Described rotatingshaft 201 is made by wear-resisting, withstand voltage class material.
Oiling valve of the present invention connects a standing valve cell cube 19 again by following box cupling 18, this standing valve cell cube 19 links to each other with joint 20 again, described standing valve structure is referring to Fig. 5, comprise a camshaft 1901 and be nested with thereon ball valve 1903, with the valve seat 1904 of joint bolt, have oblique keyway 1906 on the camshaft 1901, the standing valve 1903 that is nested with thereon is standing valve hemisphere, is equipped with felt brush 1908 on the valve seat 1904.Felt brush 1908 is fixed on the valve seat 1904 by a double-screw bolt 1905; The hemispheric standing valve axially has cavity, the upper cavity aperture is complementary with the double-screw bolt 1905 that is fixed on the valve seat 1904, lower chamber aperture and camshaft 1901 are complementary, and leave cavity volume and be placed in the needle bearing 1902 of the double-screw bolt head end on camshaft 1901 head ends and the valve seat and spring 1907 therebetween with ccontaining branch.
Design principle of the present invention:
A. plunger revolve the oar thruster: at plunger bottom, its following outer each side all is shaped on can form under oil stream impacts turns round the moment of torsion wire casing of refusing, and stoste is at first given its impact force when plunger is descending, and plunger is rotated voluntarily; Work as stoste in addition and enter in the plunger cavity, stoste produces moment of torsion under its left-handed angle helix groove effect, promotes the plunger rotation.
B. the universal rotor of plunger: be the top that is contained in plunger, as long as give its power its just rotate.
C. the contract ring that rises of carbon fiber is three lobes, mutually the joint of inclined-plane socket and and the design of skidway hole gradient, making contracts to rise come what may can both reach the effect that requires of sealing.
D. according to the rule of oil well pump utilization, go out plunger when descending, the big more resistance in tube gap of plunger and pump barrel is more little, descending fast more principle, so when plunger is descending, the contract tube maximum that ring shrinks plunger and pump barrel along radial axis that rises of carbon fiber can reach 0.75mm, and plunger and gap between pump barrel when up is almost nil, is just reaching the functional requirement of integeral tube pumping pump.
Concrete working procedure of the present invention:
When plunger is up, hemisphere 1903 in the plunger internal fixation valve pocket is up along the cam path rotation of camshaft, stoste enters pump chamber by oil reservoir, at this moment, the stoste that enters plunger cavity promotes hemisphere column valve 7 and begins up, then three position-limited shafts move up thereupon, because position-limited shaft becomes up big and down small tapering with plunger axis, position-limited shaft contracts to rise at carbon fiber and upwards slides in the skidway hole of circular slide way body, promote three lobe carbon fibers contract rise the ring along the plunger radial spreading, up to contacting with the pump barrel inwall, this function result makes pump barrel and plunger cooperate for no gap.Being placed in the plunger the contract functional unit that rises of upper and lower carbon fiber makes the plunger active section keep gap-free sealed, improved pumping power, because contracting to rise to encircle, carbon fiber is the plasticity nonmetallic material, have good anti-corrosion, wear-resisting property, so that plunger has very big pumping power, make pump have high pump efficiency.
When plunger is descending, hemisphere column valve 7 beginnings in the plunger cavity are descending, and the position-limited shaft that drives the hemisphere column valve along carbon fiber contract rise up in the skidway hole of circular slide way body, this moment promote three lobe carbon fibers contract rise the ring along contracting in the plunger radial, plunger attenuates, and makes plunger descending, so simultaneously, the standing valve rotation is descending, and felt cleans down the sealing strip of valve seat, closes.Stoste is entered, the ram piston lower end revolve the left-handed angle of oar thruster helix groove, the coupled columns plug forms torsion, it is descending to promote the plunger rotation.Because the plunger body size is than the required standard δ 〉=1mm of pump barrel size less than conventional pumps, so plunger can be descending smoothly, plunger is descending smoothly, eliminates the non-directional wearing and tearing to sucker rod, prolonged the working life of pump, stopped holddown, sand card, sucker rod eccentric wear oil pipe.
