博世力士樂(lè)高頻響閥和伺服閥,4WEH22Y31-7X/6HG24N9ETK4,REXROTH伺服閥
博世力士樂(lè)高頻響閥和伺服閥的主閥一般來(lái)說(shuō)和換向閥一樣是滑閥結(jié)構(gòu),只不過(guò)閥芯的換向不是靠電磁鐵來(lái)推動(dòng),而是靠前置閥輸出的液壓力來(lái)推動(dòng),這一點(diǎn)和電液換向閥比較相似,只不過(guò)電液換向閥的前置閥是電磁換向閥,而伺服閥的前置閥是動(dòng)態(tài)特性比較好的噴嘴擋板閥或射流管閥。 也就是說(shuō),伺服閥的主閥是靠前置閥的輸出壓力來(lái)控制的,而前置閥的壓力則來(lái)自于伺服閥的入口p,假如p口的壓力不足,前置閥就不能輸出足夠的壓力來(lái)推動(dòng)主閥芯動(dòng)作。
