Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of oil well pump, as depicted in figs. 1 and 2, comprise the tubing coupling 1 of coaxial connection successively, outer pump barrel 7, oiling valve valve seat 12 and lower connector 13, outer pump barrel 7 and oiling valve valve seat 12 are threaded connection, and oiling valve valve seat 12 are provided with oiling valve valve ball 9, oiling valve valve seat 12 are coaxially connected with interior pump barrel 8, interior pump barrel 8 is positioned at outer pump barrel 7, interior pump barrel 8 is provided with circular hole 10, and circular hole 10 is near oiling valve valve seat 12, and circular hole 10 is inclined hole;
Be provided with plunger 4 in outer pump barrel 7, on plunger 4, cover has the connecting rod 5 slided along plunger 4, and plunger 4 is the drum of " Jiong " font, the perforate of plunger 4 crown center, and the diameter of perforate is larger than connecting rod 5 external diameter, allows connecting rod 5 freely to pass through.Connecting rod 5 is disposed with rod collar 2, fixing pushing block 3 and Cone valve 6, fixing pushing block 3 external diameter is larger than plunger 4 crown center opening diameter, can promote plunger 4 descending, and fixing pushing block 3 is provided with breach, and Cone valve 6 is positioned at plunger 4; Cone valve 6 and fixing pushing block 3 gap ratio plunger 4 top thickness greatly, pass through the keying with valve to facilitate crude oil;
There is annular space 11 in interior pump barrel 8 and outer pump barrel 7, annular space 11 width is suitable with plunger 4 barrel thickness, and plunger 4 can just enter annular space 11, and realizes sealing.
The using method of a kind of oil well pump of the utility model is: rod collar 2 is connected with sucker rod, tubing coupling 1 is connected with oil pipe, time up, Cone valve 6 sealed plunger 4, and drive plunger 4 up, the spatial volume formed by plunger 4, outer pump barrel 7 and oiling valve valve seat 12 increases, pressure reduces, oiling valve valve ball 9 is backed down under pressure outside effect, and crude oil enters in outer pump barrel 7, realizes imbibition; Time descending, connecting rod 5 drive fixing pushing block 3 and Cone valve 6 descending, first remove the sealing between Cone valve 6 and plunger 4, outer pump barrel 7 is connected with oil pipe by tubing coupling 1, and connecting rod 5 continues descending, under the effect of fixing pushing block 3, force plunger 4 descending, pump barrel internal pressure rises, and crude oil enters oil pipe through plunger 4 and the gap of connecting rod 5, the breach of fixing pushing block 3, realizes discharge opeing.
Automatically cleaning: time descending, plunger 4 enters the annular space 11 of outer pump barrel 7 and interior pump barrel 8 formation, promoting crude oil circular hole 10 on interior pump barrel 8 in annular space 11 enters in interior pump barrel 8, and crude oil will clean oiling valve valve ball 9 and standing valve valve seat 12 after circular hole 10.Make crude oil in pump barrel also be in state of disturbance in descending process, the also not free settling such as mud, flour sand simultaneously.
A kind of oil well pump of the present utility model is provided with plunger 4, and oiling valve can be opened in time; Can open outlet valve by force makes crude oil enter in oil pipe smoothly simultaneously.Circular hole 10 on interior pump barrel 8, crude oil will clean oiling valve valve ball 9 and standing valve valve seat 12 after circular hole 10, prevent mud, flour sand, wax etc. in pump barrel sedimentation, attachment.
