中文摘要:
      典型的容积泵有柱塞泵、齿轮泵和叶片泵等,综述了柱塞泵的机械噪声和流体噪声、密封及泄漏问题、摩擦副的润滑问题,并阐述了问题产生的机理和研究方法;综述齿轮泵和叶片泵的困油、流量脉动和噪声等问题及解决方法。经过国内、外科研院所多年的技术攻关,容积泵在这些方面有很大改善,但是排量体积比小、脉动率大等问题需要继续研究解决,同时也有必要提出新型容积泵。
英文摘要:
      The typical displacement pumps are plunger pumps, gear pumps and vane pumps. The first,this paper summarized the problems of plunger pumps which are mechanical noise and fluid noise, lubrication problems of the friction pair and so on. Then it expounded the mechanism and research methods of the problem. Then it summarized the problems and solutions of the gear pumps and the vane pumps which are about the trapped oil, flow pulsation and noise. Do a lot of researches in domestic and foreign Institute, the displacement pumps have been greatly improved in these problems. But the problems such as small volume ratio and high pulsation rate need to be studied and solved. So it is necessary to put forward a new type of displacement pump.
