Rotary drilling rig is a kind of common failure. Recently, some customers have reflected that after using small rotary drilling rig for a period of time, the drilling rod stops after sliding for a certain distance when the operating handle is returned to the center position, and we usually call this phenomenon as slipping of the drilling rod. So how to solve the phenomenon after the drill pipe slips? Today, KAO will share with you a method of how to judge and eliminate the failure of drill pipe slipping, and hope to bring you help.

A: hydraulic lock failure may lead to slippage. At this time, you can adjust the lock cylinder of the hydraulic lock, if there is no effect in the removal of the inspection, do the loading test, the main winch and the vice winch hydraulic lock is the same, by and by replacement method to check the hydraulic lock.
Second: remove the two oil pipe through the solenoid valve removed and blocked with a mouth, in the operation of the main winch, if not useful, then in further inspection of other parts.
Third: check the brake to see if the brake piston moves smoothly.
Fourth: adjust the valve to adjust the oil volume of the signal oil, if the rotary drilling rig can not work properly, you have to check whether the brake signal oil tubing is clogged.
The above is summarized for you to rule out the rotary drilling rig drilling rod slipping method, if there are other methods, welcome to put forward, let's study together. I hope that this article can give the masters who encountered the drilling rod slip to provide a help.
