detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in drawings, this directly drives oil pumper to comprise support 1, casing 2, slide rail cylinder 3, screw 4, ball screw 5, variable-frequency motor 6, gear 7 and side's card 8.Support 1 is connected on well head big four, and casing 2 is connected on support 1, and casing 2 is used for sealing ball screw 5 and sucker rod, while ensureing safety, plays sealing function.Axially sealing shroud is had in casing 2, sealing shroud isolates airtight ring cavity by casing 2, lubrication oil is had in airtight ring cavity, lubrication oil plays lubrication and cooling ball screw 5 and acts on, slide rail cylinder 3 is axially connected in casing 2, slide rail cylinder 3 bottom is built-in with secondary spring, and secondary spring ensures that ball screw 5 and sucker rod rise in cushioning effect in unexpected dropping process fast, and secondary spring design simultaneously also can play the effect of power-assisted lifting when upstroke starts.Slide rail cylinder 3 wall axially there are 3 strip holes, screw 4 is connected in the casing 2 of slide rail cylinder 3 upper end by bearing, , screw 4 can only be rotated can not move up and down, screw 4 is connected with ball screw 5 by screw thread, ball screw 5 is hollow shape, sucker rod can through ball screw 5 coupled, there is external screw thread outward, external screw thread combines with screw 4 internal thread, ball screw 5 is outer axially has 3 boss 9, boss 9 is placed in strip hole, ball screw 5 is placed restrictions on by boss 9, ball screw 5 can only be moved up and down, can not rotate, variable-frequency motor 6 is connected to casing 2 side, variable-frequency motor 6 axle is connected with gear 7, gear 7 is meshed with screw 4 external tooth, screw 4 and gear 7 speed reducing ratio are 1:5, ball screw 5 is connected with sucker rod by side's card 8, variable-frequency motor is connected with control cabinet inner control circuit.There is provided power by variable-frequency motor 6, change rotary motion into rectilinear motion by gear 7, screw 4 and ball screw 5, and drive sucker rod to pump, reach the object of lifting well liquid.
The course of work:
This directly drives oil pumper to control variable-frequency motor 6 switch and commutation by control cabinet inner control circuit, variable-frequency motor 6 rotation driven gear 7 rotates, gear 7 rotating band movable wire female 4 rotates, screw 4 rotates and drives ball screw 5 to move up and down, ball screw 5 moves up and down and drives sucker rod in ball screw 5 to move up and down, and then realize oil well pump and pump, well liquid is lifted to ground the most at last.When sucker rod rising top dead-centre, control variable-frequency motor 6 by control cabinet inner control circuit and commutate, variable-frequency motor 6 reverses, and ball screw 5 drives sucker rod to move down; When sucker rod decline bottom dead centre, control variable-frequency motor 6 by control cabinet inner control circuit and commutate, variable-frequency motor 6 rotates forward, and ball screw 5 drives sucker rod to move up, and such reciprocation cycle realizes the object of well liquid lifting.
This directly drives oil pumper to belong to a kind of oil field special machine oil production equipment, and this directly drives oil pumper to be made up of variable-frequency motor 6, ball screw 5 and relevant lubricating system.Coaxially erect in the upper end of connection bracket and be fixed with slide rail, with slide rail axes coincide, ball screw 6 and screw 4 are installed.Drive unit by variable-frequency motor 6 output shaft by gear 7 be fixed together with screw 5.Utilize variable-frequency motor 6 by ball screw 6 system Direct driver sucker rod, transmission link is few, effectively saving equipment cost, improving system effectiveness and system without exposing movement parts, the feature such as safe and reliable to operation, this directly drive oil pumper have manufacture, transport and easy for installation, cost is low; Few easy workout part, can improve the system cloud gray model life-span, save energy consumption; Be convenient to maintain and repair methods, reduce the advantage of running cost.
This directly drives oil pumper to have directly driving, and transmission efficiency is high.Drive disk assembly is few, and motor is connected with ball screw by gear, can realize the conversion from rotary motion to straight reciprocating motion, machine driving route is short, efficiency is high, reduce autophage power, improve mechanical efficiency and system effectiveness, thus save mass energy.
It is low that this directly drives oil pumper to have Product processing manufacture, transport and installation cost.Relative to the huge profile of traditional beam pumping unit, the present invention considerably reduces the metal consumption of processing, and meanwhile, due to less volume, transport of being more convenient for also directly can be installed on well head rapidly, the cost reducing production, transport and install.
This directly drives oil pumper to have the few easy workout part of equipment, and operational reliability is high.Be conducive to the application life of increase equipment, be also convenient to the maintain and repair methods in manufacturing process simultaneously, reduce operation and maintenance cost.
This directly drives oil pumper to have directly driving pumping unit apparatus and is directly installed on well head, so do not need the foundation constructions such as concrete, the very little requirement reduced oil well surrounding environment of shaft mouth operation area, saves a large amount of manpowers and material resources.
