?液壓系統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生推力，活塞在液壓介質中往復運動實現位移，柱塞實現往復運動實現傳遞能量和動力。
如果油液中存在液體雜質或者受到外界雜質影響，導致介質不均勻受力或者油中雜質過多等因素造成摩擦，會使液壓系統產生較大阻力實現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 工作壓力：液壓缸、柱塞等元件在工作中由于受到介質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生事故并引起缸體損壞，因此壓力一定要保持在一個適當的范圍內2、流量：液壓缸內液體在靜止狀態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；流量(L)與壓力成正比。
3、壓力：液壓系統中空氣或水是不能進行直接液壓循環（包括液體循環);液體中不能有氣體或水4、耐腐蝕：液壓系統有很強耐酸堿性介質腐蝕能力5、導流性能：當液壓缸內壓力升高或降低時產生阻力以保證缸體內產生較大壓力時必須考慮導流槽內泄漏問題。
