Rexroth力士樂(lè )手動(dòng)換向閥,REXROTH換向閥,德力士樂(lè )換向閥
Rexroth力士樂(lè )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(chē)的例子來(lái)做對比。操作員推動(dòng)手動(dòng)閥，滑閥行程為20%，絞車(chē)滾筒以5RPM速度旋轉。為了說(shuō)明原理，我們把換向閥比做固定節流環(huán)。當節流環(huán)進(jìn)出口兩端的壓降不斷降低，流經(jīng)節流環(huán)的流量則相應減少。當絞車(chē)的負載增加時(shí)，節流環(huán)（換向閥）出口的負載感應壓力亦相應增加。此時(shí)，流經(jīng)節流環(huán)（換向閥）的壓降降低，節流環(huán)的流量減少，絞車(chē)速度開(kāi)始減慢。在負載感應回路中，節流環(huán)（換向閥）出口的負載感應壓力通過(guò)換向閥的負載感應梭閥網(wǎng)絡(luò )傳變量排污泵的控制閥。變量排污泵的負載感應控制閥即刻響應增加的感應壓力，推動(dòng)斜盤(pán)使排污泵排量緩緩增加，節流環(huán)（換向閥）進(jìn)口的壓力開(kāi)始上升。這種作用可以維持節流環(huán)（換向閥）進(jìn)出口的壓力恒定，流量恒定，從而達到絞車(chē)速度的恒定。節流環(huán)（換向閥）進(jìn)出口的壓降 delta P 維持在10-30公斤。當所有換向閥回到中位，負載感應壓力釋放油箱，排污泵負載感應控制閥維持在相當于或略高于設定壓降值，變量排污泵處于起始待命狀態(tài)。由于變量排污泵只根據負載感應驅動(dòng)器的指令大小來(lái)輸出流量，負載感應控制方式無(wú)節流發(fā)熱損耗，節能效應。
