Definitions

  • the invention relates to a two-spindle screw pump in a single-flow design, with an external bearing of the two screw spindles, a pump housing enclosing at least the two screw spindles and thereby forming the delivery chambers required for the pumping process, an inlet-side connection leading into a suction chamber for the delivery medium to be drawn in, and an outlet , with a pressure chamber connected connection for a pressure delivery line for the medium to be discharged.
  • FIG. 1 A previously known embodiment of this type is shown in FIG. 1 as prior art. Due to its self-priming and low-shear conveying characteristics, this design is becoming increasingly popular in conveying processes with valuable and / or shear-sensitive conveying products such as food or chemicals. In contrast to the widespread double-flow design, the single-flow design enables the pump's product space to be opened quickly, easily and completely for cleaning and disinfection purposes.
  • the product space is essentially formed by the pump housing, which has various tasks: Enclosing the screw spindles to form the delivery chambers required for the pumping process;
  • polishing processes on conventional cast metal housings are generally questionable.
  • connection piece shapes are common, which also vary regionally (e.g. due to local regulations). Twenty different connection sockets for a pump type are not uncommon depending on the industry and regional use. With one-piece cast metal housings, the storage costs increase enormously due to the variety of variants.
  • the object of the invention is to develop a more economical design for the two-spindle screw pump described at the outset, which also enables testable and documentable cleaning or sterilization processes and an increase in the wear resistance of the pump housing in the area surrounding the screw spindles.
  • connection module an exchangeable inlet or outlet connection housing module
  • conveyor housing module which forms a parting line and which has its inner circumferential surface delimits the delivery chambers on the outside
  • connection module running perpendicular to the spindle axes through the suction chamber or pressure chamber cross section.
  • a three-part pump housing is particularly advantageous because it creates the best conditions for eliminating the above-mentioned problems and thus for solving the above-mentioned task.
  • the conveyor housing module can thus consist of a solid metal blank with subsequent machining, or it can be welded together as a welded part from commercially available semi-finished products, such as pipe sections and plates, and then machined.
  • the housing area surrounding the conveyor screws can be optimally adapted to the requirements of the conveyor process.
  • the inner surface of this housing area can be polished using suitable methods and the surface quality can be properly checked.
  • Optimized wear protection layers can be reliably implemented, e.g. through structural changes, diffusion processes, applied wear protection layers or inserts made of solid industrial ceramics.
  • Metal investment casting or sheet metal formed parts are suitable for the inlet and outlet connection housing modules, since both the surface requirements in the conveying process and the strength requirements can be met by introducing force via pipes in the conveyor system.
  • connection modules for integrating the screw pump into a conveyor system
  • Connection pieces can either be made using the primary molding process (investment casting) can be cast on directly or subsequently welded on using a suitable process. For this purpose, it is expedient if a suitable preparation for the subsequent welding of a connecting piece is implemented in the inlet and / or outlet connection housing module.
  • FIG. 2 in a representation according to Figure 1, a two-spindle screw pump according to the invention.
  • each is a two-spindle screw pump with external bearing in a single-flow design.
  • the pump housing 3 has an inlet-side connection 6 leading into a suction chamber 5 for the delivery medium to be sucked in, symbolized by an arrow 7, and furthermore has a connection 9 for a connection to a pressure chamber 8 Pressure delivery line for the delivery medium to be discharged, symbolized by an arrow 10.
  • the pump housing 3 enclosing the two screw spindles 1, 2 forms the delivery chambers 11 required for the pumping process, which, when the screw spindles 1, 2 rotate, conveys the pumped medium from the suction chamber 5 into the pressure chamber 8. Since there is only this one flow direction for the pumped medium, one speaks of a single-flow design.
  • FIG. 2 which shows an embodiment of the invention, for example, the components that correspond to FIG. 1 are provided with the same reference numerals. So it is also a two-spindle screw pump with external bearings in a single-flow design;
  • the pump housing 3 which is constructed in three parts, is designed differently. That part of the pump housing which directly surrounds the screw spindles 1, 2 and thereby forms the delivery chambers 11 required for the pumping process and delimits them radially on the outside with its inner circumferential surface 1 2a is designed as a delivery housing module 122, on the one of which (in FIG left) end face an interchangeable inlet connection housing module 13 and on the other (right in FIG. 2) end face an interchangeable outlet
  • Connection housing module 14 are flanged.
  • the joints 1 5, 1 6 formed on each of the two end faces of the conveyor housing module 1 2 with a connection module 1 3 or 1 4 each run perpendicular to the spindle axes 1 7, 18 through the suction chamber 5 or pressure chamber 8 cross section.
  • Each of the two connection modules 13, 14 is provided with a connection piece 19, 20, which are used to integrate the screw pump into a conveyor system (not shown in more detail) and either cast directly in the master molding process (investment casting) or subsequently welded on using a suitable process.

Abstract

L'invention concerne une pompe à double broche hélicoïdale à un seul flux, qui comprend un palier extérieur (4) des deux broches hélicoïdales (1, 2), un carter de pompe (3) entourant au moins les deux broches hélicoïdales (1, 2) et formant ainsi les chambres de refoulement (11) nécessaires au processus de pompage, un raccord (6) côté entrée, conduisant dans une chambre d'aspiration (5) pour le liquide refoulé à aspirer (flèche 7), ainsi qu'un raccord (9) côté sortie, relié à une chambre de pression (8), pour une conduite de refoulement sous pression pour le liquide refoulé à évacuer (flèche 10). Selon l'invention, au moins un des deux raccords (6, 9) fait partie d'un module carter de raccordement d'entrée ou de sortie remplaçable (13 ou 14) ou module de raccordement qui est fixé par bride, avec formation d'une fente de séparation (15, 16), sur un module carter de refoulement (12) limitant à l'extérieur les chambres de refoulement (11) avec sa surface d'enveloppe intérieure (12a). Les fentes de séparation (15, 16) entre le module carter de refoulement (12) et le module de raccordement (13, 14) s'étendent perpendiculairement aux axes (17, 18) des broches à travers la section de la chambre d'aspiration (5) et de la chambre de pression (8).
