| 摘 要： | 介绍了大型立式轴流泵的叶片调节方式，对油压调节方式和机械调节方式从结构、工作原理、系统构成、控制方式、安装、检修与运行、自动化管理、泵的构造要求、投资、运行可靠性等方面进行分析比较，认为两种调节方式在大型泵站的运用都是成功的，但机械调节方式结构和系统构成更简单，控制方式和自动化管理更容易，安装、检修方便，对泵的构造要求不高，投资也少，机械式调节有替代液压式全调节的趋向。

| 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. |
