代理德國REXROTH比例伺服閥低價供應

力士樂Rexroth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(diào)制的流量和壓力。它既是電液轉(zhuǎn)換元件,，也是功率放大元件，它能夠?qū)⑿」β实奈⑷蹼姎廨斎胄盘栟D(zhuǎn)換為大功率的液壓能（流量和壓力）輸出,。在電液伺服系統(tǒng)中,，它將電氣部分與液壓部分連接起來，實現(xiàn)電液信號的轉(zhuǎn)換與液壓放大,。電液伺服閥是電液伺服系統(tǒng)控制的核心,。

力士樂Rexroth閥對流量的控制可以分為兩種：

一種是開關控制：要么全開、要么全關,，流量要么zui大,、要么zui小，沒有中間狀態(tài),，如普通的電磁直通閥,、電磁換向閥、電液換向閥,。

另一種是連續(xù)控制：閥口可以根據(jù)需要打開任意一個開度,，由此控制通過流量的大小，這類閥有手動控制的,，如節(jié)流閥,，也有電控的，如比例閥,、伺服閥,。

所以使用比例閥或伺服閥的目的就是：以電控方式實現(xiàn)對流量的節(jié)流控制（當然經(jīng)過結(jié)構(gòu)上的改動也可實現(xiàn)壓力控制等），既然是節(jié)流控制,，就必然有能量損失,，伺服閥和其它閥不同的是，它的能量損失更大一些,，因為它需要一定的流量來維持前置級控制油路的工作,。
