The entire rotating assembly shall be designed with sufficient rigidity for minimal shaft deflection at extreme pump operating conditions 整個旋轉總裝都應該具有足夠的硬度,即使在極端的泵運行環(huán)境下,所產生的軸偏差也是最小的。
The entire rotating assembly shall be designed with sufficient rigidity and balanced to provide for a maximum shaft deflection at the lower seal of 0 . 002 " under all operating points between plus or minus 40 % of the flow at best efficiency point ( bef ) on the pump ' s performance curve 整個旋轉總裝都應該具有足夠的硬度,在泵性能曲線最好性能的正負40 %的范圍內,在所有工作點,最大的軸偏差限制在0 . 002英寸內。
