Filter insert in inhalation area.
Suction passage for sucking the desired fluid for this pump insert is generally cut in gear mechanism housing
Manufacture with cutting processing.However, the manufacture of machining is that relative cost is high.Therefore following solution is found, wherein can be real
The fluid stream of manufacture with the optimization in suction passage simultaneously of existing low cost is oriented to.
The content of the invention
The object of the present invention is to propose a kind of pumping unit, wherein suction passage can manufacture at low cost, and wherein can be real
The fluid stream now optimized is oriented to.
The solution of the purpose realizes that the pumping unit includes the pump with the housing of itself by a kind of pumping unit
Insert, wherein pump insert are fitted into receiving member, wherein the suction passage for pump insert is formed in receiving member, to inhale
Enter fluid, wherein being provided with the insert for being used for optimizing fluid guiding in suction passage.
According to the present invention, pump insert is interpreted as following equipment, and the equipment mainly includes the component of pump, but is configured to
For being encased in receiving member, such as housing, wherein receiving member is provided with for drawing fluid into by pump insert and receiving
Suction passage in the chamber that part is formed.This pump insert is also referred to as used as cartridge-type pump or boxlike pump.Pump insert, receiving member and embedding
Entering part can be provided by different manufacturers, and wherein pump insert and insert are in an advantageous manner at the manufacturer of receiving member
Installation.
By insert, suction passage can be provided simply and at low cost in receiving member, the suction passage
Geometry need not be formed in a manner of flow optimized, but thus fluid can not ideally flow in the case of no insert
It is dynamic, and such as easily foaming, this can negatively affect the service life of this pumping unit.
The improvement project of the present invention provides in dependent claims, specification and accompanying drawing.
In one preferred embodiment, receiving member forms reservoir for holding a fluid.
Here, receiving member is preferably able to be gear mechanism housing.The inner chamber of gear mechanism housing is formed for fluid, such as
Container for oil.Pump insert is fitted into gear mechanism housing wall, wherein being formed in gear mechanism housing wall for that will flow
The suction passage that body sucks from container.
In one preferred embodiment, suction passage with no chips manufactures.
Suction passage is for example cast together during receiving member is poured into a mould.Since when core or sliding block shape, passage geometry
Structure is main influence, so suction passage can not formed optimally for the suction of fluid.
According to the present invention, by suction passage without the geometry of optimization and due to the fluid to foam at high speed
Cavitation this actual conditions in pumping unit are can result in, insert is loaded in suction passage according to the present invention.
This, preferably in the region of the inlet hole of pump insert, increases to the particularly preferred machining of suction passage, thus in the area
Insert can be simply encased into domain.
Manufacture to the preferred machining in region, because the geometry of receiving member, such as the wall thickness of receiving member,
The demoulding of casting mold is not allowed in the region.When the wall thickness of receiving member is sufficiently thick, during to realize the demoulding of casting mold,
The region can also be formed by pouring into a mould.
In one embodiment according to the present invention, insert is by plastic manufacturing.
Insert preferably manufactures at this in injection moulding.
Injection moulding allows the inexpensive manufacture of complicated geometry.
In one preferred embodiment, pumping unit and then pump insert is configured to vane pump.
Vane pump and then pump insert mainly includes rotor and contour loop, the rotor is arranged on one or more
Blade in the gap of rotor, wherein rotor are anti-lost, such as by means of collar, and torsionally it is arranged on drive shaft
On.The first pressing plate and the second pressing plate are provided with the driving shaft, and wherein rotor, at least one blade and contour loop is arranged on pressing plate
Between.
Alternative can for example be configured to gear pump in vane pump, pump insert.
In the blind hole of pump insert insertion receiving member.It is fixed on receiving member in order to which pump insert is maintained in position
There is lid, its middle cover is pressed against the wall portion of receiving member and is maintained in position.
Pump insert has at least two seals being spaced apart from each other, and wherein seal is preferably configured as O-ring.One
In individual preferred embodiment, provided with the seal on the first pressing plate and the second seal on the second pressing plate, wherein
Seal on first pressing plate seals suction chamber relative to pressure chamber and the seal of the second pressing plate seals relative to lid, with
Just prevent leakage.
Brief description of the drawings
Below, the present invention is illustratively described by referring to accompanying drawing.
Fig. 1 shows the profile of pumping unit as be known in the art；
Fig. 2 shows the profile of the pumping unit according to the present invention.
Embodiment
Figure 1 illustrates pumping unit 1 As be well known in the art.For clarity, pump insert is not shown in itself, and
And the pump insert is set to be used to be arranged in section A.In the housing for receiving, such as in transmission device, appearance is mounted with
Receive part 2, the suction passage 3 for trandfer fluid is provided with the receiving member, is wherein formed to the machining of suction passage 3.
The composition scheme of the machining of suction passage 3 and then spick-and-span inner face I designing and processing can realize that pump is inserted
Enter the optimization of the fluid stream in the pump chamber of part, thus reduce or prevent the suction of air.Injector is provided with suction passage 3
5。
Fig. 2 shows the pumping unit 1 according to the present invention in the housing formed by component, and the housing provides receiving member 2,
Wherein pumping unit is also shown in a manner of no pump insert.Suction passage 3 is cast together in receiving member 2.This housing
The pouring technology explicit costs of part is lower, but inner face I is substantially more more coarse than the manufacture by means of cutting method.If it is assumed that it is
Gear mechanism housing, significantly, oil conservator have constructed together as container B in cast.
Fluid stream can turbulently reach pump without the help of other measures.
In order to optimize fluid stream and controllably design becoming a mandarin for pump, insert 4, institute are loaded in suction passage 3
Stating insert improves fluid stream.
Insert has the shape of stem bar, and the stem bar from the internal diameter I corresponding to suction passage outer diameter A D extend to appearance
Receive portion A diameter D.Part in suction passage 3 is cylinder and until depth T is extended in suction passage 3.It is described
Embodiment is exemplary.Insert can also have the shape of cylinder, and the cylinder terminates in section A to ground connection
In, or the insert have with arbitrary form extend cylinder form, wherein for extend without necessarily achieving diameter D.
In a preferable implementation flexible program, by the way that provided with midfeather, the fluid stream in insert 4 can be divided into
At least two become a mandarin.
It is made up of plastics according to the insert 4 of the present invention, and is preferably manufactured in injection moulding.Therefore, there are multiple knots
The more complicated insert of the suction passage section of structure is also feasible.
In another preferred embodiment, the seal that can be provided around between insert 4 and suction passage 3
(not shown), for example, at least an O-ring or the sealing lip being injected on insert 4.
When needed, the (not shown) of injector 5 is equally inserted in suction passage 3.
By the way that insert to be pressed into the part opened wide towards section A of suction passage, the loading of insert is carried out.Optimal
In the case of, the structure being cast of suction passage, which is securely enough to guided and fixed, loads part.But if necessary, suction passage
Also must also be reworked, so that for example can be pressed into the insert 3 of at least section cylinder well.
