Design Features of mechanical drawworks
All bearings are roller bearings. Shafts of drawworks are made of alloy steel.
Chains with forced lubrication can transmit with high accuracy and high strength.
Drum of drawworks is grooved. Ventilating air clutches constitute the high and low speed ends.
Brake drum (brake disc) is forcedly cooled with circulating water.
Drawworks surface is intermediate-frequency quenching-treated, and is durable.
Tooth profile of sprocket is intermediate-frequency quenching-treated. Involute-spline-tooth type clutch is used as shifting clutch.
Main brake is band brake or disk brake, auxiliary brake is Electromagnetic eddy current brake (water-cooled or air-cooled).
Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements.
