液壓傳動(dòng)-利用液壓實(shí)現(xiàn)運(yùn)動(dòng)和動(dòng)力傳動(dòng)-利用氣壓實(shí)現(xiàn)運(yùn)動(dòng) 動(dòng)力傳動(dòng)方式 開發(fā)研究的第1階段:17世紀(jì)帕斯卡制定了液壓傳動(dòng)的靜壓傳動(dòng)原理1795年，世界上第一臺(tái)液壓機(jī)誕生，已有200多年的歷史但由于液壓傳動(dòng)技術(shù)和液壓元件不成熟，工藝制造水平低，發(fā)展緩慢，幾乎停滯不前。
早在公元前，埃及人就嘗試用風(fēng)箱帶來壓縮空氣系統(tǒng)引燃從18世紀(jì)產(chǎn)業(yè) 革命開始，逐漸應(yīng)用于各類行業(yè)中 第二階段：上世紀(jì)30年代，由于工藝制造水平提高，開始生產(chǎn)液壓元件，并首先應(yīng)用于機(jī)床 第三階段:上世紀(jì)50.60.20世紀(jì)70年代，工藝水平大大提高，液壓氣動(dòng)技液壓泵術(shù)發(fā)展迅速，滲透到國民經(jīng)濟(jì)的各個(gè)領(lǐng)域：從藍(lán)天到水下，從軍事到民用，從重工業(yè)到輕工業(yè)，到處都有流體傳動(dòng)和控制技術(shù)。
舉例應(yīng)用如：火炮跟蹤、飛機(jī)和導(dǎo)彈的動(dòng)、炮塔穩(wěn)定、海底石油探測(cè)平臺(tái)固定、煤礦礦井支承、礦山用的風(fēng)鉆、火車的剎車裝置、液壓裝載、起重、挖掘、軋鋼機(jī)組、數(shù)控機(jī)床、多工位組合機(jī)床、全自動(dòng)液壓車床、液壓機(jī)械手等。
中國的液壓和氣動(dòng)技術(shù)自20世紀(jì)60年代以來發(fā)展迅速新產(chǎn)品的開發(fā)和開發(fā)與先進(jìn)國家一樣好，但其發(fā)展速度遠(yuǎn)遠(yuǎn)落后于同期的日本主要原因是工藝制造水平跟不上，制造難度大，材料性能無法滿足 設(shè)計(jì)需要，影響了我國流體傳動(dòng)技術(shù)的發(fā)展。
希望在坐各位能用自己所學(xué)為我國的流體傳動(dòng)技術(shù)作出應(yīng)有液壓泵的貢獻(xiàn)簡而言之，流體技術(shù)+電氣控制就像一只插上翅膀的老虎它把一個(gè)人和一把刀變成一把無人的刀，把復(fù)雜的過程變成一個(gè)簡單的過程現(xiàn)在，再加上計(jì)算機(jī)控制，它將進(jìn)入一個(gè)新的歷史階段。
液壓傳動(dòng)的工作原理 特點(diǎn) （1）用具有一定壓力的流體來傳動(dòng) （2）傳動(dòng)過程中必須經(jīng)過兩次能量轉(zhuǎn)換 （3）傳動(dòng)必須在密封容器內(nèi)進(jìn)行，而且容積要發(fā)生變化液壓系統(tǒng)的組成和作用 1.動(dòng)力裝置—液壓泵將電動(dòng)機(jī)發(fā)送的機(jī)械能配置轉(zhuǎn)變成流體或氣體的壓力能。
2.執(zhí)行裝置—液壓缸（或馬達(dá)）將流體壓力能轉(zhuǎn)換為機(jī)械能，而對(duì)負(fù)載作功 3.控制調(diào)節(jié)配置-控制液壓泵流體方向、壓力和流量的各種液壓控制閥，以確保執(zhí)行部件完成預(yù)期的任務(wù) 4.輔助配置—油箱、油管、濾油器、壓力表、冷卻器、分水濾水器、油霧器、消聲器、管件、管接頭和種信號(hào)轉(zhuǎn)換器等，創(chuàng)造必要條件，保證系統(tǒng)正常工作。
5.工作介質(zhì)-液壓油或壓縮空氣系統(tǒng)動(dòng)和動(dòng)力的載體 液壓傳動(dòng)的優(yōu)點(diǎn)：獨(dú)特之處—力大無窮（P=32MP以上） 如:所拿液壓千斤頂，可頂起1.6噸重物，若每位男同學(xué)體重為128斤，可舉起25位男同學(xué) 液壓傳動(dòng)的缺點(diǎn)： 1.不宜遠(yuǎn)距離傳遞 2.泄漏嚴(yán)重,不宜保證嚴(yán)格的傳動(dòng)比 3.污染地面液壓泵 4.對(duì)T變化敏感 5.難于檢查故障 90-L-055-KA-5-BC-60-S-3-S1-C-03-GBA-35-35-24 90L055KA5BC60S3S1C03GBA353524 90-L-055-KA-5-BC-60-S-3-S1-C-03-GBA-42-42-24
