Description

可穩固葉輪及內轉子結合性之罐裝磁力泵Canned magnetic pump that can stabilize the combination of impeller and inner rotor

本新型是有關於一種罐裝磁力泵，特別是指一種可穩固葉輪及內轉子結合性之罐裝磁力泵。 This new model relates to a canned magnetic pump, in particular to a canned magnetic pump that can stabilize the combination of the impeller and the inner rotor.

現有一種磁力泵(台灣專利公告編號第507049號專利案)，在一葉輪的嵌合部外周，設有在周方向處朝徑方向突出的突起及溝，在相對應的一磁石環的嵌合部的內周也形成突起及溝。這些突起及溝的側面，也就是朝徑方向伸延的面，形成旋轉動力傳達面。一方面，在葉輪的嵌合部還設有一對孔，磁石環的對應部位也設有孔，當磁石環嵌合在葉輪時，該葉輪的突起嵌入於該磁石環的溝中，該磁石環的突起嵌入於該葉輪的溝中，利用多數銷穿設過磁石環的孔，以及葉輪孔，使得葉輪與磁石環達到接合目的。 There is a kind of magnetic pump (Taiwan Patent Publication No. 507049 patent case), in the outer periphery of the fitting part of an impeller, there are protrusions and grooves protruding in the radial direction in the circumferential direction, and in the fitting of a corresponding magnet ring. Protrusions and grooves are also formed on the inner periphery of the portion. The side surfaces of these protrusions and grooves, that is, surfaces extending in the radial direction, form rotational power transmission surfaces. On the one hand, a pair of holes are also provided in the fitting part of the impeller, and the corresponding parts of the magnet ring are also provided with holes. When the magnet ring is fitted into the impeller, the protrusion of the impeller is embedded in the groove of the magnet ring. The protrusion of the impeller is embedded in the groove of the impeller, and most pins are used to pass through the hole of the magnet ring and the hole of the impeller, so that the impeller and the magnet ring can achieve the purpose of joining.

雖然這種磁石環已可達到預期泵送液體的目的，但是，形成於該葉輪的突起側邊的該等突起面與磁石環對應的面都只是用於動力傳達，所以必須在葉輪與磁石環互相套接後還要利用銷穿設過磁石環的孔，以及葉輪的孔，才能使得葉輪與磁石環達到軸向的接合目的，如此一來，不僅結構較為複雜且製造組配較為麻煩。 Although this magnet ring can achieve the intended purpose of pumping liquid, the protruding surfaces formed on the protruding side of the impeller and the surfaces corresponding to the magnet ring are only used for power transmission, so the impeller and the magnet ring must be connected between the impeller and the magnet ring. After being sleeved with each other, a pin is required to pass through the hole of the magnet ring and the hole of the impeller, so that the impeller and the magnet ring can achieve the purpose of axial engagement. As a result, not only the structure is more complicated, but also the manufacturing and assembly are more troublesome.

當再如圖1所示，當罐裝磁力泵整體組裝完成後，該定位座20設置於該定子32外部，該基座10也設置於該定位座20外部。該泵前蓋60鎖固於該基座10其中一側，該後蓋70鎖固於該基座10另一側。當該馬達單元30的定子32通入電源時，能驅動該內轉子40產生轉動，且該內轉子40同步帶動該葉輪50轉動，則由該泵前蓋60前側引入的液體再被該葉輪50朝該泵前蓋60外部汲送，且達到泵送液體的目的。 As shown in FIG. 1 , after the canned magnetic pump is assembled as a whole, the positioning seat 20 is disposed outside the stator 32 , and the base 10 is also disposed outside the positioning seat 20 . The pump front cover 60 is locked on one side of the base 10 , and the rear cover 70 is locked on the other side of the base 10 . When the stator 32 of the motor unit 30 is powered on, it can drive the inner rotor 40 to rotate, and the inner rotor 40 drives the impeller 50 to rotate synchronously, and the liquid introduced from the front side of the pump front cover 60 is recirculated by the impeller 50 The pump is pumped toward the outside of the pump front cover 60, and the purpose of pumping the liquid is achieved.

