Abstract
PURPOSE: To improve the performance of a diffuser by forming the conical taper part at the inlet part of a diffuser, narrowing the width of a flow passage and installing a plurality of guide vanes at the tapered part and forming uniform the distribution of the flow at the inlet part of the diffuser.
CONSTITUTION: At the inlet part of a diffuser plate 8, the conical taper part 11 is formed, narrowing the width of a flow passage narrower than the exit width of a impeller and a plurality of short guide vanes 12 nearly parallel to the direction of main flow in the diffuser are arranged in the tapered part. The height of the guide vane 12 is the same to the height of the wall surface of the diffuser in the rear half part or within the range not exceeding the height described before. Through the action of this taper part 11, the flow at the exit of the impeller is accelerated, and the boundary layer becomes thinner, and exfoliation is prevented, and the flow in the vicinity of the wall surface is directed in the radial direction, and the flow at the inlet part of the diffuser is made uniform.
