Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and embodiments.
Refering to fig. 1 to Fig. 3, one embodiment of the canned magnetic drive pump of the utility model includes one positioning unit 10, one
20, pump front covers 30 of motor unit and a dissipating cover 40.
The positioning unit 10 include one in hollow ring frame-shaped positioning seat 11, be integrally formed and be connected to the positioning seat 11
A pedestal 12 and an interlocking in the positioning seat 11 and be in hollow form ring frame piece 13.The positioning seat 11 surrounds one
Axis L and an inner hole 14 can be defined, which has an outer ring surface 111, and the outer ring surface 111 is perpendicular to the axis
The chamfered shape of L is in polygon, and in the present embodiment, which is in octagon perpendicular to the chamfered shape of axis L.
The motor unit 20 includes that a shell being installed in the inner hole 14 of the positioning unit 10 21, one is sheathed on this
22, rotors 23 being installed on inside the shell 21 of stator between shell 21 and the positioning seat 11 are installed on the shell
21 and shaft 25 and one for supporting the rotor 23 be connected to the impeller 24 of the rotor 23.The shell 21 has one
It is installed for the rotor 23 and the shaft 25 and is connected to the main barrel portion 211 and vertical in the main barrel portion 211 of hollow tube-shape and one
In the flange 212 of axis L setting, which defines one along axis L setting with the flange 212 jointly and is in
Unidirectionally open accommodating space 213.
The pump front cover 30 is installed on 11 side of positioning seat along axis L, and covers at outside the impeller 24, the flange
212 clippings are between the ring frame piece 13 and the pump front cover 30.
The dissipating cover 40 is installed on 11 other side of positioning seat along axis L, and has one and be resisted against the positioning seat 11
Transverse plane 41, one along axis L in contrast to the lateral surface 42 of the transverse plane 41 and it is several be convexly equipped in the lateral surface 42 dissipate
Hot fin 43.The radiating fin 43 collectively forms the outer ring edge 431 that a chamfered shape is in polygon, which becomes
It is bordering on the outer ring surface 111, the chamfered shape of the outer ring edge 431 is similar to the outer ring surface 111 perpendicular to the section shape of axis L
Shape, total heat dissipation area which is constituted are greater than the area that the outer ring surface 111 is constituted perpendicular to the section of axis L.
It is pre- for further understandings of effect, application technology means caused by each component cooperation of the utility model, and institute
It will be described as follows again the effect of phase reaches, it is believed that when can have deeper into and specific understand to the utility model therefrom.
As shown in Figures 1 and 3, when the canned magnetic force pump installation overall package of the utility model is completed, the positioning seat is utilized
11 can position for 20 integral installation of motor unit, and the pump front cover 30 is locked in the positioning seat 11 and 13 side of ring frame piece,
The dissipating cover 40 is locked in 11 other side of positioning seat, and integrally combination is quite firm for the canned magnetic force pump installation.
And when the stator 22 is passed through power supply, the rotor 23 can be driven to generate rotation, and the rotor relative to the shaft 25
The rotation of the 23 synchronous drives impeller 24, then the liquid introduced by the pump front cover 30 can be drawn by the impeller 24 to be sent again towards the pump front cover 30
Outside discharge, and achieve the purpose that pump liquid.
Again as shown in Figure 1, Figure 2 and shown in Fig. 4, using the outer ring surface 111 of the positioning seat 11 perpendicular to the chamfered shape of axis L
In octagonal effect, then under the conditions of having the same diameter with existing cylindrical bracket, which, which has, is produced
Raw biggish heat dissipation area, can generate preferable heat dissipation effect, not need that radiating fin, the positioning list is arranged in the positioning seat 11
The manufacture of member 10 is relatively easy to, and cost is relatively low.In addition, cooperating the setting of the radiating fin 43 of the dissipating cover 40, then can increase
Add the integral heat sink effect of the canned magnetic drive pump.
It is noted that as shown in figure 4, the radiating fin 43 of the dissipating cover 40 collectively forms chamfered shape in more
The outer ring edge 431 of side shape, the chamfered shape of the outer ring edge 431 are similar to the outer ring surface 111 perpendicular to the section shape of axis L
Shape then also can increase the area that the dissipating cover 40 lays radiating fin 43, the excellent in heat dissipation effect of the dissipating cover 40.And the outer ring edge
The 431 total heat dissipation areas constituted are greater than the area that the outer ring surface 111 is constituted perpendicular to the section of axis L, the dissipating cover 40
Excellent in heat dissipation effect.
In conclusion the canned magnetic drive pump of the utility model, overall structure is simple, can generate preferable heat dissipation effect and can reach
