Definitions
- Drying compressors are gaining in importance in industrial compressor technology, because increasing obligations in environmental regulations and rising operating and disposal costs and increased demands on the purity of the medium, the known wet-running compressors, such as liquid ring machines, rotary vane pumps and oil or water-injected screw compressors, increasingly replaced by dry compacting machines. These machines include dry screw compressors, claw pumps, diaphragm pumps, piston pumps, scroll machines and Roots pumps. However, these machines have in common that they still do not meet today's demands in terms of reliability and robustness and size and weight with low price level and satisfactory efficiency.
- dry-compressing spindle machines can be used for both vacuum and overpressure applications, the power requirement in the overpressure is naturally significantly higher, because in the overpressure range with final pressures well above 2 bar (absolute) up to 15 bar and even higher significantly greater pressure differences to be overcome.
- the object of the present invention is to significantly improve the efficiency and the compressibility for dry compressing 2-shaft rotary displacement machines for conveying and compressing gaseous media for applications in vacuum and in overpressure.
- this object is achieved in that for vacuum and overpressure applications in a dry-compressing spindle compressor as a 2-shaft displacement machine in opposite directions from an outer, so located outside of the compressor working space, synchronization rotation angle driven pair of rotors from a 2-toothed spindle rotor and a toothed intermeshing 3-toothed spindle rotor with a wrap angle with respect to the 2-toothed spindle rotor of at least 800 angular degrees, but preferably over 1160 degrees, conveniently even more than 1700 degrees, or even better over 2600 degrees and even for very high pressure differences even over 3500 degrees, because the higher the compressibility is to be, the greater the wrap angle to choose, the Spindeirotore operated at high speed such that the average rotor head peripheral speed is a range of at least 30 m / sec, better 45 m / sec, but desirably more than 60 m / sec or better still more than 80 m / sec is achieved, because the higher the
- the rotor head circle arc angle on the 2-toothed spindle rotor is preferably carried out in each end cut such that this head circle arc angle is greater than the respective rotor 2-sided Compressor housing opening angle is.
- each spindle rotor is fixedly mounted on its own carrier shaft, each carrier shaft accommodating inter alia the coolant supply, ie the external synchronization and the bearing.
- the outer diameter of the gear-side rotor bearing on the 2-toothed spindle rotor is made larger than the outer diameter of the synchronization gear of the 2-toothed spindle rotor, so that the 2-toothed Spindle rotor as a rotation unit completely assembled and ready to be balanced.
- the manufacture of the profile contour flanks which differ in particular in the rotor longitudinal axis direction, takes place successively by turning individual point sequence helical lines in the rotor longitudinal axis direction, which then finally produce the profile flanks.
- the flow resistance for the leakage return flow is increased by grooving preferably all top circular arcs on both spindle rotors.
- the spindle rotor pair of a material with higher heat conductivity, preferably aluminum alloy on steel support shaft, the compressor housing is then preferably also an aluminum alloy.
- the "wrap angle" on the spindle rotor is the sum of all twist angles along the spindle rotor axis between the individual cross-sectional profile contours, which result overall in the rotor longitudinal axis direction as the z-axis value progresses.
- both end-cuts are one to another according to the selected z (phi) function for precisely that step of z, after z i + 1 known angle phi, twisted.
- the number of completed working chambers at the spindle rotor pair between the rotor inlet side and the rotor outlet side is considered as "number of stages".
- the aim is to achieve an integer number of steps as far as possible.
- the PHI.2 value is rounded up to at least the next 10th digit, ie z. From 2411 ° to 2420 °
- a “working chamber” is closed for the pair of rotors tooth space volume, which is limited by the surrounding compressor housing and the spindle rotor profile back flanks between the defined according to toothing profile contour interventions, these engaging rotor pair profile flanks are considered as touching, so close to zero distance , Practically, however, the engaging rotor pair profile flanks have a certain, albeit minimal, distance, resulting in an internal leakage return flow.
- the "working chamber volume on the inlet side” is the volume of the first working chamber closed on the suction side
- the “working chamber volume on the outlet side” is the volume of the last closed working chamber in front of the conveying gas outlet. The quotient of these two volumes represents the "internal compression ratio".
- Values over 3 can be suitably defined as "higher internal compression ratios”.
- the volume of a working chamber is calculated from the respective working area cross-sectional area multiplied by the stepwise working chamber extent defined by the spindle pitch in the rotor longitudinal axis direction.
- the spindle rotor pair axes are always parallel with a constant distance, the so-called.
- “Axle distance” represents an important parameter of the screw compactor machine.
- the "external synchronization" of the two spindle rotors is required because the rotor pair operates in the compressor working space without operating fluid, ie "dry compressing" is operated, and therefore because of the high speeds rotates without contact with the least possible edge distance to each other in opposite directions.
- the two spindle rotors are constantly driven with high, accurate in the range less minute minutes rotation angle accuracy, which is known to be carried out via external synchronization.
- the most common design for external synchronization is via directly meshing spur gears whose rolling circles are just as large as the toothed rolling circles of the respective spindle rotor delivery threads. But there is also, for example, the possibility of electronic rotor pair synchronization by each rotor is driven by his own engine electronically true to the angle of rotation.
- the "inlet area” can be described by means of the wrap angle area, with the inlet side the first closed working chamber through progressive angle of rotation arises. In the case of this spindle rotor pair according to the invention, this starts from the inlet end-cutting side starting at 720 degrees of angle plus the head arc angle qa. KB2 on the inlet side of the 2-toothed spindle rotor.
- the term "overpressure” is defined as absolute pressures of at least 2 bar, usually 8 bar to 15 bar, but with a high number of stages, pressure values of more than 25 bar can be achieved. With non-atmospheric aspiration, these values shift accordingly.
- the term “vacuum” or negative pressure is understood as meaning ultimate pressures as absolute pressure values of less than 50 mbar, better still less than 1 mbar and with a corresponding number of stages even below 0.01 mbar absolute versus outlet pressure, which lies in the atmospheric pressure range.
- Said "desired minimization of the temperature differences” is based on the fact that the core components active in the compressor working space, ie the pair of rotors in the surrounding compressor housing, should operate with as small a distance as possible in order to limit the internal backflow within reasonable limits hold.
- the differences in thermal expansion for said core components should be kept as low as possible in order to control the gap backflows to be able to.
- the thermal expansions in addition to the material properties in the present geometry are essentially determined by the component temperatures, the temperature differences between the core components are consequently to be kept as low as possible.
