Abstract
The invention discloses a dirt removal protection device for an underground pumping unit, which comprises an outer pipe, a connection rod, adapters arranged at the two ends of the outer pipe and a positioning nut; a dirt removal device is arranged between the adapter close to one end of an oil well pump and the positioning nut; the dirt removal device comprises a scraping ring which is sleeved on the connection rod; scraping blades are arranged at the two ends of the scraping ring; and a dirt discharge slot is formed on the wall of the outer pipe opposite to the scraping ring. Due to the dirt removal device arranged between the adapter close to one end of the oil well pump and the positioning nut and a structure capable of automatically shrinking inwards arranged on the scraping ring, the scraping of dirt on a connection shaft is realized andfit between the surfaces of the shaft and the hole after abrasion is well ensured; moreover, the shrinking member is made from specific material, and therefore the corrosion resistance and high temperature resistance of the components are improved.
Description
Technical field
The present invention relates to a kind of scrubbing protective device of oil recovery equipment, particularly a kind of underground oil production machine.
Background technology
Because the inclined shaft in oil field is many; traditional machine of cracking between the teeth exists that energy loss is big, pull bar is disconnected is easily rubbed; and the friction of oil pipe and pull bar causes the situation of pipeline rupture leakage of oil; therefore domestic manufacturer is studying the underground oil recovery linear electric motors that do not have sucker rod energetically; ancestral petroleum fluid contains a large amount of silt and magnetic conduction thing; and contain weak acid and weak base in the fluid, if there is not protective device, will produce following unfavorable condition:
1, the surface of motion does not have lubrication oil mutually, the coefficient of friction height, and friction is big, quick abrasion
2, silt will flow into and cause rough surface, wearing and tearing to accelerate between the mover of motor and stator
3, the magnetic conduction thing is adsorbed on the sand card that causes on the mover that contains magnet easily, finally causes carrying well because of the motor cisco unity malfunction waste great amount of manpower and material resources and financial resources
4, contain of the damage of the fluid of weak acid and weak base to the motor key; Be corroded as part coating, magnet gets rusty and causes magnetic property to reduce, and motor electric power reduces
5, the easy fouling of the connecting rod of oil pump and motor and stationary part, the knot cured, result in blockage.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned existing problems, to provide a kind of scrubbing protective device that intercepts the underground oil production machine of oil extraction operation face silt, dustiness inflow motor internal.
On this basis, another purpose of the present invention provides and a kind ofly still can keep scrubbing protective device with the underground oil production machine of the good fit contact of relevant mating component at master driver after wearing and tearing.
On this basis, still a further object of the present invention provides a kind of scrubbing protective device with high temperature resistance, corrosion resistant underground oil production machine.
Technical scheme of the present invention is: a kind of scrubbing protective device of underground oil production machine; comprise outer tube, connecting rod, be arranged on the adapter and the setscrew nut at outer tube two ends; between near the adapter of oil well pump one end and setscrew nut, be provided with decontamination apparatus; described decontamination apparatus comprises scraping ring; described scraping ring is set on the connecting rod; be provided with at the two ends of a scraping ring and scrape sword, scraping ring over against the outer tube wall have the blowdown slotted eye.
Further: above-mentioned scraping ring vertically ring wall have some avoiding hollow grooves, the opening direction of described two adjacent avoiding hollow grooves is opposite, is provided with at least two contractibilities on the excircle of scraping ring, the ring surface of scraping that contractibility is installed in correspondence is provided with concave arc.
Again further: above-mentioned contractibility is elastic caoutchouc circle or a corrosion resisting elastic metal guiding principle silk corrosion-resistant, high temperature.
The present invention because adopted the decontamination apparatus that is provided with between near the adapter of oil well pump one end and setscrew nut and on scraping ring, be provided with automatically in the structure of contraction, both realized striking off to dustiness on the connecting axle, guaranteed good the cooperating in surface between wearing and tearing rear axle and hole again, in addition, contractibility adopts specific material, has improved corrosion-resistant, the high temperature resistance of parts.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the scraping ring structural representation;
Fig. 3 is scraping ring of the present invention and connecting rod assembling stereogram.
The specific embodiment
The present invention such as Fig. 1, Fig. 2, shown in Figure 3; a kind of scrubbing protective device of underground oil production machine; comprise outer tube 1, connecting rod 2, be arranged on the adapter 3 and the setscrew nut 4 at outer tube 1 two ends; between near the adapter 3 of oil well pump one end and setscrew nut 4, be provided with decontamination apparatus; described decontamination apparatus comprises scraping ring 5; described scraping ring 5 is set on the connecting rod 2, be provided with at the two ends of a scraping ring 5 and scrape sword 51, scraping ring 5 over against the outer tube wall have blowdown slotted eye 11.
The above-mentioned scraping ring 5 set sword 51 at least one end ecto-entads of scraping are a wedge angle.Be provided with terrace 41 at above-mentioned setscrew nut 4 near scraping ring 5 one sides, the external diameter of described terrace (41) is less than the external diameter of scraping ring (5).Last scraping ring 5 is that copper alloy or nonmetals are made.Above-mentioned scraping ring 5 vertically ring wall have some avoiding hollow grooves 52, the opening direction of described two adjacent avoiding hollow grooves 52 is opposite, is provided with at least two contractibilities 6 on the excircle of scraping ring 5, scraping ring 5 surfaces that contractibility 6 is installed in correspondence are provided with concave arc 53.Above-mentioned contractibility 6 is elastic caoutchouc circle or a corrosion resisting elastic metal guiding principle silk corrosion-resistant, high temperature.
Further instruction of the present invention is, decontamination apparatus is installed in the inside of outer tube 1, and be positioned between adapter 3 and the setscrew nut 4, connecting rod 2 passes the endoporus of decontamination apparatus and does back and forth (up and down) motion, because adapter 3 is connected to the lower end of oil well pump, so silt and magnetic conduction thing etc. thereof derive from adapter 3 near decontamination apparatus one side, when connecting rod 2 motions, dustiness on the axle is fixed on the setscrew nut 4 and scrapes sword 51 by scraping ring 5 end faces and strike off, and dustiness drops on the step surface 41 of setscrew nut 4 and outwards discharges from the blowdown slotted eye of outer tube 1.The wall thickness of above-mentioned scraping ring 5 is reasonable in design and from one end to the other side open avoiding hollow groove 52 on circumference, above-mentioned two adjacent avoiding hollow groove directions are opposite, make this part become one can radial compression part, be processed with arc groove 53 on scraping ring 5 excircles, in addition, assembling the contractibility 6 that inwardly shrinks in the arc groove on scraping ring 5 excircles, this contractibility 6 makes scraping ring 5 remain the state of inside contraction, thereby plays the effect that silt and other magnetic conduction thing are gone up in connecting rod 2 surfaces of striking off.
