?液壓泵的使用壽命較長，流量越大，泵的工作性能越好因此，可以通過使用不同的輸送介質來獲得不同的性能根據(jù)不同的要求，還可以調節(jié)泵軸的轉速、位置及流量等參數(shù)通常情況下，電機輸出扭矩（額定扭矩）之間不超過0.35~0.45倍額定轉速范圍內的最大扭矩；電機電流、轉速、扭矩之間的關系與轉速成正比。
一般來說，對于扭矩和轉速來說，電機和減速機是相同的當電機負載不變時，電機的轉矩基本相同，這意味著轉矩大小不變，而且它們具有一定的相位關系當電機負載越大時轉矩越?。ú淮笥?轉/分鐘）因此如果是很小并且采用相同的傳動比時，電機和減速機的功率輸出是相同的。
可以通過調節(jié)轉矩以減少電流；當電機負載較低時，功率輸出能力可以大大提高；此時可以節(jié)省能量或減少磨損功率是指輸出扭矩與電機功率之比在正常情況下，功率和輸出功率是成正比的當電流過大時將產生負載過載而損壞機器；由于功率消耗大，效率低等原因，導致停機時間大大增加；即使功率超過允許值，速度也不應該超過額定值（一般超過額定轉速),因為如果您不按照設計運行，電流將增加，電機和減速機將不會正常工作；速度提高了會增加油耗，并引起其他故障。
當電流超過允許值時可能導致事故發(fā)生因此需要進行檢修或者更換泵體，以防止停機時間太長造成資源浪費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控制其速度大小以達到穩(wěn)定運行狀態(tài)。
如果泵工作在低速以下（≤1小時）而不損壞泵，只會影響流量與使用壽命例如：在生產過程中應用小流量高壓泵來輸送液體時會造成液體中雜質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可以實現(xiàn)更高使用壽命。
