伺服閥與比例閥的區(qū)別

伺服閥與比例閥之間的差別并沒(méi)有嚴(yán)格的規(guī)定，因?yàn)楸壤y的性能越來(lái)越好，逐漸向伺服閥靠近，所以近些年出現(xiàn)了比例伺服閥。

比例閥和伺服閥的區(qū)別主要體現(xiàn)在以下幾點(diǎn)：

1.驅(qū)動(dòng)裝置不同。比例閥的驅(qū)動(dòng)裝置是比例電磁鐵；伺服閥的驅(qū)動(dòng)裝置是力馬達(dá)或力矩馬達(dá)；

2.性能參數(shù)不同。滯環(huán)、中位死區(qū)、頻寬、過(guò)濾精度等特性不同，因此應(yīng)用場(chǎng)合不同，伺服閥和伺服比例閥主要應(yīng)用在閉環(huán)控制系統(tǒng)，其它結(jié)構(gòu)的比例閥主要應(yīng)用在開(kāi)環(huán)控系統(tǒng)及閉環(huán)速度控制系統(tǒng)；

2.1 伺服閥中位沒(méi)有死區(qū)，比例閥有中位死區(qū)；

2.2 伺服閥的頻響（響應(yīng)頻率）更高，可以高達(dá)200Hz左右，比例閥一般最高幾十Hz；

2.3 伺服閥對(duì)液壓油液的要求更高，需要經(jīng)過(guò)濾才行，否則容易堵塞，比例閥要求低一些；

3.閥芯結(jié)構(gòu)及加工精度不同。比例閥采用閥芯+閥體結(jié)構(gòu)，閥體兼作閥套。伺服閥和伺服比例閥采用閥芯+閥套的結(jié)構(gòu)。

4.中位機(jī)能種類(lèi)不同。比例換向閥具有與普通換向閥相似的中位機(jī)能，而伺服閥中位機(jī)能只有O型（Rexroth產(chǎn)品的E型）。

5.閥的額定壓降不同。

而比例伺服閥性能介于伺服閥和比例閥之間。

比例換向閥屬于比例閥的一種，用來(lái)控制流量和流向。
