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。為了說明原理，我們把換向閥比做固定節(jié)流環(huán)。當節(jié)流環(huán)進出口兩端的壓降不斷降低，流經節(jié)流環(huán)的流量則相應減少。當絞車的負載增加時，節(jié)流環(huán)（換向閥）出口的負載感應壓力亦相應增加。此時，流經節(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。在負載感應回路中，節(jié)流環(huán)（換向閥）出口的負載感應壓力通過換向閥的負載感應梭閥網絡傳至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，推動斜盤使排污泵排量緩緩增加，節(jié)流環(huán)（換向閥）進口的壓力開始上升。這種作用可以維持節(jié)流環(huán)（換向閥）進出口的壓力恒定，流量恒定，從而達到絞車速度的恒定。節(jié)流環(huán)（換向閥）進出口的壓降
delta P
維持在10-30公斤。當所有換向閥回到中位，負載感應壓力釋放至油箱，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器的指令大小來輸出流量，負載感應控制方式無節(jié)流發(fā)熱損耗，節(jié)能效應明顯
