Definitions
- the invention relates to a pump designed as a positive displacement pump or a rotary lobe pump.
- the main fields of application of such viscous and viscous products are found in the chemical, pharmaceutical and food processing industries.
- a pump of the type mentioned has a rotor which is rotatably mounted on a drive shaft which can be connected to a motor drive.
- the rotor has a radially projecting, wave-shaped rotating rotor collar.
- the pump inlet and outlet are separate.
- the inlet communicates with a suction space and the outlet with an outlet space in the interior of the pump housing.
- Intake and outlet space are connected to each other via a pump channel.
- the slide which can be adjusted in the axial direction by means of the rotor collar, lies sealingly on both sides of the rotor collar.
- the slide rests on the slide guide supporting it.
- the slide guide is in turn sealing against the circumferentially surrounding, non-rotating parts of the pump. The sealing of the slide guide is achieved by its linear contact with the rotating parts of the pump surrounding it.
- the object of the invention is to provide an improved pump of the type mentioned at the beginning.
- This invention is given by the features of the main claim. Useful further developments of the invention are the subject of further claims following the main claim.
- the pump according to the invention is distinguished by the fact that the slide guide does not bear directly but indirectly via corresponding sealing bodies on the non-rotating pump parts surrounding it.
- These sealing bodies are present at least in some areas. For example, they cannot be present in the area of the slide guide that requires the groove-like opening for the rotor collar that projects through the opening and moves back and forth in the axial direction.
- a sealing body is present between the slide guide and at least the cover, the jacket wall and the rear wall of the housing.
- a sealing body can also be present in some areas in the inner rotationally fixed pump parts adjoining the slide guide in the radial direction.
- Such a sealing body can be realized by a cord-like sealing body, which is partially recessed in a correspondingly encircling groove in the slide guide.
- At least one cantilever pin can project from each of the axially opposite end faces of the slide guide, each of which engages in a corresponding recess in the cover or the rear wall. In this way, a tilt-proof and positionally fixed positioning of the slide guide in the pump housing can be made possible.
- the full surface of the slider guide cannot be provided as the respective sliding surface of the slider, but only strip-like surface areas can be provided are formed on the corresponding surface of the slide guide, which are to serve as sliding surfaces for the slide.
- the sealing body can be deformed elastically and can also be expanded pneumatically or hydraulically.
- a longitudinal groove running parallel to the adjustment direction of the slide can be present in it, as is also shown in the drawing.
- Cantilever members engaging transversely in this longitudinal groove can be present from the housing.
- Such a cantilever can, for example, be attached to the jacket wall of the pump housing. The slide itself therefore does not need to be in direct contact with the wall.
- Abutments supporting it transversely to the axial direction can also be present in the radially inner region of the slide.
- Such abutments which can also be realized by means of, for example, two retaining pins, can be projecting from the two non-rotatable bushes adjoining the hub of the rotor in the axial direction.
- the cross section of the slide guide shown as an example in the drawing approximates the shape of a trapezoid.
- an effective interaction between the slide and its slide guide can be produced by means of a slide which has a cross-section approximating the shape of a parallelogram, at least in its central region in the axial direction.
- the slider can be beveled flat or curved on its front and rear end faces in the axial direction, which further increases its sliding ability.
- FIG. 2 shows a vertical section through the pump according to FIG. 1 in the region of the slide and its slide guide
- FIG. 3 is a perspective view of the slide guide and the slide in a first slide position
- Fig. 4 is an illustration corresponding to FIG. 3 with a slide in a second slide position.
- the pump 10 shown in a horizontal section in FIG. 1 has a housing 12 that is rotationally symmetrical about the axis of rotation 30.
- This housing 12 has a rear wall 14 and a cover 28 spaced apart in the axial direction 31 parallel to the axis 30.
- a jacket wall 24 is integrally formed on the rear wall 14.
- the jacket wall 24 is closed by the cover 28, which bears axially against the bottom wall 26 of the jacket wall 24, which is lower in FIG. 1.
- the sealing contact of the cover 28 on the casing wall 24 is brought about by a plurality of circumferentially distributed studs 33 which pass through the cover 28 from the outside and are screwed into the rear wall 14 at the end.
- a drive shaft 60 protrudes centrally into the housing 12 from the outside and can be rotatably driven around its axis 30 outside the housing 12 by means of a flanged motor drive.
- a rotor 70 is seated on this drive shaft 60, which has a rotor collar 120 rotating in the radial direction.
- the rotor collar 120 runs in a wave shape around the rotor hub 74 of the rotor 70.
- the rotor collar 120 thus occupies a light space in the axial direction 31, which is provided by the width 125 of the pump channel 124 formed in the lower region of the housing 12 between a left and a right stator half 132, 134.
