机械增压泵的传统的直联传动方式存在一些缺点。为了克服这些缺点,出现了液力传动。本文综述了直联传动和液力传动,并且对它们的特性进行了比较。同时,讨论了该泵人工合成润滑剂的使用和对泵性能的影响。当采用直联传动或液力传动以及抽吸腐蚀性或危险性气体时,机械增压泵的主 Mechanical booster pump of the traditional direct drive there are some shortcomings. In order to overcome these shortcomings, there has been a hydraulic drive. This article reviews both direct drive and hydraulic drive, and compares their characteristics. At the same time, the use of the pump synthetic lubricant and the influence on the pump performance are discussed. When using direct drive or hydraulic drive as well as pumping corrosive or dangerous gases, the main mechanical booster pump
