摘要： To provide a can manufacturing pump impeller in which a stress of a base portion of a blade is prevented from increasing while improving the strength of a joint portion of a hub and a boss. In order to reinforce a joint portion of a hub and a boss, a plate is jointed to the inside of an impeller. In order not to overlap a base portion of a blade and the plate with each other on the hub, an opening portion is provided in the plate around the base portion of the blade on the hub. As a shape of the opening portion, a semicircular shape, a semielliptical shape, a rectangular shape, or a trapezoidal shape can be selected. Further, as a plate shape, a flat plate structure, a shell structure, or a curved structure can be selected.
摘要翻译：为了提供能够防止叶片的基部的应力的提高的罐式制造泵叶轮，同时提高轮毂和轮毂的接合部的强度。为了加强轮毂和凸台的接合部分，将板连接到叶轮的内部。为了不使轮毂上的叶片的基部和板彼此重叠，在板上围绕叶片的基部的毂上设置有开口部。作为开口部的形状，可以选择半圆形，半椭圆形，矩形或梯形形状。此外，作为板状，可以选择平板结构，壳结构或弯曲结构。

摘要： A centrifugal turbomachinery in accordance with the present invention can lower a fluid loss in a return flow path. In the centrifugal turbomachinery, a plurality of centrifugal impellers is attached to a rotating shaft, and the centrifugal turbomachinery is provided with a diffuser having a plurality of blades introducing a fluid boosted by a front stage impeller to a rear stage impeller, and a return flow path means. The return flow path means has a side plate arranged in a back surface side of the front stage impeller, a plate opposing the side plate and arranged in a front surface side of the rear stage impeller, and a plurality of blades arranged between the side plate and the plate so as to be spaced in a peripheral direction. A maximum diameter portion of the side plate is changed in the peripheral direction.
