Abstract
The invention discloses a direct-drive beam pumping unit with a permanent-magnetic synchronous rotation motor for reducing mechanical loss and improving mechanical reliability. The direct-drive beam pumping unit comprises a horse-head, a walking beam, a connecting rod, a rocking arm and a driver and is provided with the permanent-magnetic synchronous rotation motor, wherein the permanent-magnetic synchronous rotation motor is connected with the driver; and an output shaft of the permanent-magnetic synchronous rotation motor is connected with the rocking arm. Because a gear box belt pulley is removed, the mechanical structure is simplified, the mechanical loss is reduced, and the mechanical reliability is improved; and the permanent-magnetic synchronous rotation motor has high efficiency to ensure that a system can save 20 to 60 percent of energy.
Description
Technical field
The present invention relates to pumping unit apparatus, especially is that the permanent-magnetic synchronous rotation motor of driving force directly drives beam pumping unit with the electric rotating machine.
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, has complex structure, and power consumption is big, and system effectiveness is low, the problem that maintenance cost is high.1), complex structure mainly show as:: electric rotating machine drives belt pulley by belt and rotates, and then by gear-box, rocking arm, connecting rod, walking beam, drives horse head and does rectilinear motion up and down, needs multiple device to cooperate and just can finish oil recovery; 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
In order to overcome above-mentioned defective, the invention provides a kind of permanent-magnetic synchronous rotation motor that reduces mechanical loss, raising Mechanical Reliability and directly drive beam pumping unit.
The present invention for the technical scheme that solves its technical problem and adopt is:
Direct-drive beam pumping unit with permanent-magnetic synchronous rotation motor, comprise horse head, walking beam, connecting rod, rocking arm and driver, be provided with permanent-magnetic synchronous rotation motor, described permanent-magnetic synchronous rotation motor is connected with driver, and the output shaft of permanent-magnetic synchronous rotation motor is connected with rocking arm.
Described rocking arm is connected with walking beam by connecting rod.
Described rocking arm is provided with counterweight.
The invention has the beneficial effects as follows: direct-drive beam pumping unit with permanent-magnetic synchronous rotation motor, be provided with permanent-magnetic synchronous rotation motor, permanent-magnetic synchronous rotation motor is connected with driver, and the output shaft of permanent-magnetic synchronous rotation motor is connected with rocking arm.Because cancellation gear-box belt pulley has been simplified frame for movement, has reduced mechanical loss, has improved Mechanical Reliability; Permagnetic synchronous motor efficient height can reach energy saving of system 20%-60% thus.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
