Abstract
The utility model relates to a hydraulic oil pumping machine without walking beams. A pulley wheel is arranged on the top of a side straight supporting frame on a base. One side of a straight leg is provided with two hydraulic cylinders, and the top end of the straight leg is provided with a lifting pull rod. One side face of the lifting pull rod is provided with a transverse pressing rod, and two top ends are connected by a lifting pull transverse rod. The sides of the hydraulic cylinders are connected with reversing valves, and the top ends of the reversing valves are provided with control rods. A motor at a far distance is connected with an oil pump. The utility model is formed by that an oil outlet and an oil inlet on one side of each of the reversing valves, and an oil inlet and an oil outlet on the other side of each of the reversing valves are respectively connected with oil inlets and oil outlets of the two hydraulic cylinders, and an oil inlet and an oil outlet of the oil pump. The utility model has the advantages of small size, light weight, simple structure, energy saving, easy fabrication, convenient repair and maintenance, and easy popularization.
Description
The utility model relates to and is used for the hydraulic type non-beam beam-pumping unit.
The utility model improves development and comes on public conventional beam-pumping unit basis.
Current, public conventional pumping unit, bulky, complex structure, energy consumption is big, and the maintenance difficulty weighs owing to walking beam is long, adds equilibrium block, the walking beam horse head very easily produces run-out tolerance at the volley, and the power transmission crank easily produces price scissors, causes the polished rod accident to increase, and directly the influence oil pumping is produced.
The utility model purpose is for solving above existing problems, and designs a kind of new pumping unit, and its volume is little, and simple structure, is easily implemented efficient, low consumption.
The utility model technical solution is, on base (1), be provided with side allotment support (2), there is pulley (3) on the top, the straight leg one of side allotment support (2) is surveyed, and two oil hydraulic cylinders (4) are arranged, and there is lifting rod (5) on the top, wherein a side connects horizontal depression bar (6), and two tops lift cross bar (7) and link to each other.This oil hydraulic cylinder (4) side is connected with selector valve (8), and there is controlling rod (10) on its top.The distally has motor (12) to link to each other with oil pump (11).With high-pressure oil pipe (9), selector valve (8) one side oil outlets, filler opening, opposite side filler opening, oil outlet, respectively with two oil hydraulic cylinders (4) filler opening, oil outlet, oil pump (11) oil outlet, the filler opening formation that is connected.
The utility model advantage is, owing to replaced the conventional pumping unit transmission device with Hydraulic Power Transmission System, has omitted walking beam horse head and crank, so fundamentally solved the horse head run-out tolerance, the crank price scissors.Its volume is little, and is in light weight, and performance is good, and energy-conservation, consumption reduction, simple structure, easy-maintaining maintenance, cheap operate steadily and efficient, are convenient to implement to promote.
Following accompanying drawing has been described embodiment of the utility model.
Fig. 1 is the utility model structure front view.
Fig. 2 is the utility model structure right elevation.
The utility model specifically can be implemented like this, and according to well depth, design and manufacture oil pumping type size is manufactured side allotment support (2), and is installed on the base (1), and pulley (3) is installed on the top.In straight leg one side of supporting frame, public two oil hydraulic cylinders (4) vertically are installed, distance determines according to the oil well diameter between the two.On lifting rod (5) is arranged, a rod end side is connected with horizontal depression bar (6), two tops connect with lifting cross bar (7).The oil hydraulic cylinder (4) that horizontal depression bar (6) are arranged, the side connects selector valve (8), and controlling rod (10) is equipped with on its top.The distally is equipped with motor (12), and it is linked to each other with oil pump (11).With high-pressure oil pipe (9), selector valve (8) one side oil outlets, filler opening, opposite side filler opening, oil outlet, successively respectively with two oil hydraulic cylinders (4) filler opening, oil outlet, oil pump (11) oil outlet, filler opening link to each other.Manufacture equilibrium block (17),,, lift cross bar (7) with two oil hydraulic cylinders (4) top and be connected around pulley (3) with wire sling (16).With mounted pumping unit, be installed on the pumping well, make its oil hydraulic cylinder (4), be positioned at well head (13) both sides, the interior oil pumping polish rod of oil pipe (14) (15) is fixed on the polished rod slips lifts cross bar (7) centre, implement to finish.Because structure tube, volume are little, in light weight, so move installation when being convenient to well workover.
The concrete operation like this of the utility model, work as energising, motor (12) drives oil pump (11), through high-pressure oil pipe (9), hydraulic oil is crossed selector valve (8), enter chamber under the oil hydraulic cylinder (4), promote internal piston, make lifting rod (5) promote to lift cross bar (7), drive oil pumping polish rod (15) rising oil pumping, when running to peak, promote the piston band and press hydraulic oil, from oil hydraulic cylinder (4) top drain tap, enter in the selector valve (8), push lever (10) spurs its piston and rises, and opens return opening, at this moment, under the sucker rod action of gravity, lift cross bar (7), press lifting rod (5) to descend, the chamber hydraulic oil flow is through selector valve (8) dump pump (11) under the oil hydraulic cylinder (4).Horizontal immediately depression bar (6) also descends, and presses controlling rod (10), promotes descent of piston, closes return opening in the selector valve (8).According to this, hydraulic oil follows back back and forth, promotes the middle piston of oil hydraulic cylinder (4) and moves up and down, drives polished rod (15) motion oil pumping.
