Embodiment 3

[0025] Embodiment 3: as attached Figure 7 and 8 As shown, the single-cylinder two-way fully balanced hydraulic pumping unit includes a hydraulic device, the hydraulic device includes a hydraulic cylinder 12 and a hydraulic pump 13, the hydraulic cylinder 12 communicates with the hydraulic pump 13 through a hydraulic pipeline, and the hydraulic cylinder 12 includes a cylinder body , piston rod 1 and piston 3, this hydraulic cylinder 12 adopts two-way hydraulic cylinder, and balance box 14 is positioned at frame 15, and the top of frame 15 above balance box 15 is equipped with oil pumping fixed pulley 16, and the oil pumping platform 17 The inner end is installed on the upper outer side of the frame 15, the oil pumping guide wheel 18 is installed on the outside of the oil pumping platform 17, the inner end of the oil pumping rope 19 is fixedly installed on the balance box 14, and the outer end of the oil pumping rope 19 passes through the pumping The oil fixed pulley 16 and th...

Embodiment 1

[0032] Embodiment 1: as attached Figures 1 to 3 As shown, the difference from the above-mentioned multi-stage piston two-way hydraulic cylinder is that the cylinder body of embodiment 1 includes a fixed cylinder body 2 and a movable cylinder body, and only one level of movable cylinder body is the final movable cylinder body 6, while the final stage movable cylinder body The lower end of the cylinder body 6 is fixed together or integrated with the piston 3 in the fixed cylinder body 2 with its next-level movable cylinder body, and an upward oil passage hole 7 is arranged on the piston 3 to communicate with the upward chamber 4 of the upper and lower cylinder bodies. Its working process is as follows: when the piston rod 1 needs to move upward, high-pressure fluid is injected into the upward cavity 4 through the upward lubricating oil line 9, while the reverse oil line 10 is in the state of discharging high-pressure fluid outward, so that the fixed cylinder 2 Both the piston 3...

Embodiment 2

[0033] Embodiment 2: as attached Figures 1 to 6 Shown, the difference with embodiment 1 is: as attached Figures 4 to 6 As shown, the cylinder body of embodiment 2 comprises fixed cylinder body 2 and secondary movable cylinder body, and this secondary movable cylinder body comprises middle-level movable cylinder body 11 and final stage movable cylinder body 6; The piston 3 in the next-level movable cylinder, that is, the intermediate movable cylinder 11, is fixed together or integrated and has an upward oil passage hole 7 on the piston 3 to communicate with the ascending cavity 4 of the upper and lower cylinders; The lower end and the lower movable cylinder, namely the piston 3 in the fixed cylinder 2, are fixed together or integrated and have an upward oil passage hole 7 on the piston 3 to communicate with the upward cavity 4 of the upper and lower cylinders. Its working process is as follows: when the piston rod 1 needs to move upward, high-pressure fluid is injected into ...

Abstract

The invention discloses a single-cylinder bidirectional full-balanced hydraulic oil extractor. A balance box of the oil extractor is positioned in a stand; the inner end of an oil extracting rope is fixedly arranged on the balance box; the outer end of the oil extracting rope passes through an oil extracting fixed pulley and an oil extracting guide wheel and then can be fixedly connected with an oil extracting rod; a drawing movable block is arranged at the top end of a piston rod and is provided with not less three rope grooves; and the balance box vertically moves along the inside of the stand through the drawing movable block, an upper drawing rope and a lower drawing rope which are arranged at the top end of the piston rod. The invention has the advantages of reasonable and compact structure, favorable integral balance for drawing and oil extraction, long service life, convenient use, favorable installation performance, low energy consumption, low maintenance cost and the like. The invention has uniform force application on the whole and the lower drawing rope and the upper drawing rope are preferably more strands, so that the diameter of each strand of rope is reduced and the flexibility of the ropes can be improved under the condition of the same load; and meanwhile, the force application of each rope can be reduced and the service life of the ropes and the reliability of the system can be improved.

Description

1. Technical field [0001] The invention relates to the technical field of oil pumping units, and relates to a single-cylinder bidirectional fully balanced hydraulic pumping unit. 2. Background technology [0002] Existing pumping units generally include beam pumping units and hydraulic pumping units, etc., and beam pumping units are more traditional pumping units, but there are always the following problems: relatively large structure, relatively large weight, It is difficult to adjust the stroke, stroke times and balance, especially the high energy consumption; the hydraulic pumping unit is a new type of pumping unit that has appeared in the past ten years, but due to its complex structure, short service life, inconvenient use, and maintenance costs High and has not been widely used. 3. Contents of the invention [0003] The present invention provides a single-cylinder two-way fully balanced hydraulic pumping unit, which overcomes the deficiencies of the prior art and so...
