AC VFD Electric Drilling Rig ISO & API

1. Adopting advanced fully digital AC variable frequency technology , the intelligentized driller control is realized through the integrated design of PLC, touch screen , pneumatic, electric, hydraulic and drilling instrument.

2. Drawworks, ratory table, and mud pump are driven by wide frequency, high power motor. Thereby the stepless speed regulation is reached.

3. Drawworks is single shaft gear drive drawworks with 2 gear, compact size, light weight, little vibration, low noise, high efficiency anbd long service life and adpot the compund mode with hydraulic disc brake and motor dynamic brake.

4. Automatic drilling is obtain \ed by drawworks main motor or auxiliary motor. 

5. Adopting intelligenzed soft starter, ET200 or ASI module to protect and supervise the MCC system.

6 .Protective functions including loss pressure of pneumatic or hydraumatic, the fault of electrical control system or motor, the limit of rotary table torque or pump pressure is provided.
