Rexroth力士樂手動(dòng)換向閥的配合作用。我們用一個(gè)手動(dòng)換向閥和液壓絞車的例子來做對(duì)比。操作員推動(dòng)手動(dòng)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(shí),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(shí),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(dòng)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(dòng)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)。
