卸荷溢流閥的工作原理

摘要:
一、工作原理
卸荷溢流閥是由溢流閥和止回閥。當系統壓力達到溢流閥開啟壓力時,溢流閥,泵卸荷;當系統壓力降的關閉溢流閥,安全閥關閉,泵系統負載。卸載壓力稱為卸載泵壓力,泵的壓力稱為負載加載條件。
二、卸荷溢流閥的功能和應用
卸荷溢流閥的主要功能是自動控制泵的卸荷或加載。針對函數卸貨卸荷溢流閥的壓力和負載壓力是有區別的。
差異過小,泵經常卸載和加載;差異太大,那么系統壓力變化太大了。裝卸的區別是一個壓力卸荷溢流閥的重要,能指標,一般負載85%壓力卸載。它的性能是一樣的溢流閥。
三、卸荷溢流閥的主要目的
1、自動蓄能器系統泵卸載和加載;
2、高低壓泵組合中大低壓泵卸載。
四、卸荷溢流閥的選擇
卸荷溢流閥主要用于液壓回路包含蓄電池,蓄電池充電時壓力達到閥設定壓力時自動使液壓泵卸貨。止回閥的閥有一個內置的防止反向蓄能器的壓力油。此時的蓄電池維護系統和油泵卸載得到節能效果。
當蓄能器的油壓閥設定壓力85%左右,閥和復雜的載荷,液壓泵的蓄電池充電的復蘇。這種閥還可用于高、低電壓電路雙泵。兩泵低壓供油系統同時,高壓閥泵卸載時,將高壓部分。蓄電池之間的閥和蓄能器壓力不得超過設定壓力10%泄露管閥排水嘴2%壓力不得超過設定壓力。
