Abstract
The utility model discloses a torsion spring adopted reverse rotation preventing structure for a screw pump driving device, relating to the technical field of oilfield oil pumping machines and particularly relating to improvement technologies of reverse rotation preventing structures for screw pump driving devices. The reverse rotation preventing structure comprises a screw pump driving device body (4), wherein a reverse rotation preventing structure pawl (1) and a reverse rotation preventing structure ratchet (2) are mounted on the body (4), and the end part of the reverse rotation preventing structure pawl (1) is matched with ratchet teeth of the reverse rotation preventing structure ratchet (2). The reverse rotation preventing structure further comprises a torsion spring (3), wherein the torsion spring (3) is mounted on a rotary pin shaft of the reverse rotation preventing structure pawl (1), one end of the torsion spring (3) is fixed on the body (4), and the other end of the torsion spring (3) is fixedly connected with the reverse rotation preventing structure pawl (1). The torsion spring adopted reverse rotation preventing structure for the screw pump driving device is used for solving the problem that reverse rotation preventing is in failure caused by the fact that a spring of the existing reverse rotation preventing structure for the screw pump driving device can not enable the pawl to be promptly snapped in the ratchet teeth during shutdown.
Description
Technical field
The utility model relates to the oil-field oil pumper technical field, is specifically related to the improvement technology of the anti-reverse-rotation structure of driving unit on screw pump.
Background technique
Pumping unit is one of visual plant in petroleum production, and its Main Function is by sucker rod, oil well pump, and the crude oil in shaft bottom is risen on ground.At present, the oil field adopts screw pump as pumping unit more, and screw pump motor power energy-saving effect exceeds 1/3rd of the machine of kowtowing, and the oil pumping amount of screw pump is also large than the machine of kowtowing.
Screw pump is to rely on the pump housing and the formed engagement spatial volume of screw rod to change and the mobile rotary pump of carrying liquid or making it supercharging.Screw pump is divided into helical rotor pump, two screw pump and three screw pump etc. by the screw rod number.When the active bolt rotary, drive and to rotate together with the driven screw rod with its engagement, the screw rod engagement spatial volume of suction chamber one end increases gradually, pressure decreased.Liquid enters the engagement space under differential pressure action, when volume increases to maximum and when forming a Seal cage, liquid is just moving in Seal cage one by one continuously vertically, until discharge side one end.At this moment the screw rod of discharge side one end engagement spatial volume is dwindled gradually, and liquid is discharged.Flow and the pressure pulse of screw pump are very little, and noise and vibration is little, and suction capacity is arranged, but screw rod processing is more difficult.Pump has single-suction and two kinds of structures of double-sucking type, but helical rotor pump only has single-suction.Pump must be worn safety valve (helical rotor pump needn't be worn), makes delivery side of pump pressure surpass admissible value and damages pump or prime mover to prevent from stopping up as discharge tube for a certain reason.
As shown in Figure 1; the spring that the anti-reverse-rotation structure of existing driving unit on screw pump uses is extension spring; after long-time the use; fatigue failure due to spring self; the impact of the factor of natural environment such as upper wind and frost sleet; some springs can not make ratchet in time snap in hook tooth when shutting down, and cause anti-reverse malfunctioning.
Summary of the invention
The utility model provides the anti-reverse-rotation structure of the driving unit on screw pump that adopts torsion spring; the spring that the utility model has solved the anti-reverse-rotation structure of existing driving unit on screw pump can not make ratchet in time snap in hook tooth when shutting down, and causes anti-reverse malfunctioning problem.
For addressing the above problem, the utility model adopts following technological scheme: the anti-reverse-rotation structure that adopts the driving unit on screw pump of torsion spring, the body 4 that comprises driving unit on screw pump, anti-reverse-rotation structure ratchet 1 and anti-reverse-rotation structure ratchet 2 are installed on body 4, and the end of anti-reverse-rotation structure ratchet 1 coordinates with anti-reverse-rotation structure ratchet 2 hook tooths; Also comprise torsion spring 3, torsion spring 3 is arranged on the rotating pin of anti-reverse-rotation structure ratchet 1, and torsion spring 3 one ends are fixed on body 4, and the other end of torsion spring 3 is fixedly connected with anti-reverse-rotation structure ratchet 1.
The Stainless Steel Wire diameter of described torsion spring 3 is 0.8-3.3 millimeters.Preferably: the Stainless Steel Wire diameter of described torsion spring 3 is 1.1-2.1 millimeters.
The utility model changes the spring of the anti-reverse-rotation structure use of driving unit on screw pump into torsion spring, has increased steel wire diameter, makes ratchet can snap in rapidly hook tooth when shutting down, and guarantees equipment operation installation.Torsion spring uses stainless steel material simultaneously, prevents because natural causes makes the spring corrosion.

Embodiment
The below is described in detail the utility model with best embodiment
As shown in Figure 2, adopt the anti-reverse-rotation structure of the driving unit on screw pump of torsion spring, the body 4 that comprises driving unit on screw pump is equipped with anti-reverse-rotation structure ratchet 1 and anti-reverse-rotation structure ratchet 2 on body 4, the end of anti-reverse-rotation structure ratchet 1 coordinates with anti-reverse-rotation structure ratchet 2 hook tooths; Also comprise torsion spring 3, torsion spring 3 is arranged on the rotating pin of anti-reverse-rotation structure ratchet 1, and torsion spring 3 one ends are fixed on body 4, and the other end of torsion spring 3 is fixedly connected with anti-reverse-rotation structure ratchet 1.The Stainless Steel Wire diameter of described torsion spring 3 is 1.7 millimeters.
It should be noted that at last: obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being amplified out thus or change still are among protection domain of the present utility model.
