派克PARKER比例换向阀
PARKER派克比例换向阀通过调节输入阀内电磁铁的电压信号来控制工作阀阀芯的移动,使阀口尺寸发生改变,从而完成与输入电压成比例的压力、流量输出的控制,改阀具有集成的电子元件,主级的阀芯位置可调。
派克PARKER比例换向阀、派克PARKER比例方向控制阀、D1/D3/D4/D8/D9/D111FT(B);D1/D3/D4/D8/D9/D111FH原装PARKER派克比例阀*, 100%*!
比例阀采用阀芯+阀体结构。伺服阀和伺服比例阀主要应用在闭环控制系统,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.阀体兼作阀套。
驱动装置不同.所以近些年出现了比例伺服阀。
比例阀一般zui高几十Hz,伺服阀中位没有死区,伺服阀对液压油液的要求更高.性能参数不同;否则容易堵塞,
用来控制流量和流向,比例阀要求低一些.比例阀有中位死区;
比例阀和伺服阀的区别主要体现在以下几点:
逐渐向伺服阀靠近,
比例换向阀属于比例阀的一种,滞环、中位死区、频宽、过滤精度等特性不同.阀的额定压降不同;比例换向阀具有与普通换向阀相似的中位机能,
而比例伺服阀性能介于伺服阀和比例阀之间,因此应用场合不同,伺服阀和伺服比例阀采用阀芯+阀套的结构。中位机能种类不同.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;因为比例阀的性能越来越好;2伺服阀的频响(响应频率)更高。阀芯结构及加工精度不同.伺服阀与比例阀之间的差别并没有严格的规定。
,可以高达200Hz左右,需要精过滤才行,而伺服阀中位机能只有O型(Rexroth产品的E型)。
