Abstract
The utility model relates to an oil pumping pump preventing a fixed valve from leaking. The oil pumping pump comprises an oil pumping rod, a piston, a pump cylinder and a fixed valve device. The fixed valve device mainly comprises a valve cover and a valve ball, and the oil pumping rod and a piston connection body are arranged in the pump cylinder. The oil pumping pump preventing the fixed valve from leaking is characterized in that a section of a dislocation guiding pipe is connected between the pump cylinder and the fixed valve device through screw threads, the dislocation guiding pipe is divided into an A cavity body and a B cavity body both of which are communicated with a section of a throat pipe. The throat pipe is communicated with the bottom of the A cavity body and the top of the B cavity body. The oil pumping pump can prevent dirty pieces and other sundries from falling into the fixed valve to block the fixed valve when the dirty pieces and other sundries flow down along an oil pipe, therefore, the fixed valve does not leak oil, the efficiency of the pump is improved, cost is saved, in addition, the oil pumping pump is simple in structure and easy to popularize and apply.
Description
Technical field
The utility model relates to a kind of pumping tool, is specifically related to the oil well pump that a kind of anti-standing valve leaks.
Background technique
Affected by rise in price and the continuous compression of operating cost of the devices such as oil well oil conduit, sucker rod, in order further to increase economic efficiency, the completion tubular bar of at present oil field use mainly is to repair oil pipe and repair sucker rod.We at present used reparation pipe bar in whole repair process, the layer of scale of sucker rod surface and tube inner wall and impurity always can not clean up fully, after R a T passes through open-air oxidation, drying, the impurity layers such as fouling and tube inner wall, sucker rod surface lifting, when carrying out the construction such as lower oil pipe, lower sucker rod, the impurity such as fouling is easy to come off and drops in oil pumping barrel in the work progress, enters standing valve, thereby cause pump efficiency to reduce, even standing valve leak not fuel-displaced.And to clear up not only unusual trouble of the impurity such as these foulings, and and can't thoroughly clean out, be to need urgent problem on the oil field so how effectively to avoid the impurity such as fouling to enter standing valve.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of above prior art, and the oil well pump that a kind of anti-standing valve leaks has been proposed, this oil well pump can avoid dirty sheet and other foreign material in lower Tubing During Running, drops in the pump standing valve, cause standing valve to stop up, cause standing valve to leak not fuel-displaced, improved pump efficiency, saved cost, and this oil well pump is simple in structure, is easy to apply.
The utility model scheme is achieved by the following technical measures:
The oil well pump that a kind of anti-standing valve leaks, comprise sucker rod, piston, pump barrel, standing valve device, the standing valve device mainly comprises valve cover and valve ball, be provided with sucker rod and piston connecting body in the pump barrel, its characteristics are in the middle of pump barrel and standing valve device by one section dislocation of screwed connection honeycomb duct, the dislocation honeycomb duct is divided into A, two cavitys of B, is connected by one section trunnion between two cavitys.
Above-described trunnion is communicated with the bottom of A cavity and the top of B cavity.
Above-described A, two cavitys of B are set up in parallel, and the width of B cavity is greater than the diameter of trunnion.
The width of above-described B cavity is 0.5-2 times of throat pipe diameter.
The beneficial effects of the utility model are: added oil well pump dislocation honeycomb duct in the middle of pump barrel and standing valve, make in lower oil well pump, Tubing During Running, the foreign material that the factors such as the dirty sheet that drops from tubing wall and manual operation carelessness drop fall into the inside, A chamber of dislocation honeycomb duct, have prevented that effectively foreign material from falling in the standing valve; Simultaneously, during oil well pump work, in the descent of piston process, the relative pump barrel of crude oil in the pump barrel is static, therefore the sand in the crude oil easily deposits, can drop into the A chamber like this, can not be deposited in the standing valve, in the piston stroking upward process, crude oil enters the B chamber through standing valve, trunnion by dislocation refluence pipe enters the A chamber, because trunnion is thinner than B chamber, the crude oil pressure energy is converted into kinetic energy in the trunnion ingress, in trunnion, form jet, directive A chamber, thus the foreign material that are deposited to bottom, A chamber are washed away, enter oil pipe by piston and then discharge pit shaft.Cause standing valve to stop up with regard to fundamentally having avoided the impurity such as fouling to enter standing valve like this, cause standing valve to leak not fuel-displaced problem, improved pump efficiency, reduced use and maintenance cost, have higher economic benefit and social benefit.
Description of drawings
Fig. 1 is the structural representation of the oil well pump of a kind of anti-standing valve leakage described in the utility model, and wherein 1 is pump barrel, and 2 are the dislocation honeycomb duct, and 3 is the standing valve device, and 4 is screw thread, and 5 is sucker rod, and 6 is piston, and 7 is valve cover, and 8 is valve ball, and 9 is trunnion.
Embodiment
In order to make the technical solution of the utility model clearer, the utility model is further described with embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the oil well pump that a kind of anti-standing valve leaks, comprise sucker rod 5, piston 6, pump barrel 1, standing valve device 3, standing valve device 3 mainly comprises valve cover 7 and valve ball 8, be provided with the connecting body of sucker rod 5 and piston 6 in the pump barrel 1, its characteristics are to connect one section dislocation honeycomb duct 2 by screw thread 4 in the middle of pump barrel 1 is connected with the standing valve device, and dislocation honeycomb duct 2 is divided into A, two cavitys of B, is connected by one section trunnion 9 between two cavitys.
Above-described trunnion 9 is communicated with the bottom of A cavity and the top of B cavity.
Above-described A, two cavitys of B are set up in parallel, and the width of B cavity is greater than the diameter of trunnion 9.
The width of above-described B cavity is 0.5-2 times of trunnion 9 diameters.
At lower oil well pump, in the Tubing During Running, the foreign material that the factors such as the dirty sheet that drops from tubing wall and manual operation carelessness drop fall into the inside, A chamber of dislocation honeycomb duct 2, simultaneously, during oil well pump work, in piston 6 descending processes, sand in the pump barrel 1 interior crude oil easily deposits, and falls into the A chamber, in piston 6 up processes, crude oil enters the B chamber through standing valve device 3, trunnion 9 by dislocation honeycomb duct 2 enters the A chamber, because trunnion 9 is thinner than B chamber, is converted into kinetic energy at trunnion 9 ingress crude oil pressure energies, at trunnion 9 interior formation jets, directive A chamber, thus the foreign material that are deposited to bottom, A chamber are washed away, enter oil pipe by piston 6 and then discharge pit shaft.
