A10VSO10DR/52R-PPA14N00E柱塞泵

控制加速度和減速度的傳統(tǒng)方法有：換向閥切換時間遲延、液壓缸缸內(nèi)端位緩沖、電子控制流量閥和變量泵等。用比例方向閥和斜坡信號發(fā)生器可以提供很好的解決方案，這樣就可以提高機器的循環(huán)速度并防止慣性沖擊。工作特點:1.比例換向閥、比例減壓閥、比例溢流閥的工作特點比例閥是一種按輸入的電信號連續(xù)地、按比例地控制液壓系統(tǒng)的液流方向、流量和壓力的閥類。按用途和工作特點的不同，比例閥可分為比例換向閥、比例壓力閥、比例流量閥和比例復(fù)合閥四類。根據(jù)本系統(tǒng)的功能要求，初選比例換向閥、比例減壓閥和比例溢...
