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) Bearings adopt roller bearing totally, shaft materials adopt high-quality alloy steel. The drawworks adopt wall type and fully enclosed structure, and adopt internal gear shift mode through roller chain drive. 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 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. |
