Abstract
The utility method relates to a balancing device of a pumping rod directly-balanced type energy-saving pumping unit, mainly solving the problem of high electric energy loss of the traditional rod pumping unit. The balancing device is characterized in that a balancing rope (3) is connected at both sides of a rope hanger (1), bypasses pulleys (5) on two supports (4) and then is connected with a balancing block (6). The balancing device of pumping rod directly-balanced type energy-saving pumping unit has the characteristic of low electric energy loss.
Description
Technical field:
The utility model relates to the direct balance energy-saving type of oil recovery field, oil field machine-pumped oil well used oil pumper, especially sucker rod balance of well pumping unit device.
Background technology:
Along with Oilfield developing, machine-pumped oil well is more and more.Machine-pumped oil well ground lifting device generally adopts the sucker rod pumping machine.And existing sucker rod pumping machine the high problem of electric energy loss owing to the reasons in structure ubiquity, and then increases cost for oil production, has influenced the recovery ratio of oil well, has restricted Oilfield developing.
The utility model content:
In order to solve the high problem of existing sucker rod pumping dynamo-electric energy loss, the utility model provides the direct balance energy-saving type of a kind of sucker rod balance of well pumping unit device, and the direct balance energy-saving type of this sucker rod balance of well pumping unit device has the low characteristics of electric energy loss.
The technical solution of the utility model is: the direct balance energy-saving type of this sucker rod balance of well pumping unit device comprises the polished rod eye on the polished rod, and the polished rod eye both sides are connected with balance rope, and balance rope is walked around the two stands top sheave and is connected with balance weight.
The utlity model has following beneficial effect: the direct balance energy-saving type of this sucker rod balance of well pumping unit device is because employing is connected with balance rope in the polished rod eye both sides, balance rope is walked around the two stands top sheave and is connected with optimizing structure of balance weight, utilize the balance weight principle to directly act on the sucker rod, the characteristic of gross weight balance on balance weight and the sucker rod, make and carry out 100% potential energy conversion between balance weight and the sucker rod, the balanced action of balance weight is separated with oil pumper, make the big reduction of power of motor of the direct balance energy-saving type of sucker rod balance of well pumping unit device, finally realize energy saving purposes.And it is simple in structure.The direct balance energy-saving type of this sucker rod balance of well pumping unit device has the low characteristics of electric energy loss thus.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
1-polished rod eye among the figure, 2-polished rod, 3-balance rope, 4-support, 5-pulley, 6-balance weight.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, the direct balance energy-saving type of this sucker rod balance of well pumping unit device comprises the polished rod eye 1 on the polished rod 2, and polished rod eye 1 is fixedly connected on the polished rod 2 by elevator.Polished rod eye 1 both sides hinge has balance rope 3, polished rod eye 1 both sides are fixed with the support 4 that is used to support, well head two side stands 4 just, both sides, support 4 upper end are connected with and are used for the pulley 5 of balance rope 3 in last rotation, balance rope 3 adopts wire rope, balance rope 3 is walked around two stands 4 top sheaves 5 and is connected with balance weight 6, and balance weight 6 weight approach whole sucker rod up stroke weight, tends to balance under the external force effect not having.
Operating principle: the direct balance energy-saving type of this sucker rod balance of well pumping unit device is applicable to that major part has on the bar machine-pumped oil well, as beam pumping unit, tower-type pumping unit etc.When the sucker rod upstroke, because balance weight 6 weight approach whole sucker rod up stroke weight, and directly act on sucker rod, as long as to some external force, balance just conversion rises, and can drive the oil well pump lifting with less power of motor thus.When the sucker rod down stroke, because balance weight 6 weight approach whole sucker rod up stroke weight, and directly act on sucker rod, sucker rod can descend automatically, balance weight rises simultaneously, the potential energy of sucker rod is converted into the potential energy of balance weight, straight line when this energy transforms, one of percentage hundred.As long as to some external force, balance just conversion descends, and it is descending to drive oil well pump with less power of motor.With existing 10 type beam pumping units is example, and 10 type beam pumping unit powers of motor are 37 kilowatts, 888 kilowatts of power consumptions in 24 hours.And the direct balance energy-saving type of this sucker rod balance of well pumping unit device power of motor is 18 kilowatts, 432 kilowatts of power consumptions in 24 hours, in view of this direct balance energy-saving type of this sucker rod balance of well pumping unit device economize on electricity reaches about percent 50, is to recover the oil and reduced cost greatly in the oil field.
