Abstract
An oil well operation piston pump consists of a reducer, a cylinder body, a piston which slides in the cylinder body, a crankshaft connecting rod mechanism which connects the reducer and the piston, a pump head body buckled on top end of the cylinder body which is provided with a suction-in valve and a discharging valve; the utility model is characterized in that an axis line in which the crankshaft center is arranged offsets a plane in which the piston is arranged. The utility model has the main advantages of light weight, small volume, large discharge quantity and high pressure, and is especially suitable for oil field operation.
Description
Technical field
The utility model relates to a kind of oil well operation plunger pump, especially by retarder, cylinder body, slide on the crankshaft ﹠ connecting of plunger, connection reducer and plunger in the cylinder body and be fastened on the cylinder body top and have the oil field operation plunger pump that the pump head body of suction valve and drain is formed.
Background technique
In the prior art, general plunger pump all be by bent axle by connecting rod, rotatablely moving of bent axle is converted into plunger to-and-fro motion in the cylinder body, suck liquid through suction valve, through the delivery valve drain.But in this design, the bent axle axle center realizes that the physical space of above-mentioned working procedure needs is bigger on the horizontal plane of plunger place, make the pump housing bulky, and weight is high.
Test novel content
The purpose of this utility model is to improve oil well operation plunger pump structure, reduces pump housing volume and weight, or at volume under similar circumstances, increases stroke as far as possible, improves discharge capacity.
In order to achieve the above object, the utility model is provided with design proposal: oil well operation plunger pump, by retarder, cylinder body, slide on the crankshaft ﹠ connecting of plunger, connection reducer and plunger in the cylinder body and be fastened on the pump head body that the cylinder body top has suction valve and an expulsion valve and form, it is characterized in that: the plane at crankshaft center place journal offset plunger place.
And retarder places the left side or the right side of pump, can be installed on any one input shaft position of crankshaft ﹠ connecting.
And, be provided with many group cylinder bodies and supporting plunger, suction valve, expulsion valve in the pump, and the suction main that all suction valves are coupled together.
And, can select for use two kinds of specification pump head bodies to dispose the plunger of 6 kinds of sizes.
After the utility model adopted such design, the shared space of crank-connecting rod reduced, and has effectively reduced the overall volume of oil well operation plunger pump, has alleviated its weight, and the oil well for needs operation in the open air is significant.
Description of drawings
Fig. 1 is the whole plan view that constitutes of the utility model;
Fig. 2 is the longitudinal sectional drawing of the utility model preferred forms.
Embodiment
Referring to Fig. 1,2,3, the utility model preferred forms is described in detail below with reference to accompanying drawing.
Oil well operation plunger pump is by retarder 1, cylinder body 2, slide on the plunger 3 in the cylinder body 2, the crankshaft ﹠ connecting 4 of connection reducer 1 and plunger 3, and be fastened on the pump head body 5 that cylinder body 2 tops have suction valve 6 and expulsion valve 7, in order to reach the purpose of improving structure, the utility model is specifically designed to offset, it is the plane at bent axle 8 center place journal offset plunger 3 places, shown in e among the figure, the power and the fluid power effect of oil well operation plunger pump no longer are positioned on the axis, then crankshaft ﹠ connecting 4 takies littler volume, can offer simultaneously the longer stroke of plunger 3, increase oil well operation plunger pump delivery, improve pressure.
In order to improve the adaptability of the utility model in the layout of equipment, retarder 1 can be positioned on the left side or the right positions of pump, selection is installed on any one input shaft position in the crankshaft ﹠ connecting 4, makes retarder 1 can adapt to the different driving route of oil well operation plunger pump.Can select the position concrete condition of installing by adopt between crankshaft ﹠ connecting 4 and the retarder 1 the connection decision, in the present embodiment, selectable number is 16.
Further technological scheme can be: many group cylinder bodies 2 and supporting plunger 3, suction valve 6, expulsion valve 7 are set, and the suction main 9 that all suction valves 6 are coupled together.The power of plunger 3 is provided by crankshaft ﹠ connecting 4 simultaneously in all cylinder bodies 2, and the fluid power that plunger 3 to-and-fro motion produce is then simultaneously by pump head body 5 effects.Described many groups mean two groups or more, generally are no more than five groups.
The utility model can be used two kinds of specification pump head bodies 5 instead to dispose the plunger 3 of 6 kinds of sizes (2 1/2 ", 2 3/4 ", 3 ", 3 1/2 ", 4 ", 4 1/2 "), can satisfy the requirement of oil field to different pressures and discharge capacity.The structure of the pump head body of described two kinds of specifications does not have substantial difference, so be unworthy of accompanying drawing.
Most preferred embodiment of the present utility model adopts three cylinder offsets, carries out between oil well operation plunger pump product at home comparing under the equal-wattage, and this pump weight is the lightest, and 2100Kg is only arranged, the volume minimum, and the discharge capacity maximum (can reach 2.1m
3/ min), pressure the highest (can reach 143Mpa) is the ideal equipment of open-air oil field operation.
Claims (4)
1. oil well operation plunger pump, by retarder, cylinder body, slide on the crankshaft ﹠ connecting of plunger, connection reducer and plunger in the cylinder body and be fastened on the pump head body that the cylinder body top has suction valve and an expulsion valve and form, it is characterized in that: the plane at crankshaft center place journal offset plunger place.
2. oil well operation plunger pump according to claim 1 is characterized in that: retarder places the left side or the right side of pump, and the mounting point is on any one input shaft of crankshaft ﹠ connecting.
