Core Components
- Electrical Control Unit: This is the brain of the system, comprising advanced microprocessors and control algorithms. It receives input signals from external sources such as programmable logic controllers (PLCs) or human - machine interfaces (HMIs). Based on these signals, it precisely regulates the electrical power supplied to the hydraulic components, enabling accurate control of the actuator's movement, speed, and position.
- Hydraulic Power Pack: The hydraulic power pack is responsible for generating and distributing hydraulic fluid under pressure. It includes an electric motor - driven pump that draws hydraulic fluid from a reservoir and pressurizes it. The pressurized fluid is then stored in an accumulator (if present) to ensure a stable and continuous supply of hydraulic power, even during peak demand periods. The power pack also incorporates filters to maintain the cleanliness of the hydraulic fluid, protecting the system from contamination - related failures.
- Electro - Hydraulic Actuator: This is the main executive component that converts hydraulic pressure into linear or rotary mechanical motion. It consists of a cylinder or a motor, depending on the type of motion required. The actuator is equipped with sensors, such as position sensors and pressure sensors, which continuously monitor its operational status and feed the data back to the electrical control unit. This closed - loop feedback mechanism allows for real - time adjustments and high - precision control.
