Abstract

A vertical-type single-cylinder single-acting beam compressor has the shape of the overall compressor being of cylindrical structure similar to that of a simple bicycle pump. The compressor comprises parts such as a connecting rod, a piston, a main frame and a head holder, wherein the main frame is fixed; both ends of the connecting rod are of full-floating connection structure; no packing locating mechanism is arranged and the connecting rod body is uneasy to be worn; a composite raceway is arranged inside the head holder of the main frame to make the dustproof block nested on the connecting rod have dustproof function in dynamic state; the dustproof block is made from low-friction material and no lubrication is needed; the head holder of the main frame is sealed and no lubricating grease needs to be added during working. The beam compressor which is arranged on the front arm of an oil pumping unit beam is driven by the beam to work so as to pump out the petroleum and natural gas inside an oil pump well casing, thereby reducing air pressure of the casing to keep optimal state of single well oil output so as to reach the goal of increasing production. Therefore, the beam compressor is an ideal equipment for disseminating and applying technology of crude oil decompression and yield increase in oil pumping well.

Description

Beam compressor

Beam compressor is a kind of in order to extract the petroleum gas in the oil oil-pumping well sheath out, and reduction sleeve pipe atmospheric pressure is to carry out the special device of applying " step-down incremental oil production technology " on oil field pumping well.This machine is installed on the walking beam forearm of pumping unit, drives compressor work by " leaving unused " power of walking beam down stroke, is a kind of simple and easy Beam compressor (hereinafter to be referred as compressor) of vertical, single-cylinder single-acting.

The present known technology in this technical field has three pieces of special review literary compositions such as WORLDQiL/JULY.1992 P71-76, the SPE11573 of the U.S. and SOUTHWESTERNPETROLEUN SHORT COURSE.88.These three pieces of papers all disclose the structure and the scheme of installation of this compressor.When the compressor operating of disclosed these three kinds of structural similarities, all be complete machine along with piston rod is swung together, when piston rod was put oblique position, a part of body quality was pressed on the piston rod, cause piston rod with the location packing be easy to wearing and tearing; Because it is piston rod is provided with the packing positioning means, lubricated by artificial intermittent oiling; Swing during again owing to body work, the inlet and outlet pipeline that is installed on it is easy to generate fatigue fracture also along with swing, thereby causes complete machine of short duration working life, and this is the shortcoming that causes of these several looms, is limiting applying of this compressor.

In view of the problem that exists in the above-mentioned known technology, the purpose of this utility model is: thus a kind of not easy to wear, artificial long-lived Beam compressor of the lubricated energy of refuel(l)ing of connecting rod that makes of design.

The technological scheme of the utility model Beam compressor is shown in Figure of description.

Among the figure: 1. compound raceways 5. dustproof 7. plug oil pumps of the piece 6. body headstocks, 8. pistons, 9. bodies, 10. suction valves, 11. outlet valves, 12. pumping unit beam travelling supportings of pumping unit horsehead 2. pumping unit walking beams 3. connecting rods 4.

As can be known, the technical solution of the utility model is design like this: the compressor machine shape is a cylindrical structural, similar easy bicycle pump from accompanying drawing.This machine is made up of several big component such as connecting rod 3, piston 8, body 9 and the body headstocks 6.Body is fixed.Connecting rod two ends are full floating connecting structures, and the non-stuffing positioning means has only dustproof piece suit on it.Be provided with the dustproof piece 5 of compound raceway 4 and band arc wing plate in the body headstock.Compressor is installed between pumping unit horsehead 1 and the pumping unit beam travelling supporting 12, combines as a whole by connecting rod 3 and pumping unit walking beam 2.Axle plug oil pump 7 is done standby, and suction valve 10 is air-breathing usefulness, and outlet valve 11 is that exhaust is used.

The technical solution of the utility model is achieved in that body 9 is fixed, and during compressor operating, a connecting rod 3 is done in body 9 up and down reciprocatingly and swung, and drives piston 8 work.Because non-stuffing positioning means on the connecting rod 3, the dustproof piece 5 of cuff on it plays dustproof effect, so connecting rod 3 external diameters are not easy to wear; Connecting rod two ends all are equipped with plain radial bearing, form the coupling mechanism of a full floating, and mechanical disturbance is not taken place in power transmission, only piston are produced slight radial force during swing, have improved the working condition of compressor widely.Be provided with compound raceway 4 in the body headstock, make the dustproof effect of dustproof piece under when connecting rod swing, playing dynamically.Dustproof piece 5 is circular body structures of two blocks of band wing plates of splitting, closes and disturbs cuff on connecting rod, prevents that dust from entering in the body, and it is to make with the PTFE material of low friction resistance, need not lubricate; The compound raceway 4 of dustproof piece in the body headstock 6 seals, midway lubricating oil filling fat; The lubricated of piston ring is to realize with the lubricant oil that is contained in piston 8 tops, and just it is enough only once to add enough amounts during installation.

Because adopted in this machine technology scheme that body 9 maintains static, non-stuffing positioning means and two ends are designed to the full floating connecting structure on the connecting rod 3, and complete machine multinomial technical measures such as hand oiling is lubricated midway, the working condition of complete machine is greatly improved, promoted the prolongation in complete machine working life, thus the purpose of the model utility of " thereby design a kind of make connecting rod is not easy to wear, not needing that artificial refuel(l)ing is lubricated can long-lived Beam compressor " of having realized the utility model proposes.

The realization of Beam compressor provides a kind of desirable equipment for apply " step-down incremental oil production technology " on oil field pumping well.
