In the process of drilling well, for meeting different hoisting speed needs, driller can make dish brake traveling system hovering.The motor speed of winch is adjusted to 0, open input shaft and be used to the switch of stopping, allow the driving system of winch stop, open again Gear-shift switch, make backset cylinder discharge gear, then operate Gear Select Switch gear shift, move to after gear, close shift switch, make gear locked, whether the demonstration of observing backset pressure equates with bleed pressure.If equal gear shift success, otherwise, need to again operate.
(4) the input shaft control of being used to stop
After winch motor is shut down, prevent that winch is because inertia is rotated further, driller opens input shaft inertia brake switch, and input shaft is used to brake/clutch and is inflated rapidly brake, driving system stall.
Start before winch motor, must close and be used to the switch of stopping, make power-transfer clutch venting discharge brake.
(5) air pressure horn control
When driller need to contact and warn with the driller of rig floor or machine room, can be by pressing air pressure horn button, loudspeaker pipe, and send signal.
(6) pneumatic spinner control
In round trip, while if desired making up a joint, driller can open pneumatic spinner master cock handle to position on the buckle, button function in realization.
Note: generally do not allow to operate pneumatic shackle function.If there is special situation, can use pneumatic shackle function, but driller must be according to the requirement operation of oil drilling, in case down-hole equipment is laid down the possibility in well.
(7) other
On driller's Pneumatic controlled box, be furnished with bailing drum switch in order to control the running of bailing drum and to stop,
8, Eton brake
The assist brake that Eton brake 21 is winch.
9, sand brake
Sand brake is the brake equipment of bailing drum axle 11, is mainly made up of parts such as brake strap, bearing seat, brake levers.
This mechanism is simple lever band brake 25.Be passed to brake strap active end by leverage, drive brake strap to embrace brake hubs, reach the object of brake.
