| 摘要 | 1502451 Pressure exchangers BBC BROWN BOVERI & CO Ltd 21 May 1975 [11 July 1974] 21849/75 Heading F1N In a pressure exchanger having a rotor comprised of curved cell walls 1 each extending between a shroud at a location 3 and a hub at a location 4, the angle α between the locations 3 and 4 is less than 4 degrees and the angle # subtended at the centre of the rotor by the most angularly separated points on the median line 2 through the cell wall is less than 7 degrees. Each cell may be of sheet metal of uniform thickness or of cast metal having a thickness which decreases from one location, reaches a minimum, and then increases to the other location. The thickness of the cell wall at the shroud and hub locations 4, 3 are preferably twice and three times the minimum thickness, respectively. The preferred proportions of the radii R 1 -R 5 and r 1 -r 3 based on Ro = 100% are specified. The effects of differential thermal expansion and centrifugal forces is said to produce only slight stresses in the rotor. | ||||||
