RADIAL COMPRESSOR HAVING A RADIAL SLOT BETWEEN THE IMPELLER WHEEL WHEEL DISK (OR IMPELLER WHEEL COVER DISK) AND HOUSING

摘要

Radial compressor (1) having a drivable impeller wheel (3) accommodated in a housing (2), which drivable impeller wheel has a wheel disk (4), a cover disk (5) and blades arranged therebetween, wherein the impeller wheel (3) and a transition area (12, 3) is configured between the wheel side space (8, 9) and the impeller outlet (10) such that the following inequality is satisfied: s/b≤Fd, wherein s is a mean distance in the radial direction between the outer edge of the wheel disk (4) or of the cover disk (5) and the housing (2), b is the axial width of the wheel disk (4) and/or the cover disk (5), F is an empirical factor and d the clear axial distance between the wheel disk (4) and the cover disk (5).
