Description
Technical field
The utility model relates to a kind of Water-pumping motor with insulation function, particularly relates to a kind of Water-pumping motor with insulation function be applied on pond.
Background technology
Motor applications, on pond (particularly Inflation water pond or pipe support pond), realizes water circulation for drawing water.In order to ensure the fail safe in pond, require very high to the insulation property of motor.Existing technology normally adopts the structure of mechanical seal to carry out exhausted water-stop to the output shaft of motor, avoids water to penetrate into motor internal along the output shaft of motor and causes leaky.But structure length service time one of mechanical seal is easily aging on the one hand there is hidden danger such as leaking; On the other hand, if the manufacturing defect that motor itself exists causes electric leakage, electric current will directly be transmitted in the middle of pond by output shaft, causes electric shock accidents.Therefore, still there is the defect of insulation property difference in existing motor.
Utility model content
The utility model provides a kind of Water-pumping motor with insulation function, which overcomes the deficiency existing for background technology.The utility model solves the technical scheme that its technical problem adopts:
A kind of Water-pumping motor with insulation function, comprise output revolving shaft and impeller, also comprise and to be connected between this output revolving shaft and this impeller and insulating sleeve for output revolving shaft and impeller are separated, this insulating sleeve encases the leading section of this output revolving shaft, this impeller is connected on this insulating sleeve, described impeller, insulating sleeve, output revolving shaft three synchronous axial system.
Among one preferred embodiment: also comprise the Metallic rod be embedded at this impeller internal, described Metallic rod, output revolving shaft, insulating sleeve three are positioned on same axis.
Among one preferred embodiment: described impeller is working of plastics, impeller encases this Metallic rod when injection mo(u)lding.
Among one preferred embodiment: this insulating sleeve adopts the mode of injection mo(u)lding to encase this output revolving shaft.
Among one preferred embodiment: the outer surface of this output revolving shaft is provided with double wedge, this insulating sleeve encases double wedge; It is non-circular linkage section that this output revolving shaft is provided with cross section, and this insulating sleeve encases linkage section.
Among one preferred embodiment: the outer surface of described insulating sleeve is provided with screw thread, the middle part of this impeller is provided with mandrel portion, and described insulating sleeve is inserted in this mandrel portion and is threaded togather with mandrel portion.
Among one preferred embodiment: described output revolving shaft is working of plastics, described output revolving shaft and insulating sleeve integrated injection molding.
The technical program is compared with background technology, and its tool has the following advantages:
1, this insulating sleeve is connected between this output revolving shaft and this impeller, once the electric leakage of motor therein, insulating sleeve can stop current delivery to arrive in the middle of impeller and water, thus has effectively blocked the possibility that electric current contacts with the water in pond, improves the security performance in pond.
2, Metallic rod is embedded at this impeller internal, effectively can improve the strength and stiffness of impeller, and the power of motor is got a promotion.
3, this insulating sleeve adopts the mode of injection mo(u)lding to encase this output revolving shaft, and the two is connected firmly.Particularly when the outer surface of this output revolving shaft is provided with double wedge, the possibility that insulating sleeve is deviate from vertically can be effectively reduced.
4, described output revolving shaft is working of plastics, and described output revolving shaft and insulating sleeve integrated injection molding, structure is simpler.
