Definitions

  • Rotary systems can be used both in conveying fluids and creating a circular movement from liquids in motion
  • the pumps used m rotary system are significantly different from positive- displacement (reciprocal) pumps and dynamic (centrifugal) pumps although they have numerous types
  • positive displacement pumps according to tlie classification of pumps They have some similarities with dynamics pumps because of their circular movement If there is high pressure and lower rotation dynamics pumps are inadequate since their productivity decreases in lower speed In fact after a certain point these pumps will not work Tl e rotary pumps are good solution in cases demanding low rotational speed and high pressure
  • the liquid volume passed throughout the pump is constant per unit rotation This volume does not change according to rotational speed
  • To change the quantity of flow tlie rotational speed of the pump has to be changed This causes some difficulties m systems having constant speed
  • the following rotary system which we claim to protect it, has a special apparatus to prevent this problem The flow can be adjusted without any friction inside or outside of the system
  • the proposed system has two mam differences from ordinary rotary pumps In the proposed system there is a rotor/cover pair, in contrast to classic rotary systems that have just a simple rotor In this system, the rotor is placed into a rotor follower cover The rotor and rotor follower cover rotate circularly around the same axis The other difference m the proposed system is that there is an additional movement parallel to the axis of principle rotation An auxiliary apparatus moves the rotor and cover back and forth (Hereafter, this movement will be called as "sliding, or to slide") This special movement along the axis is only used when the volume needs to change The rotational speed does not need to change, it stays constant

Abstract

Le système rotatif selon cette invention autorise un réglage du volume entre rotors (6, 9) dans des systèmes rotatifs internes et externes à lobes ou engrenages. Dans les systèmes rotatifs classiques, le volume entre les rotors et le carter est constant et il est impossible d'agir sur le flux traversant le système sans changer la vitesse de rotation, cela n'étant possible qu'au moment où la vitesse s'accélère. Dans le système selon cette invention, il est possible de régler le volume et d'agir sur le flux en fonctionnement et ce, même si la vitesse de rotation des rotors est constante. Ce système se compose des composants d'un système rotatif classique, carter, arbres, rotors, etc., et de constituants spéciaux propres, en l'occurrence les enveloppes de suiveur de rotor (7) et les éléments de garnissage (5). Le flux est assuré par une cavité entre le carter, les rotors et les enveloppes. Les rotors et les enveloppes de suiveur de rotor (7), qui tournent ensemble autour d'un axe, sont également capables de se déplacer relativement près les uns des autres. Les rotors peuvent coulisser à l'intérieur des enveloppes (7). Ce mode de fonctionnement permet d'agir sur le volume cavitaire ainsi que sur le flux traversant le système et ce, sans modifier la vitesse de rotation.
