Description
Technical field
The utility model belongs to electric motors, is specifically related to oil field digitlization oil pumper special fan certainly cold type frequency converting speed regulating three-phase asynchronous electromotor.
Background technology
The digitlization oil pumper that current oil field uses configures common Series Motors, due to low speed poor radiation, cause electric machine temperature rise high, bury the hidden danger of motor damage, and configuration belt pulley cannot meet the requirement of adjusting jig frequency, therefore, jig frequency adjustment adopts the mode that frequency control and replacing motor pulley combine.Therefore digitlization oil pumper need configure 2 ~ 3 motor pulleys when dispatching from the factory, make tune jig frequency can not realize digitlization manipulation completely, have impact on the performance of digitlization oil pumper.On the other hand, general frequency-conversion and speed-regulation motor all adopts independently-powered cooling blower, there is not the problem that low speed temperature rise exceeds standard, also the requirement that digitlization oil pumper only configures a belt pulley can be realized, but because independent cooling fan is not by the impact of motor start and stop, continuous running, causes the increase of energy consumption.In addition, the independent cooling fan of frequency-conversion and speed-regulation motor need from the independent wiring of control cubicle (three-phase), thus make on-site installation and maintenance complicated.
Utility model content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art, there is provided a kind of oil field digitlization oil pumper special from fan cold type frequency converting speed regulating three-phase asynchronous electromotor, both can realize digitlization oil pumper and only configure a belt pulley to realize oil pumper fully digitalization manipulation, can realize again the better and longer service life of the performance of motor also can be fast convenient for installation and maintenance at the scene.
The technical scheme that the utility model adopts is: oil field digitlization oil pumper is special from fan cold type frequency converting speed regulating three-phase asynchronous electromotor, comprises stator, rotor, front end housing, rear end cap, terminal box, fan, fan housing.Described stator comprises hollow support and is fitted in has wound stator unshakable in one's determination in support, and it is unshakable in one's determination and press fit into the power transmission shaft of cast-aluminum rotor inner chamber unshakable in one's determination that described rotor comprises cast-aluminum rotor.Described have wound stator iron core to comprise the threephase stator winding that cylindrical stator is unshakable in one's determination and be embedded in stator slot.Described stator core has stator slot to embed electromagnetic wire, and described rotor core has rotor with cast aluminum.Terminal box is fixedly mounted on support, the two ends, left and right of support are fixedly connected with forward and backward end cap respectively, rotor is placed in bore of stator and is supported on front and back ends by forward and backward bearing and covers, and fan is fixedly mounted on power transmission shaft rear end, and fan housing is fixedly mounted on rear end cap.Its primary features is: according to the concrete technical requirement of oil field digitlization oil pumper motor used, and new design stator and rotor flute profile, stator and rotor slot fit is 48/44, for certainly fanning cold type frequency converting speed regulating three-phase asynchronous electromotor.
The beneficial effects of the utility model are: the utility model is applied to oil field digitlization oil pumper, can realize digitlization oil pumper and only configure a belt pulley, thus realize oil pumper fully digitalization manipulation; And the utility model, by the redesign to stator and rotor punching flute profile and stator and rotor core length and stator winding, improves the low speed thermal diffusivity of motor, avoid and adopt independent blower fan, it is more convenient to install, and consumes energy less.
