The cutaway section structural schematic diagram arrived.
Specific embodiment
The utility model is described in further detail below with reference to embodiment.
Embodiment 1
As shown in Figure 1, a kind of support construction for the pump installation with rotatable cavity, including rotatable cavity
100 shafts 200 for being fixedly connected and rotating with the cavity 100 and the reception pipe 300 static relative to the cavity 100；
Wherein,
The cavity 100 is rotated along a predetermined direction 400；The predetermined direction 400 is the axial direction side that cavity 100 rotates
To.It would generally consider that the predetermined direction 400 is arranged in the horizontal direction, but can also will have a vertical angle with horizontal direction
Direction as the predetermined direction.The cavity 100 refers to the dress that a cavity 102 is had made of the material using hard
It sets, the interior shape and size of the cavity 102 are adapted to neat liquid or only carry the outstanding of a small amount of solid component
Supernatant liquid rotates in cavity 102.Liquid in cavity 102 is inputted by an import 103, and by being arranged in reception pipe 300
Outlet 104 exports, and typically, the import 103 for inputting liquid is arranged in axially extending section 301 on cavity 100 and receives
Gap between pipe 300 enters cavity 100, after liquid enters cavity 102, due to the rotation of cavity 100, and is arranged in cavity
Similar blade in 100 interior walls or the device of other structures drive the liquid in rotation in cavity 100.The liquid of rotation generates
Centrifugal force, and exported by reception pipe 300.If cavity 100 is cut by the face perpendicular with predetermined direction 400, chamber
The cross sectional shape of 100 internal cavity 102 of body is generally circular.In addition, the volume size of cavity 102 can be adjusted optionally
It is whole.
The shaft 200 is extended up to along the predetermined direction 400 to be connected with one end of the cavity 100；Shaft
200 other end usually connects power mechanism, such as engine, motor or other similar devices.Shaft 200 and cavity
It is usually to be attached by attachment devices such as bolts between 100, can when needed removes cavity 100 in this way.?
Under the support of special process, shaft 200 and cavity 100 can be integrated.In actual manufacturing process, may be used also
Cavity 100 can be segmented, it, can be by cavity 100 due between cavity 100 and there is no the components that are mutually shifted
It is separated, and is passed through in structure close to one end of reception pipe 300 or at least part and the other parts of cavity 100
The attachment devices such as bolt are fixedly connected to form a complete cavity 100.Shaft 200 is generally placed at one and is provided with
On the pedestal of bearing arrangement, if also having shell 600, which can be arranged on shell 600, or directly pass through
Support device B501 as shown in the figure realizes connection.It is basic since shaft 200 is only the rotation along predetermined direction 400
Other structures are not needed.Further, since further comprising support device A500 in the present embodiment structure, therefore held in shaft 200
The power received is more uniform, reduces required precision needed for 200 processing and manufacturing process of shaft.
The reception pipe 300 includes axially extending section 301 and radially extends section 302；It radially extends section 302 and axial direction
Extended segment 301 forms the structure for being technically known as Pitot tube, and the outer shape for radially extending section 302 is designed to similar streamline
The blade form of type advantageously reduces the loss that the liquid in cavity 100 flows through caused kinetic energy when radially extending section 302.This
The specific structure for the reception pipe 300 that embodiment is recorded can improve in the structure of existing Pitot tube to be obtained.It is rotated in cavity 100
Afterwards, the opening for radially extending 302 end of section of reception pipe 300 is entered with the liquid that cavity 100 rotates by being arranged in reception pipe
Channel in 300 axially extends the direction output of section 301.In addition, reception pipe 300 is quiet relative to the cavity 100 of rotation
It is only motionless.Reception pipe 300 documented by the application is stationary to be should be understood as with reception pipe 300 as reference, then cavity
100 be rotation, and reception pipe 300 is stationary.
Described axially extending section 301 is extended up to along the predetermined direction 400 by the cavity by the reception pipe 300
100 form relative to one end far from the shaft 200 into the cavity 100, are used in axially extending section 301 with one
The pipeline of liquid flowing, the conveying and output of the liquid for radially extending the entrance of 302 distal opening of section from reception pipe 300；Institute
State radially extend section 302 by the reception pipe 300 enter the cavity 100 after towards the cavity 100 rotation radial direction side
To continuing to extend to form.
It especially, further include the support device for being set to the cavity 100 relative to one end far from the shaft 200
A500；The support device A500 is for supporting cavity 100.Support device A500 is used to provide support for the cavity 100 of rotation
And friction is reduced, in addition, provided support can reduce the vibration of one end close to reception pipe 300 of cavity 100, reduce
Suffered torque in shaft 200.One end of support device A500 is connected with cavity 100 or cavity extended segment 101, another
End can be installed on a fixed position or it is as follows documented by be mounted on shell 600.
In embodiments herein, as a kind of optional scheme, the cavity 100 includes cavity extended segment 101；Institute
State axially extending section 301 outside that cavity extended segment 101 is socketed on the reception pipe 300；The support device A500 is located at institute
State the position of cavity extended segment 101.
It further include the shell static relative to the cavity 100 as a kind of optional scheme in embodiments herein
Body 600, the shell 600 are normally held on the fixed attachment in ground or ground；The shell is sheathed on the cavity
Outside；The shell 600 passes through support device A500 and the support device B501 and the chamber that are set in the shaft 200
Body 100 is connected.In general, shell 600 for the rotation of cavity 100 and shaft 200 be do not have it is influential, but in order to
Preferably shaft 200 and cavity 100 are supported, then support device is directly connected with shell 600.Shell 600 along turn
