Hydraulic station is a hydraulic source device composed of hydraulic pump, drive motor, fuel tank, directional valve, throttle valve, overflow valve, etc., or a hydraulic device including control valve.Supply oil according to the flow direction, pressure and flow required by the driving device, it is suitable for all kinds of machines separated from the driving device and the hydraulic station. Connect the hydraulic station and the driving device (cylinder or motor) with tubing, and the hydraulic system can realize all kinds of prescribed actions.
Characteristics of constant deceleration hydraulic system
1.The constant deceleration hydraulic system adopts a completely independent dual-tank dual-station type, one for one and one for standby. When a certain station is completely unable to be put into use, the electrical control and hydraulic control can be switched to another station Continue to maintain system work and carry out non-stop repair and maintenance work.
2. Applicable to multi-rope, single-rope, single-cylinder, double-cylinder (with adjusting rope) hoist.
3. On the multi-rope friction hoist, each station can use three-channel redundancy technology. When constant deceleration and safe braking are performed, once a channel fails, the hydraulic system combines the closed-loop adjustment function of the electrical control system. It still maintains its constant deceleration braking to ensure that the constant deceleration function can be implemented smoothly in the event of a fault.
4. With independent working brake and safety brake control circuit, the constant deceleration safety brake actuator adopts a reliable and no-wait design concept, so that the constant deceleration safety brake has no time and space gaps, and further increases the safety brake reliability .
