Rexroth力士乐柱塞泵

供应Rexroth力士乐柱塞泵A10VSO100DR/31R-PPA12N00由液体静压力基本方程可知:


静止液体内任一点处的压力由两部分组成，一部分是液面上的压力p0，另一部分是ρg与该点离液面深度h的乘积。当液面上只受大气压力pa作用时，点A处的静压力则为 p=pa+ρgh。
同一容器中同一液体内的静压力随液体深度h的增加而线性地增加。
连通器内同一液体中深度h相同的各点压力都相等。由压力相等的组成的面称为等压面。在重力作用下静止液体中的等压面是一个水平面。

根据静压力基本方程(p=p0+ρgh),盛放在密闭容器内的液体，其外加压力p0发生变化时，只要液体仍保持其原来的静止状态不变，液体中任一点的压力均将发生同样大小的变化。


这就是说，在密闭容器内，施加于静止液体上的压力将以等值同时传到各点。这就是静压传递原理或称帕斯卡原理。


帕斯卡原理应用一个密闭容器，按帕斯卡原理，液压缸内压力到处相等，p1≈p2，于是
                 F2＝F1A2/A1
    如果垂直液压缸的活塞上没有负载，则当略去活塞重量及其它阻力时，不论怎样推动水平液压缸的活塞，也不能在液体中形成压力，这说明液压系统中的压力是由外界负载决定的。
