Abstract
The utility model is a screen motor of screen pump for well use. The motor includes a rotor component (2), a stator component (6), a casing (5), an upper and a lower end covers (1, 10), and is characterized in that an inner screen barrel (7) made of stainless steel arranged between the stator component (6) and the rotor component (2) and. The inner screen barrel (7) is adhered tightly to the inner surface of the stator component (6) and has spiral concavo-convex waves (4) on end sections, and the diameters (H) at two ends are slightly larger than that (h) at the middle part. By adhering the inner screen barrel onto inner surface of the stator component tightly, the utility model has the advantages of reduced gap between the stator and the rotor, reduced loss, improved power factor, and improved energy saving effect.
Description
Technical field
The utility model relates to immersible pump, the particularly well improvement of the shield electric machine of canned pump.
Background technology
The present well shield electric machine of canned pump, comprise rotor assembly, stator module, casing, end cap up and down, be provided with the shielding inner sleeve that nonmagnetic substance is made between rotor assembly and the stator module, make airtight isolation between rotor assembly and the stator module, can enter cooling water in the shielding inner sleeve, to strengthen the cooling effect of motor.During by prior art assembling stator module and shielding inner sleeve, inevitable meeting between gap, add inner sleeve thickness, the air gap that is equivalent between rotor and the stator increases, and air gap can produce eddy current loss in rotating magnetic field, the air gap increase directly causes empty load of motor electric current, loss to increase, and the power of motor factor reduces.As existing certain series products, its loss is 412W, and power factor (PF) is 0.93, and energy utilization rate is relatively low.
Summary of the invention
The utility model purpose is to provide the shield electric machine of a kind of high efficiency well with canned pump.
The utility model well is with the shield electric machine of canned pump, comprises rotor assembly, stator module, casing, end cap up and down, it is characterized in that being provided with between rotor assembly and the stator module stainless steel shielding inner sleeve, and this inner sleeve is closely connected in the inner surface of stator module.
One section of above-mentioned shielding inner sleeve two-port is shaped on the spiral embossing ripple, and the slightly larger in diameter of two-port is in the diameter at middle part.
The utility model has the advantages that: compared with prior art, because inner sleeve is closely connected in the inner surface of stator module, the air gap that is equivalent between rotor and the stator reduces, and loss reduces, and power factor (PF) improves.According to test, to compare with above-mentioned existing similar same specification product, loss reduces 3-5W, and power factor (PF) can improve 5 percentage points, and energy-saving effect is remarkable.
Description of drawings
Fig. 1 is and the utility model structural representation.
Fig. 2 is a K place partial enlarged drawing among Fig. 1.
Mark among the figure: 1, upper end cover, 2, rotor assembly, 3, insulating paper, 4, ripple, 5, casing, 6, stator module, 7, the shielding inner sleeve, 8, epoxy resin, 9, filler, 10, bottom end cover.
Embodiment
As shown in the figure, casing 5 and stainless steel at shield electric machine shield the stator module 6 of packing between the inner sleeve 7, one section of shielding inner sleeve 7 two-port is shaped on spiral embossing ripple 4 in advance, diameter h in the middle part of the diameter H of two-port is slightly larger than is with the circulation that helps cooling water, the friction that reduces balance weight and the increase fastening force to stator module 6 two ends winding wire insulant epoxy resin 8 and filler 9.Adopt expansion process at last, stainless steel shielding inner sleeve 7 is expanded make it closely connected inner surface, reduce the gap between rotor assembly 2 (not drawing complete among the figure) and the stator module 6 in stator module 6.
Claims (2)
1, a kind of well shield electric machine of canned pump, comprise rotor assembly (2), stator module (6), casing (5), end cap (1,10) up and down, it is characterized in that being provided with between rotor assembly (2) and the stator module (6) stainless steel shielding inner sleeve (7), this inner sleeve is closely connected in the inner surface of stator module (6).
2, the well as claimed in claim 1 shield electric machine of canned pump, its feature is shaped on spiral embossing ripple (4) at one section that shields inner sleeve (7) two-port, and the diameter of two-port (H) is slightly larger than the diameter (h) at middle part.
