Drill pipe spinner is applicable to drill pipes and drill collars of 2-3/8 -7 in. It is mainly composed of two syinmetrical components, each of which drives the gear transmission through air motor and drives the wheel rotation. Operate the air valve with air spring to make the wheel compress the drill pipe: control the air motor valve handle, and start the left and right motors. The motors drive respective drive wheel through left and right reduction units. Due to the friction torque, (he drill pipe rotates, and the pipe screw thread rotates in or out. I lie opening of wrench can adapt pipes of dirferent diameters through adjustment without need for exchange of wheel, which makes manufacturing, application and maintenance more convenient. The Drill pipe spinner is a kind of wheel-type spinning tool. Compared with traditional chain wrench, the Drill pipe spinner boasts the advantages of large speed, no slippery and no damage to drill pipe, and can be used in oil and mud environment, with the advantages of safety and reliability.
The brake torque of the Drill pipe spinner is 1100ft-lbs (1490 N *m), and the in and out spinning speeds are large. During Ihe tripping operation. The Drill pipe spinner substitutes the spinning rope (spinning chainh so as to make Ihe spinning operation safe and reliable, reduce the labor intensity of drillers, and promote the tripping speed. The air motor in the spinner can rotate clockwise and anticlockwise, which makes coring and treatment of drilling troubles mon, convenient.
