）由于執(zhí)行機(jī)構(gòu)進(jìn)出液壓油通過(guò)一根閥芯進(jìn)行控制，單獨(dú)控制執(zhí)行機(jī)構(gòu)兩側(cè)壓力是不可能的。因此，出油側(cè)背壓作用于執(zhí)行機(jī)構(gòu)運(yùn)動(dòng)的反方向，隨著出油側(cè)背壓升高，為保質(zhì)執(zhí)行機(jī)構(gòu)的運(yùn)動(dòng)，必須提高進(jìn)油側(cè)壓力。這樣會(huì)使得液壓系統(tǒng)消耗的功能增加，效率低，發(fā)熱增加。?

　　?采用雙閥芯技術(shù)的液壓系統(tǒng)，由于執(zhí)行機(jī)構(gòu)進(jìn)出油側(cè)閥口閥芯位置及控制方式各自獨(dú)立，互不影響，這樣通過(guò)對(duì)兩閥芯控制方式的不同組合，利用軟件編程能很好解決傳統(tǒng)單閥系統(tǒng)不能解決的問(wèn)題，同時(shí)還可以輕易實(shí)現(xiàn)傳統(tǒng)液壓系統(tǒng)中難以實(shí)現(xiàn)的功能。?

　　?我們知道，對(duì)于汽車起重機(jī)、挖掘機(jī)、裝載機(jī)等而言，其液壓缸在整個(gè)工作過(guò)程中負(fù)載方向始終維持不變。下面以起重機(jī)變幅液壓缸為例來(lái)探討雙閥芯的控制策略。?

　　?起重機(jī)變幅缸在工作過(guò)程中其受力，負(fù)載方向始終保持不變，因此我們可以采取液壓缸有桿控用壓力控制、無(wú)桿腔用流量控制的控制策略。?
