Product Details

A drawworks is the core component of the oil rig, mainly used to deliver tools, hoist/descend derricks and run the drilling tools and pipe shrouds into the well during the drilling process.

Technical Performance & Characteristics 

1,Electric single-axis winch:

It comprises an AC or DC motor, a gear reducer, a hydraulic brake pad, a frame, a roller shaft assembly, an automatic drilling tool feeder, control system, etc. Compared with those of the same type, it features less parts, smaller size, and lighter weight. The roller shaft is driven by a DC or AC variable frequency motor driven through thegear reducer (or by two motors driving the gear reducer) and can achieve smooth speed regulation from 0 to 140HZ. A two-stage gear reducer is incorporated to provide driving force, featuring high efficiency, reduced vibration and noise, and extendedservice life. The main brake is of hydraulic pad type, and the auxiliary adopts dynamic braking or EATON products. In the roller is provided with a LeBus rope groove, an independent numerically controlled AC variable frequency gearing and an automatic computer control system so as to automatically deliver rigs; the conditions when running tools to and drilling in the well are under real-time monitoring and analysis in order to achieve optimal performance.

2,DC-driven chain transmitting winches:
A DC motor is incorporated to provide driving force. Such drawworks are in split or one-piece structure. At both the high and the low speed ends of the roller, a ventilated air tube clutch is installed. The main brake is of hydraulic pad type and the auxiliary of electromagnetic eddy type. Gas gear shift and chain transmission are adopted. The chains and bearings are lubricated respectively by thin oil and grease. In the roller is provided with a LeBus rope groove so as to achieve automatic delivery of drilling tools.  
3, Mechanically driven winches:
At both the high and the low speed ends of the roller, a ventilated air tube clutch is installed. The rim of a brake (or a brake disc) is subject to forced cooling with circulating water and surface medium-frequency hardening, thus featuring satisfactory wear resistance and extended service life. The main brake is of hydraulic pad or band type, and the auxiliary adopts dynamic braking or EATON products (cooled by water or air). All gear shift clutches are provided with involutes and spline teeth and adopt cylinder or pneumatic tire clutch shift structure to ensure simple, easy and reliable stage changeover. In the roller is provided with a LeBus rope groove so as to achieve automatic delivery of drilling tools.
