The biaxial contrarotating centrifugal fluid pressure booster of the present invention relates to an inprovement in a centrifugal turbo-blower, a compressor or a turbine pump. The booster includes two large and small vane wheels. The larger vane wheel (second vane wheel) covers the smaller one (first vane wheel), rotates in the direction opposite to the first vane wheel and functions as a rotary diffuser. The second vane wheel as the rotary diffuser decreases extremely efficiently the high speed of a fluid discharged from the first vane wheel to nearly zero, or deflects the direction of the discharged fluid, reduces the frictional loss of the fluid inside a casing and brings about as a whole a large pressure rise of the fluid with a high efficiency. |
