商品詳情
力士樂伺服閥4WRPEH6C3B02L-3X/M/24F1 現貨伺服閥的目的就是：以電控方式實現對流量的節流控制（當然經過結構上的改動也可實現壓力控制等），既然是節流控制，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伺服閥的主閥一般來說和換向閥一樣是滑閥結構，只不過閥芯的換向不是靠電磁鐵來推動，而是靠前置級閥輸出的液壓力來推動，這一點和電液換向閥比較相似，只不過電液換向閥的前置級閥是電磁換向閥，而伺服閥的前置級閥是動態特性比較好的噴嘴擋板閥或射流管閥。
也就是說，伺服閥的主閥是靠前置級閥的輸出壓力來控制的，而前置級閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置級閥就不能輸出足夠的壓力來推動主閥芯動作。

也就是說，伺服閥的主閥是靠前置級閥的輸出壓力來控制的，而前置級閥的壓力則來自于伺服閥的入口p，假如p口的壓力不足，前置級閥就不能輸出足夠的壓力來推動主閥芯動作。
而我們知道，當負載為零的時候，如果四通滑閥完全打開，p口壓力=t口壓力+閥口壓力損失（忽略油路上的其它壓力損失），如果閥口壓力損失很小，t口壓力又為零，那么p口的壓力就不足以供給前置級閥來推動主閥芯，整個伺服閥就失效了。所以伺服閥的閥口做得偏小，即使在閥口全開的情況下，也要有一定的壓力損失，來維持前置級閥的正常工作。
