1、水轮机的比速和转速(1)比速 N_s=N×(P~(1/2)H~(5/4))(m·kW)(2)转速 N=N_S×(H~(5/4)/P~(1/2)((rpm)式中:Ns为比速(m·kW);N为转速(rpm);P为在有效落差H时,最大输出功率(kW)(对应于冲击式水轮机的一个喷咀;反击式水轮机的一个叶轮).
1. Ratio and speed of turbine (1) Specific speed N_s = N × (P ~ (1/2) H ~ (5/4)) (m · kW) (2) Rotation speed N = N_S × (H ~ (Rpm) where Ns is the specific speed (m · kW); N is the speed (rpm); P is the maximum output power (kW) at the effective drop H; (A nozzle corresponding to an impulse turbine; an impeller of an impact turbine).
