In order to solve the existing problem of entering of the impurity into the clearance between the mover and the stator in current technology and the easy occurrence of deadlocking of the mover and stator, the utility model comprises an upper elastic corrugated set and a lower elastic corrugated, the upper elastic corrugated set and a lower elastic corrugated set respectively set in the upper nozzle and lower nozzle and respectively set on the lateral of the motor mover; the upper head and the lower head of the upper elastic corrugated set respectively cementing connected with the external surface of motor mover above the motor stator and the upper head surface of the motor stator; the upper head and the lower head of the lower elastic corrugated set respectively cementing connected with the lower head surface and external surface of the motor mover under the motor stator. The upper elastic corrugated set and the lower elastic corrugated can elongate and fold repeatedly driven by the motor mover; through the upper elastic corrugated set and the lower elastic corrugated can realize the sealing of the internal motor, consequently prevent the entering of sand, oil pollution, fouling tablet and other impurity into the clearance between the mover and the stator, with the aim of sticking prevention achieved.
Description
Technical field
The utility model relates to a kind of oil immersion line motor.
Background technology
Reciprocating type oil-immersed pump utilize oil immersion line motor in the down-hole reciprocating motion of direct actuation plunger formula oil well pump finish pumping, it has cancelled oil pumper, sucker rod and deceleration, changement, reduce the one-time investment and the energy consumption of oil production equipment, reduced the cost of oilfield exploitation effectively.The mover of existing oil immersion line motor moves reciprocatingly in stator, between mover and stator certain clearance arranged radially, and directly contact with fluid, add the effect of electromagnetic force, impurity such as sand in the fluid, greasy dirt, dirty sheet are entered in the gap of mover and stator, be easy to take place the stuck and problem that can not move of mover and stator.
The utility model content
For solving the sand in the existing in prior technology fluid, greasy dirt, impurity such as dirt sheet enter in the gap of mover and stator, be easy to take place the stuck and problem that can not move of mover and stator, the utility model provides a kind of sand control oil immersion line motor, it comprises motor stator 1, electric mover 2, motor coil 3, upper connecting tube 4 and lower linking tube 5, upper connecting tube 4 and lower linking tube 5 be set in the outside of electric mover 2 and respectively with motor stator 1 on, the lower end is fixedly connected, it also comprises elastic corrugated cover 6 and following elastic corrugated cover 7, and upward elastic corrugated cover 6 and following elastic corrugated cover 7 are separately positioned in upper connecting tube 4 and the lower linking tube 5 and are set on the outside of electric mover 2; The described upper and lower end of elastic corrugated cover 6 is connected by sealing with the outer surface of the electric mover 2 of motor stator 1 top and the upper surface of motor stator 1 respectively; The upper and lower end of described down elastic corrugated cover 7 is connected by sealing with the outer surface of the electric mover 2 of the lower surface of motor stator 1 and motor stator 1 below respectively.Electric mover 2 of the present utility model is gone up elastic corrugated cover 6 and elastic corrugated cover 7 can be repeatedly under the drive of electric mover 2 down elongation and folding in motor stator 1 during reciprocating motion; Can realize the sealing of motor internal by last elastic corrugated cover 6 and following elastic corrugated cover 7, thereby impurity such as sand, greasy dirt, dirty sheet can not be entered in the gap of mover and stator, reach the purpose of motor anti-sticking.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Embodiment
Embodiment one: (referring to Fig. 1) present embodiment is made up of motor stator 1, electric mover 2, motor coil 3, upper connecting tube 4, lower linking tube 5, last elastic corrugated cover 6 and following elastic corrugated cover 7, upper connecting tube 4 is set in the outside of electric mover 2 with lower linking tube 5 and fixedlys connected with the upper and lower end of motor stator 1 respectively, and upward elastic corrugated cover 6 and following elastic corrugated cover 7 are separately positioned in upper connecting tube 4 and the lower linking tube 5 and are set on the outside of electric mover 2; The described upper and lower end of elastic corrugated cover 6 is connected by sealing with the outer surface of the electric mover 2 of motor stator 1 top and the upper surface of motor stator 1 respectively; The upper and lower end of described down elastic corrugated cover 7 is connected by sealing with the outer surface of the electric mover 2 of the lower surface of motor stator 1 and motor stator 1 below respectively.
Embodiment two: the difference of (referring to Fig. 1) present embodiment and embodiment one is that it has increased last crimp head 8 and following crimp head 9, and described last crimp head 8 is threaded with the upper end of electric mover 2 and the upper end of last elastic corrugated cover 6 is installed between the composition surface of crimp head 8 and electric mover 2; Described crimp head 9 down is threaded with the lower end of electric mover 2 and the bottom of following elastic corrugated cover 7 is installed in down between the composition surface of crimp head 9 and electric mover 2; Described upper connecting tube 4 is threaded with the upper end of motor stator 1 and the bottom of last elastic corrugated cover 6 is installed between the composition surface of upper connecting tube 4 and motor stator 1; Described lower linking tube 5 is threaded with the lower end of motor stator 1 and the upper end of following elastic corrugated cover 7 is installed between the composition surface of lower linking tube 5 and motor stator 1.Other composition is identical with embodiment one with annexation.Because the particularity of applying working condition of the present utility model, go up elastic corrugated cover 6 and down elastic corrugated cover 7 aging, damaged frequency is too high; Between last crimp head 8 that present embodiment increases and following crimp head 9 and the motor stator 1 respectively employing be threaded, described upper connecting tube 4 and lower linking tube 5 also are threaded respectively with the upper and lower end of motor stator 1, and the upper and lower end that will go up elastic corrugated cover 6 and following elastic corrugated cover 7 respectively is fixed, be convenient to replace with elastic corrugated cover 6 and following elastic corrugated cover 7, can effectively guarantee the useful life of oil immersion line motor.
By last elastic corrugated cover 6 with down in the seal cavity of elastic corrugated cover 7 formed motor internals, fill liquid or gas as required.In addition, upper and lower end of elastic corrugated cover 6 and following elastic corrugated cover 7 described in the utility model also can be adopted and is adhesively fixed, and uses needs as long as satisfy, all in the protection range of this patent.
