Rexroth力士樂4WRE 10 E25-2X/G24K4/V比例換向閥
型號 4WRE...-2X/...
在閥板設(shè)計中兩位四通及三位四通比例方向閥用作直動式設(shè)備。通過帶對中螺紋和可拆卸線圈的比例電磁鐵進行操作。線圈由外部電子元件進行控制。
設(shè)置:
閥門的基本構(gòu)成包括:
帶連接面的殼體 (1) ‐
帶有壓縮彈簧(3 和 4)與彈簧座(5 和 6)的控制閥芯 (2) ‐
帶對中螺紋的線圈(7 和 8) ‐
位置傳感器 (9) ‐
功能:
線圈(7 和 8)斷電后,位于彈簧座(5 和 6)之間的壓縮彈簧(3 和 4)可將控制閥芯 (2) 置于中心位置 ‐
可通過控制比例電磁鐵(例如,線圈“b”(8))直接操作控制閥芯 (2) ‐
控制閥芯 (2) 與電氣輸入信號成比例地向左移動 ?
通過具有漸進流量特性的節(jié)流橫截面, ?
進行從 P 到 A 及從 B 到 T 的連接 ?
關(guān)閉線圈 (8) ‐
控制閥芯 (2) 在壓縮彈簧 (3) 的作用下返回到中心位置 ?
在斷電狀態(tài)下,線圈的復(fù)位彈簧使得控制閥芯 (2) 保持在機械中心位置。使用帶有符號“V”的控制閥芯時,此位置與液壓中心位置不對應(yīng)!電動閥控制環(huán)關(guān)閉時,控制閥芯將位于液壓中心位置。
重要注意事項:
PG 裝配 (11) 不得打開。位于下方的調(diào)節(jié)螺母的機械調(diào)節(jié)已禁用,該操作會損壞閥門!
帶兩個閥芯位置的閥門:(型號 4WRE…A...)
基本上,此型號閥的功能與帶三個閥芯位置的閥門功能相對應(yīng)。但是,此雙閥芯位置閥僅配有線圈“a”(7)。它配有保護塞 (10) 來代替第二個比例電磁鐵。
注意:
由于設(shè)計原理,閥內(nèi)固有內(nèi)部泄漏,泄漏量可能隨著使用年限而增加。
注意:
不得讓油箱管路排空運行。在相應(yīng)的安裝條件下,必須安裝一個預(yù)載閥(預(yù)載壓力約為 2 bar)。
