A11VLO260LRDCS/11R-NZD12K79油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。

下面就高低温湿热试验箱为例，谈一谈高低温湿热试验箱的构造及一些常见故障和排除方法。、常见高低温湿热试验箱的构造试验人员除正确按操作规程操作，还应该对其结构有所了解。高低温湿热试验箱由箱体、风循环系统、制冷系统、加温系统和控湿系统组成。风循环系统一般采用可调节送风方向的结构；加湿系统有采用锅炉加湿的和表面蒸发二种；降温、去湿系统采用空调工况制冷结构；加热系统采用电热鳍片加热和电炉丝直接加热二种结构；温湿度测试方法采用干湿球测试方法，也有用湿度传感器直接测量方法；控制和显示操作界面采用温湿度分开独立和温湿度组合控制器等方式。
