Drawworks Drill Rig Accessory - China

With more than more years experience in designing and manufacturing

drawworks, our company can design and manufacture 280-6000HP drawworks

for 1000m ~ 12000m various types of land and offshore drilling,

workover rig.

1 - Mechanically driven drawworks (B Series drawworks) Mechanical drive drawworks mainly takes diesel engine as prime mover, through the transmission assembly supplying power for the drawworks.

CNPC can produce 280HP ~ 2000HP different structural forms mechanical drive drawworks

2 - DC motor drive drawworks(D series) This type drawworks powered by DC motor improves the drilling efficiency of rig for DC motor speed can be regulated.

It has features as structure simple, small size and light weight.

CNPC can produce 300 ~ 3000HP series DC motor-driven drawworks.

3 - AC variable frequency electric driven drawworks (dB series drawworks) The single drum shaft and gear drive drawworks features small size, light weight, little vibration, low noise, high efficiency and long life, which especially meet the requirement of offshore rigs and high-power electric drive onshore rigs.

It is one of the ways to further enhance the effective level of technology for the electric drive drilling rigs.

Jianxin Petroleum can supply all series single shaft gear drive drawworks under 6000HP.

Product Features:

1 - Mechanical drive drawworks (B Series drawworks)

Bearings adopt roller bearing totally, shaft materials adopt high-quality alloy steel.

Drawworks adopt roller chain roll transmission to realize forward gear and adopt gear transmission to realize reverse.

All the chains are forced lubrication.

The drum is grooved, and the high-speed and low-speed ends of the drum shaft are equipped with ventilated-type air tube clutches.

The brake rim uses circulation water to force cool.

Band or disc brake is used in main brake.

Auxiliary brake is furnished with Regenerating brake, electromagnetic eddy current brake or air congtroled disc brake.

2 - DC motor drive drawworks(D series)

The drawworks adopt wall type and fully enclosed structure, and adopt internal gear shift mode through roller chain drive.

The drum is grooved, and the high-speed and low-speed ends of the drum shaft are equipped with ventilated-type air tube clutches.

The brake rim is cooled by circulation water.

Main brake adopts with a disc brake or hydraulic brake, Auxiliary brake is furnished with regenerating brake, electromagnetic eddy current brake or pneumatic drive and water-cooled disk brake.

3 - AC variable frequency electric driven drawworks (dB series drawworks)

Drawworks consists of AC variable-frequency motor, gear box, hydraulic disc brake, drawworks frame, drum shaft Assay and automatic-drilling system, etc; Gear transmission efficiency is high.

The drawworks is single grooved drum in structure.

Compared with similar products, it features simple structure, small volume and light weight.

Drawworks is driven by AC variable-frequency motor to realize stepless speed regulation, thus have big power, wider range in speed regulation.

The drawworks adopt hydraulic disc brake and regenerating brake and adopt with independent motor automatic-drilling.

B Series drawworks
