Abstract
A macroscopic path solid plunger rod-typed oil-well pump comprises a retaining adaptor, a pump cylinder, a solid plunger, an oil pipe,a connecting pipe, an adaptor, a delivery valve, an oil inlet valve, a sealing fixing device and a sealing fixing holder, wherein the oil pipe, the connecting pipe and the sealing fixing holder are respectively connected from up to down, and the pump cylinder, the adaptor, the delivery valve, the oil inlet valve and the sealing fixing device are respectively connected from up to down. The sealing fixing device is arranged in the sealing fixing holder, and the solid plunger is arranged in the pump cylinder which is arranged in the oil pipe, also the solid plunger is cooperated with the pump cylinder to achieve the function of sealing. The retaining adaptor with the inner diameter of the retaining adaptor being smaller than the diameter of the solid plunger is connected on the upper pump cylinder, and the length of the pump cylinder is shorter than the solid plunger. The plunger without arranging the delivery valve of the solid plunger rod-typed oil-well pump is solid, and the base oil does not flow from the plunger, with the flow passage being changed, and the diameter of the valve ball having no limitation of the pump diameter, thereby enlarging the diameter of the valve ball, and increasing the mass of the valve ball. With the valve ball working flexibly, the rod-typed oil-well pump works reliably.
Description
One, technical field
The utility model is the downhole pump that a kind of oil field machinery oil is used, particularly a kind of major path solid post stopper rod formula oil well pump.
Two, background technique
The pump barrel of rod-type pumping unit and oiling valve can be lowered to or be proposed by sucker rod, therefore, the well of following rod-type pumping unit is when operation inspection pump, only need to propose the purpose that whole sucker rods just can be realized the inspection pump, do not need to propose oil pipe, the work operations amount is few, and the darker oil well of following pump more can embody its superiority, but the darker oil well of following pump generally all is the very low oil well of oil output, under oil well pump also less, in existing rod-type pumping unit, all be that outlet valve is installed on plunger, fluid passes through from plunger, when the oil well pump diameter hour, be subjected to size restrictions, valve ball, runner is less, valve ball can be malfunctioning, causes air pump inoperative.
Three, summary of the invention
The purpose of this utility model is a kind of major path solid post stopper rod formula oil well pump of design, makes its valve ball diameter not be subjected to the oil well pump diameter restrictions by changing runner, can increase the valve ball diameter, improves the reliability of rod-type pumping unit.
The purpose of this utility model is achieved in that by pump barrel, solid plunger, oil pipe, connecting tube, joint, outlet valve, oiling valve, sealed fixing device, the sealing and fixing seat is formed, oil pipe, connecting tube, the sealing and fixing seat connects from top to bottom successively, pump barrel, joint, outlet valve, oiling valve, sealed fixing device connects from top to bottom successively, sealed fixing device is installed in the sealing and fixing seat, solid plunger is in pump barrel, pump barrel is in the oil pipe, solid plunger cooperates with pump barrel and seals, the retaining joint is connected in pump barrel top, retaining joint internal diameter is less than the diameter of solid plunger, and the length of pump barrel is greater than the length of solid plunger.
The beneficial effects of the utility model are: the plunger of solid post stopper rod formula oil well pump is solid, crude oil does not flow in plunger, changed runner, uneasiness takes on fuel tap on the plunger, make its valve ball diameter not be subjected to the pump diameter restrictions, can increase the valve ball diameter, the valve ball quality increases, thereby valve ball work is flexible, the rod-type pumping unit reliable operation.
Four, description of drawings
Accompanying drawing is a solid post stopper rod formula oil well pump embodiment erection drawing.
Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in the figure, by retaining joint (1), pump barrel (2), solid plunger (3), oil pipe (4), connecting tube (5), joint (6), outlet valve (7), oiling valve (8), sealed fixing device (9), sealing and fixing seat (10) is formed, oil pipe (3), connecting tube (5), sealing and fixing seat (10) connects from top to bottom successively, pump barrel (2), joint (6), outlet valve (7), oiling valve (8), sealed fixing device (9) connects from top to bottom successively, sealed fixing device (9) is installed in the sealing and fixing seat (10), solid plunger (3) is in pump barrel (2), pump barrel (2) is in the oil pipe (4), solid plunger (3) cooperates with pump barrel (2) and seals, it is characterized in that: retaining joint (1) is connected in pump barrel (2) top, retaining joint (1) internal diameter is less than the diameter of solid plunger (3), and the length of pump barrel (2) is greater than the length of solid plunger (3).Oil pipe 4 tops connect oil pipe on the pump, and solid plunger 3 tops connect sucker rod.
Oil pipe 4, connecting tube 5, sealing and fixing seat 10 are earlier with oil pipe G.I.H on the pump, retaining joint 1, pump barrel 2, joint 6, outlet valve 7, oiling valve 8, sealed fixing device 9 are lowered in the oil pipe 4 with sucker rod again, under the rod weight effect, sealed fixing device 9 is pressed in the sealing and fixing seat 10, and oil well pump just can be worked.Sucker rod drives solid plunger 3 when up, and the cavity volume of solid plunger 3 bottoms increases, and the pressure in it descends, and oiling valve 8 is opened, and crude oil is in the lateral access 7-1 of oiling valve 8 and outlet valve 7 enters the cavity of solid plunger 3 bottoms in the well.Sucker rod drives solid plunger 3 when descending, the cavity volume of solid plunger 3 bottoms reduces, pressure in it rises, oiling valve 8 cuts out, crude oil in the cavity is upwards opened the annular space that outlet valve 7 is expelled to outlet valve 7 and connecting tube 5 from the central passage 7-2 of outlet valve 7 downwards again through the lateral access 7-1 of outlet valve 7, is discharged to ground then.
