based on the characteristics of pump assembly, the influences of hydraulic resistance of trash rack and feculence on pump unit operation are investigated.
根据水泵装置特性研究了拦污栅及其污物阻水对泵机组运行的影响。
the trash rack contains trash rack bar and trash rack groove; the bar is composed with grid surface and support frame;
拦污栅包括拦污栅栅叶和拦污栅槽两部分,栅叶是由栅面和支承框架组成;
trash rack of pump station is indispensable for stability and safety of pump assembly though it is an auxiliary facilities.
泵站拦污栅虽然是辅助设施,但对保证水泵机组安全、稳定必不可少。
the plane gate and the trash rack for the national key project yantan hydropower station had the honor to receive the title of guangxi quality product.
为国家重点工程巖滩水电站制造的平面闸门及拦污栅曾荣获广西优质产品称号;
the connections between trash rack and hoist as well as between service gate and hoist are achieved by hoisting chain that is apt to place and is time saving without tearing down pull rod.
