The internal parts of the water-slip ring mainly include a rotor, a stator located inside the rotor and a 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, the installation of the water-slip ring rotor requires a number of gold alloy brush wires fixed on the bracket. These brush wires touch and slide with the conductive ring to realize the transmission of power supply and point signals.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 power supply connecting piles are arranged on the sealed aluminum alloy cylinder of the water-slip ring, and these power supply connecting piles are connected with the aluminum alloy cylinder through cables, so that the power and electrical signals of the water-slip ring can be transmitted.
The contact materials of the water-slip ring components are mainly precious metals and super-hard gold plating, and the contact mode is family brush plating multi-point contact.Therefore, the water slip ring has reliable contact, small heat, small friction torque, stable operation, long wear-resisting 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 fast heat dissipation, and does not need to consider heat dissipation when passing a large current.At the same time, the water-slip ring adopts internal strong and weak electrical isolation and special shielding module, which is suitable for the port tire crane, which transmits both power supply and various micro-electric control signals.In addition, the waterproof design of the water-slip ring adopts the off-line waterproof gran, which is suitable for the working conditions of the port tire crane in the harsh environment of the port, wharf, cargo yard, etc.The conductive ring assembly adopts hollow structure, which is conducive to the port tire crane to transfer compressed air, hydraulic oil and other fluid media between the conductive slip rings.
