Abstract
The present invention relates to an energy saving oil pumping machine, which is characterized in that the energy saving oil pumping machine comprises a machine frame, guide slide ways, an orientation slide plate, two pulleys, steel cables, a balance weight block, a sucker rod, an electric speed reducer, a driving shaft, chain wheels, duplex chain wheels, an outer chain wheel and bridging shafts, wherein the guide slide ways are arranged on both sides of the inner part of the machine frame; the orientation slide plate with guide wheels is matched with the guide slide ways, and the two pulleys are arranged on the machine frame, and the steel cables are respectively connected the upper end and the lower end of the orientation slide plate; the steel cable on the upper end of the orientation slide plate contacts the two pulleys, and is connected with the balance weight block; the steel cable on the lower end of the orientation slide plate is connected with the sucker rod; then, a reciprocating lifting oil pumping mechanism is formed. The driving shaft which is connected with the electric speed reducer is arranged on the machine frame, and the chain wheels are respectively fixed on both ends of the driving shaft, and are respectively connected the duplex chain wheels through chains. The two duplex chain wheels are respectively connected with another chain wheel through the chains, and the bridging shafts are fixed on the two chains. The pulleys which are matched with a notch of the orientation slide plate are arranged on the bridging shafts to form a driver. The present invention has the advantages of long stroke of the sucker rod, high oil pumping rate, compact structure, small size, light weight, electric energy saving and low manufacturing and operation cost, and can be used for pumping water or used as power sources of other machines.
Description
Technical field
The present invention is a kind of pumping unit that relates to oil producing operation machinery.
Background technique
The pumping unit that existing oil producing operation is used, it mainly is connected to form by crank, connecting rod, walking beam, horse head, the wirerope that motor, retarder drive.Its deficiency is that machine volume is big, heavy, and it is many to consume steel, and the sucker rod reciprocating stroke is little, and pumping efficiency is low, manufacturing, operating cost height.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and can amplify stroke, the sucker rod stroke is long, and the pumping efficiency height, compact structure, volume are little, in light weight, save steel, saving power, the pumping unit that make, operating cost is low.This pumping unit can also be used to draw water; Or as other mechanical power source.
The technological scheme that solves its technical problem employing is: a kind of pumping unit, its characteristics are: it comprises frame 1, one reciprocating type lifting oil pumping mechanism, the structure of described reciprocating type lifting oil pumping mechanism is, both sides are provided with guide slide 7 in frame 1, the directed slide plate 8 that has upper saw pulley 17 matches with guide slide 7, on frame 1, be provided with pulley 13,14, the upper and lower end of directed slide plate 8 is connected with wirerope 4,18 respectively, the wirerope 4 contact pulleys 13,14 of upper end are connected with balancing weight 15, and the wirerope 18 of lower end is connected with sucker rod 16; One drive unit, the structure of described drive unit is, on frame 1, be provided with the driving shaft 2 that is connected with motorized speed reducer 3, described driving shaft is fixed with sprocket wheel 5 respectively on 2 two ends, described two sprocket wheels 5 are connected with two duplicate sprockets 6 on the driven shaft 19 on the frame that place that are positioned at described driving shaft top by chain respectively, described two duplicate sprockets 6 are connected with two sprocket wheels 12 on another driven shaft 20 that is positioned at the above driven shaft top of frame 1 by chain 11 respectively, on the described both sides chain 11 that connects two sprocket wheels on two duplicate sprockets and another driven shaft respectively, be fixed with cross-over connection axle 10, the pulley 9 that matches with the notch 21 of directed slide plate 8 is housed on cross-over connection axle 10.
The advantage applies of pumping unit of the present invention exists:
1. because pumping unit is big according to sucker rod rising needs power, descending needs the little characteristic of power, adopts the gravity of motorized speed reducer driving force and balancing weight to promote the sucker rod operation together; Adopt motorized speed reducer driving force and sucker rod deadweight decline together sucker rod operation, therefore, laborsaving, saving power;
2. the sucker rod of pumping unit is suspended on the directed slide plate, the pulley that matches with directed slide plate notch is loaded on the cross-over connection axle of chain, therefore, the running length of sucker rod is relevant with two sprocket shafts distance with sprocket diameter, can increase the running length that sprocket diameter strengthens sucker rod easily, improve the oil pumping rate;
3. this machine compact structure, volume are little, in light weight, save steel, make, operating cost is low.
4. can be according to this machine principle, or as other mechanical power source.
