Description
The present invention relates to the peristaltic pump for conveyance fluid, this peristaltic pump includes stator and supporting rotor in the stator,
Wherein, being integrated with flexible hose in the stator, rotor includes that the transfer unit of radial arrangement, transfer unit extruding comprise fluid
Flexible tube section, wherein, under the effect of the electromotor being connected with rotor, in flexible pipe, extruded fluid section gradually moves.
Peristaltic pump (also referred to as hose squeezing pump or peristaltic pump) is positive-displacement pump, and wherein, medium to be conveyed is by soft
The outside mechanically deform of pipe is pushed into flexible pipe.Such peristaltic pump is such as known from DE 10 2,008 002 761 A1.So
And, the shortcoming of these pumps is when squeezing tube, produces high frictional force between flexible pipe and transfer unit.Due to rubbing that these increase
Wiping power, drives the actuating device of the rotor of peristaltic pump and flexible pipe itself all to bear relatively HD.
It is an object of the invention to provide the peristaltic pump with long service life, prevent from passing in the running of peristaltic pump
Dynamic device and pumped (conveying) medium flexible pipe are undermined.
Seen by the peristaltic pump of the feature according to effective claim 1 and can realize this purpose.Dependent claims relates to excellent
The embodiment of choosing.
Peristaltic pump according to the present invention includes stator and supporting rotor in the stator, wherein, is integrated with in the stator and scratches
Property flexible pipe, rotor includes the transfer unit of radial arrangement, and the flexible tube section comprising fluid is extruded by transfer unit, wherein,
Under the effect of the electromotor being connected with rotor, in flexible pipe, extruded fluid section gradually moves.According to the present invention, transfer unit is
The rolling element being rotatably mounted, rolling element includes at least two roller support, and the outer shroud of roller support is by common shell
Connecting, the internal ring of roller support is connected to rotor, and wherein, under the effect of electromotor, rotor moves in the stator, transfer unit
Outer shroud roll on the inner surface of stator.
Roller support (also referred to as ball-frame carriage) is such a bearing, and two parts (are referred to as " internal ring " wherein
" outer shroud ") can be moved relative to each other and be separated by rolling body.Roller support is used for the radial force on axis of support and axle
And axial force, and it is intended to minimize energy loss and the abrasion caused by friction.At three kinds of i.e. internal ring of main parts, outer shrouds
And roll and mainly produce rolling friction between body.Owing to the rolling body in internal ring and outer shroud optimizes profit on hardening steel surface
Roll, so the rolling friction of these bearings is relatively low slidingly.
Describe the present invention the most with reference to the accompanying drawings.In the accompanying drawings:
Fig. 1 is the schematic diagram of the pump head of the peristaltic pump according to the present invention,
Fig. 2 is the schematic diagram along the A-A hatching of Fig. 1 of the conveyer device according to the present invention.
Fig. 1 illustrates the peristaltic pump 1 for conveyance fluid.Peristaltic pump includes stator 4, in the stator 4 with the most rounded (about
Be 360 °) track be integrated with flexible hose 3.As illustrated by the arrows in fig. 1, rotor 5 supports in the stator 4.Rotor radial ground
It is disposed with transfer unit 2a, 2b and 2c.The section 10 of transfer unit 2a and 2b squeezing tube 3.Electromotor (being not illustrated in detail) with
Rotor 5 acts on jointly, makes extruded fluid section 10 in flexible pipe 3 gradually move according to the direction of arrow indication especially.Therefore,
Fluid in section 10 is transported to the outlet A of peristaltic pump 1 from the entrance E of peristaltic pump 1.Certainly, conveying is also dependent on arrow indication
The rightabout in direction is carried out.In this case, peristaltic pump 1 can be used for pumping and suction.
The flexible pipe 3 being positioned in the entrance E of peristaltic pump 1 and outlet a-quadrant is fixed in hose clip 9, wherein, hose clip 9 with
Stator 4 connects.
Delivery hose 3 almost completely by stator 4 around and guide.It is achieved that the valve function of peristaltic pump 1.If rotor
5 leave unused, then at least two transfer unit 2 squeezing tube 3 so that fluid passage is blocked.
Fig. 2 illustrates the transfer unit 2 sectional view along the hatching A-A of Fig. 1 of the peristaltic pump according to the present invention.Transfer unit
2 include two roller supports 6a, 6b.Being each made up of internal ring 8a and outer shroud 7a in roller support 6a, 6b.Roll body 11
Between internal ring 8a and outer shroud 7a.The internal ring 8a of two roller supports 6a, 6b is securely coupled with each other and is securely connected to
Rotor 5.The outer shroud 7a of two roller supports 6a, 6b is connected with each other and is formed a kind of shell 7 of transfer unit 2.Rotor 5 and shell
Do not connect between 7.Thereby, it is ensured that shell 7 is installed rotationally around axis D.
Fig. 2 also illustrates that stator 4 and the flexible pipe 3 being extruded between stator 4 and shell 7.
Roller support 6a, 6b are connected with common shell 7, which prevent the inclination of the outer shroud 7a of roller support.Additionally, it is soft
Tube pump can adapt to different hose strengths or pump pressure by changing the thickness of shell 7.Additionally, shell 7 provides for flexible pipe 3
Smooth outer surface.Therefore, roller support 6a, 6b, flexible pipe 3 and the service life of actuating device are added.Therefore, at flexible pipe
In the pumping of pump 1 or suction running, each in transfer unit 2a, 2b and 2c rolls on flexible pipe 3 and does not almost have
There is frictional force.
