? 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。?
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(jì)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(gè)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(gè)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。?
(2)負(fù)載方向在工作過程中發(fā)生改變?
在這種情況下,采取“進(jìn)油側(cè)壓力控制,出油側(cè)流量控制”,在液壓缸有桿腔側(cè)用壓力控制,無桿腔側(cè)有流量控制。?
如負(fù)載方向不變,由于出油側(cè)采取了流量控制,我們可將雙向平衡閥用液控單向閥來替換,從而提高系統(tǒng)的穩(wěn)定性。進(jìn)油側(cè)用壓力控制器來維持一個(gè)較低的參考?jí)毫Γ环矫嫣岣呦到y(tǒng)效率,另一方面使系統(tǒng)不發(fā)生氣穴。?電磁換向閥DG4V-5-6C-M-U-A6-20

為了使負(fù)載方向變化的工作機(jī)構(gòu)能得到很好控制,另外一個(gè)PI控制器將被運(yùn)用到有桿腔的壓力控制器中,當(dāng)負(fù)載方向改變后,無桿腔的壓力將減??;如果仍將有桿腔維持一個(gè)很低的壓力,當(dāng)負(fù)載很大時(shí),液壓缸將向反方向運(yùn)動(dòng)。此時(shí)我們可用所增加的PI控制器監(jiān)視無桿腔壓力的變化,當(dāng)PI控制器檢測到無桿腔壓力低于所設(shè)定的參考值時(shí),將提高有桿腔壓力控制器所設(shè)定的壓力,從而保證系統(tǒng)的正常工作。?