- the rotor collar 120 lies in a sealing manner on one of the side walls of the pump channel 124 that lie opposite one another in the axial direction and thus promotes this Pumped medium from the inlet, not shown in the drawing, to the outlet of the pump 10, which is separate from it.
- a slide guide 162 which tightly separates the spaces within the housing 12 which are respectively connected to the inlet and outlet and which are each connected to the pump channel 124.
- This slide guide 162 lies close to the jacket wall 24, to the rear wall 14 and to the cover 28 by means of a sealing body 510.
- this sealing body 510 is also present on the radially inner end wall of the slide guide, which is lower in FIG. 2, outside the opening 512 (FIG. 3).
- This opening 512 is so large that the rotor collar 120 does not hit the reveal walls of the opening 512 during its rotational movement.
- the opening 512 is arranged centrally in the axial direction between the rear wall 14 and the cover 28 and thus also centrally in the slide guide 162.
- the slide guide 162 has in the region of its upper end face 514, in its two lateral end faces 516 and 517 opposite in the axial direction and in the two axial end regions 518 of the lower end face 520, of which only one axial end face 518 is shown in FIG. 3, a circumferential groove 522.
- the upper groove section 522.1 has a groove base 524 in the form of a symmetrical saddle roof.
- the regions of the upper groove section 522.1 adjoining the lateral end surfaces 516, 517 are thereby formed deeper in the slide guide 162 than is the case in the upper middle region of the upper end surface 514.
- the groove base runs parallel to the respective end face.
- a constant deep groove section is also present in the area of the axial end areas 518 of the lower end face 520.
- a longitudinal bore extends above the opening 512 and parallel to the upper end face and in the axial direction centrally through the slide guide 162 525.
- the shaft 526 of one of the stud screws 33 passes through this longitudinal bore 525.
- a cantilever pin 528 protrudes at right angles from the lateral end face 516 below this longitudinal bore 525.
- a comparable cantilever pin protrudes from the opposite side face 517. The respective cantilever pin 528 engages in corresponding recesses in the cover 28 or the rear wall 14.
- the sealing body 510 (FIGS. 1, 2) lies in one piece in the circumferential groove 522 and protrudes from the groove 522.
- the cord-like sealing body 510 in the present case has one end in the one axial end region 518 shown in FIG. 3. It then runs along the lateral end face 516, along the upper end face 514, along the other lateral end face 517 and ends in the The other axial end region 518, not shown in the drawing in FIG. 3, thus ends in the immediate vicinity on both sides at the opening 512.
- the roof-shaped groove 522 in the area of the upper end face 514 also requires a sealing body 510 of correspondingly different cross-section in the area of the upper end face 514 Sealing body 510 is compressed in the area of the upper groove section 522.1 and pushed through the saddle roof-shaped groove base 524 against the casing wall 24 - upwards in FIG. 3.
- a good seal of the sealing body 510 is achieved not only in the area of the cover 28 and the rear wall 14 but also in the area of the jacket wall 24.
- a good seal is also achieved in the area of the axial end areas 518 and thus against the circular cylindrical jacket surfaces of the sleeve-shaped, non-rotating pump parts present there adjoining the rotor hub in the axial direction.
- the slide guide 162 thus represents a good seal between the inlet area and the outlet area of the pump, with the exception of the opening 512.
- This slide 182 is secured in its side tight contact with the slide guide 162 by upper and lower retaining pins 530, 532.
- Two upper retaining pins 530 protrude inwardly projecting from the jacket wall 24 into a longitudinal groove 534 which is present on the radially outer end face 536 in the axial direction 31.
- the slider 182 is supported by two retaining pins 532, which project radially protruding from rotationally fixed sleeve parts, each of which adjoins the rotor hub on both sides in the axial direction.
- the rear side 538 of the slide 182 lies against an upper and lower strip-like surface area 540, 542 of the slide guide. Between the strip-like surface areas 540, 542 there is a plate-shaped depression 544 in the said outside of the slide guide. As a result, only relatively small surface areas need to be designed to be slidable. In addition, the plate-shaped depression 544 brings about a pressure relief.
- the holding pins 530, 532 are present in the transverse direction (FIG. 2) on both sides of the slide guide 162 in a comparable manner.
- the slide 182 can be placed on the slide guide 162, both on the left and on the right side.
- the slide 182 is placed on that side of the slide guide 162 in such a way that it is present on the pressure side, and thus in the region of the outlet.
- the slide is pressed against the slide guide 162.
- the retaining pins 530 engaging radially from the outside in the longitudinal groove 534 of the slide 182 furthermore ensure that the slide is in each rotary position of the pump 10 sealing system on the slide guide 162 does not lose and does not drop outward in the event of an overturned arrangement of the rotor hub.
