18，調速閥與溢流節流閥的主要區別是什么?
1)調速閥是節流閥與減壓閥串聯而成，而溢流節流閥是節流閥與減壓閥并聯
而成.
2)益流節流閥只能裝在進油路，而調速閥可裝在進,回油路上.
3)益流節流閥進口壓力隨負載而變:調速閥的入口壓力是定壓(溢流閥定壓)
4)溢流節流閥具有益流功能,不必單獨設置溢流閥并具有過載保護功能
5)溢流節流閥流里穩定性稍差但效率較高。
19，試分析比較進油節流調速,回油節流調速和旁路節流調速異同點
1)進,回油節流調速比較: 1)F-v特性與^均相同，當節流閥開度一定，負載
變化時引起速度變化，低速輕載時^v較好:2)回油節流可形成背壓。運動平穩;
3)回油調速實現壓力控制不容易: 4)若要求速度相同，在低速時回油節流閥開
度小，易堵。5)停車后啟動時，進油節流調速沖擊小。6)適應于輕載低速，變
工況時，兩者效率均低。7)節流閥發熱影響不同。
2，旁路節流調速特點: 1)節流閥旁接，溢流閥起安全閥作用: 2) F-V特性低
速輕載較前兩者軟，但重載高速時，^v較好;3) 承載能力隨節流閥開度
增大而減小; 4)壓力隨負載增加而增加，有節流損失無溢流損失，故效率在重
載高速時較高。
