Abstract

The invention discloses a stroke automatic adjusting device of a beam-pumping unit. The stroke automatic adjusting device comprises a crank mechanism. The crank mechanism comprises a crank rod. A first supporting frame and a second supporting frame are arranged on the crank rod in a spaced mode. A moving weight box and a lead screw mechanism are arranged between the first supporting frame and the second supporting frame. The lead screw mechanism is used for driving the moving weight box to move left and right on the crank mechanism. The moving weight box is connected with a walking beam of the pumping unit. The lead screw mechanism is connected with a control cabinet for controlling the moving weight box to move left and right through the lead screw mechanism to realize automatic adjusting of the stroke of the pumping unit. According to the stroke automatic adjusting device, the structure is compact, installation is reliable, operation is easy, and the method that the stroke is adjusted through adjusting the position of a crank hole by people on site is replaced, so that automatic adjusting of the size of the stroke is achieved.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of oil production machinery, in particular to a device for automatically adjusting the stroke of a beam pumping unit. [0003] 【Background technique】 [0004] Oilfield blocks have many points and wide areas, inconvenient transportation, manual on-site stroke adjustment and stroke adjustment times, long operation cycle, high labor intensity, and poor timeliness of parameter adjustment. In order to ensure the coordination of oil well supply and drainage and improve the pump efficiency of oil wells, it is necessary to adjust oil wells in real time Swab parameter. [0005] At present, there is an intelligent adjustment device for stroke times. Due to the popularization and application of multi-speed motors for pumping units, the adjustment of stroke times has been simplified to order and can be completed within a few seconds by pressing the button. Position, to change the effective length of the crank o...
