力士樂Rexroth伺服閥*熱賣，對閥門有些了解的朋友應該聽過電磁閥吧，那么伺服閥呢，又有多少朋友了解過呢，不同的閥門有不同的作用，伺服閥的作用是怎樣的呢？它在工業生產和日常生活中又起到怎樣的作用呢？下面關于Rexroth力士樂伺服閥的介紹或許能為您解惑，讓您對伺服閥有個初步的了解。
力士樂Rexroth伺服閥*熱賣，Rexroth力士樂伺服閥是德國制造的一款閥門，其中有一種伺服閥叫做液控伺服閥，液控伺服閥主要是指電液伺服閥,它在接受電氣模擬信號后，相應輸出調制的流量和壓力。它既是電液轉換元件，也是功率放大元件，它能夠將小功率的微弱電氣輸入信號轉換為大功率的液壓能（流量和壓力）輸出。在電液伺服系統中，它將電氣部分與液壓部分連接起來，實現電液信號的轉換與液壓放大。電液伺服閥是電液伺服系統控制的核心。液控伺服閥是在伺服系統中將電信號輸入轉換為功率較大的壓力或流量壓力信號輸出的執行元件。它是一種電液轉換和功率放大元件。伺服閥的靈敏度高，快速性好，能將很小的電信號（例如10毫安）轉換成很大的液壓功率（如幾十匹馬力以上），可以驅動多種類型的負載。過去人們曾把噴嘴檔板閥、射流管或滑閥伺服馬達等液壓放大裝置都列入伺服閥范圍內。20世紀70年代以來，伺服閥一般僅指電液伺服閥。
，Rexroth力士樂伺服閥廣泛地應用于電液位置,速度,加速度,力伺服系統,以及伺服振動發生器中.它具有體積小,結構緊湊,功率放大系數高,控制精度高,直線性好,死區小,靈敏度高,動態性能好以及響應速度快等優點。
Rexroth力士樂伺服閥主要用在電氣液壓伺服系統中作為執行元件。在伺服系統中，液壓執行機構同電氣及氣動執行機構相比，具有快速性好、單位重量輸出功率大、傳動平穩、抗干擾能力強等特點。另一方面，在伺服系統中傳遞信號和校正特性時多用電氣元件。因此，現代高性能的伺服系統也都采用電液方式，伺服閥就是這種系統的必需元件。
伺服閥結構比較復雜，造價高，對油的質量和清潔度要求高。新型的伺服閥正試圖克服這些缺點，例如利用電致伸縮元件的伺服閥，使結構大為簡化。另一個方向是研制特殊的工作油（如電氣粘性油）。這種工作油能在電磁的作用下改變粘性系數。利用這一性質就可通過電信號直接控制油流。
以上這些就是我所知道的關于伺服閥的一些簡單知識，如需了解更多的話，可以在我中進一步了解。我們是東莞市廣聯自動化科技有限公司，在德國不萊梅和美國華盛頓都有自己的公司，與多家國外廠家合作，下面為大家帶來Rexroth力士樂伺服閥部分現貨型號：
