REXROTH力士樂手動換向閥,德國力士樂換向閥

Rexroth力士樂手動換向閥的配合作用。我們用一個手動換向閥和液壓絞車的例子來做對比。操作員推動手動閥，滑閥行程為20%，絞車滾筒以5RPM速度旋轉(zhuǎn)。為了說明原理，我們把換向閥比做固定節(jié)流環(huán)。當(dāng)節(jié)流環(huán)進(jìn)出口兩端的壓降不斷降低，流經(jīng)節(jié)流環(huán)的流量則相應(yīng)減少。當(dāng)絞車的負(fù)載增加時，節(jié)流環(huán)（換向閥）出口的負(fù)載感應(yīng)壓力亦相應(yīng)增加。此時，流經(jīng)節(jié)流環(huán)（換向閥）的壓降降低，節(jié)流環(huán)的流量減少，絞車速度開始減慢。在負(fù)載感應(yīng)回路中，節(jié)流環(huán)（換向閥）出口的負(fù)載感應(yīng)壓力通過換向閥的負(fù)載感應(yīng)梭閥網(wǎng)絡(luò)傳至變量排污泵的控制閥。變量排污泵的負(fù)載感應(yīng)控制閥即刻響應(yīng)增加的感應(yīng)壓力，推動斜盤使排污泵排量緩緩增加，節(jié)流環(huán)（換向閥）進(jìn)口的壓力開始上升。這種作用可以維持節(jié)流環(huán)（換向閥）進(jìn)出口的壓力恒定，流量恒定，從而達(dá)到絞車速度的恒定。節(jié)流環(huán)（換向閥）進(jìn)出口的壓降
delta P
維持在10-30公斤。當(dāng)所有換向閥回到中位，負(fù)載感應(yīng)壓力釋放至油箱，排污泵負(fù)載感應(yīng)控制閥維持在相當(dāng)于或略高于設(shè)定壓降值，變量排污泵處于起始待命狀態(tài)。由于變量排污泵只根據(jù)負(fù)載感應(yīng)驅(qū)動器的指令大小來輸出流量，負(fù)載感應(yīng)控制方式無節(jié)流發(fā)熱損耗，節(jié)能效應(yīng)明顯
