產(chǎn)品說(shuō)明
4WS(E)2EM10-5X/...
4WS(E)2EM10-5X 型閥門(mén)是電動(dòng)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(mén)由機電轉換器（力矩馬達）、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(guò)機械反饋連接到力矩馬達）組成。
力矩馬達線(xiàn)圈上的電氣輸入信號通過(guò)磁體產(chǎn)生作用于電樞的力，并與彈性管 一起產(chǎn)生扭矩。這導致通過(guò)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(kāi)，并且在控制閥芯的前側產(chǎn)生壓差。該壓差導致控制閥芯改變位置，并導致壓力油口連接一個(gè)執行機構油口，同時(shí)，另一個(gè)執行機構油口連接到回流油口。
控制閥芯通過(guò)彎曲彈簧（機械反饋）連接到擋板或力矩馬達�？刂崎y芯的位置將改變，直到彎曲彈簧的反饋扭矩和力矩馬達的電磁扭矩達到平衡并且噴嘴擋板系統的壓差變?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(lái)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(mén)并放大模擬輸入信號（控制值），以便通過(guò)輸出信號以流量控制形式驅動(dòng)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(lèi)型進(jìn)行過(guò)調整的控制電子元件 (10)。它們與力矩馬達蓋帽相連接。閥零位可以通過(guò)可從外部檢修的電位計進(jìn)行調整。
4WSE2ED10-5X/...
對于通過(guò)復位彈簧的機械控制，此類(lèi)型的閥門(mén)還配備有電氣閥芯位置檢測和控制裝置�？刂崎y芯位置由感應式位置傳感器確定。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。具有附加電氣反饋時(shí)，與純機械型號相比，電氣控制器放大率可在較小信號范圍內達到較高動(dòng)態(tài)值。另外提供的機械反饋可確保在電源故障時(shí)，閥芯位于零范圍內。
閥門(mén)僅與集成控制電子元件配合使用。閥零位可以通過(guò)可從外部檢修的電位計進(jìn)行調整。
注意：更改零電位可能導致系統損壞，故只能由的專(zhuān)業(yè)人員執行。
