?液壓系統(tǒng)的主要工作是液壓元件的換向和傳遞動力其換向過程主要是液壓缸內(nèi)的壓力值傳遞換向過程中活塞和柱塞運動速度較快，柱塞在換向過程中相對運動產(chǎn)生推力，活塞在液壓介質(zhì)中往復(fù)運動實現(xiàn)位移，柱塞實現(xiàn)往復(fù)運動實現(xiàn)傳遞能量和動力。
如果油液中存在液體雜質(zhì)或者受到外界雜質(zhì)影響，導(dǎo)致介質(zhì)不均勻受力或者油中雜質(zhì)過多等因素造成摩擦，會使液壓系統(tǒng)產(chǎn)生較大阻力實現(xiàn)換向和傳遞動力換向和傳遞動力時必須有油液的存在才能實現(xiàn) 工作壓力：液壓缸、柱塞等元件在工作中由于受到介質(zhì)壓力的作用能夠完成一定的運動工況，其壓力通常是液壓缸工作時提供給液壓系統(tǒng)的最大壓力值。
在工作時活塞和柱塞需要承受軸向荷載且不能隨意伸縮壓力一旦超過壓力極限就會發(fā)生事故并引起缸體損壞，因此壓力一定要保持在一個適當(dāng)?shù)姆秶鷥?nèi)2、流量：液壓缸內(nèi)液體在靜止?fàn)顟B(tài)下能以一定速率流動并能通過一個孔徑尺寸(mm)來表示流量(L)系數(shù)；流量(L)與壓力成正比。
3、壓力：液壓系統(tǒng)中空氣或水是不能進行直接液壓循環(huán)（包括液體循環(huán));液體中不能有氣體或水4、耐腐蝕：液壓系統(tǒng)有很強耐酸堿性介質(zhì)腐蝕能力5、導(dǎo)流性能：當(dāng)液壓缸內(nèi)壓力升高或降低時產(chǎn)生阻力以保證缸體內(nèi)產(chǎn)生較大壓力時必須考慮導(dǎo)流槽內(nèi)泄漏問題。
