is suitable for port tyre crane to transmit both power supply and various microelectric control signals.In addition, the water-proof design of the water-slip ring adopts the out-line water-proof gran, which is suitable for the working conditions of port type cranes under bad environment such as ports, docks and freight yards.The conductive ring assembly adopts hollow structure, which is advantageous to the port tire crane to transmit the compressed air, hydraulic oil and other fluid medium between the conductive slip ring.
