Definitions

  • the present invention relates to an installation, of the type defined in claim 1 or 4.
  • the discharge pipe of the liquid jet ejector can lead into a liquid-gas separator comprising means connected to the suction pipe of the centrifugal pump and ensuring the return of all or part of the liquid collected in the separator , towards said centrifugal pump.
  • the gas (air), for example at 8,333.10 3 Pa, sucked in through line 9 is discharged through line 11 (for example at 28,867.10 3 Pa) and then sucked in, together with the entrained fraction of the water refrigeration of the liquid ring pump, by the water jet ejector 14 operating with pressurized water from the discharge pipe 17 of the centrifugal pump 13.
  • the gas (air) -water mixture from the ejector 14 is then discharged through line 18 into compartment 19 (at atmospheric pressure) where there is separation of air (gas) and water.
  • the latter mixed with the cooling water coming from the compartment 20 and optionally from a cooling water make-up pipe (not shown), is then sucked by the suction pipe 28 of the centrifugal pump 13.
  • the adjustment of the desired vacuum or the regulation of the power absorbed as a function of the volumetric capacity of the assembly can be carried out very simply using the manual or automatic valve 16 or alternatively by variation, manual or automatic. , of the diameter of the nozzle 15a of the water jet ejector 14.
