Abstract
The utility model discloses a motor for a submersible pump with a sealed stator winding. The utility model is formed by that on the basis of original motor structure which is composed of a machine base, a stator winding, a rotor, a bearing, an end cover, screws and a top thread, the excircle of a sealing sleeve is in interference fit with a stator core; both ends of the inner circle of the sealing sleeve are in interference fit with the excircle of a bearing chamber of the end cover; sealing rings are connected by the screws of the end cover and the machine base; the stator winding is sealed in the sealing rings by the sealing sleeve and the sealing rings. Under the condition that the performance of the motor is not affected, the stator winding is sealed, avoiding that the short circuit of a motor winding caused by that water enters into a mould cavity of the motor.
Description
The utility model relates to a kind of sealed stator winding type diving electric motor for pump, belongs to electronic product.
Waterproof and dampproof many employing mechanical seals of existing all kinds of diving electric motor for pump, because the seal that adds is a rotating part, fragile water inlet can't normally move during work, simultaneously, and the manufacturing process complexity, the cost height, result of use is undesirable.
The utility model provides a kind of and easily intakes at existing pump motor at the problems referred to above, causes the stator winding short circuit and the sealed stator winding type invented diving electric motor for pump.
Task of the present utility model is finished as follows: on the original electric machine structure basis that is made of support, stator winding, rotor, bearing, end cap, screw, jackscrew, circle two ends and the outdoor round interference fit of end cap bearing in sealing shroud cylindrical and the stator core interference fit, sealing shroud; Sealing ring is sealed in stator winding in the formed sealing ring by above-mentioned sealing shroud, sealing ring by the screw attachment of end cap, support.
The utility model adopts by support, stator winding, rotor, bearing, end cap, screw, jackscrew, sealing shroud, the sealing ring that sealing ring forms, at stator, under the rotor airgap permanence condition, stator winding is sealed in the sealing ring, sealing shroud has been isolated water or the moisture that enters stator winding in the motor die cavity, sealing ring has sealed water or the moisture that enters stator winding from support and end cap cooperation place, like this, under the condition that does not influence motor performance, sealed stator winding, avoided the motor windings short circuit that causes because of motor die cavity water inlet, this structure also is suitable for the waterproof and dampproof of common electric machine.
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Fig. 1 is the utility model overall structure figure
With reference to accompanying drawing 1, on the original electric machine structure basis that constitutes by support 1, stator winding 2, rotor 3, bearing 4, end cap 5, screw 6, jackscrew 7, circle two ends and end cap 5 bearing chamber cylindrical interference fit in sealing shroud 8 cylindricals and the stator core interference fit, sealing shroud; Sealing ring 9 connects by the screw 6 of end cap 5, support 1, by above-mentioned sealing shroud, sealing ring stator winding is sealed in the formed sealing ring.
Claims (1)
1, a kind of sealed stator winding type diving electric motor for pump, it is made of support 1, stator winding 2, rotor 3, bearing 4, end cap 5, screw 6, jackscrew 7, it is characterized in that: on the original electric machine structure basis that constitutes by support 1, stator winding 2, rotor 3, bearing 4, end cap 5, screw 6, jackscrew 7, circle two ends and the short 5 bearing chamber cylindrical interference fit of covering in sealing shroud 8 cylindricals and the stator core interference fit, sealing shroud; Sealing ring 9 connects by the screw 6 of end cap 5, support 1, by above-mentioned sealing shroud, sealing ring stator winding is sealed in the formed sealing ring.
