Abstract
A pumping rod torsional buffer for a screw pump is primarily used to resolve the problem that current pumping rod is apt to be broken. The utility model is characterized in that a cross mandrel (1) is positioned in a ladder cylinder in an outer cylinder (5), and a baffle ring (2) is fixed between the upper end of the outer cylinder (5) and a mandrel (1), the space between the bottom of mandrel (1) and the inner end of the outer cylinder (5) is sequentially provided with a piston (3) and a spring (4). The pumping rod torsional buffer of the utility model can completely eliminate the fatigue damage caused by the torsion resonance vibration, and has the feature of relieving resonance vibration.
Description
Technical field:
The utility model relates to the used screw pump sucker rod accessory in oil recovery field, oil field, belongs to screw pump sucker rod torsional damper.
Background technique:
Mechanical oil recovery is still the main method of current oil recovery, and screw pump is a kind of new mechanical oil production equipment, is fit to exploitation high viscosity, gassiness, contains husky crude oil; Variation along with the oil recovery situation, deep-well and inclined shaft constantly increase, the screw pump sucker rod bears bigger moment of torsion when operation, there is more serious torsional vibration simultaneously, aggravated the degree of fatigue of screw pump sucker rod, have the moment phenomenon that releases, causing breaks between the sucker rod takes off, grinds button, strip button and dropout, increase maintenance load, influence ordinary production, pump is burnt out when serious.
The utility model content:
Be prone to disconnected deficiency of taking off in order to overcome existing screw pump sucker rod, the utility model provides a kind of screw pump sucker rod torsional damper, this screw pump sucker rod torsional damper can be eliminated the fatigue ruption that is caused by torsional resonance fully, has the advantages that to eliminate torsional vibration.
The technical solution of the utility model is: this screw pump sucker rod torsional damper comprises urceolus, ladder cylindrical hole in the urceolus is built-in with " ten " font axle, intrinsic baffle ring between urceolus upper end and axle is equipped with piston and spring between axle bottom and urceolus the inner successively.
Above-mentioned spring can be metal spring, rubber spring or hydraulic spring.
The utlity model has following beneficial effect: because the urceolus in this screw pump sucker rod joint is built-in with axle, baffle ring, piston, spring, by the spiral connection torsional oscillation is converted to longitudinal vibration, pass through spring buffer, reach and reduce vibration, eliminate the damage that resonance brings, can eliminate the torsional vibration that the screw pump sucker rod produces effectively in running, avoid the disconnected phenomenon of taking off, reduce the workover workload, improved the efficient of screw pump.
Description of drawings:
Fig. 1 is a structure sectional view of the present utility model.
1-axle among the figure, 2-baffle ring, 3-piston, 4-spring, 5-urceolus.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in FIG., this screw pump sucker rod torsional damper comprises urceolus 5, the ladder cylindrical hole of urceolus 5 is built-in with " ten " font axle 1, axle 1 and urceolus 5 are connected by spiral, 1 intrinsic baffle ring 2 of urceolus 5 upper ends and axle, baffle ring 2 and urceolus 5 are by being threaded, axle 1 matches with baffle ring 2 and is threaded with sucker rod, be equipped with piston (3) and spring (4) successively between axle (1) bottom and urceolus (5) the inner, touch mutually with piston 3 axle 1 bottom, and spring 4 can be metal spring, rubber spring or hydraulic spring; Axle 1 and urceolus 5 are connected by spiral torsional oscillation are converted to longitudinal vibration, pass through spring buffer, reach and reduce vibration, eliminate the damage that resonance brings, can eliminate the torsional vibration that the screw pump sucker rod produces effectively in running, avoid disconnected and take off phenomenon, reduced the workover workload, improved the efficient of screw pump.
Claims (2)
1, a kind of screw pump sucker rod torsional damper, comprise urceolus (5), it is characterized in that: the ladder cylindrical hole in the urceolus (5) is built-in with " ten " font axle (1), intrinsic baffle ring (2) between urceolus (5) upper end and axle (1) is equipped with piston (3) and spring (4) between axle (1) bottom and urceolus (5) the inner successively.
2, screw pump sucker rod torsional damper according to claim 1, it is characterized in that: spring (4) can be metal spring, rubber spring or hydraulic spring.
