M-3SEW6X3C/420MG24N9K4　 我們知道，對于汽車起重機(jī)、挖掘機(jī)、裝載機(jī)等而言，其液壓缸在整個工作過程中負(fù)載方向始終維持不變。下面以起重機(jī)變幅液壓缸為例來探討雙閥芯的控制策略。 M-3SED6UK1X/350CG24N9K4?

　　 起重機(jī)變幅缸在工作過程中其受力，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(cè)閥前后兩側(cè)的壓差，再根據(jù)所需流入或流出流量的多少，計算出閥芯開口大??；有桿腔側(cè)采用壓力控制，使該側(cè)維持一個低值的壓力，使得更加節(jié)能、高效。 4WE6D62/EG24N9K4,4WE6D62/EG24N9K4/V,4WE6D62/EW230N9K4,4WE6D6X/OFEG24N9K4,4WE6D6X/OFEG24N9K4,

　　 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。?
