Abstract

The utility model discloses a long stroke beam -pumping unit based on reciprocal lead screw mainly comprises base, motor, motor cabinet, production tree, bearing frame, reciprocal lead screw, round frame, frame, sucker rod, polished rod eye, wire rope, balcony, head sheave, belt and balancing weight, motor and reciprocal lead screw coaxial coupling, reciprocal lead screw surface be equipped with two pitch the same, revolve to opposite thread groove, reciprocal lead screw both ends with install the bearing bore interference fit on two bearing frames, reciprocal lead screw drives through surperficial thread groove and nut cooperation and comes and goes the frame and is reciprocal linear motion, the wire rope who comes and goes frame upper portion is connected with the polished rod eye that hangs the sucker rod, and the balancing weight is connected to the belt that comes and goes the frame lower part. The automatic machinery of realizing of lead screw commutates because reciprocate, and the reciprocal linear motion of round frame drives the sucker rod and does oil recovery action from top to bottom. The beneficial effect of the utility model as follows: beam -pumping unit stroke greatly increased can be makeed, the exploitation of deep well and viscous crude well crude oil is helped.

Description

A kind of long stroke pumping unit based on reciprocal leading screw
Technical field
The utility model relates to a kind of oil pumper, particularly a kind of long stroke pumping unit based on reciprocal leading screw.
Background technology
Oil pumper is extensive application in oil field development.Along with crude oil production, oil well depth is more and more darker, and traditional oil pumper stroke is difficult to meet deep-well crude oil production.Tradition oil pumper, due to walking beam and the restriction of round frame, is difficult to realize long stroke and recovers the oil.The utility model realizes mechanical commutation automatically based on reciprocal leading screw, and oil pumper stroke can be made greatly to increase, and contributes to deep-well and heavy oil wells crude oil production.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for prior art, provide a kind of long stroke pumping unit based on reciprocal leading screw, automatically realize mechanical commutation based on reciprocal leading screw, oil pumper stroke can be made greatly to increase, contribute to deep-well and heavy oil wells crude oil production.
Its technical scheme is: a kind of long stroke pumping unit based on reciprocal leading screw, primarily of base, motor, motor cabinet, production tree, bearing support, reciprocal leading screw, come and go frame, frame, sucker rod, polished rod eye, wire rope, balcony, head sheave, belt and balancing weight composition, described frame and production tree are arranged on base, and described motor is arranged on motor cabinet, and motor cabinet is fixed on bottom frame, and described electric machine main shaft is coaxially connected with reciprocal leading screw, and it is identical that described reciprocal leading screw surface is provided with two pitch, the thread groove that rotation direction is contrary, reciprocal leading screw two ends and the brearing bore interference fit be arranged on two bearing supports, described two bearing supports are fixed in frame, described reciprocal leading screw and the nut screw connection be arranged on round frame, described round frame side contacts with the smooth surface of frame, described round frame top is connected with wire rope, described wire rope is walked around the head sheave be arranged on balcony and is connected with polished rod eye, described polished rod eye hangs the sucker rod coaxial with the well head of production tree, described round frame lower end connects belt, connects balancing weight bottom described belt.
During oil pumper work, the reciprocal screw turns of driven by motor, reciprocal leading screw is driven by thread surface groove and nut screw connection and comes and goes frame rectilinear motion, when round frame moves to the reciprocal threads of lead screw end, counter motion can be driven by the thread groove that rotation direction is contrary, realize coming and going freely commutating of frame, come and go bottom frame and connect balancing weight by belt, come and go top of the trellis and rely on wire rope connecting with pumping rod, balancing weight and sucker rod realize load balance, coming and going frame linear reciprocating motion drives sucker rod to move up and down in the pit shaft of production tree, realizes the long stroke exploitation of crude oil.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
Accompanying drawing 2 is partial schematic diagrams of the present utility model.
In upper figure: base 1, motor 2, motor cabinet 3, production tree 4, bearing support 5, bearing 5.1, back and forth leading screw 6, round frame 7, nut 7.1, frame 8, sucker rod 9, polished rod eye 10, wire rope 11, balcony 12, head sheave 13, belt 14, balancing weight 15.
Detailed description of the invention
1-2 is further described the utility model by reference to the accompanying drawings:
The utility model is primarily of base 1, motor 2, motor cabinet 3, production tree 4, bearing support 5, reciprocal leading screw 6, come and go frame 7, frame 8, sucker rod 9, polished rod eye 10, wire rope 11, balcony 12, head sheave 13, belt 14 and balancing weight 15 form, described frame 8 and production tree 4 are arranged on base 1, and described motor 2 is arranged on motor cabinet 3, and motor cabinet 3 is fixed on bottom frame 8, described motor 2 main shaft is coaxially connected with reciprocal leading screw 6, and it is identical that described reciprocal leading screw 6 surface is provided with two pitch, the thread groove that rotation direction is contrary, reciprocal leading screw 6 two ends and the bearing 5.1 endoporus interference fit be arranged on two bearing supports 5, described two bearing supports 5 are fixed in frame 8, described reciprocal leading screw 6 coordinates with the nut 7.1 be arranged on round frame 7, described round frame 7 side contacts with the smooth surface of frame 8, described round frame 7 top is connected with wire rope 11, described wire rope 11 is walked around the head sheave 13 be arranged on balcony 12 and is connected with polished rod eye 10, described polished rod eye 10 hangs the sucker rod 9 coaxial with the well head of production tree 4, described round frame 7 lower end connects belt 14, connects balancing weight 15 bottom described belt 14.
During oil pumper work, motor 2 drives reciprocal leading screw 6 to rotate, reciprocal leading screw 6 is coordinated with nut 7.1 by thread surface groove and drives round frame 7 rectilinear motion, when round frame 7 moves to the reciprocal leading screw 6 screw thread end, counter motion can be driven by the thread groove that rotation direction is contrary, realize coming and going freely commutating of frame 7, come and go bottom frame 7 and connect balancing weight 15 by belt 14, come and go frame 7 top and rely on wire rope 11 connecting with pumping rod 9, balancing weight 15 and sucker rod 9 realize load balance, coming and going frame 7 linear reciprocating motion drives sucker rod 9 to move up and down in the pit shaft of production tree 4, realize the long stroke exploitation of crude oil.
The beneficial effects of the utility model are: provide a kind of long stroke pumping unit based on reciprocal leading screw, automatically realize mechanical commutation based on reciprocal leading screw, and oil pumper stroke can be made greatly to increase, and contribute to deep-well and heavy oil wells crude oil production.
