Definitions
- the invention relates to a rotary piston machine according to the preamble of Claim 1.
- Rotary lobe machines with three-bladed rotors are as roots blowers known.
- the inlet and outlet are together aligned on a line that is perpendicular to the axes of the rotors.
- the volume flow is through the interlocking wings in the chamber transported and pushed out at the outlet without internal compression.
- Such Rotary lobe machine is particularly useful as a charger for relatively high volume flows suitable.
- DE-A-2 422 857 describes a rotary lobe machine of the generic type known, with two three-bladed rotors, which are offset by parallel Rotate the axes in opposite directions and comb them without contact as well as with the Circumferential wall of the chamber form separate cells, the claw-like wings of the rotors with the chamber at the same time through the Rotation of the rotors and their volume increasing suction cell Rotation of the rotors form their volume-reducing pressure cell. Furthermore is off GB-A-818 691 discloses a rotary vane pump in which between inlet and outlet formed a charging cell connected to a charging port becomes.
- the claw-like form Wing of the rotors with the chamber at the same time by rotating the Rotors their volume increasing suction cell and a by rotating the Rotors pressure cell reducing their volume. Since the rotary lobe machine with inner compression and at the same time working with inner expansion, it is for suitable for the simultaneous generation of pressure and negative pressure. Furthermore, the Rotors with chamber two initially in the course of the rotation of the rotors separate charging cells that continue to rotate the rotors be combined with each other to form the pressure cell. Over the charging cells one can Media stream are fed in, so that at the pressure outlet a corresponding increased volume flow is available. The charging cells become essentially isobar and isochoric in the Pump chamber moved; the one in the charging cells Medium essentially experiences during the displacement of the charging cells no pressure and no volume change.
- the geometry of the rotors is determined by the requirement in the chamber simultaneously for the generation of pressure and vacuum differentiate required cells. Because the rotors contactless with each other and also with the peripheral wall of the chamber interact, no wear occurs in the area of the chamber.
- the sealing gap between the rotors can be optimized by optimizing their Geometry can be kept very small; in the case of practical ones Designs only fractions of a millimeter, so that good printing and Vacuum values are guaranteed. These values are even increasing Operating time better, since the build up over time Deposits lead to a reduction in the size of the sealing gap.
- the rotary lobe machine according to the invention is particularly suitable for Use as a pump for the simultaneous generation of compressed air and Vacuum.
- it is particularly suitable for use in suitable for the paper processing industry, especially if none separate provision or setting of compressed air and vacuum is required.
- Compressed air is e.g. to blow on one side Stacks of paper needed to support sheet separation.
- the pulsating compressed air generation by such a pump proves to be here as useful because the paper edges due to intermittent Compressed air can be separated more easily.
- the rotary lobe machine according to the invention is below Example of a pump for the simultaneous generation of compressed air and Vacuum described. However, the invention is for such an application not limited.
- the single-stage pump for the simultaneous generation of Compressed air and vacuum has a housing that consists of a load-bearing Middle part 10, one on one side of the middle part 10 attached housing cover 12, one on the other side of the Middle part 10 attached housing ring 14 and one on the housing ring 14 adjoining cover plate 16. Between the middle part 10, the housing ring 14 and the cover plate 16 is a pump chamber 18 educated.
- a pump chamber 18 educated in the opposite wall parts of the Housing cover 12 and the middle part 10 are two shafts 20, 22 flying parallel to and offset from each other in ball bearings stored.
- the pinion 24, 26 are in meshing engagement with one another so that the shafts 20, 22 rotate synchronously in opposite directions.
- For the rotary drive is the lower shaft 22 led out of the housing cover 12.
- each rotor has 30, 32 three wings 30a and 32a.
- the pump chamber 18 has the side view Form of two intersecting circles, joined together in the form of an "8" are.
- the blades 30a of the rotor 30 have a shape that the shape of the blades 32a of the rotor 32 is different.
- the geometry the wing 30a, 32a and the pump chamber 18 is determined so that at the rotation of the rotors 30, 32 a plurality of separate cells be formed, as with reference to Figures 4a to 4h further explained in more detail below by using the wings 30a, 32a without contact a sealing gap of a fraction of 1 mm above and along slide the outer periphery of the pump chamber 18.
- the cover plate 16 is with a series of recesses provided to the outside by a patch plate 36th be completed.
- the closure plate 36 are two pipe sockets 42, 44 screwed in.
- the upper pipe socket 42 forms the suction connection and is connected to a recess 50 of the cover plate 16.
- the lower pipe socket 44 forms the pressure connection and is with a Recess 52 connected in the cover plate 16.
- Two more Recesses 54a, 54b in the cover plate 16 are to the outside Atmosphere open and form charging ports.
- Figure 4a shows the rotors 30, 32 in a rotational position in which their wings 30a, 32a with the wall of the pump chamber 18 a closed, only common to the recess 50 Form cell 60.
- This cell 60 enlarges in the further Rotation of the rotors 30, 32 their volume, as can be seen in Figure 4b.
- This cell 60 is therefore a suction cell.
- FIG. 4c shows two cells 62a, 62b which are separate from one another arise immediately after the state shown in FIG cell 60 was separated into two sub-cells.
- the rotor 30 assigned cell 62a already borders the recess 54a, and the Cell 62b associated with rotor 32 approaches recess 54b.
- Figure 4d are the cells 62a, 62b with those leading to the atmosphere Recesses 54a and 54b in connection and are filled with air and charged to ambient pressure so that the air mass flow increases becomes.
- the cells 62a, 62b are thus charging cells.
- the pump chamber 18 is free of any lubricant because the Work rotors 30, 32 without contact. To the drive side is the Pump chamber 18 sealed by seals on the shafts 20, 22.
- the housing can be equipped with cooling fins for cooling be, and arranged on the side of the housing cover 12 Cooling fan is cooling air from the cover plate 16 over the Housing ring 14, the middle part 10 and the housing cover 12 out.
- a resonance damper is used to dampen the operating noise, which is matched to the operating frequency of the pump. This frequency is due to the three-bladed design of the rotors triple speed of the shafts 20, 22. The increased operating frequency facilitates the accommodation of the resonance damper because of its length is reduced accordingly.
- the described flying storage of the rotors is advantageous up to a volume flow of about 300 m 3 / h.
- Pumps with a larger volume flow are preferably designed with rotors mounted on both sides. In this case, connections are left in both side plates.
