Abstract

PURPOSE: To prevent strain in the horizontal direction of a casing in such a way that high temperature gas rising part and low temperature dropping part are distributed in spiral shape, thermal expansion in the vertical direction is made even in circular direction.
CONSTITUTION: Two flow passages in spontaneous convection are provided by making heat shielding plate 40 into two sheets. Then, by the difference of initial condition, etc. of the flowing passages, cover gas rises through the passage on one side, it drops through the passage on the other side. Since rising gas is higher in the temperature than dropping gas, though it gives a pump casing unequal thermal expansion, by reason of spiraling both rising and dropping streams, even if inequality in temperature is yielded locally, it precludes the pump casing from concentration of one-sided elongation. Such as this, since the high temperature gas rising part and low temperature dropping part distribute spirally, the total of thermal expansion in the vertical direction is made uniformly in the circular direction, there is an effect of preventing strain to cause displacement of the pump casing in the horizontal direction.
