Embodiment Construction

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0029] like Figure 1-3 As shown, the present invention is an inner passive type fully automatic anti-bias wear oil pipe rotator, comprising a base 1 with a through cavity 11 formed inside, the through cavity 11 fixing the oil sucking pipe through the suspension seat, and the oil sucking pipe is provided with The oil sucking polished rod 4 that moves up and down provides the power required for the rotation of the oil pipe through the oil sucking polished rod 4 that moves up and down. The built-in passive transmission mechanism includes a damper assembly, a connecting rod assembly and a transmission assembly. The damper assembly is fixed on the oil sucking rod 4 by screws, and t...

Abstract

The invention discloses a built-in passive full-automatic anti-eccentric-wear oil pipe rotating device. The built-in passive full-automatic anti-eccentric-wear oil pipe rotating device comprises a base, wherein a through cavity is formed in the base, the communicating cavity is fixed to an oil pumping pipe through a hangoff receptacle, and a smooth sucker rod moving up and down is used for providing power required for the rotation of an oil pipe inside the oil pumping pipe. The built-in passive full-automatic anti-eccentric-wear tubing swivel is characterized in that a built-in passive transmission mechanism is arranged between the smooth sucker rod and the hangoff receptacle, and the built-in passive transmission mechanism comprises a damper assembly, a connecting rod assembly and a transmission assembly. According to the built-in passive full-automatic anti-eccentric-wear oil pipe rotating device, the problems existing in the prior art can be solved, the problem of eccentric wear ofthe oil pumping pipe can be solved by adopting a built-in passive structure, and the service life is prolonged.

Description

technical field [0001] The invention relates to an inner passive type fully automatic anti-eccentric wear oil pipe rotator. Background technique [0002] The eccentric wear of the sucking pipe of the oil well leads to the wear-through failure of the oil pipe, which is a serious problem in oil production. Every year, due to the wear and tear of the oil pipe, the scheduled production maintenance is caused, and the loss of the replacement of the oil pipe is huge. In the 1980s, the anti-eccentric wear solution proposed by American R&M Energy fundamentally solved this problem. The anti-eccentric wear device has also become a standard configuration for oil wells abroad, but it is basically not equipped in my country and can only be purchased from abroad. In addition, the anti-eccentric wear device of R&M Energy uses external power to drive the oil pipe to rotate at a very low speed. The overall structure is complex, the manufacturing is cumbersome, and the cost is high. Therefore...
