液壓泵是液壓系統(tǒng)的動(dòng)力元件，其功用是給液壓系統(tǒng)提供壓力油，從能量轉(zhuǎn)換角度講，它將是原動(dòng)機(jī)（如發(fā)動(dòng)機(jī)）輸出的機(jī)械能轉(zhuǎn)換為便于輸送的液體的壓力能。液壓馬達(dá)則屬于執(zhí)行元件，它能將輸入液體的壓力能轉(zhuǎn)換為輸出軸轉(zhuǎn)動(dòng)的機(jī)械能，用來拖動(dòng)負(fù)載做功。根據(jù)結(jié)構(gòu)形式，液壓泵與液壓馬達(dá)具體可分為齒輪式、葉片式、柱塞式等類型。
1.液壓泵壓力
液壓泵工作壓力是指泵（或馬達(dá)）在實(shí)際工作時(shí)輸出（或輸入）油液的壓力，由外負(fù)載決定。
額定壓力是指在正常工作條件下，按試驗(yàn)標(biāo)準(zhǔn)規(guī)定能連續(xù)運(yùn)轉(zhuǎn)的最高壓力。其大小受壽命的限制，若超過額定壓力工作，泵（或馬達(dá)）的使用壽命將會(huì)比設(shè)計(jì)的壽命短。當(dāng)工作壓力大于額定壓力時(shí)稱超載。
2.轉(zhuǎn)速
工作轉(zhuǎn)速是指泵（或馬達(dá)）在工作時(shí)的實(shí)際轉(zhuǎn)動(dòng)速度。
額定轉(zhuǎn)速是指在額定壓力下，能連續(xù)長時(shí)間正常運(yùn)轉(zhuǎn)的最高轉(zhuǎn)速。若泵超過額定轉(zhuǎn)速工作將會(huì)造成吸油不足，產(chǎn)生振動(dòng)和大的噪聲，零件會(huì)遭受氣蝕損傷，壽命降低。
最低穩(wěn)定轉(zhuǎn)速是指馬達(dá)正常運(yùn)轉(zhuǎn)所允許的最低轉(zhuǎn)速。在此轉(zhuǎn)速下，馬達(dá)不出現(xiàn)爬行現(xiàn)象。
3.排量、流量
排量是指泵（或馬達(dá)）每轉(zhuǎn)一周，由密封容腔幾何尺寸變化而得的排出（或輸入）液體的體積，常用單位是ml/r（毫升/轉(zhuǎn)）。排量可以通過調(diào)節(jié)發(fā)生變化的成為變量泵（或變量馬達(dá)），排量不能變化的成為定量泵（或定量馬達(dá)）。
實(shí)際流量是指泵（或馬達(dá)）工作時(shí)出口處（或進(jìn)口處）的流量。由于泵本身存在內(nèi)泄漏，其實(shí)際流量小于理論流量。由于馬達(dá)本身也存在內(nèi)泄漏，要實(shí)現(xiàn)指定轉(zhuǎn)速，為補(bǔ)償泄漏量，其輸入實(shí)際流量必須大于理論流量。
4.效率
容積效率，對(duì)液壓泵是指其實(shí)際流量與理論流量的比值。對(duì)液壓馬達(dá)是指其理論流量與實(shí)際流量的比值。
機(jī)械效率，對(duì)液壓泵是指其理論轉(zhuǎn)矩與實(shí)際輸入轉(zhuǎn)矩的比值。對(duì)液壓馬達(dá)其實(shí)際輸出的轉(zhuǎn)矩為理論轉(zhuǎn)矩克服摩擦力后的轉(zhuǎn)矩，因此其機(jī)械效率為實(shí)際輸出轉(zhuǎn)矩與理論轉(zhuǎn)矩的比值。
總效率是指泵（或馬達(dá)）的輸出功率與輸入功率的比值?？傂实扔谌莘e效率與機(jī)械效率的乘積。
