真空泵临界转速的快速计算

SPEEDY CALCULATION OF CRITICAL SPEED OF VACUUM PUMP

摘要: 设计真空泵时，泵的临界转速的计算是不可缺少的一环，否则泵在运行时就有可能产生剧烈的振动，使泵无法正常工作。试图简要地叙述有关临界转速的几个基本概念及有关影响的因素。介绍了简单可行的快速计算真空泵临界转速的方法。

Abstract: For a vacuum pump in design, the calculation of critical speed is necessary,otherwise it is possible for the pump to occur vibration so violent that the pump will be damaged.The calculation of cricical speed of a vacuum pump is p resented.
