Definitions

  • This invention relates to amechanism thatcan be usedin pumps to move (pump) fluids and it can be used in turbines for extracting energy from a fluid flow.
  • the small hollow drum is diagonally partitioned in the middle.There are openings at both the sides of this small drum. The fluid from one end does not directly pass to the other end.
  • the small drum is fixed to the web discslike a crank pin.
  • this mechanism When this mechanism is used as a pump, it sucks the fluid from one side and sends out to the other side. And whenused as a turbine, the fluid gives pressure to the both drums and makes them to move.
  • Fig - 1 is the plan view of this mechanism
  • Fig - 2& 3 are the basic shapes of the drums in this mechanism
  • This mechanism works as a crank mechanism.
  • a cam shaped hollow drum (1 1 ) is used as a crank pin in this mechanism. It is fixed with the crank web discs (14). This drum is diagonally partitioned (15) andtwo side openings (19) are made at its both sides.
  • the crank web discs (14), the small drum (1 1 ) and the shaft (20) are assembled as one piece (FIG -10, 12).
  • the shaft can be made bysolid rod orhollow pipe (FIG -12, 13)
  • the hollow pipe shaft helps the fluid to pass through the shaft to the small drum directly.
  • the crank web discs (14) shut the big drum's (12) end openings closely.
  • Theslide supports (13) are fixed to the big drum (12).
  • the slide supports can be of different models (FIG -4, 5, 6) depending upon the size and usage of the pump.
  • the big drum'sslide supports(13) are placed between the guide rollers (16).
  • the collar discs (26) hold the guide rollers properly.
  • the collar discs are fixed to the outer body (17)
  • Non moving fixed parts The cam shaped drum(11 ), two crank web discs (14) and shaft (20) are the rotating parts.
  • the big drum (12) and the slide supports(13) are the reciprocating parts.
  • Two collar discs (26) with guide rollers (16), outer body (17), shaft holding brackets (27), hubs (24)and inlet, outlet pipes (25) are the non moving fixed parts.
  • FIG -14 explains the movements of this mechanism.
  • the reciprocating drum At 0° the reciprocating drum is positioned at middle of its reciprocation length. One side of the space between the drums is expanded maximum and the other side is shrunken tominimum. From 0° and the 180°, the spaces between the drums start to increase and decrease.
  • the reciprocating part At 70° the reciprocating part reaches its end and up to 110° it stands at the same position. The reciprocating part moves only between110° to 250° and 290° to 70°.

Abstract

Cette invention se rapporte à un mécanisme de pompe à déplacement positif. Il peut être utilisé dans des pompes pour déplacer (pomper) des fluides et il peut être utilisé dans des turbines pour extraire l'énergie d'un écoulement de fluide. Il y a deux tambours qui travaillent ensemble, lorsqu'un premier tambour tourne, l'autre effectuer un mouvement alternatif. Il fonctionne comme une pompe à mouvement alternatif mais il n'y a pas de soupape utilisée dans ce mécanisme. Une grande quantité de fluide peut être pompée. Ce mécanisme peut être utilisé dans des pompes d'éolienne, des pompes à actionnement manuel, des pompes à boues, des pompes à pression, des pompes à huile dans des moteurs, etc. Ce mécanisme peut être utilisé dans une turbine à eau et il peut être installé dans des canaux, des chenaux, des rivières, etc. pour obtenir l'énergie ou pomper l'eau dans les zones surélevées. Ce mécanisme peut être utilisé pour pomper des fluides à viscosité élevée comme de l'huile pour engrenages (SAE 140 et plus), du miel, des pulpes, des boues, etc.
