DPZO-AE-171-S5比例換向閥-特價(jià)ATOS阿托斯在使用伺服閥和比例閥的過(guò)程中，我們經(jīng)常會(huì)發(fā)現(xiàn)伺服閥滯環(huán)比比例閥高，尤其是單級(jí)的閥。不是說(shuō)伺服閥的控制精度比比例閥高嗎，為啥它的滯換比較大呢？這個(gè)問(wèn)題一直困擾著我；它是否也一直困擾著你呢？接下來(lái)和我一起探討吧。
1. 控制精度
控制精度主要與伺服閥和比例閥的靜態(tài)性能和動(dòng)態(tài)性能有關(guān)，是靜態(tài)性能和動(dòng)態(tài)性能共同決定的。說(shuō)那類閥的控制精度高應(yīng)該結(jié)合具體的控制系統(tǒng)來(lái)考慮。
2. 伺服閥的滯環(huán)比比例閥大
伺服閥通常是機(jī)械反饋，滯環(huán)是機(jī)械滯環(huán)和電氣共滯環(huán)同疊加的結(jié)果。DPZO-AE-171-S5比例換向閥-特價(jià)ATOS阿托斯比例閥通常是位置反饋，滯環(huán)主要是電氣滯環(huán)。所以一般情況下，比例閥的滯環(huán)、重復(fù)精度、線性度等靜態(tài)性能參數(shù)比伺服閥好。
3. 伺服閥的動(dòng)態(tài)性能一般比比比例好。
4. DPZO-AE-171-S5比例換向閥-特價(jià)ATOS阿托斯那種閥的控制精度更高？
這主要取決于你的控制系統(tǒng)，如果你比較關(guān)注靜態(tài)性能，那么比例閥的控制精度更高；反之，則伺服閥的控制精度更高。
面對(duì)著那么多的比例閥、伺服閥和高頻響閥，我們?cè)撊绾芜x擇？哪一個(gè)才是我們需要的？
首先，對(duì)應(yīng)用的分析，重要的因素包括：
流量需求：根據(jù)執(zhí)行器期望的速度以及執(zhí)行器的大小，可以計(jì)算單個(gè)回路閥的流量需求。
動(dòng)態(tài)特性：加/減速度、循環(huán)時(shí)間、精度、是否考慮閉環(huán)等。
根據(jù)產(chǎn)品結(jié)構(gòu)和性能，控制閥主要包括三類：
