1.The drilling rig adopts advanced AC variable frequency drive mode.By 3 CAT3512A diesel generating units connected to power generation, the inverter rectifier inverter into variable frequency adjustable AC drive winch, mud pump, rotary motor.Variable frequency drive cabinet uses one to one way control, realizes the stepless speed regulation.
2.Drilling rig with the former open derrick, low installation, the overall rise.
3.The base is for singleshot structure, all equipment should be installed on low position and power integrated by hoisting winch.
4.The winch is overall single shaft gear transmission, by a 1100kW AC inverter motor drive.The main brake using hydraulic disc brake. Auxiliary brake uses motor energy consumption brake.Winch is equipped with automatic drilling and anti collision device.
5. The rotary table uses an independent drive, by a 600KW AC frequency conversion motor, through the chain box drive. The rotary speed is 0-220rpm range stepless speed regulation.
6.Each mud pump uses a 1000KW AC variable frequency motor driven by the joint narrow V belt.
The stepless speed regulation of AC frequency conversion motor can realize the continuous and stable change of pump and displacement.
7.Drilling rig uses 5 rate mud purification system, it can be very well to remove the harmful mud to achieve the mud purification.
