In a preferred embodiment: described magnetic driving equipment is divided into:
External magnet mounting groove, is located at the tail end of blade, it is equipped with external magnet; Described external magnet mounting groove embeds in described second inner chamber; Described internal magnet and external magnet is made to present mutually isolated nest relation.
In a preferred embodiment: described pump seat is also provided with the 3rd inner chamber, described 3rd inner chamber and the first inner chamber not connected.
In a preferred embodiment: described blade is rotationally connected by one end of sharf and described 3rd inner chamber; The two ends of described sharf are connected to bearing.
In a preferred embodiment: also comprise pump cover, described pump cover is connected with described pump seat by seal ring.
In a preferred embodiment: described pump cover is provided with accommodating inner chamber, described blade is accommodated in described accommodating inner chamber, and the described top of accommodating inner chamber and the other end of sharf are rotationally connected.
In a preferred embodiment: described internal magnet is mutually disjunct magnet piece; Described magnet piece becomes circle distribution to be installed on internal magnet mounting groove.
In a preferred embodiment: described external magnet is mutually disjunct magnet piece, and the magnet piece of described external magnet is with the magnet piece one_to_one corresponding of internal magnet and magnetic pole is contrary.
Compared to prior art, the technical solution of the utility model possesses following beneficial effect:
1. a kind of water pump adopting magneto drive of providing of the utility model, is rigidly connected traditional, has changed into and being flexible coupling.Complete seal isolation between motor and impeller, by means of only magneto drive.Therefore fundamentally stop the possibility of motor entering water, considerably increase the Security of water pump.
2. a kind of water pump adopting magneto drive of providing of the utility model, good seal performance, the long-time rear motor that uses still can keep good sealing, motor not easily occurs and to leak the situation of electric leakage.
3. a kind of water pump adopting magneto drive of providing of the utility model, does not contact between blade with motor and rubs, ensure that the working life of blade.
Accompanying drawing explanation
Fig. 1 is water pump structure explosive view during the utility model is preferably implemented;
Fig. 2 is the overall package figure of water pump during the utility model is preferably implemented;
The sectional structural map of water pump in Fig. 3 the utility model preferred embodiment.
Embodiment
Hereafter with embodiment, the utility model is described further by reference to the accompanying drawings.
With reference to figure 1-3, a kind of water pump adopting magneto drive, comprising:
Motor 1, its rotating shaft 11 is rotationally connected internal magnet mounting groove 12, and described internal magnet mounting groove 12 is equipped with internal magnet 13; Described internal magnet 13 is mutually disjunct magnet piece; Described magnet piece becomes circle distribution to be installed on internal magnet mounting groove 12.
Pump seat 2, it has the first inner chamber 21 and the second inner chamber 22 in nested setting and not connected; Described internal magnet mounting groove 12 embeds in described first inner chamber 21; Described pump seat 2 is also provided with the 3rd inner chamber 23, described 3rd inner chamber 23 and the first inner chamber 21 not connected.
Blade 3, the tail end of described blade 3 is provided with external magnet mounting groove 31, and described external magnet mounting groove 31 is equipped with external magnet 32; Described external magnet mounting groove 31 to embed in described second inner chamber 22; Described internal magnet 13 and external magnet 32 is made to present mutually isolated nest relation.Described external magnet 32 is mutually disjunct magnet piece, and the magnet piece of described external magnet 32 is with the magnet piece one_to_one corresponding of internal magnet 13 and magnetic pole is contrary.Described blade 3 is rotationally connected by one end of sharf 33 and described 3rd inner chamber 23; The two ends of described sharf 33 are connected to bearing 34.
