Hydraulic Complete Disk Brake
Composition and functions of the product
PSK series Hydraulic disc brake is composed of four parts:
1. Brake execute unit
2. Hydraulic power unit
3. Operating control device
4.Connecting lines and cables
PSK series hydraulic disc brake can be used for different
kinds of braking required for operations of drilling and workover
rigs.
1. Service braking: control braking force through handle and
realize drill bit feeding and tripping of different brake torques
in
drilling/workover operation.
2. Parking braking: temporary parking braking for drilling
and workover rigs and meet the weight demand for suspending the
largest drilling rig.
3.Emergency braking: emergency braking of drilling and workover
rigs
4.Accumulator braking: emergency braking of drilling and
workover rigs in a short time in case of unexpected failure of
hydraulic power supply.
5. Protection braking: various types of protection braking
such as over-wind anti-collision, anti-smashing, power failure, gas
interruption and loss of pressure through
electro-hydraulic-pneumatic sianal.
Product features
1. Brake caliper has the strongest braking capacity among products
of the same type in China, enjoys sufficient braking reserve
coefficient
and reliable braking performance.
2.There are various clearance adjustments methods for
users’selection. such as hydraulic adjustment. fat injection
adjustment. thread
mechanical adustment and hvdraulic automatic compensationf is
throuah these methods that brake interval can be reaulated
convenientlv
quickly and accurately.
3. Brake caliper. with small overall dimensions. can be installed
and maintained simply: brake block can be replaced conveniently.
4. Optimized brakina control curve and hiah control accuracy can
realize remote automatic control.
5. PSK series brake caliper. which is serialized and standardized.
can meet various demands of drilling and workover rigs in multiple
workino
conditions such as and. ocean. desert and low temperature.
6.There are various brake discs, e.g. air cooling type. water
cooling type and strong cooling type. applicable to different
drilling conditions.
7. There are various types of hydraulic power unit; the
configuration can meet the combined hydraulic power supply required
for disc brake
drilling rig and other equipment.
8. The tailor-made brake block. with excellent friction
performance, can be replaced conveniently.
9. Dominant elements of system are purchased around the world.
which ensures the reliability of eauipment.
