Abstract
A novel anti-breaking oil well pump relates to a device used in oil well production and overcomes shortages of other techniques. The novel anti-breaking oil well pump is structurally characterized in that a stop ball pin is mounted on an upper strengthened oil outlet valve bonnet, a valve ball mounted at the lower end inside the upper strengthened oil outlet valve bonnet is in threaded connection with a plunger, the lower end of the plunger is in threaded connection with a lower oil outlet valve bonnet assembly, another stop ball pin is mounted in a lower oil outlet valve bonnet to limit a lower valve ball in an inner bore of the lower oil outlet valve bonnet, an upper connecting collar is in threaded connection with an outer tube, the lower end of the outer tube is in threaded connection with an intermediate connecting collar, a centralizer joint is in threaded connection with a pump cylinder, the lower end of the pump cylinder is in threaded connection with the intermediate connecting collar, the lower end of the intermediate connecting collar is in threaded connection with a nipple, the lower end of the nipple is in threaded connection with a fixed valve assembly, and a fall protection shield is in threaded connection with the fixed valve assembly.
Description
One, technical field: the utility model relates to a kind of device that uses in the oil well production, especially a kind of novel anti-breaking oil well pump that takes off.
Two, background technique: at present the oil well liquid-supplying deficiency often adopts little pump to take out technology deeply, but little pump is taken out deeply and existed many shortcomings and mainly show following several aspect: go up that valve bonnet disconnectedly takes off, the pump barrel stress deformation.1, because the oil well pump size is less, and last valve bonnet is subjected to spatial constraints, and wall thickness is less, body intensity is low; 2, rod string is longer, and the pull bar diameter is little, and in oil pumping process, it is bigger to bear alternate load, and is attended by impulsive load, has quickened main body destruction; 3, upward the fuel-displaced slotted hole groove of valve bonnet is exactly the ball chamber, and valve ball constantly impacts valve bonnet in oil pumping process, has quickened the wearing and tearing of valve bonnet inwall; 4, pump barrel stress deformation: because pump setting depth is darker, liquid column hydrostatic pressure is big in the oil pipe, and the pump barrel pressure is also bigger, has quickened the distortion of pump barrel, and after the pump barrel distortion, the suffered pulling force of plunger also increases, and has quickened the disconnected of last valve bonnet and has taken off.
Three, summary of the invention: the purpose of this utility model provides a kind of novel anti-breaking oil well pump that takes off that can increase the service life, it has overcome the shortcoming that other technology exists, the purpose of this utility model is to realize like this, it is by strengthening going up oil-release valve cover, shelves ball pin, last box cupling, set upright joint, plunger, pump barrel, outer tube, shelves ball pin, following oil-release valve cover assembly, middle box cupling, anti-junk cover, pipe nipple and standing valve assembly are formed by connecting, on plunger piston assembly, a grade ball pin is installed on the oil-release valve cover in the reinforcement, valve ball is installed on reinforcement and upward is connected with plunger screw the interior lower end of oil-release valve cover, shelves ball pin can be limited in valve ball to be strengthened going up in the endoporus of oil-release valve cover, valve ball just can not arrive and strengthen going up in the fuel-displaced slotted hole of oil-release valve cover like this, thereby the wall thickness in the slotted hole can be thickeied, and has increased solid strength.The plunger lower end is threaded with following oil-release valve cover assembly, and a grade ball pin also is installed in the following oil-release valve cover, and lower valve ball is limited in down in the oil-release valve cover endoporus.
On the pump barrel assembly: go up box cupling and be connected with external pipe thread, the outer tube lower end is threaded with middle box cupling, setting upright joint is threaded with pump barrel, the pump barrel lower end is threaded with middle box cupling, middle box cupling lower end is threaded with pipe nipple, the pipe nipple lower end is threaded with the standing valve assembly, and anti-junk cover is threaded with the standing valve assembly.
Working principle: plunger piston assembly links to each other with sucker rod, and the pump barrel assembly links to each other with oil pipe and is installed in the well, and plunger piston assembly pumps in pump barrel under the drive of sucker rod.Finish the lifting of liquid in the well.
Meaning of the present utility model: the one, valve bonnet structure in the reinforcement: the valve seat mounting hole is moved down, on the ball chamber, insert the pin of shelves ball, after the valve seat mounting hole moves down, valve ball will not enter in the slotted hole, the slotted hole wall thickness will no longer be subjected to the constraint of valve ball like this, thereby can thicken, and improve the intensity of slotted hole so greatly, valve ball also no longer impacts slotted hole simultaneously, thereby has reduced wearing and tearing.The 2nd, increase outer protection of pipe pump barrel; Increase outer protection of pipe pump barrel, pump barrel is not subjected to the pulling force of tubing string under the protection of outer tube, has improved the force environment that is subjected to of pump barrel, has reduced the distortion of pump barrel, has prolonged working life.
Four, description of drawings: Fig. 1 is a kind of novel anti-breaking structural representation that takes off oil well pump, oil-release valve cover 2, shelves ball pin 3 among the figure 1, in the reinforcement, go up box cupling 4, set upright joint 5, plunger 6, pump barrel 7, outer tube 8, shelves ball pin 9, oil-release valve cover assembly 10, middle box cupling 11, anti-junk cover 12, pipe nipple 13, standing valve assembly down
Five, embodiment: in Fig. 1, on plunger piston assembly, a grade ball pin 2 is installed on the oil-release valve cover 1 in the reinforcement, valve ball is installed on reinforcement and upward is threaded with plunger 5 oil-release valve cover 1 interior lower end, shelves ball pin 2 can be limited in valve ball to be strengthened going up in the endoporus of oil-release valve cover 1, valve ball just can not arrive and strengthen go up in the oil-release valve cover 1 fuel-displaced slotted hole like this, thus the wall thickness in the slotted hole can thicken, increased solid strength.Plunger 5 lower ends are threaded with following oil-release valve cover assembly 9, and a grade ball pin 8 also is installed in the following oil-release valve cover, and lower valve ball is limited in down in the oil-release valve cover endoporus.
On the pump barrel assembly, box cupling 3 is threaded with outer tube 7, outer tube 7 lower ends are threaded with middle box cupling 10, setting upright joint 4 is threaded with pump barrel 6, pump barrel 6 lower ends are threaded with middle box cupling 10, middle box cupling 10 lower ends are threaded with pipe nipple 12, and pipe nipple 12 lower ends are threaded with standing valve assembly 13, and anti-junk cover 11 is threaded with standing valve assembly 13.
