Slip Ring for Offshore Marine Industry
Generally speaking, the offshore marine industry use large volume slip rings. Such as large current slip rings, high power slip rings and high voltage slip rings can be seen on gantry cranes, floating cranes (ships), and other offshore engineering platforms. Slipring with box structure has many advantages, such as easier maintenance and less complicated manufacturing and assembly processes. Generally, use high current carbon brush slip rings, mostly maintainable box-type structures, and some models use semi-enclosed cylindrical structures.
Electrical Slip Ring for Offshore Application
We can see large size slip ring in professional equipment lifting ships, scientific research ships, ship crane, port crane, ship cable winch, shipboard radar, ship thruster and offshore oil drilling platforms. These different platforms use different offshore cranes with different tonnages and different application environments. This determines that the specific performance required of the slip rings they use is also different.
For example, offshore oil drilling platform crane use high current slip ring with explosion-proof performance. The representative model of WayDun Technology slipring is WDC0380-01-0280, which can meet the requirements of explosion-proof electrical equipment for explosive environments. Some platforms place high-current slip rings in a relatively open installation environment. So they have particularly high requirements for protection levels. They have a high protection level of IP66, which meets the needs of use in harsh sea conditions and other environments.
Ship crane is very important marine engineering equipment. They are mostly installed on large-tonnage professional construction ships and other special platforms. Compared with cranes on land, they have greater output power and stronger lifting capacity. Unlike land cranes that mostly use hydraulic equipment, most ship crane require high-power motors to support the retraction and release of lifting cables. Therefore, a conductive slip ring with high power and signal transmission capacity is generally integrated in the slewing center of the ship crane.
In order to transmit greater power, offshore crane conductive slip ring make use of carbon brushes to contact copper rings. In addition, their structures are mostly overhead to facilitate heat dissipation.
Among the conductive slip rings developed by WayDun technology for offshore cranes. There are even models with integrated radiators. The radiator works under the control of the temperature sensor. Once the internal temperature of the conductive slip ring exceeds the set value, the radiator will start working to ensure that the offshore crane can operate normally in a high temperature environment. WayDun can integrate heat sinks for the conductive slip rings of ship cranes operating in high-temperature environments. And naturally can also integrate heaters for the conductive slip rings of offshore cranes operating in low-temperature cold areas. The working principle of the heater is the same as that of the heat sink, and it is also controlled by the thermostat.
However, temperature control equipment generally uses a lower voltage and its power is generally taken from the inside of the conductive slip ring. Therefore, in most cases, offshore cranes products that integrate strong and weak electricity. Its strong current module is responsible for powering the crane steel cable receivable and discharge motor, and the weak current module is used to transmit signals and power the temperature control equipment inside the conductive slip ring and other auxiliary equipment on the crane.
WayDun manufacturer has the ability to develop high-current slip rings with a single-channel current transmission capacity of 3000A. Also have the ability to produce slip rings or central collectors with multiple functions for use in multiple industries. Professional slip ring manufacturer can provide customer customization based on technical conditions. Such as integrating other different modules, smaller current modules, weak current signal modules, optical signal modules, etc.
For example, in different high-risk operation scenarios such as petrochemical mining and exploration, different levels of protection are required. Highest IP66 protection level can be designed for customers. Of course, in addition to design, material selection is also very important. Products in different operation scenarios have different shell materials.
