從后院的機(jī)器到大型卷板機(jī)設(shè)備,液壓設(shè)備有著功能卓越、運(yùn)用快捷的特色。在任何一個(gè)裝備上,都能夠看到液壓驅(qū)動(dòng)的設(shè)備,比方液壓卷板機(jī)、剪板機(jī)、折彎機(jī)、液壓機(jī)、沖剪機(jī)。甚至在修車場(chǎng),你能夠看到當(dāng)液壓設(shè)備把汽車吊起后，工人就能夠在車下作業(yè)了。許多自動(dòng)扶梯也是液壓驅(qū)動(dòng)的,甚至你車上的剎車體系也是液壓驅(qū)動(dòng)的!

液壓體系的基本原理十分簡略:經(jīng)過不行壓縮的液體,將作用于一點(diǎn)的力傳遞到另點(diǎn)。一般運(yùn)用某種油來作為液體介質(zhì)。在這一進(jìn)程中,力一般會(huì)增大。

The basic principle of a hydraulic system is very simple: the transfer of a force acting on one point to another through an uncompressible liquid. An oil is usually used as a liquid medium. In this process, the force generally increases.

液壓卷板機(jī)中液壓站的物理原理：

假設(shè)在兩個(gè)充溢油的、用一根輸油管銜接起來的汽缸里放入兩個(gè)合適的活塞,如果將其中一個(gè)活塞向下壓,壓力經(jīng)過輸油管中的油就會(huì)傳到第二個(gè)活塞。

Suppose two suitable pistons were placed in two cylinders filled with oil connected by an oil pipe. If one of the pistons were pressed down, the pressure would pass through the oil in the pipe to the second piston.

因?yàn)橛偷牟恍袎嚎s性,壓力傳導(dǎo)效率很高,簡直一切的作用力都被傳導(dǎo)到第二個(gè)活塞上。銜接兩個(gè)汽缸的管道能夠是任何長度、任何形狀,只需它能夠穿過兩個(gè)活塞中間的一切設(shè)備就行。管道能夠分叉,這樣如有必要,主汽缸能夠比輔汽缸有更大的驅(qū)動(dòng)力。

液壓體系設(shè)計(jì)的精妙之處在于,對(duì)體系進(jìn)行增壓(或減壓)的進(jìn)程十分簡略。你只需改動(dòng)一個(gè)活塞頭和一個(gè)汽缸的尺度就能夠了。液體介質(zhì)在體系中每個(gè)點(diǎn)上的壓力都相同。施加在較大活塞上的壓力作用面積較大,活塞遭到的向上的推動(dòng)力也較大。
