A11VO190LRU1/11R-NPD12N00H-S柱塞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。

作者:装车开始后,先开装车线上的手阀d,待压力表f示值相等时,再开气相返回线上的手阀g,而我们原来装车是,开始就将手阀g全部打开,这时装车线上的压力比罐车内的压力高许多,这样就很容易将罐车内残存的一部分丙烯冲回到丙烯罐内,从而产生计量误差。经过改进操作方法,该系统工作正常,达到了准确定量装车,提高工作效率的目的。在22年新装置投运过程中,笔者结了一些靶式流量计的使用经验。靶式流量计按照技术条件安装完毕后(靶式流量计出厂时已按设计要求好),按操作步骤投运,发现少数仪表显示误差较大,有的报警显示满量程。
