現(xiàn)貨特價(jià)型號(hào)：4WEH16E7X/6HG24N9ETK4/B10 2臺(tái)伺服閥的主閥一般來說和換向閥一樣是滑閥結(jié)構(gòu)，只不過閥芯的換向不是靠電磁鐵來推動(dòng)，而是靠前置級(jí)閥輸出的液壓力來推動(dòng)，這一點(diǎn)和電液換向閥比較相似，只不過電液換向閥的前置級(jí)閥是電磁換向閥，而伺服閥的前置級(jí)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，伺服閥的主閥是靠前置級(jí)閥的輸出壓力來控制的，而前置級(jí)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(jí)閥就不能輸出足夠的壓力來推動(dòng)主閥芯動(dòng)作。
而我們知道，當(dāng)負(fù)載為零的時(shí)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(jí)閥來推動(dòng)主閥芯，整個(gè)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(jí)閥的正常工作。 MOOG J761-004

伺服閥其實(shí)缺點(diǎn)極多：能耗浪費(fèi)大、容易出故障、抗污染能力差、價(jià)格昂貴等等等等，好處只有一個(gè)：動(dòng)態(tài)性能是所有液壓閥中最高的。就憑著這一個(gè)優(yōu)點(diǎn)，在很多對(duì)動(dòng)態(tài)特性要求高的場(chǎng)合不得不使用伺服閥，如飛機(jī)火箭的舵機(jī)控制、汽輪機(jī)調(diào)速等等。動(dòng)態(tài)要求低一點(diǎn)的，基本上都是比例閥的天下了。力士樂Rexroth 2FR 比例流量閥

一般說來，好像伺服系統(tǒng)都是閉環(huán)控制，比例多用于開環(huán)控制；其次比例閥類型要多，有比例壓力、流量控制閥等，控制比伺服要靈活一些。從他們內(nèi)部結(jié)構(gòu)看，伺服閥多是零遮蓋，比例閥則有一定的死區(qū)，控制精度要低，響應(yīng)要慢。但從發(fā)展趨勢(shì)看，特別在比例方向流量控制閥和伺服閥方面，兩者性能差別逐漸在縮小，另外比例閥的成本比伺服閥要低許多，抗污染能力也強(qiáng)！0811404145 4WRPE6W08SJ-2X/G24KO/A1M
