GK 200 Borehole Drilling Rig Main Features
1.Engine:Feed by hydraulic cylinder,the drilling efficiency is higher and it can save labor.
2.Drill rod:53x59 drilling rod adopted,high rigidity and strong delivery torque.
3.Spindle:Vertical spindle are fixed by four groups of bearing to ensure that the rotary machine is rigid
enough for gravel layer and other complex geoloical conditions.
4.Mud pump:Equip mud pump with flow 160L/min,save cost and also make the structure compact.
5.Concentrated handle, small footprint,light weight, strong decomposition, easy to move.
Common faults and maintenance methods of drilling rig:
Fault 1: The pressure of the hydraulic system of the drilling rig is insufficient, and the pressure regulating valve is tired. The limit nut shall be adjusted or the spring shall be replaced.
Fault 2: The drilling rig coupling is hot and the elastic ring is excessively worn; The reason is that the coaxiality between the drill power machine and the clutch is poor, and the assembly coaxiality needs to be improved;
Fault 3. If the oil pump of the drilling rig does not fill or the oil quantity is insufficient after starting, first check the oil quantity in the oil tank and fill it to the oil level line. If the fault is still not eliminated, check whether the filter is blocked. In addition, check whether the oil tank vent is blocked, or the oil suction pipe joint is loose and air intake and other reasons;
Fault 4. The holding brake of the winch of the drilling rig slips. The main reason is that there is oil dirt in the holding brake belt, which needs to be removed; If there is no oil stain, check the clearance between the brake belt and brake wheel, and properly tighten it if it is too loose;
Therefore, the operator is required to clean, maintain and maintain the drilling rig regularly, find the root cause of the problem in time and deal with it, so that the use time of the drilling rig will be longer.
