REXROTH比例電液伺服閥/A10VS028DFR1/31RPPA12N00
REXROTH比例電液伺服閥的越來越好,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);
2.參數(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zui高幾十Hz;
2.3 伺服閥對液壓油液的要求更高,需要精過濾才行,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)。
