Abstract
The utility model relates to a pumping unit transmission component of single crank double-stroke flexible type, which is used for solving the problems that the pumping unit of the prior art has a low useful load percentage and high energy consumption and needs much initial investment. The utility model is characterized in that a strength haulage belt (6), of which an end socket is fixed to a bracket (5), is connected with a sealing pump piston through a fixed pulley (1), a moveable pulley (4), a fixed pulley (2) and a fixed pulley (3). The pumping unit power transmission device of single crank double-stroke flexible type has a high useful load percentage and low energy consumption and needs less initial investment.
Description
Technical field:
The utility model relates to the used transmission part of pumping unit, especially single-crank multiple-stroke flexible type pumping unit driving component in the oil recovery field, oil field.
Background technique:
Along with Oilfield developing, technology constantly develops, mechanical oil recovery equip ment from the beam pumping unit to the submersible electric pump, screw pump etc., of a great variety, to adapt to the needs of different productive lives.At present, the pumping unit that is used for artificial lift is based on beam pumping unit, is divided into conventional type beam pumping unit, prefix type beam pumping unit, out-phase type beam pumping unit and two horse head type beam pumping unit according to the difference of the structure of the crank quadratic crank mechanism of horse head.The pumping unit of this structural type is to swing up and down by walking beam to realize lifting well liquid, because of walking beam walking beam size and deadweight portion very big, so it is low to exist the useful load rate, power consumption is high, one-time investment is more, thereby has increased cost for oil production, is unfavorable for applying.
The model utility content:
Low in order to solve existing pumping unit driving component useful load rate, power consumption is high, the problem that one-time investment is more, the utility model provides a kind of single-crank multiple-stroke flexible type pumping unit driving component, this single-crank multiple-stroke flexible type pumping unit driving component has useful load rate height, it is low to consume energy, the characteristics that one-time investment is few.
The technical solution of the utility model is: this single-crank multiple-stroke flexible type pumping unit driving component comprises that the support upper end is fixed with two static pulley, static pulley that the support arm upper end is fixing and the fixing movable pulley of crank end, one termination is fixed on the powerful traction belt on the support, and powerful traction belt is walked around first static pulley, movable pulley, second static pulley and the 3rd static pulley successively and linked to each other with the canned pump piston.
The utlity model has following beneficial effect: this single-crank multiple-stroke flexible type pumping unit driving component is owing to take such scheme, use powerful traction to drive the purpose that flexible rod reaches the lifting of well liquid, because of powerful traction belt simple in structure, volume and deadweight are little, so just can improve the useful load rate, cut down the consumption of energy, reduced one-time investment, thereby reduced cost for oil production, helped applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-static pulley among the figure, 2-static pulley, 3-static pulley, 4-movable pulley, 5-support, the powerful traction belt of 6-.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this single-crank multiple-stroke flexible type pumping unit driving component comprises that support 5 upper ends are fixed with static pulley (1,2), static pulley 3 that the support arm upper end is fixing and the fixing movable pulley 4 of crank end, one termination is fixed on the powerful traction belt 6 on the support 5, and powerful traction belt 6 is walked around static pulley 1, movable pulley 4, static pulley 2 and static pulley 3 successively and linked to each other with the canned pump piston.Use powerful traction belt 6 to drive the purpose that flexible rods reach the lifting of well liquid, simple in structure because of powerful traction belt 6, volume and deadweight are little, so just can improve the useful load rate, cut down the consumption of energy, reduced one-time investment, thereby reduced cost for oil production, helped applying.
Claims (1)
1, a kind of single-crank multiple-stroke flexible type pumping unit driving component, comprise that support (5) upper end is fixed with static pulley (1,2), static pulley (3) that the support arm upper end is fixing and the fixing movable pulley (4) of crank end, it is characterized in that: a termination is fixed on the powerful traction belt (6) on the support (5), and powerful traction belt (6) is walked around static pulley (1), movable pulley (4), static pulley (2) and static pulley (3) successively and linked to each other with the canned pump piston.
