Abstract
The utility model relates to a large interval channel eccentric wear proof oil-well pump, mainly solving the problem of the small area of passage and low efficiency existing in the present oil pump. The utility model is characterized in that a travelling valve seat (15) and a traveling valve ball (16) are arranged in a plunger valve cover (5), a lower screw thread is connected with a pipe stopper (6) on valve seat, three righting ribs (11) are arranged on an inner chamber wall of the upper end, forming three arc surfaces of flowing oil groove (12). A fixed valve seat (17) and a fixed valve ball (18) are arranged in a pump barrel valve cover (9), three righting ribs (13) are arranged on the inner chamber wall of the upper end, forming three arc surfaces of flowing oil groove (14). The large interval channel eccentric wear proof oil-well pump reduces the eccentric wear of the pumping rod and the wear of the oil pipe, increases pump efficiency, and reduces the maintenance cost.
Description
Technical field:
The utility model relates to used oil well pump in the oil recovery field, a kind of oil field, especially big runner eccentric wear prevention pumping pump.
Background technique:
In oil recovery field, oil field, oil well pump is one of visual plant.At present, the oil well pump majority that use in the oil field is common oil well pump, and the fixed valve base hole area of this oil well pump is less, and fixed valve ball and the standing valve cover area of passage when opening is also little.At latter period of oilfield development,, cause the increase of viscosity of crude with the popularization of polymer displacement of reservoir oil tech, make the descending resistance increase of plunger in the oil well pump, reduce the efficient of oil well pump, cause sucker rod partial wear, shorten the working life of sucker rod, pipe, shortened pump detection period.
The model utility content:
In order to overcome little, the inefficient deficiency of existing oil well pump area of passage, the utility model provides a kind of big runner eccentric wear prevention pumping pump, and this oil well pump has increased flow quantity, has reduced the wearing and tearing of the eccentric wear and the oil pipe of sucker rod, improve the efficient of pump, reduced maintenance cost.
Technical solutions of the utility model are: this oil well pump comprises pump barrel, the pump barrel lower end is the screwed connection box cupling successively, pump barrel valve bonnet and lower contact, the screwed connection upper connection of pump barrel upper end, be equipped with cylinder sleeve and plunger in the pump barrel successively, valve bonnet in the plunger upper end screwed connection, lower end screwed connection plunger valve bonnet, the valve seat of moving about and the valve ball that moves about are arranged in the plunger valve bonnet, lower end screwed connection valve seat pipe close, upper end inner chamber wall has three righting ribs, and forms the arc groove face of three stream oil grooves, and fixed valve base and fixed valve ball are arranged in the pump barrel valve bonnet, upper end inner chamber wall has three righting ribs, and forms the arc groove face of three stream oil grooves.
The beneficial effect that the utlity model has is: because this big runner eccentric wear prevention pumping pump, adopted and singly moved about valve ball and increased the area of passage of plunger valve bonnet, pump barrel valve bonnet, make the flow quantity of pump increase, liquid can in time be full of the space that plunger is abdicated when up, reduced the resistance of the stream of liquid when plunger is descending, liquid can be waltzed through in pump, reduced the wearing and tearing of the eccentric wear and the oil pipe of sucker rod plunger, prolong pump detection period, improved the efficient of pump.
Description of drawings:
Accompanying drawing 1 is the utility model structure half sectional view;
Accompanying drawing 2 is A-A sectional views of accompanying drawing 1;
Accompanying drawing 3 is B-B sectional views of accompanying drawing 1.
1-upper connection among the figure, the last valve bonnet lower contact of 2-, 3-plunger, the 4-cylinder sleeve, 5-plunger valve bonnet, 6-valve seat pipe close, the 7-pump barrel, 8-box cupling, 9-pump barrel valve bonnet, the 10-lower contact, 11-righting rib, 12-arc groove face, 13-righting rib, 14-arc groove face, the 15-valve seat that moves about, the 16-valve ball that moves about, 17-fixed valve base, 18-fixed valve ball.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By Fig. 1 in conjunction with Fig. 2, shown in Figure 3, this big runner eccentric wear prevention pumping pump comprises pump barrel 7, pump barrel 7 lower ends are screwed connection box cupling 8 successively, pump barrel valve bonnet 9 and lower contact 10, pump barrel 7 upper end screwed connection upper connections 1, be equipped with cylinder sleeve 4 and plunger 3 in the pump barrel 7 successively, valve bonnet 2 in the plunger 3 upper end screwed connections, lower end screwed connection plunger valve bonnet 5, the valve seat of moving about 15 is arranged and the valve ball 16 that moves about in the plunger valve bonnet 5, lower end screwed connection valve seat pipe close 6, upper end inner chamber wall has three righting ribs 11, and form the arc groove face 12 of three stream oil grooves, fixed valve base 17 and fixed valve ball 18 are arranged in the pump barrel valve bonnet 9, and upper end inner chamber wall has three righting ribs 13, and forms the arc groove face 14 of three stream oil grooves.
In actual use, upper connection 1 and lower contact 2 respectively with the oil pipe screwed connection, last valve bonnet 2 and sucker rod screwed connection, the power of oil well pump is delivered to underground through sucker rod from ground, make the plunger 3 of oil well pump reciprocating in cylinder sleeve 4, liquid in the oil well is given rise to ground along oil pipe, finish oil extraction operation.When plunger 3 was up, the following pump chamber volumes below the plunger 3 became big, and fixed valve ball 18 leaves fixed valve base 17, and liquid is full of pump chamber down just at an easy rate by bigger arc groove face 14; Meanwhile, the valve ball 16 that moves about drops on the valve seat 15 that moves about, and will go up pump chamber and seal fully; Liquid in the last pump chamber above the plunger 3 is discharged on the ground along oil pipe.When plunger 3 is descending, plunger 3 compression fixed valve balls 18 and the liquid between the valve ball 16 of moving about, fixed valve ball 18 drops on the fixed valve base 17, and liquid is sealed, and it can not be flowed downward.The valve ball 16 that meanwhile moves about leaves the valve seat 15 that moves about, and the liquid in the pump chamber is successfully entered in the pump chamber through bigger arc groove face 12.Plunger 3 so moves reciprocatingly, and finishes the process of oil pumping.This oil well pump flow quantity has reduced the wearing and tearing of the eccentric wear and the oil pipe of sucker rod, has improved the efficient of pump, has reduced maintenance cost.
