Definitions
- the invention relates to a peristaltic pump for conveying fluids comprising a stator and a rotor mounted therein, wherein in the stator, a flexible hose is integrated, and the rotor has radially arranged conveying elements which press the hose over a portion containing the fluid and wherein under action a motor connected to the rotor, the compressed fluid section progressively moves in the hose.
- a peristaltic pump also referred to as a peristaltic pump or peristaltic pump, is a positive-displacement pump in which the medium to be pumped is forced through it by external mechanical deformation of a hose.
- Such peristaltic pumps are e.g. known from DE 10 2008 002 761 A1.
- a disadvantage of this pump is that when squeezing the hose high frictional forces between the hose and the conveyor elements occur. These increased frictional forces cause, on the one hand, the gearbox driving the rotor of the peristaltic pump and, on the other hand, the hose to be heavily loaded.
- the object of the invention is to provide a hose pump with a long service life, in which the transmission and the conveyor hose are spared during operation.
- the hose pump according to the invention comprises a stator and a rotor mounted therein, wherein in the stator, a flexible hose is integrated, and the rotor has radially arranged conveying elements which press the hose over a portion containing the fluid and wherein under the action of a motor connected to the rotor, the compressed fluid section progressively moves in the hose.
- the conveying elements are designed as rotatably mounted rollers which comprise at least two rolling bearings whose outer rings are connected via a common outer shell and the inner rings are connected to the rotor, wherein under the action of the motor, the rotor moves in the stator and the outer rings of the Roll off conveyor elements on the inner surface of the stator.
- Rolling bearings also referred to as ball bearings, are bearings in which two mutually movable components, the so-called inner ring and the outer ring, are separated by rolling bodies. They serve to support radial and axial forces in the case of axles and shafts and are intended to minimize the power loss and wear resulting from friction. Between the three main components inner ring, outer ring and rolling elements mainly occurs
- FIG. 1 is a schematic representation of a pump head of a hose pump according to the invention
- Fig. 2 is a view along the section A - A in Fig. 1 of a conveyor according to the invention.
- Fig. 1 shows a hose pump 1 for conveying fluids.
- the peristaltic pump comprises a stator 4, in which a flexible tube 3 is integrated on a substantially circular path (about 360 °).
- a rotor 5 is mounted in the stator 4.
- the rotor has radially arranged conveying elements 2a, 2b, 2c.
- the conveying elements 2 a, 2 b push off the hose 3 in the section 10.
- acts with the rotor 5 is not closer illustrated motor together, in particular the abridged fluid portion 10 progressively moves in the hose 3 according to the direction of the arrow.
- the fluid is conveyed in the section 10 from the inlet E of the hose pump 1 to the outlet A of the pump 1.
- a conveying direction opposite to the direction of the arrow can also take place.
- the peristaltic pump 1 can be used on the one hand for pumping and on the other for sucking.
- the hose 3 In the region of the inlet E and the outlet A of the pump 1, the hose 3 is fixed in a hose clamp 9, the hose clamp 9 being connected to the stator 4.
- the delivery hose 3 is almost completely enclosed and guided by the stator 4. As a result, a valve function of the pump 1 is achieved.
- the rotor 5 When the rotor 5 is at rest, at least two conveying elements 2 press the tube 3, so that the path for the fluid is blocked.
- Fig. 2 shows a sectional view along the section A-A in Fig. 1, a conveying element 2 of the pump according to the invention.
- the conveying element 2 comprises two rolling bearings 6a, 6b.
- Each rolling bearing 6a, 6b consists of an inner ring 8a and an outer ring 7a.
- the rolling rolling elements 11 are located between the inner ring 8a and the outer ring 7a.
- the inner rings 8a of the two rolling bearings 6a, 6b are fixedly connected to one another and to the rotor 5.
- the outer rings 7a of the two rolling bearings 6a, 6b are connected to each other and form a kind of outer shell 7 of the conveying element 2. Between the rotor 5 and the outer shell 7 is no connection. This ensures that the outer shell 7 is rotatably supported about the axis D.
- FIG. 2 further shows the stator 4 and the tube 3 squeezed between the stator 4 and the outer shell 7.
- the bearings 6a, 6b are connected to a common outer shell 7, which prevents tilting of the roller bearing outer rings 7a.
- the pump can be adapted to different tube thicknesses or Adjust pump pressures.
- the outer shell 7 the hose 3 has a smooth outer surface.
