變量軸向柱塞泵A4VSO180DR/30R-PPB13N00
南京澤登機電設備有限公司專業(yè)代理銷售力士樂A4V,A10V,A11V系列柱塞泵
力士樂A4V柱塞泵變量原理就是通過LS(負載敏感)來控制,當執(zhí)行元件壓力變化時,LS把執(zhí)行元件的壓力情況反饋給泵上的LS閥,LS閥給力士樂A4V柱塞泵變量泵里的柱塞施加壓力,改變斜盤的角度,從而實現(xiàn)變量.當系統(tǒng)有多個執(zhí)行元件時,取壓力最大的執(zhí)行元件
變量泵的變量控制我知道的一般有兩種形式，1：電控；2液控。電控大多采用電比例信號控制比例閥的開口量，通過變量油缸從而改變斜盤角度達到變量目的。液控形式與電控原理沒有本質區(qū)別。只是閥的控制形式改為液控。亦稱LS。有隨動伺服的也有壓力反饋控制的。
