產(chǎn)品說明
4WS(E)2EM10-5X/...
4WS(E)2EM10-5X 型閥門是電動操作的 2 級伺服方向閥。它們主要用于控制位置、力和速率。
這些閥門由機(jī)電轉(zhuǎn)換器（力矩馬達(dá)）、液壓放大器（原理：噴嘴擋板）和套筒（第二級）中的控制閥芯（通過機(jī)械反饋連接到力矩馬達(dá)）組成。
力矩馬達(dá)線圈上的電氣輸入信號通過磁體產(chǎn)生作用于電樞的力，并與彈性管 一起產(chǎn)生扭矩。這導(dǎo)致通過螺栓連接到彈性管的擋板從兩個(gè)控制噴嘴之間的中心位置移開，并且在控制閥芯的前側(cè)產(chǎn)生壓差。該壓差導(dǎo)致控制閥芯改變位置，并導(dǎo)致壓力油口連接一個(gè)執(zhí)行機(jī)構(gòu)油口，同時(shí)，另一個(gè)執(zhí)行機(jī)構(gòu)油口連接到回流油口。
控制閥芯通過彎曲彈簧（機(jī)械反饋）連接到擋板或力矩馬達(dá)。控制閥芯的位置將改變，直到彎曲彈簧的反饋扭矩和力矩馬達(dá)的電磁扭矩達(dá)到平衡并且噴嘴擋板系統(tǒng)的壓差變?yōu)榱恪?br /> 因此，控制閥芯的行程和伺服閥的流量是與電氣輸入信號成比例來控制的。必須注意的是，流量取決于閥壓降。
外部控制電子元件，4WS2EM10-5X/... 型（單**訂購）
外部控制電子元件（伺服放大器）操作閥門并放大模擬輸入信號（控制值），以便通過輸出信號以流量控制形式驅(qū)動伺服閥。
集成控制電子元件，4WSE2EM10-5X/... 型和 4WSE2ED10-5X/... 型
要放大模擬輸入信號，需集成特別針對此閥類型進(jìn)行過調(diào)整的控制電子元件 (10)。它們與力矩馬達(dá)蓋帽相連接。閥零位可以通過可從外部檢修的電位計(jì)進(jìn)行調(diào)整。
4WSE2ED10-5X/...
對于通過復(fù)位彈簧的機(jī)械控制，此類型的閥門還配備有電氣閥芯位置檢測和控制裝置。控制閥芯位置由感應(yīng)式位置傳感器確定。由集成控制電子元件將位置傳感器信號與控制值相比較。任何可能的控制偏差都進(jìn)行電氣放大，并且作為控制信號饋送到力矩馬達(dá)。具有附加電氣反饋時(shí)，與純機(jī)械型號相比，電氣控制器放大率可在較小信號范圍內(nèi)達(dá)到較高動態(tài)值。另外提供的機(jī)械反饋可確保在電源故障時(shí)，閥芯位于零范圍內(nèi)。
閥門僅與集成控制電子元件配合使用。閥零位可以通過可從外部檢修的電位計(jì)進(jìn)行調(diào)整。
注意：更改零電位可能導(dǎo)致系統(tǒng)損壞，故只能由的專業(yè)人員執(zhí)行。