且如圖1、圖3至圖7所示，當該內轉子40與該葉輪50進行組裝，且使該內轉子40與該葉輪50沿軸線L相對壓合，該前段41套入於該大徑部531時，該等凸肋413嵌入於該等嵌槽54，該外周面412與該大徑部531迫緊抵觸、該等第一斜面418與該等槽側面544迫緊抵觸，並利用該等切縫515的設置，使得該結合段51可被迫撐而向外變形並蘊藏回釋彈力，直到該等彈性卡勾516分別嵌扣於該等卡槽414中為止，該結合段51又利用原本被迫撐所蘊藏的回釋彈力所作用而向內偏動變形，且使該內轉子40與該葉輪50會稍微沿軸線L反向遠離，該等彈性卡勾516相對於該等卡槽414呈緊實扣住並產生止動效果，即可確保該內轉子40與該葉輪50能穩固接合，該葉輪50不會與該內轉子40脫離。 And as shown in FIG. 1, FIG. 3 to FIG. 7, when the inner rotor 40 and the impeller 50 are assembled, and the inner rotor 40 and the impeller 50 are relatively pressed together along the axis L, the front section 41 is sleeved in the large When the diameter portion 531 is formed, the protruding ribs 413 are embedded in the inserting grooves 54, the outer peripheral surface 412 is in tight contact with the large diameter portion 531, the first inclined surfaces 418 are in tight contact with the groove side surfaces 544, and the use of The arrangement of the slits 515 enables the coupling section 51 to be forced to deform outwardly and store elastic force to release the elastic force until the elastic hooks 516 are respectively engaged in the retaining slots 414 . The coupling section 51 The inner rotor 40 and the impeller 50 are slightly moved away from each other along the axis L, and the elastic hooks 516 are relatively opposite to the elastic hooks 516. The locking groove 414 is tightly fastened and has a stop effect, which can ensure that the inner rotor 40 and the impeller 50 can be firmly engaged, and the impeller 50 will not be disengaged from the inner rotor 40 .

因此，本新型利用該內轉子40的外周面412呈錐面狀，以及與該葉輪50的大徑部531呈錐孔狀，使得該外周面412與該大徑部531套合時可迫緊抵觸，也可確保同心對準，再配合該等該等凸肋413的該等第一斜面418與該等嵌槽54的該等槽側面544呈斜面狀並可迫緊抵觸，當該等彈性卡勾516相對於該等卡槽414產生扣合定位後，該內轉子40與該葉輪50各部位的接觸面之間可減少配合的餘隙，該葉輪50的運轉也較穩定。 Therefore, the present invention utilizes that the outer peripheral surface 412 of the inner rotor 40 is in the shape of a tapered surface and the large-diameter portion 531 of the impeller 50 is in the shape of a tapered hole, so that the outer peripheral surface 412 can be tightly fitted with the large-diameter portion 531 Concentricity can also be ensured, and the first inclined surfaces 418 of the protruding ribs 413 and the groove side surfaces 544 of the embedding grooves 54 are inclined and can be tightly collided. When the elastic After the hooks 516 are locked and positioned relative to the slots 414 , the clearance between the contact surfaces of the inner rotor 40 and the parts of the impeller 50 can be reduced, and the operation of the impeller 50 can be more stable.

綜上所述，本新型可穩固葉輪及內轉子結合性之罐裝磁力泵，整體結構簡單、製造組配容易，該內轉子40與該葉輪50組合後的穩固性佳，確實能達成本新型的目的。 To sum up, the novel canned magnetic pump that can stabilize the combination of the impeller and the inner rotor has a simple overall structure and is easy to manufacture and assemble. The inner rotor 40 and the impeller 50 are assembled The stability after closing is good, and it can indeed achieve the purpose of this new model.
