一、前言 滑阀式真空泵是一种偏心运动机械,它的工作过程,是由偏心轮带动滑阀沿着泵缸壁作圆周运动,而滑阀杆在滑阀导轨中作上下往复摆动,当偏心轮转过上死点后,滑阀将泵缸分隔成吸气和排气两个胶,它们的容积周期地扩大和缩小,达到抽排气之目的。 由于滑阀泵是一种偏心运动机械 First, the preamble Sliding valve vacuum pump is a kind of eccentric movement of machinery, its work process is driven by the eccentric slide along the pump cylinder wall for circular motion, and the slide valve spool in the slide up and down swing back and forth when Eccentric wheel after turning on the top dead center, the spool valve will pump cylinder is divided into two kinds of suction and exhaust glue, their capacity to expand and shrink cycle to achieve the purpose of pumping exhaust. As the spool valve pump is a kind of eccentric movement machinery
