| description | The invention relates to a water supply system of a 660 MW-grade steam turbine and a water pump steam turbine final-stage moving blade thereof. The steam turbine is only provided with one 100% water supply pump steam turbine; an effective height of a blade is 530 mm; an absolute value of a blade height H is monotonically increased from 0.0 to 1.0; correspondingly, an installation angle c1 is monotonically decreased from 83.03 degrees to 16.55 degrees; a change rule of an area A from a root section to a top section is A not smaller than 1.0 and not larger than 8.935; a change rule of an axial width Xa from the root section to the top section is Xa not smaller than 1.0 and not larger than 5.602; a change rule of a chord length b1 from the root section to the top section is b1 not smaller than 1.0 and not larger than 1.63; and a change rule of a maximum thickness w1 from the root section to the top section is w1 not smaller than 1.0 and not larger than 3.593. The water supply system is suitable for a 100% volume |
