HELIUM PUMPING WITH LIQUID RING VACUUM PUMP.

POMPAGE DE L'HELIUM PAR POMPE A VIDE A ANNEAU LIQUIDE.

Author(s) : MATHY C.

Summary

AT FIRST THE MAIN PRINCIPLES FOR OPERATION AND MANUFACTURING OF LIQUID RING PUMPS ARE REMEMBERED AND AN EXPERIMENT IS DESCRIBED WHICH ALLOWED TO ASSESS THE PERFORMANCE DATA OF SUCH PUMPS WHEN USED TO PUMP HELIUM GAS WITH OIL. ALTHOUGH THEY HAVE BEEN DESIGNED TO PUMP AIR WITH WATER THE ADAPTATION FOR HELIUM IS RATHER SIMPLE, THE INPUT POWER IS SLIGHTLY HIGHER IN THE SAME FLOW AND PRESSURE CONDITIONS, BUT THE LIMIT OF THE SUCTION PRESSURE IS LOWERED.
