A11VO260LRS/11R-NPD12N00斜轴液压泵河北秦皇岛柱塞泵的工作原理
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。

在液体状态中,氟化物将严重浸蚀搪玻璃,产生粗糙的表面,完全失去光滑。在蒸汽状态形成含有四氟化硅和水蒸气的状态形成含有四氟化硅和水态中,由于腐蚀更集中,爆瓷和针孔将很明显,但却大大地减少了光滑程度。不论在那一种情况下,都取决于其浓度。这样,搪玻璃容器在相对短的时期内就变得没有用了。防止氟化物腐蚀要求持续的防范。含有氟化物杂质的反应物必须进行分析,以在使用前决定氟化物的水平。特别是工业生产中的磷酸以及盐类经常是被氟化物污染的,正如其他的矿物酸一样。
