Description
Technical field:
The utility model relates to the short beam-pumping unit of a kind of beam balance, belongs to the oil recovery machiner technical field.
Background technology:
At present, there are many oil recovery machiners in each oil field, wherein big portion is the common beam oil pumper, balance mode mainly is a crank balance, or based on crank balance, adds the plural equilibrium of beam balance, and preceding walking beam length is suitable with stroke, existing problems are: because walking beam length is longer, increased the energy consumption of oil pumper, improved cost for oil production.
The utility model content:
The utility model purpose provides the short beam-pumping unit of a kind of beam balance, and walking beam length before shortening reduces the work arm of force, has reduced the power consumption of oil pumper, has alleviated the weight of beam counterweight, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: the short beam-pumping unit of beam balance, comprise body frame, transmission mechanism, crank-link mechanism, horse head, short walking beam, transmission mechanism connecting crank linkage, crank-link mechanism connects short walking beam, horse head is arranged on an end of short walking beam, and body frame is hinged on the short walking beam between horse head and the crank-link mechanism.
The utility model is provided with walking beam leading screw and beam counterweight, and walking beam leading screw and beam counterweight are arranged on the other end of short walking beam.
Said transmission mechanism comprises motor, reducer, is arranged on the base; Crank-link mechanism comprises crank, crank-pin, connecting rod, is hinged on the short walking beam by tail bearing; Body frame is hinged on the short walking beam between horse head and the crank-link mechanism by middle (center) bearing.
The utility model has shortened work walking beam length, sets up the suspending weight that beam counterweight comes balance to recover the oil.
The utility model is lacked the preceding active length of walking beam, is 0.5 ~ 0.7 times of the preceding walking beam of same model conventional pumping unit, has reduced the oil pumper work arm of force, has also just reduced the power consumption of oil pumper;
The rear portion of the utility model weak point walking beam is provided with beam counterweight, owing to reduced the oil pumper work arm of force, has just alleviated the weight of beam counterweight, only by the polished rod load of beam counterweight with regard to energy balance polished rod.
Other structure of the present utility model, identical as base, motor, reducer, crank-pin, body frame, connecting rod, middle (center) bearing, horse head and tail bearing etc. with each structure of common beam oil pumper, crank has been cancelled the structure that balance weight is installed, or reducing crank counterbalance, balance of the present utility model is the balanced structure based on beam balance.
Walking beam leading screw of the present utility model is adjusted the diverse location of beam counterweight by adjusting the walking beam leading screw, adjusts the balance of oil pumper.
Advantage of the present utility model and effect: walking beam length before shortening, reduce the work arm of force, reduced the energy consumption of oil pumper, save cost for oil production, alleviated counterpoise simultaneously, can adopt beam counterweight is main balanced structure, reduced useless kinetic energy consumption, can also undergo technological transformation to the common beam oil pumper in addition, reduce energy consumption, reach the purpose of energy-saving and emission-reduction.
