Description
Technical field
This device is established and is related to a kind of oil pumper change torque startup running gear, is used in beam pumping unit, solves the problem of oil pumper low load with strong power, improves the operating efficiency of motor, realizes purpose of energy saving.
Background technology
The oil pump energy-saving device roughly can be divided into electrical machine energy-saving, become structure energy-saving, the weighing apparatus mode that flattens is energy-conservation and becomes the kind of drive etc. from energy-saving principle.Wherein, the 3 kinds of power save modes in back are the power save modes at beam pumping unit frame for movement, but there is a significant disadvantages in the mode that changes oil pumper frame for movement, must transform oil well, cost height not only, seeing from actual energy-saving effect neither be very desirable.
The reason that this phenomenon of oil pumper " low load with strong power " occurs is to be that oil pumper all is that band carries startup when starting, moment of inertia is bigger, the oil field is smooth in order to start when the apolegamy motor, do not influence production, general by maximum starting torque apolegamy motor, and oil pumper when starting the back operate as normal average torque compare lowlyer with peak torque, so power input to machine only has 1/3rd of rated power, this is the main cause that causes " low load with strong power ".Secondly, the oil field considers that oil well condition is unusual when the apolegamy motor, during as sand card wax deposition, reason startup difficulty is not burnt motor, when becoming big because of reasons such as well workover load, the oil well load frequently do not change motor, and artificially increased the power of motor allowance, aggravate " low load with strong power " this phenomenon.
Present operation technique:
1, oil pumper coupler transmission system, fluid coupling be a kind of be medium with liquid, transmit the device of energy by the variation of the liquid moment of momentum, gear drive has been introduced on basis at the oil pumper fluid coupling, and application specific gear reduction unit, change the horizontal transmission of motor into vertical transmission, motor output shaft can no longer bear radially adhesive tape pulling force like this, realized pure torsion output, fluid coupling can be realized soft start, this scheme advantage is soft, and shortcoming is that fluid coupling exists energy loss.
2, install the reduction starting power scheme that frequency converter carries out the rod-pumped well motor of soft start additional, by prolonging start-up time, make the motor start-up characteristic variations, realizing the purpose that starting power and installed power reduce. site test results shows and can effectively reduce the installed power of oil pumper by changing the electrical characteristics of actuator.
This scheme advantage is to adopt motor to transfer ginseng, change swabbing parameter, and shortcoming is the motor low rate start, but corresponding moment of torsion is difficult to raising, so the soft start DeGrain.
3, at motor output shaft the bigger accumulator of dynamic moment of inertia is installed, the accumulator flywheel can rotate with motor, and rely on its bigger dynamic moment of inertia energy of handling up, at flywheel shaft clutch is housed, rise and take out preceding elder generation with its disconnection, treat to hang again after the oil pumper stable working and close clutch, flywheel is devoted oneself to work.This device advantage is to realize soft start, but uses clutch and a big flywheel, complex structure.
Summary of the invention
