With reference to attached drawing, centrifugal pump component whole by reference label 10 table according to the present invention with electric motor Show.
Centrifugal pump component 10 includes wet zone and impeller, and wet zone has the intake line and conveyance conduit of known type (attached to be not shown in the figure), impeller is also not shown in the accompanying drawings, and impeller is known type, is immersed in wet zone.
Impeller is connected on the axis 17 of electric motor 19, and electric motor 19 is made of stator 12 and rotor 18.Electric motor It is arranged in stator case 11, stator case 11 is suitable for for electric motor being isolated with wet zone.
Centrifugal pump component 10 includes electrical box 13 at one end, and electrical box 13 includes to be suitable for controlling and driving electricity The electric plates 14 of dynamic motor 19.Electrical box 13 is with cylinder shape, and is closed at free end by lid 15.Favorably Ground, electric plates 13 also can have different extensions.
Particularly, electric motor 19 and electrical box 14 extend along same axis X, the rotation of the axis X and motor and impeller Axis is overlapped.Since there are intermediary element 16, electric motor 19 and electrical box 14 to be connected and be integrally formed.Intermediary element 16 is Connection and/or cladding element, and the shape with tubulose.
Electrical box 13 and stator case 11 have contact surface complimentary to one another.One or more first pins 28 are from electrical Box 13 extends and is adapted for inserting into the corresponding through-hole 29 in the contact surface that stator case 11 is arranged in.Pin 28 is suitable for connecting Box 13 and stator case 11 are connect, and is suitable for being conducive to the assembly of pump 10.
Equally, box 13 is provided with one or more second pins 30, and one or more second pins 30 are inside box 13 And it is upwardly extended in the side of lid 15, and the end of one or more second pins 30 is adapted for inserting into and is arranged in lid 15 The surface being internally pointed to towards box 13 on corresponding aperture in.Pin 30 is suitable for connecting box 13 and lid 15, and is suitable for having Conducive to the assembly of pump 10.
Electrical box 13 is internally provided with tubular body 34, and tubular body 34 has the extension axis being overlapped with axis X.Tubulose Main body 34 extends to the lid 15 of electrical box 13 from the surface contacted with stator case 11.At the part of tubular body 34, electricity Gas plate 14 and lid 15 are both provided with through-hole 36, and through-hole 36 has the extension axis being overlapped with axis X.
Advantageously, the extension axis in hole can not be overlapped with axis X, but can be parallel to axis X.
Through-hole 36 and tubular body 34 are suitable for the insertion of plug 35, and an end of plug 35 is contacted with wet zone.Pipe The hole 36 of shape main body 34 and lid 15 is dimensioned such that and shape, so as to ensure electric plates 14 and wet zone obstruction and every From (interference and isolation) (even if plug 35 is opened).
Particularly, plug 35 has profile 43 at one end, and profile 43 is suitable for entering the hole for being connected to wet zone, To serve as flow control component, and plug 35 has head 40 in another end, and head 40 is suitable for easily by making User is close.The length with cylinder shape and such of plug 35 so that in closed construction head 40 outer surface with At the level of the lid 15 of box 13 being on close level.Profile 43 include plate-like end member 47, end member 47 be connected to it is wet The Kong Zhongyu screwing element 42 in region continues together, and screwing element 42 is suitable for limiting plug 35 in a complementary fashion in threaded hole In fastening.The size phase with head 40 with the equal sized size with head 40 or in any case of discoid element 47 When size.
Head 40 is dish type, and has recess 44, is adapted for inserting into the end of screwdriver, to allow to unscrew and Tighten operation.
In a kind of constructive variations, plug 35 includes plug cladding element, invisible in figure, to hide plug Presence and generate more pleasant visual effect.
Plug 35 has middle section 41, which is also plate-like, and its size is similar to head 40 Size, to be conducive in plug insertion hole 36 and tubular body 34.
The first tubular portion 45 with the diameter smaller than 40 diameter of head is between head 40 and middle section 41.Tool Have the second tubular portion 46 of the diameter smaller than the diameter of the first tubular portion 45 between part 41 and end member 47 it Between.
The presence of these cylindrical parts with reduced diameter allows to avoid heat bridge, and allows to obtain under same cost Lighter plug.
Plug 35 is made of brass by turning (turning), and attached drawing (is used in all parts of plug 35 in Fig. 2 Label 40 to 47 indicates) it is obtained from single main body.
Advantageously, plug 35 can be made of stainless steel.
The O-ring 37 of known type ensures the sealing between wet zone and plug 35；The washer 38 of known type ensures wet Sealing between region, electrical box 13 and stator case 11.
Convex connecting plate 24 extends and adapt for being connected to the female terminal 25 of electric motor 19 in entrance from electric plates 14. In this way, plate 14 can provide electric power and control electric motor 19 for electric motor 19.
Electric plates 14 have connector 26 at one end, which is adapted for inserting into the power supply terminal outside pump In.In the insert region of terminal, box 13 has relative to the lug 27 outstanding of intermediary element 16.
It should be noted that the presence of plug according to the present invention allows to release by axis in a manual manner for user Foliation wheel.
Additionally, it should be noted that the size and shape of plug allow user to be easier access to plug.
It should also be noted that having between head, central disk-shaped element and end discoid element subtracts relative to them The presence of the plug of the cylindrical cross-section of small diameter allows to avoid triggering heat bridge, and defines plug, for same cost, The plug has lesser weight.
In practice it was found that the present invention realizes expected purpose and target, provide a kind of with electric motor Centrifugal pump component, electric motor is arranged in stator case, in stator case, comprising electric plates and at free end The axial end portion of stator case is arranged in by the box of closed with covers, which includes wet zone, which is characterized in that pump assembly Including plug, which has at one end is suitable for entering the profile being connected in the hole of wet zone, which is used as Flow control component, and the plug has head at the other end, and which is suitable for providing easy access to user, this is inserted Plug has such length, so that the outer surface on head is at the level of the lid with box being on close level in closed construction.
Thus the present invention conceived allows many modifications and variations, and all such modifications and variations are all in appended claims In the range of；In addition all details can be by other technically equivalent element substitutions.
In practice, used material (as long as they are compatible with specific purposes) and possible shape and size, It can be arbitrary according to demand with the prior art.
