Abstract

The utility model relates to a vertical beam-pumping unit which belongs to a beam-pumping unit. A beam-pumping unit takes the main task of oil production when an oil well is working with suction pressure. Because the load of the beam-pumping unit in the prior art can only satisfy the need in a 48-80m<3>/d oil well whose load is 6 to 14 tons, the existing beam-pumping unit can not be used for big discharge, high load oil wells. So the utility model adopts a vertical beam-pumping unit which comprises a motor, a shaft coupling, a reducer, a roller, flexible material, balance weight rod, a front crowned pulley and a back crowned pulley, which uses intelligent control to realize stepless adjustment of the stroke and the frequency of stroke and the oil pumping in a high load oil well. Because the simple structure, the light weight and the stroke of more than 8 meters, and because of the adoption of separate electrohydraulic brakes among which the manual brake make the operation of the system safe and reliable, the device can be widely used in high load oil wells.

Description

A kind of vertical oil-pumping machine
Technical field:
The utility model relates to a kind of vertical oil-pumping machine, belongs to oil-field oil pumper device class.
Background technique:
After pumping unit was gone into operation, by reasons such as well down-hole crude oil property and strata pressure are lower, some oil wells will adopt pumping unit to recover the oil, and the pumping unit of using can only satisfy oil well discharge capacity 48-80m at present 3The oil well of/d, load 6-14 ton needs, for big production fluid amount, and the long stroke of the well recovery demand of loading greatly, heavy upright intelligent pumping unit is not reported.
The model utility content:
The utility model purpose be in order to overcome above-mentioned shortcoming, and a kind of vertical oil-pumping machine that provides can satisfy the big production fluid amount in oil field, and big load recovers the oil and needs.
The technological scheme of model utility:
For achieving the above object, the utility model is made up of by retarder, drive roll and oil-extractor polish-rod that coupling connects the motor of base top; Described drive roll top is wound with the flexible thing of adhesive tape, this flexibility thing one end is connected with oil-extractor polish-rod with the back crown sheave by preceding crown sheave, the other end and ballast box link, and forward and backward crown sheave links with the device of stepping down, and described motor, retarder are connected with manual brake with hydraulic brake.
Described motor is positive and negative drive manner, uses Single-chip Controlling.
Described support is a truss structure, master rotor is cylindric, wherein drum surface 1/ 4Length is the ashamed shape that bursts at the seams, 3/ 4Length is the arc spiral wire.
Described flexible thing material is that rubber or steel cable, nylon rope are made.
The utility model compared with prior art has distinguishing feature.
Because the utility model has adopted the intellectualized operation system, can realize the pumping unit stroke, the jig frequency step-less adjustment can be fit to the oil well needs of long stroke, rotating power partly is placed on ground location in addition, can satisfy job requirements, during construction, and do not need any lifting appliance, transmission device has used flexible thing rope hanger, can load according to the down-hole, convenient especially during replacing, this device utilizes ballast box to replace former pumping unit pouring weight, on the oil-extractor polish-rod, under move through before, back crown sheave means of fixation, thus horse head equipment removed with direct drive of motor, therefore, alleviated pumping unit weight, just used, reverse motors also can increase the pumping unit operation power, thereby can satisfy big load needs.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model side view.
Among the figure by 1, drive roll, 2, coupling 3, motor, 4, hydraulic brake, 5, retarder, 6, manual brake, 7, base, 8, support, 9, flexible thing, 10, ballast box, 11, the device of stepping down, 12, platform, 13, the back crown sheave, 14, guide wheel, 15, preceding crown sheave, 16, polished rod forms.
Embodiment:
The utility model is provided by following examples.
Below in conjunction with accompanying drawing the utility model is described further.
Among Fig. 1,2, drive roll 1 is installed in ground, is positioned at the pumping unit side, and this cylinder is a metallic cylinder, is wound with flexible thing (rope hanger) above the cylinder, its cylinder surface 1/ 4Length is involute, 3/ 4Length is the arc spiral wire, can be beneficial to like this and curl rope hanger, there are coupking shaft 2 and motor 3 to be connected in the middle of the drive roll 1 by key, motor 3 adopts variable-frequency motor, can just change and reverse, hydraulic brake 4 is installed on the table top of motor 3 with retarder 5 manual brakes 6, and base 7 tops are welded on the top with welding manner with support 8, and support 8 is a truss structure, employing special tooling location, ballast box 10 is a metal pouring weight, and its effect has been balanced action, during work, with rope hanger is on the flexible thing 9, following motion, the device 11 of stepping down can make the wheel lift day before yesterday, abdicates working space, demand in the time of can satisfying operation.
Described forward and backward crown sheave 13,15 is an alloy steel forging, described motor 3 has adopted intelligent control system (figure does not draw), the acceleration of may command motor, deceleration, clockwise and anticlockwise also can utilize single-chip microcomputer and intelligent control system to carry out communication, show Operational Limits, carry out Variation.
Embodiment 2:
The utility model working method:
Motor 3 outputting powers are through elastic sleeve coupling 2, pass to retarder 5 input shafts, output shaft output through retarder, drive drive roll 1 rotation by cardan shaft coupling 2, rely on the clockwise and anticlockwise of intelligent control system control motor 3, drive drive roll 1 clockwise and anticlockwise, do the repetition straight line motion by polished rod 16 in the flexible thing 9 drive well heads that are wrapped in the top and ballast box 10 and reach the oil pumping purpose.
The utility model can satisfy individual well day production fluid 350-400m 3/ d pumping well needs, 8 meters of the upper and lower strokes of this pumping unit, the highest jig frequency 4 times/minute, 20 tons of pumping unit polished rod loads.
