Abstract：The adjusting mechanisms of blade angle in large pumps is introduced in this paper. The adjustments by hydraulic pressures and by machinery are analyzed and compared on structure, element, parts of system, control, installation, repairment and operation, automatic management, requirement from pumps, investment and reliability. Both of them are successful in large pump stations. But the machinary adjustment is simpler in structure and parts of system, easier in control and automatic management, more convenience in installation and repair, lower in requirements of pumps, fewer in investment, which will replace hydraulic pressure adjustment in the future.
