A11VO95LG1D/10L-NZD12N00-S柱塞液压泵河北唐山柱塞泵的工作原理
柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动,使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点,被广泛应用于高压、大流量和流量需要调节的场合,诸如液压机、工程机械和船舶中。
柱塞泵是往复泵的一种,属于体积泵,其柱塞靠泵轴的偏心转动驱动,往复运动,其吸入和排出阀都是单向阀。当柱塞外拉时,工作室内压力降低,出口阀关闭,低于进口压力时,进口阀打开,液体进入;柱塞内推时,工作室压力升高,进口阀关闭,高于出口压力时,出口阀打开,液体排出。当传动轴带动缸体旋转时,斜盘将柱塞从缸体中拉出或推回,完成吸排油。

分子泵:涡轮分子泵是靠高速转子携代气体分子获得高真空的一种机械式真空泵,工作压力范围为1-1~1-8pa,它具有抽速较大,抽速范围很宽的特点,分子泵适用于要求清洁的高真空和高真空的设备上使用,但它不能直接对大气排气,需要配置前级泵、由于分子泵属于分子动能泵在大气压下启动分子泵、分子密度过大、泵工作要发热损坏。空检漏真空检漏是真空获得保证,它是检测真空系统的漏气部位及其大小的过程。漏气是影响真空获得和真空维持的主要因素。
