變量軸向柱塞泵A4VSO180DR/30R-PPB13N00
南京澤登機(jī)電設(shè)備有限公司專(zhuān)業(yè)代理銷(xiāo)售力士樂(lè)A4V,A10V,A11V系列柱塞泵
    力士樂(lè)A4V柱塞泵變量原理就是通過(guò)LS(負(fù)載敏感)來(lái)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(lè)A4V柱塞泵變量泵里的柱塞施加壓力,改變斜盤(pán)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(hào)控制比例閥的開(kāi)口量，通過(guò)變量油缸從而改變斜盤(pán)角度達(dá)到變量目的。液控形式與電控原理沒(méi)有本質(zhì)區(qū)別。只是閥的控制形式改為液控。亦稱(chēng)LS。有隨動(dòng)伺服的也有壓力反饋控制的。
