MECHAN-ELECTRIC OIL DRILLING RIGS
1. This kind of rig is available in four models
1000HP(ZJ40/2250LDB) 1500HP (ZJ50/3150JD)
Notes: L—Chain Compound Transmission J — Narrow V-belt Compound Transmission DB—Rotary table is driven by VFD
2. Power: three-(or four)-diesel-engine (2000 or 3000 series) linkages, which are connected with couplers and reducer casings.
3. The drawworks and the mud pump are mechanically driven. The rotary table is independently driven by an AC/DC variable frequency motor.
4. Easy installation and better sealing as a result of taking an integral chain box or V-belt compound transmission unit.
5. The drawworks is equipped with the grooved drum and shifting a gear for it is carried out by air cylinders. The hydraulic disc brake is regarded as main brake and the eddy current brake as auxiliary brake.
6. The rotary table is driven independently by AC variable frequency motor and can accomplish stepless speed regulation with 0~210r/min. AC is supplied by an auxiliary generator set.
7. Main mechanical parts are manufactured in conformity with API Spec and applied API monogram on them.
