伺服阀与比例阀的区别
伺服阀与比例阀之间的差别并没有严格的规定,因为比例阀的性能越来越好,逐渐向伺服阀靠近,所以近些年出现了比例伺服阀。
比例阀和伺服阀的区别主要体现在以下几点:
1.驱动装置不同。比例阀的驱动装置是比例电磁铁;伺服阀的驱动装置是力马达或力矩马达;
2.性能参数不同。滞环、中位死区、频宽、过滤精度等特性不同,因此应用场合不同,伺服阀和伺服比例阀主要应用在闭环控制系统,其它结构的比例阀主要应用在开环控系统及闭环速度控制系统;
2.1 伺服阀中位没有死区,比例阀有中位死区;
2.2 伺服阀的频响(响应频率)更高,可以高达200Hz左右,比例阀一般*高几十Hz;
2.3 伺服阀对液压油液的要求更高,需要经过滤才行,否则容易堵塞,比例阀要求低一些;
3.阀芯结构及加工精度不同。比例阀采用阀芯+阀体结构,阀体兼作阀套。伺服阀和伺服比例阀采用阀芯+阀套的结构。
4.中位机能种类不同。比例换向阀具有与普通换向阀相似的中位机能,而伺服阀中位机能只有O型(Rexroth产品的E型)。
5.阀的额定压降不同。
而比例伺服阀性能介于伺服阀和比例阀之间。
比例换向阀属于比例阀的一种,用来控制流量和流向。
