Rolls-Royce Ulstein-UMAS V Marine Automation UN925 Panel Controller Roller for Parts

Product Relevance and Positioning

The UN925 Panel Controller is an integral part of the Rolls-Royce Marine Automation System, designed for the complex operating environment of a ship, and is designed to provide the crew with an efficient and precise experience of equipment control and system monitoring. As the direct medium of human-machine interaction, the wheel is at the centre of convenience and functionality. It should not only meet the durability needs of the crew to operate frequently during the ship navigation, but also ensure the accuracy and timeliness of the operation feedback to cope with all kinds of emergencies and fine control tasks in marine operations.

Roller Specifications

Mechanical structure: High-precision ball bearing design ensures that the roller is smooth and fluid in the rotation process with minimal resistance. The diameter of the roller has been carefully considered and set to [X] mm, which ensures sufficient friction during operation for precise control by the crew, and will not take up too much panel space due to oversize or cause inconvenient operation due to undersize. The surface of the roller is treated with a special texture to increase the friction between the fingers and the roller, which makes it easy to operate and avoids slipping even when the crew has wet hands or is wearing gloves.

Electrical Performance: The rollers have built-in precision potentiometers or encoders for converting physical rotational movements into precise electrical signals. Potentiometers provide a continuously variable resistance output, which, in conjunction with the controller's internal circuitry, enables linear adjustment of relevant equipment parameters, such as adjusting the speed of the ship's propeller, the angle of the rudder, and so on. The encoder is more precise and can convert the rotational position of the wheel into a digital signal with very high resolution, usually up to [X] pulses per revolution, which enables the system to recognise and respond to operations with extreme accuracy and meet the stringent requirements of ship automation systems for high-precision control.

Environmental Adaptability: Given the complexity of the ship's operating environment, the tumbler must have excellent environmental adaptability. It is able to operate in extreme temperatures ranging from - 20°C to + 60°C. Whether in cold polar waters or hot tropical waters, the performance will not be affected by temperature problems. In terms of humidity, it can withstand up to 95% relative humidity, effectively preventing short circuits or mechanical parts from rusting due to humid air. In addition, the roller also has good anti-vibration and anti-impact performance, can withstand the ship sailing process due to the impact of waves, equipment operation and other severe vibration and impact, to ensure stable operation in a variety of harsh sea conditions.

Performance Advantages

Convenience and efficiency of operation: the design of the wheel takes full account of ergonomics, and its position and shape make it easy for the crew to operate the panel naturally with their fingers or palms for scrolling operation. Compared with the traditional push-button operation, the wheel can achieve faster and more continuous parameter adjustment. For example, when adjusting the power output of the ship's power system, by quickly rolling the wheel, the crew can adjust the power value to the desired range in a short period of time, which greatly improves the operation efficiency and reduces the operation time, which is especially important in emergencies (e.g., when the ship needs to quickly avoid obstacles or deal with sudden wind and waves).

Precise control ability: Due to its high-precision electrical components and mechanical structure, the roller is able to realise extremely precise equipment control. In ship automation system, the precise control of all kinds of equipment is related to navigation safety and operational efficiency. Take the dynamic positioning system of the ship as an example, through the roller of UN925 panel controller, the crew can precisely adjust the position and attitude of the ship, and the error can be controlled within a very small range, which ensures that the ship maintains a stable operating position under complicated sea conditions, and meets the needs of offshore drilling platform supply, underwater engineering operations and other tasks that require extremely high precision of the ship's positioning.

Durability and Reliability: Adopting high quality materials and advanced manufacturing process, the roller has excellent durability and reliability. During the long-term operation of the ship, the roller may be subjected to frequent operations and harsh environment, but due to its robust mechanical structure and high-quality electrical components, it is able to withstand a large number of operating cycles without failure. After rigorous laboratory testing and actual ship application verification, the roller's average number of trouble-free operations can reach more than [X] times, which greatly reduces equipment maintenance costs and the risk of system downtime due to roller failures, and ensures the continuous and stable operation of ship automation systems.
