Abstract

A pump for ponds, aquariums or similar facilities has a synchronous motor arranged within a motor housing. The motor has a permanent-magnet rotor and a stator, wherein the rotor is separated from the stator by an inner wall of the motor housing. A housing part is provided that forms a flow channel. The pump has a removable mounting flange for rotatably securing the rotor. The housing part is detachably mounted on the flange by a fastening device. The mounting flange seals a can forming the inner wall relative to the remaining motor housing and secures a bearing bracket serving for supporting the rotor.

Description

The pump that is used for pond, fishpond or similar facilities
Technical field
The present invention relates to a pump that is used for pond, fishpond or similar facilities, it has a synchronous machine in electric machine casing, and it has rotor and a stator of a permanent magnetism, and its rotor separates with stator by an inwall.This housing has a housing parts that constitutes a flow channel at least in addition.
Background technique
Such pump is for example open by DE19509454.Shortcoming in this pump is in order to safeguard pump, housing must be opened in large area, so some zones that may not need to clean also to be exposed.
Summary of the invention
Therefore the objective of the invention is, ground easy to maintenance and all the other are generally improved design pump of the same type.
This purpose reaches by a pump according to the preamble of claim 1, it is characterized in that: it has the mounting flange of dismountable, a rotatable fixed rotor, and the housing parts that constitutes a flow channel removably is installed thereon.By the mounting flange that the present invention constitutes, can tear next housing parts open, therefore the pump impeller of settling on rotor can be accepted cleaning, and needn't open other member of electric machine casing.In addition, can realize different but housing parts fixed in position that can identical installation on pump by fixing device.This pump can be applied to different application targets in this mode.
As optimal way, a printed wiring board that is used for driving-controlling device extends in the back of staor winding at electric machine casing.It is different that printed wiring board occupies the position by stator decision (wegweisende) in this and the prior art, and this electric machine casing is because less status requirement the occurring and just can be used for diversified housing form of building blocks of function thereupon.This has also improved the application area of pump of the present invention in addition.
Description of drawings
Additional advantages of the present invention and details can obtain from the schematic representation of the dependent claims described subsequently and theme of the present invention.Shown in the drawings:
Fig. 1 is the exploded view of theme of the present invention,
Fig. 2 is the side view of the parts shown in the decomposition shown in Figure 1,
Fig. 3 is the cross-sectional view by subject component of the present invention.
Embodiment
Fig. 1 illustrates a kind of pond, fish pond-or pump of the present invention of similar facilities that is used for.In the inside, part area of electric machine casing 1 synchronous machine is set, it has a magneto rotor 2, its operation in this not shown stator 3 again.Rotor has a pump impeller 4 and a bearing cap 5 distolateral, and this bearing cap is applied to cover a housing opening 6.By this housing opening 6, rotor 2 can be installed in synchronous machine between the pole shoe of electric machine casing 1 inside.
According to the present invention a mounting flange 7 is set, its bearing cap 5 that will be used for supporting rotor 2 securely is expressed to a contact area 8, so rotor 2 is bearing in the pump impeller side.Just the bearing position of rotor 2 from it can be taken out by pulling down this mounting flange 7.
Mounting flange 7 is deviating from the fixing device 9 that has a locking mechanism form on the side of bearing cap 5.This locking mechanism can realize that housing parts 11 is fixing reliably.The high discharge capacity that fixedly being particularly suitable for of this form can be realized by the synchronous machine of pump of the present invention.Simultaneously, this housing parts 11 can also be with simple mode and method dismounting.
Advantageously verified, for stationary housing part 11 reliably, be provided with at least two, the better still mounting flange 7 in four draw-in groove zones 12, fixed particularly well by this housing parts 11 of draw-in groove zone.This draw-in groove zone 12 jointly constitutes this fixing device 9 with the card arm 14 of housing parts 11.
The installation of this housing parts 11 be imported into realization and therefore be simple equally.Bolt 13 is used for mounting flange 7 is fixed on reliably the part that comprises motor of electric machine casing 1 simultaneously.
In addition, housing parts 11 has two zones, and they are to be used to continue to carry or the flow channel 15 and 16 of pump up water.For the water that is pumped continues to carry well, discharge herein-or on the pressure side passage 16 be set to shaft axis guiding outward radially from rotor.Simultaneously water input channel 15 is that shaft axis with rotor extends coaxially.The join domain 18 not only input but also passage 16 or 15 discharge water all has thread forms can be installed other pipeline by it.Therefore pump of the present invention can assemble more complicated system.It for example can be used as transfer pump and is applied to a water filter or musical fountation and on the water or under water.
Mounting flange 7 is being expressed on the bearing cap 5 under the situation, rotor 2 is bearing in the electric machine casing 1 reliably by a bearing 19 that applies effect by bearing cap 5.Similarly, towards a gas tube of fixedlying connected with electric machine casing 1 (Spaltrohr) 21 extruding, its inner region with electrified building blocks of function that can prevent electric machine casing 1 is by water intrusion on the running position of pump for bearing cap 5.Therefore gas tube 21 is the inwall of electric machine casing, and it separates rotor 2 and stator 3.As preferably, gas tube 21 has a bearing 20 that is used for rotor equally on it deviates from the end of pump impeller 4.
In order additionally to seal this inner space to prevent the intrusion of water, these building blocks of functions that apply electric current comprise that the printed circuit board for the driving-controlling device setting is all surrounded by mould material, and it similarly is connected gas tube 21 with electric machine casing 1.In addition, seal arrangement 22 is with respect to the motor regional seal gas tube of being poured into a mould 21, and therefore, mould material can not invade in the zone that should not be poured into a mould under installation situation.
A connection piece 23 is used to make electric machine casing 1 to be installed in different positions, and it can be applied to the pad pin that need not describe again (Stellfu β) especially.The fixed element that also can replace even so being provided for the link 23 of pad pin is installed and other appearance is set on electric machine casing 1 makes pump can be applied to the formal of hope by it.
In addition, also have within the scope of the invention, these since external stylings of housing produce but the unnecessary shell area that is not used in building blocks of function separate mutually with all the other shell area of being furnished with the building blocks of function of pump by a partition wall 24.Therefore, except improved impression visually, also realized the consumption that reduces of essential mould material.
In addition, be in the zone of circulation water, an antifreeze safety installations to be set to what pump of the present invention brought advantage.This has in electric machine casing inside makes pump avoid damaging under the icing regimen condition.Housing parts 11 has at least one by (geschlossenporigen) of closed porous but flexible foam-filled side chamber 25 for this reason, and it directly is passed in the zone of guiding water.The water that freezes just may be expanded in this side chamber 25, thereby can not cause the damage in electric machine casing 1 inside.
