Main hydraulic system: high pressure electric control open-circuit system, compared to closed-circuit system, there is no pressure difference loss caused by oil-adding pressure, the system is more energy saving, environmental protection, rig work ability further enhanced.
Equipped with two diesel engines, one or two engines working is realized to meet different conditions, and thus saving energy. If one of the twin engines breaks down, the other one can still be operated normally (same force. Lower speed), greatly improve construction safety.
Driving head rotation and push&pull velocity adopt proportional linear stepless regulation.
Front and back clamping can be separated, clamping floated in whole process.
Floating spindle is in favor of protecting drill pipe thread.
Floating girder is easy to loading, unloading, climbing and transportation, convenient for adjusting entry angle, which can effectively protect clamps.
Wide steel walking track is convenient for loading and unloading without taking apart, directly in position.
Twin seat in operation cab, spacious and comfortable, can lift, rotatable and with open field of vision.
Drill pipe centralizer in the middle increases accuracy of drill pipe loading and unloading , highly improving work efficiency.
Main control valve: according to rig construction conditions, self design, with patent protection main switch valve; simpe and reliable structure, ensure smooth operation. Big drift diameter design, with smaller throttling loss, smaller heating power, more energy saving, compact shape etc.; more reasonable power system structure, improve push-pull speed on the condition of not affecting rig torque and push-pull force, hence meeting speed demand in different construction condition.
To enhance the executing mechanismability , hydraulic system is designed in conformity to large flow and high pressure. Our self-designed inserting control valve group reacts fast and reduces 50% pressure loss in hydraulic system.
Self-designed and developed,combined electronic controlling system realizes its adaptive control to different working condition and different geologic strata，improving the efficiency of construction 30%.
Liquid crystal system man and rig exchange can monitor rig condition any time, which can adjust rig work, alarm parameter, making operation simpler and more confortable.
Rational and effective cooling system ensures safety, reliability and efficiency of system, and extends motor using life, avoiding motor damages.
System is configured with both auto-operation and man-operation. Auto-operation could timely adjust the running parameter according to the strata situation and automatically adjust the rig for rig and drill rod protection.
