Abstract
The utility model discloses a novel long column stopper sand control pump, including I type long column stopper sand control pump and II type long column stopper sand control pump, I type long column stopper sand control pump all is provided with upper segment pump barrel, hypomere pump barrel and long column stopper with II type long column stopper sand control pump, the hypomere pump barrel sets up in upper segment pump barrel bottom, set up in the upper segment pump barrel in the long column stopper, be provided with the fluid chamber in the long column stopper, the long column is held beyond the great wall and is stretched out upper segment pump barrel top, the utility model has the advantages of reasonable design, sand card problem can effectively be solved to I type long column stopper sand control pump under the not many condition of silt particle when oil pumping in -process or termination of pumping, and the sand sediment pipe that the sand control pump set up is filled in to II type long columns, can effectually solve the problem that sand buried the sucker rod, can prevent the oil pump wearing and tearing from to have improved the pump efficiency, has increaseed pump inspection period, and convenient to use has improved work efficiency.
Description
Technical field
This utility model relates to oil well pump technical field, a kind of novel long plunger sand control pump.
Background technology
Conventional oil well pump is substantially short-plunger, long pump barrel, in oil pumping process or during termination of pumping, the position that plunger is the deepest often in sinking to pump barrel, silt particle in oil pipe, slag thing etc. can sink in pump barrel, when plunger up stroke, these silt particles etc. easily clamp-on pump barrel with in the gap of plunger, accelerate oil pump abrasion, reduce pump efficiency, shorten pump detection period, time serious, cause holddown.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical disadvantages to provide a kind of novel long plunger sand control pump.
This utility model solves the technical scheme of technical problem employing: a kind of novel long plunger sand control pump, including I type long plunger sand control pump and II type long plunger sand control pump, described I type long plunger sand control pump and II type long plunger sand control pump are provided with epimere pump barrel, hypomere pump barrel and long-plunger, described hypomere pump barrel is arranged at epimere pump barrel bottom, it is arranged in described long-plunger in epimere pump barrel, in described long-plunger, is provided with fluid chamber；Epimere pump barrel top is stretched out in described long-plunger upper end.
Being provided with outer tube outside described II type long plunger sand control pump, described epimere pump barrel, hypomere pump barrel and long-plunger may be contained within outer tube, and described outer tube bottom is provided with sand sediment pipe.
Two delivery valves it are provided with in described long-plunger.
Described hypomere pump barrel bottom is provided with inlet valve, and described inlet valve end is connected with oil inlet pipe.
This utility model is had the beneficial effect that
This utility model reasonable in design, in oil pumping process or during termination of pumping, I type long plunger sand control pump is in the case of silt particle is not many, can effectively solve sand card problem, the sand sediment pipe that II type long plunger sand control pump is arranged, can effectively solve the problem that sand buries sucker rod, it is possible to prevent oil pump from wearing and tearing, improve pump efficiency, increase pump detection period, easy to use, improve work efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
1 pair of this utility model is described below below in conjunction with the accompanying drawings.
As shown in drawings, this utility model includes I type long plunger sand control pump 1 and II type long plunger sand control pump 2, and described I type is long
Plunger anti-sand pump 1 and II type long plunger sand control pump 2 are provided with epimere pump barrel 8, hypomere pump barrel 7 and long-plunger 5, and described hypomere pump barrel 7 is arranged at epimere pump barrel 8 bottom, is arranged in epimere pump barrel 8 in described long-plunger 5, is provided with fluid chamber 6 in described long-plunger 5；Epimere pump barrel 8 top is stretched out in described long-plunger 5 upper end；Described II type long plunger sand control pump 2 is outside is provided with outer tube 9, and described epimere pump barrel 8, hypomere pump barrel 7 and long-plunger 5 may be contained within outer tube 9, and described outer tube 9 bottom is provided with sand sediment pipe 7；Two delivery valves 3 it are provided with in described long-plunger 5；Described hypomere pump barrel 7 bottom is provided with inlet valve 4, and described inlet valve 4 end is connected with oil inlet pipe 12.
I type long plunger sand control pump 1 is with II type long plunger sand control pump 2 in the course of the work; epimere pump barrel 8 coordinates with long-plunger 5; the tolerance range of hypomere pump barrel 7 is relaxed; move on the position of tolerance range; fluid is in inlet valve 4 enters fluid chamber 6; discharge through delivery valve 3; I type long plunger sand control pump 1 is no matter when pumping or shutting down; long-plunger 5 length is more than epimere pump barrel 8; hypomere pump barrel 7 does not contacts with long-plunger 5; the slag things such as the silt particle of sedimentation cannot be introduced into pump barrel, in the case of silt particle is not many, can effectively solve sand card problem；II type long plunger sand control pump 2, with sand sediment pipe 11, facilitates sediment outflow, can effectively solve sand and bury the problem of sucker rod, improve work efficiency.
