****What is the specification of the conductive slip ring used for the shore power cable reel?
Recently, the state issued the Measures for the Administration of Port and Ship Shore Power, which is mainly to prevent and control the atmospheric pollution caused by ship emissions. The use of shore power during ship berthing is the most effective way to reduce atmospheric pollutants such as sulfur oxides, nitrogen oxides and particulate matter, and reduce noise pollution. The shore power reel requires conductive slip ring, which is a kind of device that can transmit power and signals between 360 ° rotating devices to avoid twisting and winding of the device during rotating. It is usually installed in the center of the device and is composed of stator and rotor.
Generally speaking, there are three different specifications of conductive slip rings for shore power drums, including high current and low current, which are suitable for different ship shore power drums. In response to national policies, many shipping companies have started to take action. At present, Jiachi Electromechanical has designed and produced several batches of shore conductive slip rings for many shipping companies, which have been put into use by customers in succession, and have received good response. If you are also in the shipbuilding industry and do not know how to choose the shore conductance slip ring, you can consult the customer service of JARCH Electromechanical, and they will design a slip ring suitable for you according to your needs.
****What is the internal structure of the conductive slip ring?
The conductive slip ring is a mechanical part that can transmit power, signal, network, gas and other media between rotating bodies without twisting, winding and other problems. The conductive slip ring forms a stable and reliable rotary communication system with respect to the material selection, reasonable design, and precise manufacturing and coordination of components. Then what kind of structure does the conductive slip ring have inside? The following small series will analyze the conductive slip ring of Jiachi Electromechanical.
The conductive slip ring is mainly composed of slip ring body, combined support, centripetal ball bearing, bearing end cover and other parts, and is also divided into stator and rotor. The "rotor" part connects the rotating structure of the equipment and rotates with it, and the "stator" part connects the energy source of the fixed structure of the equipment. The design structure between the rotor and stator is a precise superposition of single paths. The number of superposed paths is determined according to the customer's needs. The paths between the rotor and stator are one-to-one corresponding. The electrical performance of each path is independent of each other and will not cause interference. The brush wire of the slip ring is made of special precious metal alloy material, which has the advantages of oxidation resistance, corrosion resistance, high life and wear resistance. The multi-point contact process of single ring double brush and double ring four brush is used between the slip ring and the electric brush, which greatly improves the stability of the conductive slip ring when transmitting power and signals.
