Product IntroductionThe WF183 Constant Deceleration Hydraulic Station is an important safety and control component of mine hoists. Together with the disc brake and electrical control system, it forms the hydraulic braking system of the mine hoist.
The WF183 Constant Deceleration Hydraulic Station features constant deceleration control during emergency braking via the electrical control system, while retaining the original constant-torque two-stage braking performance. If the constant deceleration control system fails, it automatically switches to the constant-torque two-stage braking mode, enhancing system reliability.
Additionally, this hydraulic station uses a solenoid directional valve with spool position monitoring, allowing self-inspection during routine maintenance, significantly improving automation and providing reliable support for normal equipment operation.

ApplicationPerformance Features
1. Working Brake: Provides adjustable hydraulic pressure to the disc brake, allowing the hoist to achieve different braking torques for normal operation, speed regulation, and stopping.
2. Constant Deceleration Safety Brake (in-shaft): In any emergency within the shaft, automatically adjusts the disc brake pressure to decelerate the hoist at the set rate. After stopping, all disc brake pressure quickly returns to zero, placing the system in full braking mode.
3. Two-Stage Safety Brake (in-shaft): If constant deceleration fails, automatically switches to two-stage braking. Disc brake pressure drops to a preset value and, after a delay, returns to zero, ensuring full braking.
4. Level-One Safety Brake (at shaft top): In any emergency at the shaft top, disc brake pressure immediately returns to zero, putting the system in full braking.
5. Startup Self-Check: Before operation, the hydraulic station performs self-inspection to confirm proper function. If it cannot meet operational requirements, an alarm is triggered.
