Abstract
The utility model provides a submersible motor stator including a motor housing (1), an insulation end plate (2), a snap ring (3), a stator sheet (5) and a stator copper sheet (6). A snap ring groove (7) is arranged in an inner wall of the motor housing (1). The stator copper sheet (6), the stator sheet (5) and the stator end plate (4) are arranged in the motor housing (1) successively and are fixed through the snap ring (3) disposed on an outer end face of the stator end plate (4). The snap ring (3) is disposed in the snap ring groove (7). The insulation end plate (2) is disposed on an outer end face of the snap ring (3). The insulation end plate is in an integral design. The submersible motor stator in the utility model has advantages of simple structure and convenient processing. By adopting the submersible motor stator in the utility model, the insulation performance of a submersible motor working in a high temperature environment is improved, and the service lifetime of the submersible motor stator is prolonged.
Description
Technical field
The utility model relates to a kind of submersible electric machine with oil, particularly a kind of submersible electric machine with oil stator.
Background technology
At present; The stator of submersible electric machine with oil mainly comprises motor case, insulating end plate, snap ring, stator end plate, stator piece and stator copper sheet; When assembling; Stator copper sheet, stator piece and stator end plate are pressed between the annular groove of motor case two ends successively, fix with snap ring again, the insulating end plate of packing at last.Wherein insulating end plate is to realize the requisite part of electrical machine insulation, and the quality of its quality and performance directly influences the insulation property of submersible electric machine with oil.The insulating end plate heatproof of present domestic use is generally below 180 ℃, and the employing multi-disc is adhered, utilizes viscose glue that several end plates are bonded together; Form layer structure; When the insulating end plate of this kind structure was used for temperature and is higher than 180 ℃ environment, viscose glue will lose adhesive property and cause its insulation property to be seriously influenced, thereby makes that the insulation property of whole submersible electric machine with oil are poor; Cisco unity malfunction, reduce useful life greatly.
The utility model content
The purpose of the utility model just provides the submersible electric machine with oil stator that a kind of insulation property are high, the life-span is long.
The purpose of the utility model is to realize through such technical scheme; A kind of submersible electric machine with oil stator; Comprise motor case, insulating end plate, snap ring, stator end plate, stator piece and stator copper sheet, the inwall of motor case is provided with annular groove, and said stator copper sheet, stator piece and stator end plate are successively set in the motor case; And fix through the snap ring that is arranged on the stator end plate outer face; Said snap ring is arranged in the annular groove, and said insulating end plate is arranged on the outer face of snap ring, and said insulating end plate is the integral type setting.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to process, adopt it to improve the insulating properties that submersible electric machine with oil is worked under 250 ℃～300 ℃ hot environment, prolonged submersible electric machine with oil useful life.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the zoomed-in view of A portion among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these execution modes; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: like Fig. 1, shown in 2; A kind of submersible electric machine with oil stator; Comprise motor case 1, insulating end plate 2, snap ring 3, stator end plate 4, stator piece 5 and stator copper sheet 6, the inwall of motor case 1 is provided with annular groove 7, and said stator copper sheet 6, stator piece 5 and stator end plate 4 are successively set in the motor case 1; And it is fixing through the snap ring 3 that is arranged on stator end plate 4 outer faces; Said snap ring 3 is arranged in the annular groove 7, and said insulating end plate 2 is arranged on the outer face of snap ring 3, and said insulating end plate 2 is the integral type setting.
Insulating end plate 2 adopts integral types, has avoided making owing to temperature is too high viscose glue to lose the shortcoming of the insulation property difference that cementability causes, and simultaneously, adopts integral type, makes simply, and is easy to process, reduced manufacturing cost.
