A basic diagram of the refrigeration system, in which liquid hefium is circulated by means of a jet pump, is described. The equations have been derived to design jet devices which operate with liquid helium. In the experimental setup with a jet pump the flow rate of liquid was 5 to 10 times larger
A centrifugal pump used for c~rculatmg hqutd hehum through a large superconducting magnet was tested The performance of the pump was measured during a magnet coohng test The pump operated well wtth atyptcal capacity of 400 dm 3 h -~ (Ap = 0 3 kg cm-2) at 20000 rpm An analys~s of the test results ~s
The operation of a jet pump using a helium, two-phase mixture has been studied. It is shown that for the two-phase region, the relations obtained from the momentum equation are valid only up to the onset of limiting modes, ie until the stream velocity achieves the velocity of sound in any section of
