A4VS0180DFE1Z/30R-PZB25U99力士樂柱塞泵江蘇
南京軒創(chuàng)機(jī)電貿(mào)易有限公司代理銷售力士樂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(fù)載敏感)來控制,當(dāng)執(zhí)行元件壓力變化時(shí),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(shí)現(xiàn)變量.當(dāng)系統(tǒng)有多個(gè)執(zhí)行元件時(shí),取壓力大的執(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(hào)控制比例閥的開口量，通過變量油缸從而改變斜盤角度達(dá)到變量目的。液控形式與電控原理沒有本質(zhì)區(qū)別。只是閥的控制形式改為液控。亦稱LS。有隨動(dòng)伺服的也有壓力反饋控制的。
部分型號(hào)，如有什么需要或疑問可來電垂詢，謝謝合作！
