2、d on the evolution pedigree. 一、泵类机械演化谱系的梳理与编制能产生周期变化容腔的容积泵类机械可以设计成真空泵、内燃机、压气机、容积泵及气动、液动动力机械。这类容积泵类机械量大面广对人类经济活动有很大的影响,一百多年来,人们对它的发展和培育投入大量的人力和物力,曾经出现过上千种机械和方案,制成了不少样机,有些如三角活塞的Wankel内燃机与余摆线式真空泵、定片式真空泵和一些专利型的转子泵与压气机以及真空泵还在一定时期里成为流行商品。但它们的大多数在“物竟天择,适者生存”的法则下被淘汰或消失、成为供人们研究的“标本”和“化石”。然而依据认识论只有了解过去,才能理解现在
3、:只有把握过去和深刻理解现在,才能更好地预测与走向未来,它们是笔前人为后来的创新设计积累起来的财富。对此人们往往还没有充分的认识。在机械行业里,对于那些历史的、过去的、陈旧的,NL系列污水泥浆泵 大型泥浆泵大型泥浆泵his, theauthor put forward the venation of screw evolution, precession evolutionand scroll evolution, and draw up the evolution pedigree.
