?液壓泵的使用壽命較長(zhǎng)，流量越大，泵的工作性能越好因此，可以通過(guò)使用不同的輸送介質(zhì)來(lái)獲得不同的性能根據(jù)不同的要求，還可以調(diào)節(jié)泵軸的轉(zhuǎn)速、位置及流量等參數(shù)通常情況下，電機(jī)輸出扭矩（額定扭矩）之間不超過(guò)0.35~0.45倍額定轉(zhuǎn)速范圍內(nèi)的最大扭矩；電機(jī)電流、轉(zhuǎn)速、扭矩之間的關(guān)系與轉(zhuǎn)速成正比。
一般來(lái)說(shuō)，對(duì)于扭矩和轉(zhuǎn)速來(lái)說(shuō)，電機(jī)和減速機(jī)是相同的當(dāng)電機(jī)負(fù)載不變時(shí)，電機(jī)的轉(zhuǎn)矩基本相同，這意味著轉(zhuǎn)矩大小不變，而且它們具有一定的相位關(guān)系當(dāng)電機(jī)負(fù)載越大時(shí)轉(zhuǎn)矩越小（不大于4轉(zhuǎn)/分鐘）因此如果是很小并且采用相同的傳動(dòng)比時(shí)，電機(jī)和減速機(jī)的功率輸出是相同的。
可以通過(guò)調(diào)節(jié)轉(zhuǎn)矩以減少電流；當(dāng)電機(jī)負(fù)載較低時(shí)，功率輸出能力可以大大提高；此時(shí)可以節(jié)省能量或減少磨損功率是指輸出扭矩與電機(jī)功率之比在正常情況下，功率和輸出功率是成正比的當(dāng)電流過(guò)大時(shí)將產(chǎn)生負(fù)載過(guò)載而損壞機(jī)器；由于功率消耗大，效率低等原因，導(dǎo)致停機(jī)時(shí)間大大增加；即使功率超過(guò)允許值，速度也不應(yīng)該超過(guò)額定值（一般超過(guò)額定轉(zhuǎn)速),因?yàn)槿绻话凑赵O(shè)計(jì)運(yùn)行，電流將增加，電機(jī)和減速機(jī)將不會(huì)正常工作；速度提高了會(huì)增加油耗，并引起其他故障。
當(dāng)電流超過(guò)允許值時(shí)可能導(dǎo)致事故發(fā)生因此需要進(jìn)行檢修或者更換泵體，以防止停機(jī)時(shí)間太長(zhǎng)造成資源浪費(fèi)和安全事故等后果發(fā)生為了獲得最大范圍的輸出功率和壽命，可以采用以下幾種方法：在泵軸上安裝高流量閥門來(lái)控制其速度大小以達(dá)到穩(wěn)定運(yùn)行狀態(tài)。
如果泵工作在低速以下（≤1小時(shí)）而不損壞泵，只會(huì)影響流量與使用壽命例如：在生產(chǎn)過(guò)程中應(yīng)用小流量高壓泵來(lái)輸送液體時(shí)會(huì)造成液體中雜質(zhì)堵塞管路或使其變得更容易被損壞并使閥門失效根據(jù)具體情況選擇液壓泵電機(jī)可以實(shí)現(xiàn)更高使用壽命。
