萬福樂比例閥WDPFA06-ACB-S-5-G24現(xiàn)貨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)動裝置不同。比例閥的驅(qū)動裝置是比例電磁鐵;伺服閥的驅(qū)動裝置是力馬達(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、過濾精度等特性不同,因此應(yīng)用場合不同,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gao幾十Hz;
2.3 伺服閥對液壓油液的要求更高,需要經(jīng)過濾才行,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。
