液壓電機(jī)是液壓系統(tǒng)中的執(zhí)行器，將液壓泵傳輸?shù)牟ㄆ缒苻D(zhuǎn)化為機(jī)械能旋轉(zhuǎn)，從而驅(qū)動(dòng)負(fù)載 通?？磥?液壓馬達(dá)只不過是泵進(jìn)行反向能量轉(zhuǎn)換而已,但這只是一種粗淺的理解,實(shí)際上,泵和馬達(dá)在工作要求上有許多不同之處.因此,在某些應(yīng)用場(chǎng)合,作為泵的設(shè)計(jì)卻很難當(dāng)馬達(dá)使用;許多馬達(dá)的內(nèi)部結(jié)構(gòu)都與相應(yīng)類型的泵有不同的結(jié)構(gòu)特征,有些馬達(dá)根本沒有泵中相應(yīng)的零件。
泵和電機(jī)在工作要求上有一些差異 液壓泵 1.大多數(shù)使用者把泵看作在壓力下輸出流量的元件,因而更重視它的容積效率 2.泵經(jīng)常在穩(wěn)定高速下工作 3.通常希望泵在額定轉(zhuǎn)遜時(shí)能輸出高壓 4.在一定的應(yīng)用場(chǎng)合,泵通常只有一個(gè)旋轉(zhuǎn)方向。
除靜液壓傳動(dòng)裝置中的泵以外,其流量和壓力方向保持不變, 5.在大多數(shù)系統(tǒng)中泵都是連續(xù)工作的,流體溫度變化較緩慢 6.大多數(shù)泵都有安裝底座，傳動(dòng)軸不承受橫向負(fù)載 液壓馬達(dá) 1.大多敷使用者把馬達(dá)看作是在一定壓力下輸出扭矩的元件,因而更重視扭矩(即機(jī)械)效率 2.馬達(dá)的轉(zhuǎn)速范圍很寬,較長(zhǎng)時(shí)間在低速工況工作 3.馬達(dá)通常在零或非常低的轉(zhuǎn)速時(shí)才達(dá)到最高壓力 4.大多數(shù)馬達(dá)都要求旋轉(zhuǎn)方向可變。
許宇馬達(dá)還要求能以 泵方式工作:以便(在超速時(shí)）對(duì)負(fù)載進(jìn)行制動(dòng) 5.馬達(dá)在長(zhǎng)時(shí)間閑置后,開始工作時(shí)要經(jīng)受濕度的突變 6.許多電機(jī)的傳動(dòng)軸必須承受直接安裝的皮帶輪、鏈輪、齒輪或其他車輪的徑向載荷
