Definitions

  • the invention is related to the field of mechanical engineering. According to the international patent classification it can be classified in the section of volume liquid machines. More specifically the invention belongs to the group of rotational chamber pumps defined with the sign F04C 18/00
  • the subjected invention provides a solution towards construction simplification and
  • this invention the process of pumping of the liquids is simplified as well many problems connected with the pumping of liquids.
  • this invention is simplification of the pump as a machine for doing that work - pumping liquids.
  • the subjected pump uses centrifugal power with an aim of creating pressure inside the rotational chamber which is essentially different from the existing centrifugal pumps in which the pressure is created between the impeller blades and the pump wall (frame).
  • the frame should not necessarily have strict form and dimensions in order to fulfill its function.
  • Another improvement acquired with this innovation is the integration of the rotational chambers into one disk with baffle plates with perforations at the edge of the disc, in which the liquid is under pressure. From there, the liquid flows out in a fixed pressure chamber or a . collection cover which is not under pressure.
  • the effect of this modification-which is not known in the existing types of pumps is considerable decrease in friction, which as a result increases the pump's efficiency.
  • pumps There are different types of pumps, hand operated pumps, electric pumps, or pumps driven by motor.
  • pumps with linear movement There are a lot of types of pumps divided into a lot of types or groups, for example: pumps with linear movement and pumps with rotational movement.
  • Example of linear movement pump is piston pump in several shapes and divisions made as hand pumps driven by electric motor or other type of motor drive.
  • Pumps with rotational movement can be for example: screw pumps, scroll pumps, centrifugal pumps.
  • Centrifugal pumps are presently one of most widely used pumps.
  • FIG. 1 Figure 1 and figure 2 on which schematic description of the rotational chamber pump is shown in two versions.
  • Rotational chamber pump shown on the figure 1 and 2 consists of intake pipe (figure 1 and figure 2, pos. 3) that rotates around its axe and throughout which the liquid of the reservoir (figure 1 and figure 2, pos.1) enters and can be regulated throughout the non-reversible valve, enters the pressure part of the pump (figures 1 ,2,3,4, pos. 4).
  • the most characteristic part of this invention is the pressure rotational part (figure 1 and figure 2, pos.4) which is consisted of rotational chambers (figure 3 and figure 4, pos.3) that can be with circular or rectangular cross-section. Rotational chambers are placed radially or curved toward the central axe around which the whole pump rotates. On this way the pressure part is balanced made of several numbers of rotational chambers.
  • the number of chambers is not limited and their disposition is made in the manner that several rotational chambers are placed under angle of 3607n degrees one toward another.
  • the fixed chamber can be pressurized (filled with liquid) or not pressurized (filled with air).
  • a disc is formed with cylindrical shape with partitions (blades).
  • the friction is smaller and there is less risk of cavitations.
  • Fixed pressure chamber (the body of the pump) can be with circular, rectangular or multi angular cross-section. In the pressure making pumps beside that draws the liquid from a certain depth, it should make a certain pressure for pushing the liquid to a certain height, a fixed chamber under pressure is necessarily to be there ( the housing of the pump filled with liquid under pressure).

Abstract

L'invention concerne une pompe à chambre rotative constituée d'un tuyau d'admission (3) qui tourne par rapport à son axe et par lequel le liquide d'un réservoir (1) entre dans la partie sous pression (4) de la pompe et grâce à l'influence de la force centrifuge dans la partie sous pression, une pression est produite dans les chambres rotatives (3) et le liquide, à cause de la différence de pression, sort des chambres rotatives par des ouvertures correspondantes (2) vers une chambre fixe (5). Ensuite, le liquide de la chambre fixe passe dans un tuyau de refoulement (6) hors de la pompe.
