Abstract
The utility model discloses a motor which is matched with a pumping unit in an oil field, in particular a three-phase asynchronous motor for a pumping unit. The three-phase asynchronous motor for the pumping unit comprises a front frame, a front stator, a front rotor, a rear frame, a rear stator, a rear rotor and a rotating shaft. The front frame and the rear frame are fixedly connected as a whole. The front stator is arranged inside the front frame and the rear stator is arranged inside the rear frame. The rotating shaft is fixedly connected inside the frame via a front end cap, a rear end cap and a bearing. The front rotor and the rear rotor are arranged on the rotating shaft. Because two motors share a common shaft and can be started and used independently, single-motor or double-motor can be used randomly according to the oil sampling status. The motor can save large amount of electric power and improve economic benefits of oil fields.
Description
Technical field
The utility model is the matching used motor of a kind of oil-field oil pumper, particularly a kind of used for oil extractor threephase asynchronous.
Background technology
Threephase asynchronous of the prior art has only a cover stator and rotor sructure, in order to do power of electric motor bigger, just must will decide word and rotor is also done very greatly, so just makes to expend wealth by the huge benzene weight of whole motor.
Summary of the invention
The purpose of this utility model is in order to overcome existing threephase asynchronous whole motor when power is big defective that huge benzene is heavy that just seems, special invention is a kind of can to make the whole motor used for oil extractor threephase asynchronous lighter and handier, more power saving that seems under the situation of equal-wattage.
The purpose of this utility model realizes as follows: described used for oil extractor threephase asynchronous, comprise preceding support, preceding stator, preceding rotor, back support, back stator, back rotor and rotating shaft, preceding support is fixed in one with the back support, be provided with preceding stator in the preceding support, be provided with the back stator in the back support, rotating shaft is fixed in the support by front end housing and rear end cap and bearing, rotor and back rotor before rotating shaft is provided with.
Described rear end cap is provided with fan housing, is provided with fan in the fan housing.
The described motor that is made of preceding stator, preceding rotor, its phase sequence is U
1, V
1, W
1, by the motor that back stator, back rotor constitute, its phase sequence is U
2, V
2, W
2, two motors be connected to Y connection, i.e. U
1With W
2Connect V
1With U
2Connect W
1With V
2Connect.
The described power of motor that is made of preceding stator, preceding rotor is bigger; Less by the power of motor that back stator, back rotor constitute.
Good effect of the present utility model is as follows: owing to shared one of two motors, and the use of can starting shooting separately, so can use unit or two-shipper at random, may save a large amount of electric energy according to the oil recovery state, improve the economic benefit in oil field.

Embodiment
As shown in Figure 1, described used for oil extractor threephase asynchronous, support 1, preceding stator 2, preceding rotor 3, back support 4, back stator 5, back rotor 6 and rotating shaft 7 before comprising, preceding support 1 is fixed in one with back support 4, stator 2 before being provided with in the preceding support 1, be provided with back stator 5 in the back support 4, rotating shaft 7 is fixed in the support by front end housing 8 and rear end cap 9 and bearing 10, rotor 3 and back rotor 6 before rotating shaft 7 is provided with.
Described rear end cap 9 is provided with fan housing 11, is provided with fan 12 in the fan housing 11.
As shown in Figure 2, the described motor that constitutes by preceding stator 2, preceding rotor 3, its phase sequence is U
1, V
1, W
1, by the motor that back stator 5, back rotor 6 constitute, its phase sequence is U
2, V
2, W
2, two motors be connected to Y connection, i.e. U
1With W
2Connect V
1With U
2Connect W
1With V
2Connect.
The described power of motor that is made of preceding stator 2, preceding rotor 3 is bigger; Less by the power of motor that back stator 5, back rotor 6 constitute.
The electricity operation when the oil pumping load is light, is adopted unit operation.In oil pumping process, it is energy-conservation to adopt the mode that progressively starts by the oil pumping reservoir depth to realize, coaxial bi-motor starts simultaneously when oil place deep layer.When oil is pumped down to high bit, coaxial unit running.
