       DPZO-LES-BC-251-S3伺服比例閥-特價ATOS阿托斯在使用伺服閥和比例閥的過程中，我們經(jīng)常會發(fā)現(xiàn)伺服閥滯環(huán)比比例閥高，尤其是單級的閥。不是說伺服閥的控制精度比比例閥高嗎，為啥它的滯換比較大呢？這個問題一直困擾著我；它是否也一直困擾著你呢？接下來和我一起探討吧。

1. 控制精度

控制精度主要與伺服閥和比例閥的靜態(tài)性能和動態(tài)性能有關，是靜態(tài)性能和動態(tài)性能共同決定的。說那類閥的控制精度高應該結合具體的控制系統(tǒng)來考慮。

2. 伺服閥的滯環(huán)比比例閥大

伺服閥通常是機械反饋，滯環(huán)是機械滯環(huán)和電氣共滯環(huán)同疊加的結果。DPZO-LES-BC-251-S3伺服比例閥-特價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. 伺服閥的動態(tài)性能一般比比比例好。

4. DPZO-LES-BC-251-S3伺服比例閥-特價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。

面對著那么多的比例閥、伺服閥和高頻響閥，我們該如何選擇？哪一個才是我們需要的？

首先，對應用的分析，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，可以計算單個回路閥的流量需求。

動態(tài)特性：加/減速度、循環(huán)時間、精度、是否考慮閉環(huán)等。

根據(jù)產(chǎn)品結構和性能，控制閥主要包括三類：

比例閥

伺服閥

伺服比例閥，或叫高頻響閥

比例閥

實際流量按額定流量的~90%考慮

避免過高壓降。如果閥壓降超過系統(tǒng)壓力的50%，閥芯工作不穩(wěn)定

更大的流量，額定流量可達1000L/min
