Abstract

PURPOSE:To make the energy given to fluid by an impeller larger than the input given to the impeller, by having the vane angle of an impeller directed reversely against its rotation, and making 90 deg. angle to a radius direction, simultaneously with making up a passage area around the impeller's outlet as the same as others. CONSTITUTION:Intervals between an impeller inlet 1 and outlet 3 are generally radial or of a vane 2 being bent in the direction of rotation with the same radius ratio, and except the impeller inlet 1, the flow passage area around the impeller outlet 3 is roughly composed of the same way as other parts in order to generate a velocity head almost similar to that of other all radial-based impellers.
