Description

Centrifugal pump with spiral case
Technical field
The present invention relates to a kind of centrifugal pump with spiral case.The invention still further relates to the application of this centrifugal pump.
Background technique
Centrifugal pump with spiral case is well-known.Described a kind of distinguish spiral case that is used for centrifugal pump in DE 103 47 302 A1, this spiral case has carried out optimized design by fluidics.Such centrifugal pump is motorized motions normally, and wherein the stator arrangement of motor is being done in the chamber, and rotor arrangements is in wet chamber.Therefore rotor rotates in wet chamber, and washing-round is carried out by the flowing medium that will carry in this wet chamber.Do chamber and wet chamber and separate, wherein disadvantageously must between one of them part of spiral case and chink type pipe, arrange seal element, do in the chamber to avoid liquid or steam to enter into from wet chamber by the chink type pipe of independent layout.Under working time longer situation, promptly become gradually under the cavernous situation at seal arrangement, perhaps act under the situation of the vibration on the centrifugal pump in existence, often can not stop liquid or steam to enter into and do in the chamber from wet chamber.This for example causes the damage of electronic component, and except stator, these electronic components equally also are arranged in to be done in the chamber.
Summary of the invention
Thereby the objective of the invention is to propose a kind of centrifugal pump with spiral case, in this centrifugal pump, avoided liquid or steam to enter into fully and done in the chamber from wet chamber around rotor.
Purpose of the present invention realizes by a kind of centrifugal pump with spiral case, this spiral case comprises first housing parts and second housing parts, wherein second housing parts is designed to continuous cup-shaped in zone line, be used to hold the rotor that is positioned in the wet chamber N, and design is useful on the rotatably bearing of support rotor in cup like bottom, wherein around second housing parts, be equipped with stator at dried chamber T lining at the region exterior of rotor.Second housing parts is designed to continuous cup-shaped in zone line, this means: the parts that the near cylindrical of a bottom with sealing is arranged around longitudinal axis design.Design limiting by the cup-shaped chamber N that goes out to wet, this wet chamber is designed for and holds rotor.Second housing parts designs in cup like bottom and is useful on the rotatably bearing of support rotor, and wherein cup like bottom or itself be used as bearing perhaps only is used to hold the bearing that is used for rotor.
Demonstrated astoundingly already: the design proposal of the continuous cup-shaped by second housing parts, can avoid liquid to enter into fully and do in the T of chamber from wet chamber N.This does not just advantageously need by seal element wet chamber N and dried chamber T to be separated by independent chink type pipe.Even therefore guaranteed also that under the situation of longer working time dried chamber T and wet chamber N separate all the time.Thereby advantageously do not need to arrange independent chink type pipe fully.
A preferred design proposal according to the present invention is designed to: second housing parts externally has the border of camber in longitudinal profile in the zone, and this border is perpendicular to the flow direction that flows through the medium that comes from inlet E.At this, concrete arching trajectory is realized optimization by fluidics by engineering design.Therefore can be implemented advantageously in the best adjustment of the liquidity ratio in the spiral case, thereby can advantageously reduce structure space essential for centrifugal pump.
Theme of the present invention in addition comprises that also centrifugal pump is as the application of cooling water centrifugal pump in Motor Vehicle.Cooling water centrifugal pump in the Motor Vehicle must be worked on long period fault-free ground, must prevent that wherein electronic component from sustaining damage in dried chamber T.Therefore centrifugal pump is particularly advantageous as the application of cooling water centrifugal pump in Motor Vehicle.
Description of drawings
Below (Fig. 1 to Fig. 3) in detail and exemplarily the present invention is illustrated with reference to the accompanying drawings.
Fig. 1 shows the longitudinal profile of centrifugal pump;
Fig. 2 shows the longitudinal profile of centrifugal pump with the form of exploded view;
Fig. 3 shows the longitudinal profile according to the centrifugal pump of prior art.
Embodiment
Figure 1 illustrates the longitudinal profile of centrifugal pump.This centrifugal pump has spiral case, and this spiral case comprises first housing parts 1 and second housing parts 2, and wherein second housing parts 2 is designed to continuous cup-shaped in zone line, is used to hold the rotor 3 that is positioned in the wet chamber N.Second housing parts 2 has in cup like bottom 2 ' and is used for the rotatably bearing 3 ' of support rotor 3.Around second housing parts 2, be equipped with stator 4 at dried chamber T lining at the region exterior of rotor 3.Doing chamber T externally closes with respect to surrounding environment by housing 5.Second housing parts 2 externally has the border 2 of camber in longitudinal profile in the zone *, this border is perpendicular to the flow direction that flows through the medium that comes from inlet E.Flowing through the medium that comes represents with a thick arrow.By arc border 2 *Make the liquidity ratio of spiral case inside realize optimization.Do not avoided liquid or steam to enter into yet and done chamber T even do not arrange seal element, thereby protected electronic component (not shown) and stator 4 in the dried chamber, prevented that it from sustaining damage owing to liquid or steam from wet chamber N.
In Fig. 2, show the longitudinal profile of centrifugal pump with the form of exploded view.Second housing parts 2 is designed to continuous cup-shaped in zone line, be used to hold rotor 3.Therefore, keep apart with dried chamber T (not shown) fully by the wet chamber N (not shown) that this zone line limited, stator 4 is located in this dried chamber T.
Figure 3 illustrates longitudinal profile according to the centrifugal pump of prior art.Centrifugal pump according to prior art has spiral case, and this spiral case comprises the first housing parts 1b and the second housing parts 2b.The liquid fed sheet of a media (representing with thick arrow) for the treatment of enters wet chamber Nb through inlet Eb, and rotor 3b rotatably is placed in the wet chamber.At the region exterior of rotor 3b, the Tb lining is equipped with stator 4b in dried chamber.At this, do chamber Tb and close with respect to surrounding environment by housing 5b.According to prior art, wet chamber Nb and dried chamber Tb separate by arranging chink type pipe 6b, wherein do chamber Tb because the unfavorable layout of seal ring 7b equally also may make liquid enter into from wet chamber Nb, the sealing ring can be arranged between the chink type pipe 6b and the second housing parts 2b.If for example oscillating action is on centrifugal pump, so just may make liquid or steam cross seal ring 7b and enter into dried chamber Tb from wet chamber Nb, this illustrates by thin arrow.Like this, stator 4b or the other electron component (not shown) that equally also is positioned in the dried chamber Tb just may sustain damage, and this is avoided by centrifugal pump according to the present invention.
