液壓系統(tǒng)設計時為提高系統(tǒng)穩(wěn)定性，減少負載變化對速度的影響，要么犧牲部分我們想實現的功能，要么增加額外的液壓元件，如調速閥、壓力控制閥等，通過增加阻尼，提高系統(tǒng)速度剛度來提高系統(tǒng)的穩(wěn)定性。但是這樣元件的增加又會降低效率，浪費能源；還會使得整個系統(tǒng)的可靠性降低、增加成本。?

　　?（2）由于換向結構的特殊性，使得用戶在實現某一功能時必須購買相應的液壓元件，再加上工程機械廠家會根據不同最終用戶要求設計出相應的功能，這樣會造成生產廠家采購同類、多規(guī)格的液壓控制元件來滿足不同功能要求的需要，不利于產品通用化及產品管理，同時會大大提高產品成本。?

　　?（3）由于執(zhí)行機構進出液壓油通過一根閥芯進行控制，單獨控制執(zhí)行機構兩側壓力是不可能的。因此，出油側背壓作用于執(zhí)行機構運動的反方向，隨著出油側背壓升高，為保質執(zhí)行機構的運動，必須提高進油側壓力。這樣會使得液壓系統(tǒng)消耗的功能增加，效率低，發(fā)熱增加。?

　　?采用雙閥芯技術的液壓系統(tǒng)，由于執(zhí)行機構進出油側閥口閥芯位置及控制方式各自獨立，互不影響，這樣通過對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)不能解決的問題，同時還可以輕易實現傳統(tǒng)液壓系統(tǒng)中難以實現的功能。?

2、雙閥芯換向閥的兩種基本控制策略?

　　?由于雙閥芯換向兩油口控制的靈活性，兩油口可分別采取流量控制、壓力控制或流量壓力控制。正面介紹兩種簡單的控制策略。?

（1）負載方向在整個工作過程中保持不變?

　　?我們知道，對于汽車起重機、挖掘機、裝載機等而言，其液壓缸在整個工作過程中負載方向始終維持不變。下面以起重機變幅液壓缸為例來探討雙閥芯的控制策略。?

　　?起重機變幅缸在工作過程中其受力，負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、無桿腔用流量控制的控制策略。?

　　?無桿腔流量控制是通過檢測連接到無桿腔側閥前后兩側的壓差，再根據所需流入或流出流量的多少，計算出閥芯開口大??；有桿腔側采用壓力控制，使該側維持一個低值的壓力，使得更加節(jié)能、高效。?

　　?由于我們在無桿腔采用了流量控制，因此原控制系統(tǒng)中所用的平衡閥可用一個液控單向閥來代替。這樣可消除因平衡閥所帶來的系統(tǒng)不穩(wěn)定，從而提高系統(tǒng)穩(wěn)定性。?
