For being encased in receiving member, such as shell, wherein receiving member is provided with for drawing fluid by pump insert and receiving
The suction passage in chamber that part is constituted.This pump insert is also referred to as used as cartridge-type pump or boxlike to 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 simply and be at low cost provided in receiving member, the suction passage
Geometry need not be constituted in a manner of flow optimized, however thus fluid cannot ideally flow in the case where no insert
It is dynamic, and it is for example easy foaming, this can negatively affect the service life of this pumping unit.
Improvement project of the invention provides in the dependent claims, the description and the figures.
In one preferred embodiment, receiving member constitutes reservoir for holding a fluid.
Here, receiving member is preferably able to be gear mechanism housing.The inner cavity of gear mechanism housing, which is formed, is used for fluid, such as
Container for oil.Pump insert is fitted into gear mechanism housing wall, wherein constituting 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 during being poured receiving member together.Since when core or sliding block shape, channel geometry
Structure is main influence, so suction passage can not constituted optimally for the sucking of fluid.
According to the present invention, pass through the geometry of suction passage not optimized and the fluid due to foaming at high speed
It can result in cavitation this actual conditions in pumping unit, be packed into insert in suction passage according to the present invention.?
This increases to the particularly preferred machining of suction passage, preferably in the region of the inlet hole of pump insert 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, when demoulding to realize casting mold,
The region can be also made up of casting.
In one embodiment according to the present invention, insert is manufactured by plastics.
Insert preferably manufactures in injection moulding herein.
Injection moulding allows the manufacture of the low cost of complicated geometry.
In one preferred embodiment, pump insert is configured to vane pump to pumping unit in turn.
Vane pump and then pump insert mainly include rotor and contour loop, and there are the rotor one or more settings to exist
Blade in the gap of rotor, wherein rotor is anti-lost, such as by means of retainer ring, and drive shaft is torsionally arranged in
On.It is provided with the first pressing plate and the second pressing plate on the driving shaft, wherein rotor, at least one blade and contour loop are arranged in pressing plate
Between.
Alternative can for example be configured to gear pump in vane pump, pump insert.
Pump insert is inserted into the blind hole of receiving member.It is fixed on receiving member in order to which pump insert to be kept in position
There is lid, middle cover is pressed against the wall portion of receiving member and is kept in position.
Pump insert has at least two sealing elements being separated from each other, and wherein sealing element is preferably configured as O-ring.One
In a preferred embodiment, equipped with the sealing element on the first pressing plate and the second seal on the second pressing plate, wherein
Sealing element of the sealing element by suction chamber relative to pressure chamber sealing and the second pressing plate on first pressing plate is sealed relative to lid, with
Just it prevents from leaking.
Detailed description of the invention
In the following, illustratively description is of the invention by referring to accompanying drawing.
Fig. 1 shows the sectional view of pumping unit as be known in the art；
Fig. 2 shows the sectional views of pumping unit according to the present invention.
Specific embodiment
Pumping unit 1 As be well known in the art is shown in FIG. 1.For clarity, pump insert itself is not shown, and
And the pump insert is set as being mounted in section A.In the shell for receiving, such as in transmission device, it is mounted with appearance
Part 2 of receiving wherein is constituted to 3 machining of suction passage equipped with the suction passage 3 for trandfer fluid in the receiving member.
The composition scheme of the machining of suction passage 3 and then inner face I design spick-and-spanly and processing can be realized pump and insert
The optimization for entering the fluid stream in the pump chamber of part, thus reduces or prevents the sucking of air.Injector is provided in suction passage 3
5。
Fig. 2 shows the pumping unit according to the present invention 1 in the shell formed by component, the shell provides receiving member 2,
Wherein pumping unit is also shown in a manner of not pump insert.Suction passage 3 is cast together in receiving member 2.This shell
The pouring technology explicit costs of component is lower, however inner face I is obviously more rougher than by means of the manufacture of cutting method.If it is assumed that being
Gear mechanism housing, significantly, oil conservator have been constructed in casting together as container B.
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 packed into suction passage 3
Stating insert improves fluid stream.
Insert has the shape of stem bar, and the stem bar extends to appearance from the outer diameter A D of the internal diameter I corresponding to suction passage
Receive the diameter D of portion A.In the component in suction passage 3 be cylindrical and until depth T is extended in suction passage 3.It is described
Embodiment is exemplary.Insert can also have cylindrical shape, and the cylinder terminates in section A ground connection
In or the insert there is the cylindrical that extend with arbitrary form, wherein for extension without necessarily achieving diameter D.
In a preferred implementation modification, by being equipped with midfeather, the fluid stream in insert 4 can be divided into
At least two become a mandarin.
Insert 4 according to the present invention is made of plastics, 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.
