Description PSK series hydraulic control hydraulic disc brake is composed of three sections: brake execute unit, hydraulic power source and control unit. Brake execute unit is connected with hydraul
8、ic power source by hydraulic lines, and control unit is connected with hydraulic power source by hydraulic lines, too. Hydraulic power source provides necessary power for brake execute unit; brake execute unit is the executor of braking and consists of brake calipers, caliper support arms and brake
9、discs, where brake calipers is combined by main service calipers and emergency calipers as required; control unit is the control link of the installation and it controls the operating valves in control desk and realizes the action control of the brake execute unit. PSK series hydraulic control hydra
10、ulic disc brake has the following five functions: 1. Service brake: adjust the positive pressure of the main service caliper on brake disc by operating the control handle of the service brake, as a consequence provide adjustable braking torque for drawworks and meet different operating condition req
11、uirements such as normal drilling, trip, etc. 2. Parking brake: when drilling rigs dont work or drilling worker leaves control desk temporarily, turn on the parking brake to braking position, so emergency calipers brake the drawworks to prevent rotary hook from slipping down. 3. Emergency brake: in
12、case of emergency, press down emergency brake button, then both main service calipers and emergency calipers brake the drawworks. 4. Over winding/crown-block protecting: when the rotary hook raises to a position with heavy goods, the service brake fails to brake the drawworks due to operational erro
13、r or other reasons, the crown-block protecting system gives signal, then both main service calipers and emergency calipers brake the drawworks. 5. Air failure automatic brake: under the condition of air failure of the brake system, the emergency brake brakes automatically to prevent any accidents fr
