Definitions

  • Vacuum pump unit arranged on a portable support frame
  • the invention relates to a vacuum pump unit arranged on a portable support frame.
  • a vacuum pump unit which is arranged on a mobile support frame.
  • the pump unit consists of a liquid ring pump which is coaxially coupled to a drive motor by means of a shaft coupling.
  • the shaft coupling is arranged outside the housing of the drive motor between the latter and the liquid ring pump.
  • the Abscheide ⁇ container for the operating fluid of the pump is located parallel to the pump and the drive motor.
  • the invention is based, with reduced
  • the vacuum pump unit according to the invention is distinguished by a low power requirement in relation to the delivery quantity. This is achieved by arranging a dry-running vacuum pump, which is connected upstream of the liquid ring pump with respect to the direction of flow of the medium to be pumped.
  • a gas ring vacuum pump can advantageously be provided as the dry-running vacuum pump.
  • the coupling of the gas ring vacuum pump with its own drive motor enables optimal control of this pump in cooperation with the downstream liquid ring pump.
  • the material expenditure for the unit is reduced. Space is also saved.
  • gas ring vacuum pump is driven via a belt pulley arranged on the outer circumference of the fan for the air cooler, then separate parts and thus also the costs for this drive resulting from its assembly are saved.
  • the liquid ring pump 2 designates a portable support frame on which a liquid ring pump 2, its drive motor 3 as well as a separating container 4 and an air cooler 5 for the operating liquid of the liquid ring pump 2 are arranged.
  • the liquid ring pump 2 is mounted on one end face of the drive motor 3 with its housing directly on the housing of the drive motor 3.
  • the air cooler 5 is mounted on the side of the drive motor 3 opposite the liquid ring pump 2 with an axial spacing from it on the support frame 1.
  • a fan 7 required for this can be arranged on the shaft end of the drive motor 3 in the intermediate space 6 between the drive motor 3 and the air cooler 5.
  • the unit shown also has a Gasri ⁇ gvakuumpu pe 8, which is connected upstream of the liquid ring pump 2 with respect to the flow direction of the medium to be pumped.
  • the gas ring vacuum pump 8 is assigned its own drive motor 9, which drives it via a belt drive 10.
  • the gas ring vacuum pump 8 and its drive motor 9 are arranged on the support frame 1 in a plane above the liquid ring pump 2 and its drive motor 3. Thus, only short lengths are required for the necessary mechanical pipe connections between the upstream gas ring vacuum pump 8 and the liquid ring pump 2.
  • the gas ring vacuum pump 8 and the liquid ring pump 2 each with its own drive motor 3 or 9 offers the possibility of controlling the speed of the pumps so that an optimal adaptation of their delivery rates is achieved.
  • optimal operation of the gas ring vacuum pump 8 can be ensured by regulating the speed of its drive motor 9 such that the current consumption remains constant over the entire speed range.
  • the gas ring vacuum pump 8 can also be driven by the drive motor 3 of the liquid ring pump 2 via a V-belt. A separate drive of the motor for the gas ring vacuum pump 8 is thus saved.
  • the fan 7 can be provided on its outer circumference with a corresponding V-belt pulley, so that no additional space is required for a separate drive pulley.
  • the adjustment of the delivery rate of the gas ring vacuum pump 8 to the delivery rate of the liquid ring pump 2, which is necessary above all when starting up the unit in the low vacuum phase, can be achieved by appropriate circuitry with bypass and / or throttle valves.

Abstract

Un ensemble pompe à vide agencé sur un châssis transportable (1) comprend au moins une pompe annulaire (2) de liquide couplée à l'arbre d'un moteur d'entraînement (3), un refroidisseur (5) et un récipient séparateur (4) du liquide fonctionnel de la pompe annulaire de liquide (2) qui circule en circuit fermé. Le refroidisseur (5) formé par un refroidisseur à l'air est agencé axialement devant la face frontale du moteur d'entraînement (3) opposée à la pompe annulaire de liquide (2), et le ventilateur du refroidisseur à l'air (5) est agencé directement à l'autre extrémité de l'arbre du moteur. Afin de réduire le volume, les besoins en énergie et en matériaux, et de simplifier le montage, la pompe annulaire de liquide (2) est montée sur le carter du moteur d'entraînement (3) et sa roue mobile est directement agencée sur une extrémité de l'arbre du moteur. En outre, une pompe à vide (8) fonctionnant à sec est montée sur le châssis (1) en amont de la pompe annulaire de liquide (2), par rapport au sens d'écoulement du milieu à refouler.
