Abstract
The utility model relates to a pumping unit, and provides a beam pumping unit directly driven by a rotary motor. The beam pumping unit comprises the structure that a walking beam is movably connected to a bracket through a shaft; a horsehead is arranged at one end of the walking beam; a connecting shaft is arranged at the other end of the walking beam, and is connected with a connecting shaft on a rocker through a connecting rod; a weight balancing device is arranged at one end of the rocker; and the other end of the rocker is directly arranged on the power output shaft of the rotary motor. The utility model has the advantages of improving the mechanical reliability and lowering the maintenance cost and the running cost.
Description
Technical field
The utility model relates to a kind of oil rig.
Background technology
Beam pumping unit is widely used a kind of oil exploration equipment on the present oil field, and its rational structure makes it be fit to on-the-spot rugged environment, and is durable in use, has very strong vitality.But it normally adopts electric rotating machine to drive by deceleration device, complex structure, and power consumption is big, and system effectiveness is low, the maintenance cost height.The deficiency that existing scheme exists:
1) prior art complex structure;
2) efficient is low: gear drive and belt transmission all can cause the gearing loss;
3) poor reliability: belt pulley and gear-box reduce the reliability of system;
4) maintenance cost height: under the normal mode of occupation, all will change gear-box machine oil and belt every year.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art that a kind of reliability height is provided, energy-conservation electric rotating machine direct-drive beam pumping unit.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of electric rotating machine direct-drive beam pumping unit, be included on the support and be connected with walking beam by axle, one end of walking beam is provided with horse head, the other end of walking beam is provided with connecting axle, connecting axle is connected with connecting axle on the rocking arm by connecting rod, and an end of described rocking bar is provided with counter weight device, and the described rocking bar other end is set directly on the power output shaft of electric rotating machine.
Further, also include driver, described driver is electrically connected with described electric rotating machine.
The beneficial effects of the utility model are: improved Mechanical Reliability; Can reach energy saving of system 20%-30% thus.
Reduce maintenance cost: the maintenance of the machine of kowtowing to the effect that to the making regular check on of reducer, change oil, and the optimizing and revising and regularly replacing of belt pulley.As above said, owing to having adopted direct drive mode to save reducer and belt pulley, thereby make the maintenance of the machine of kowtowing simplify greatly, reduced the utilization cost.
When traditional machine of kowtowing used Asynchronous Motor Driving, the velocity of rotation of asynchronous machine was 750～1500 rev/mins, and the needed speed of the machine of kowtowing is 2～10 rev/mins, had therefore used reducer and driving belt to reach deceleration.The efficient of reducer and driving belt is about 0.76.Because the raising of control performance can make electric rotating machine satisfy the effect that the big commentaries on classics of low speed is refused now, has saved reducer and belt pulley thus, make the efficient that improves 20-30% become possibility.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 1, a kind of electric rotating machine direct-drive beam pumping unit, be included on the support 3 and be connected with walking beam 4 by axle 8, one end of walking beam 4 is provided with horse head 2, the other end of walking beam is provided with connecting axle 7, connecting axle 7 is connected with connecting axle 6 on the rocking arm 12 by connecting rod 9, and an end of described rocking bar 9 is provided with counter weight device 10, and described rocking bar 12 other ends are set directly on the power output shaft 5 of electric rotating machine 11.Also include driver 13, described driver 13 is electrically connected with described electric rotating machine 11.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
