油封式机械真空泵是科学试验和工业生产中，用以获得低真空的最基本的设备。由于其结构和工作原理的特点，振动和噪声是不可避免的。国外厂商很早以前就注意减振和降噪，所以其产品的噪声，一般比国产泵低１０分贝（Ａ）左右。国内用户近年来对减小振动和噪声要求强烈，为此，我所于一九八０年开始以应用较普遍的 Ｈ－１５０型滑阀式真空泵为对象开展机械泵的减振减噪声研究。在已经鉴定的样机上，取得了国内领先地位，但要把这一科研成果推广到生产当中去，还有一些工作要做。
Oil-sealed mechanical vacuum pump is a scientific experiment and industrial production, to obtain the most basic equipment of low vacuum. Due to its structure and working principle, vibration and noise are inevitable. Foreign manufacturers have long been aware of damping and noise reduction, so the noise of their products, generally lower than the domestic pump 10 dB (A) or so. Domestic users in recent years to reduce the vibration and noise requirements, therefore, I started in 1980 to apply the more common type of H-150 slide valve vacuum pump for mechanical vibration damping noise reduction studies. In the prototype has been identified, has made the leading position in the country, but to put this scientific research into the production of them, there are still some work to be done.
