Hydraulic Transmission Technical Parameters and Specifications
This device integrates real hydraulic components (Rexroth), various actuator modules, a relay control unit, and PLC programming and control technology. The hydraulic components are self-contained modules, each equipped with a base plate with spring-loaded pins. During training, various hydraulic system circuits can be assembled on a universal aluminum plate. The motor and pump are integrated with bearings and then fixed to the oil tank. An air cooler provides constant cooling. The oil tank and control panel are housed separately. The device features three-phase leakage protection, and the DC power supply has overcurrent protection. The system is rated for 6.3 MPa.
Main technical parameters
Input Power: Three-phase, five-wire, 380V, ±10% tolerance, 50Hz. A leakage protector provides the control panel with main power. A grid voltage meter monitors the grid voltage, with three indicator lights and an illuminated fuse. The control panel's power supply is controlled by a start/stop switch and includes leakage protection.
