機(jī)械專業(yè)畢業(yè)設(shè)計外文翻譯--什么是液壓-液壓系統(tǒng)-免費(fèi)閱讀
【正文】 在 1955 年前后 , 日本迅速發(fā)展液壓傳動 ,1956 年成立了 “液壓工業(yè)會 ”。 1905年將工作介質(zhì)水改為油 ,又進(jìn)一步得到改善。充水的叫 “水壓機(jī) ”；充油的稱 “油壓機(jī) ”。執(zhí) 行元件 (如液壓缸和液壓馬達(dá) )的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動負(fù)載作直線往復(fù)運(yùn)動或回轉(zhuǎn)運(yùn)動。 iron and steel industry metallurgical machinery, lifting equipment, such as roller adjustment device。 the said oilfilled hydraulic machine. Each of the two liquid a sliding piston, if the increase in the small piston on the pressure of a certain value, according to Pascal39。s law, small piston to the pressure of the pressure through the liquid passed to the large piston, piston top will go a long way to go. Based crosssectional area of the small piston is S1, plus a small piston in the downward pressure on the F1. Thus, a small piston on the liquid pressure to P = F1/SI, Can be the same size in all directions to the transmission of liquid. By the large piston is also equivalent to the inevitable pressure P. If the large piston is the crosssectional area S2, the pressure P on the piston in the upward pressure generated F2 = PxS2 Crosssectional area is a small multiple of the piston crosssectional area. From the type known to add in a small piston of a smaller force, the piston will be in great force, for which the hydraulic machine used to suppress plywood, oil, extract heavy objects, such as forging steel. History of the development of hydraulic And air pressure drive hydraulic fluid as the transmission is made according to the 17th century, Pascal39。 civil water projects with flood control the dam gate
