摘要
“高速油液冲击”是滑阀真空泵冲击噪声的主要激励源 ,通过试验发现了这一冲击的前移现象 ,并进一步分析了高速油液冲击和其他三种冲击的形式 ,为降低滑阀真空泵噪声提供了可靠的依据。
High pressure oil shock” has been found to be the major source of shock noises in the rotary piston vacuum pumps.Recently,we found that the oil shock may shift forward.Here,the high pressure oil shock and the formation mechanism of three other types of shock were analyzed so as to reduce the vacuum pump noises.
