Definitions

  • the invention relates to a simply designed roller pump with permanent, economical and reliable space displacement, the liquid being transported by concentric guide shoulders formed in the closed space, the housing and the cover on a roller track on two ends and by means of an actuating rotor part which is eccentrically arranged compared to the housing .
  • the roller pump according to the invention can be used advantageously instead of any volumetric pump.
  • Some of the pumps selected from the extraordinary majority of space displacement pumps such as valve piston pumps, space displacement pumps without valve, within which gear pumps with external or external and internal toothing, trochoidal pumps, Galloway pumps, pumps with rotary drum shut-off valve, pumps with rotary slide valve, pumps with radial pistons, eccentric pumps with rotating vanes, screw pumps, peristaltic pumps, etc., / Füzi, Olivér: Fluid mechanical machines, technical lexicon, volume I / have the common characteristic that their energy demands are relatively large, their structure and their assemblability complicated, their wear and tear during permanent operation significant , their training, commissioning, maintenance, renewal are expensive and are not capable of transporting liquids of any kind and tightness.
  • the aim of the invention is to eliminate the disadvantages of the known space displacement pumps and to create a roller pump, which by its one simple construction, by means of the creation of a large vacuum and high pressures an effective pumping, a safe, permanent, noiseless operation with liquids of all kinds is guaranteed.
  • the objective is achieved in that with the use of plastic rollers, which are appropriately guided to move the liquid on a roller track, the energy demand of the pump is reduced, the transport of dense, sticky materials or materials mixed with a liquid of smaller grain size means that the suction is conveyed from a large vacuum Transport of warm liquids, food industry products, pastes etc. are guaranteed.
  • roller pump according to the invention is less sensitive to the lack of liquid that occurs during pumping, its wear after long operation is insignificant, is not dynamic, has no maintenance claim, can be quickly and quickly reassembled after long-term operation and at low cost by changing the roller and seal , their manufacture is simple, their lifespan is long.
  • the invention is based on the recognition that when a rotor part is arranged in a concentric pump housing on an axis which is introduced eccentrically in comparison with its axis, said rotor part zeros the suction pressure openings of the housing in the lateral surface separating barrier in its center line has minimal gaps, for example of 0.1 mm and this rotor part has grooves, has openings per groove necessary for additional suction removal of the liquid, and the inner shoulder jacket surfaces of the locking barriers between the grooves of the side surfaces with the shoulder jackets of the Cover and the housing base are adapted to fit, which are arranged in this rotor part and with one end in the forced path between the outer jacket of the concentric shoulder of the housing bottom, suitably made of plastic rollers - which have their other ends on the outer jacket of the pump housing cover and the formed therein adjust concentric shoulder as a constraint path - during the rotation of the rotor part, widening and narrowing spaces with each other in the space delimited by the inner jacket of the pump housing and the jacket of the
  • a rotor part 2 is arranged eccentrically in the pump housing 1 so that it can be rotated by the axis 4, the rollers 3 being designed to be rotatable in the grooves of the rotor part 2.
  • the rollers 3 are expediently made of plastic, and the dimension change caused by the possible heat effect and moisture was also taken into account in the dimension determination.
  • the roller 3 is in the constraint path between the jacket of the housing 1, the jacket of the shoulder 10 and the shoulder jacket 11 of the lid 5 in addition to securing a small gap of, for example, 0.1 mm and at its ends is between the plane of the housing 1 and a minimal gap is also formed in the bottom of the cover 5.
  • a column is also on the connections between the jacket of the housing 1 and the lock 6 of the outer jacket of the Ro gate part 2, between the shoulder jackets 10 and 11 in point A of the inner jackets of the end locks 12, between the grooves of the rotor part 2 and the rollers 3, between the levels associated with the housing 1, the shoulders 10, 11 of the cover and the levels of the attached Rotor part 2 formed.
  • the suction pressure openings 7, 8 are separated from one another at the lock 6 on the inner lateral surface of the housing 1 by the edges of the jacket of the rotor part and the jacket of the roller 3.
  • the openings of the suction pressure ports 7, 8 are formed in the housing 1 in such a way that the space between the rollers 3 with the different pressure spaces can never be opened together.
  • the opening 9 extending from the surface below the roller 3 groove of the rotor part 2 opens in the jacket.
  • the horizontal axis of the rotor part 2 is arranged at the point of greatest eccentricity within the pointed edges of the groove in the direction of the axis 4.
  • the connection of the suction pressure chambers 7, 8 is prevented by the end locks 12 on the end faces of the rotor part 2 between the two rollers 3.
  • the housing 1 contains the sealing elements T of the axis 4, which are expediently mountable by the rotor part.
  • roller pump according to the invention works as follows:
  • the liquid arriving through the suction port 7 speed fills the space between the inner surface of the housing 1, the outer surface of the rotor part 2, the rollers 3 and the lock 6, as a suction space.
  • This space is separated from the pressure space by the lock 6, the outer jacket of the rotor part 2, the end locks 12 and the rollers 3.
  • the rotor part 2 moves the rollers 3 arranged in its grooves at their two ends on the shoulders 10 and 11 and on the inner jacket of the housing 1 in concentric circles, and thus a widening space is created between the rollers 3.
  • the lateral surfaces of the housing 1 and the rotor part 2 bring about a pressure space with a narrowing volume between the rollers 3 and the lock 6. Meanwhile, due to the gradual decrease in the Groove space below the roller 3 of the rotor part 2 through the opening 9 into the pressure chamber, partially into the spaces delimited by the points ABC on the pressure chamber side.
  • the rollers 3 arranged in the rotor part 2 also perform rotary movements about their own axes via their circular movement in the housing 1 and on the positive path between the shoulders 10, 11. The direction of rotation of the pump and the direction of liquid transport can be changed.
  • roller pump according to the invention is suitable for the transport of liquids, pastes, etc. of various tightness, quality and temperature. If the roller pump according to the invention does not receive any liquid during operation, immediate adjustment is not necessary, and there is no seizure of the components.
