【摘要】 本文根据质量矩定理对单缸滑阀真空泵的转子运动状况进行了分析,提出了转子惯性力完全动平衡的条件。实验表明,转子等运动部件在按此平衡条件作了部分改动后,泵的振动明显降低。文中还分析了三缸结构滑阀泵的“Triplex平衡技术”并认为这种平衡方式并没有使得转子惯性力完全平衡掉。更多还原

【Abstract】 In this paper ,the conditions tor the complete dynamic balance of rotor inertial forces in the rotan piston vacuum pump with single cylinder are detennined based on motion analysis.The experiment results show that the pump vibration can be depressed obviously by improving the rotor structure according to the balance conditions .It is proved that the rotor inertial forces can not be balanced completely even by means of the ’’Triplex balance technique" of the rotary piston pump with three cylinders.更多还原
