機械外文翻譯---液壓機-液壓系統(tǒng)(完整版)
【正文】 制壓力與距離的關(guān)系。 當水慢慢地被灌入液 壓機圓筒（液壓缸）的時候 ，活塞和其負載被向上推，直到某個位置（液壓缸的低部）停下來。 舉例來說，如果規(guī)模較小的活塞 的 面積 為 2 平方英寸 ，并在其上施加一百磅的力， 那么， 施加到 一個面積 為 50 平方英寸 面積的活塞上的力將是 2500 磅 。液壓升降機也遵循帕斯卡法 則 。液壓千斤頂 一般被用于施加大壓力或頂起重物的場合，它 也 遵循 帕斯卡 定 律 。這個裝置包括兩個液壓缸，每個里面都有充滿的液體和一個合適的活塞，兩個缸之間通過充滿液體的管道連接。 最高端與最低端之間的高度差被稱為勢能 . 每一磅水所做的功與勢能成比例，通過這種辦法，水能的形成可以來源于許多自然資源，諸如 瀑布和大壩。液壓千斤頂被用來校平鐵塔與校準鐵制橫梁，此時它的精確度可以達到 1 毫米。s law, is used to exert large forces or to lift heavy loads. Like the hydraulic press it consists essentially of two differentsized pistons contained in cylinders that are connected by a pipe. When the smaller piston is moved back and forth by a handle connected to it, it pumps a liquid into the cylinder of the larger piston, forcing the larger piston to move. In this way a weak force applied to the smaller piston can raise a heavy load on the larger one. The hydraulic elevator is also an application of Pascal39。s. Hydraulic jacks were used to level the tower and align the metal girders to an accuracy of 1 millimeter。 Today most hydraulic systems utilize oil rather than water but the principle is the same. You can press a liquid, and a force that is applied at one point is transmitted to another point by that inpressible fluid. Because of its liquid nature, hydraulic systems can transmit force through pipes of any shape and length, so the force can be applied at one central point and transmitted efficiently to another point or to multiple points far away. Think about the master cylinder in you car39。s law. Totally understanding hydraulics is very plicated, but a basic understanding of the principle of how it works is actually very straightforward. 英文翻譯 液壓機 來源： 哥倫比亞百科全書 ,第六版 日期 : 2021. 液壓機的能量來源于水或其它液體的壓力或動力。今天液壓系統(tǒng)使用油而不是水，但工作原理還是一樣的。沒有一個
