Drawworks For Drilling Rig In Oilfield
Product Introduction
Design Features of mechanical drawworks
A: All bearings are roller bearings. Shafts of drawworks are made of alloy steel. B: Chains with forced lubrication can transmit with high accuracy and high strength. C: Drum of drawworks is grooved. Ventilating air clutches constitute the high and low speed ends. D: Brake drum (brake disc) is forcedly cooled with circulating water. E: Drawworks surface is intermediate-frequency quenching-treated, and is durable. F: Tooth profile of sprocket is intermediate-frequency quenching-treated. Involute-spline-tooth type clutch is used as shifting clutch. G: Main brake is band brake or disk brake, auxiliary brake is Electromagnetic eddy current brake (water-cooled or air-cooled).
