A11VO130LRDU2/10L-NZD12N00VH-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。

因为玻璃失去了其抗压。加热或冷却钢或玻璃，将改变玻璃的抗压。如果温度突变，玻璃里的抗压也将突变，引起玻璃爆裂。这就是所知的热冲击。因为玻璃的强度随着残余的抗压减少而降低。很明显，在较高的温度下，热冲击将更普遍。这时，搪玻璃的抗压就较低。结果，不同的温度所引起的热冲击将随着搪玻璃温度温度的增加而减少。图6显示了这个特点，分别是热冲击大和小的曲线的坡度。在环境温度下做的测试表明，玻璃应该能承受的，不会裂开的大允许温差大约为2摄氏度。
