These systems consist of an interconnected network of hydraulic devices that intelligently control the position and orientation of railway switches. Each switch is equipped with hydraulic servoactuator that allow real-time adjustment to ensure a smooth and safe passage for trains. The use of closed-loop hydraulic technology enables much more precise control compared to traditional mechanical systems.
The basic operation of a closed-loop hydraulic multipoint railway switch system can be summarized as follows:
- Built-in position Transducer: it detects the current position of the railway switch and communicates this data to a centralized control system.
- Proportional Valve: the control system uses this information to adjust the hydraulic pressure in the actuators connected to the railway switch, maintaining it in the desired position.
- Hydraulic Actuator: controlled by the proportional valve, it moves the railway switch to the correct position and provides real-time position feedback throughout its travel, enabling precise positioning.
- Real-Time Monitoring: during the passage of a train, the transducersconstantly monitor the position of the railway switch to ensure a safe and seamless passage.
