When the sucker rod upwards moves, the pressure oil in the energy accumulator pushes the piston, and energy is provided for the upward movement of the sucker rod.
Description
Technical field
The utility model relates to a kind of oil pumper, specifically a kind of energy saving type lightweight oil pumper.
Background technology
traditional well recovery machine drives lever reciprocating tractive sucker rod work by rocker-arm link.The mechanical energy of exporting by motor rises to certain height by sucker rod, and then sucker rod declines under the effect of self gravitation.In this course, by sucker rod, declined and the kinetic energy that produces is not utilized, caused the waste of energy.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of energy that can utilize sucker rod to decline and produce, the energy saving type lightweight oil pumper of minimizing energy dissipation.
The technical solution of the utility model is: a kind of energy saving type lightweight oil pumper, comprise can rotating motor, lifting gear, sucker rod, described motor can drive lifting gear motion, described lifting gear can drive sucker rod to move up and down; It also comprises the oil cylinder of sealing, in described oil cylinder, is provided with piston, and described piston is divided into upper cylinder half and lower cylinder by oil cylinder, and described lower cylinder is filled with hydraulic oil; Described sucker rod is fixedly connected with piston through the bottom surface of oil cylinder, and the top of described sucker rod is fixedly connected with lifting gear through the end face of oil cylinder, and the lower cylinder of described oil cylinder is connected with accumulator.
Described lifting gear is screw body, and the leading screw of described screw body is ball-screw.
Described energy saving type lightweight oil pumper also comprises the browpiece being arranged on well head, is provided with the support set being enclosed within on oil cylinder on described browpiece, and the top of described support set is provided with reduction box, and described motor drives screw body to move by reduction box; Reduction box comprises high speed shaft and slow-speed shaft, and described slow-speed shaft is the hollow shaft that screw body nut is installed; The leading screw of described screw body is hollow shaft, and leading screw is passed on the top of described sucker rod, and is fixed on the front end of leading screw, and the bottom of described sucker rod is connected with downhole pumping installation.
The front end of described screw body is provided with leading screw is carried out to spacing limit element, prevents that sucker rod from bumping against the top of screw body in screw mandrel uphill process.
The utility model has the advantages that: the energy storage by sucker rod is moved downward to generation, to accumulator, provides energy for sucker rod moves upward next time, has saved thus energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model energy saving type lightweight oil pumper.
The specific embodiment
As shown in the figure, a kind of energy saving type lightweight oil pumper, comprise can rotating motor 1, lifting gear, sucker rod 5, described motor 1 can drive lifting gear motion, described lifting gear can drive sucker rod 5 to move up and down; It also comprises the oil cylinder 3 of sealing, in described oil cylinder 3, is provided with piston 4, and described piston 4 is divided into upper cylinder half and lower cylinder by oil cylinder 3, and described lower cylinder is filled with hydraulic oil; Described sucker rod 5 is fixedly connected with piston 4 through the bottom surface of oil cylinder 3, and the top of described sucker rod 5 is fixedly connected with lifting gear through the end face of oil cylinder 3, and the lower cylinder of described oil cylinder 3 is connected with accumulator 6.
Described lifting gear is screw body, and the leading screw 11 of described screw body is ball-screw.
Described energy saving type lightweight oil pumper also comprises the browpiece 8 being arranged on well head, on described browpiece 8, be provided with the support set 9 being enclosed within on oil cylinder 3, the top of described support set 9 is provided with reduction box 7, and described motor 1 drives screw body to move by reduction box 7; Reduction box 7 comprises high speed shaft and slow-speed shaft, and described slow-speed shaft is the hollow shaft that screw body nut 2 is installed; The leading screw 11 of described screw body is hollow shaft, and leading screw 11 is passed on the top of described sucker rod 5, and is fixed on the front end of leading screw 11, and the bottom of described sucker rod 5 is connected with downhole pumping installation.
The front end of described screw body is provided with leading screw 11 is carried out to spacing limit element 10.
When screw mandrel 11 moves downward, sucker rod 5 moves downward thereupon, and piston 4 also moves downward, and pressure oil is pressed into accumulator 6.When sucker rod 5 moves upward with screw mandrel 11, the pressure oil that accumulator is 6 li promotes piston 4, moves upward energy to sucker rod 5 is provided.
