Product Description

Specification

PS Series Hydraulic Disc Brake System is mainly used for drilling rigs, workover rigs and well hoisters.

The system consists of three parts: brake actuation mechanism, hydrualic station and operation panel. These three parts are connected through hydraulic pipes. The hydraulic station supply hydraulic power for the system; the control panel controls the hydraulic power, it is make up of service brake assembly, parking brake assembly, emergency brake assembly and all kinds of pressure indicators; The actuation mechanism is a braking actuation unit which consists of braking caliper, caliper frame and friction disc. The braking caliper has two parts, one is normal open service calipers, the other is normal closed safety calipers. Its main function is to brake the drum so that the speed to raise or lower the drilling tools can be adjusted.

Function

Parts Description	Function
Service Brake	Adjust the pressure which the service caliper press on the friction disc through pulling service brake handle to provide adjustable braking torque to the rig. It can meet the requirements of different working conditions, such as bit feeding ,tripping etc.
Emergency Brake	Press the Red emergency brake button when emergency occur, then the service calipers and safety calipers will all brake.
Over-winding Protection	If the service caliper fail to brake because of wrong operation or any other reason when the load is lifted to a certain height, the over winding or colliding prevention valve will send a signal to the emergency valve, then the service calipers and safety calipers will brake at the same time to prevent crown block accident.
Parking Brake	Pull the parking brake handle down when the drilling rig will stop working or the driller wants to leave, then safety calipers will brake to prevent the hook from sliding.
Power-off protection	Safety caliper will brake automatically. At the same time, the energy stored in the accumulator will provide brake power to handle emergency situation, service caliper can brake 4-6 times at normal conditions, sometimes 12 times or so.
