A10VSO...DFE1變量泵的壓力和斜盤傾角的閉環(huán)控制是通過一個(gè)電控比例閥(2) 實(shí)現(xiàn)的。該比例閥通過控制活塞(4)決定斜盤(1)的位置。泵的排量與斜盤的位置成比例??刂苹y(3)由彈簧(5)進(jìn)行預(yù)壓緊,并始終受泵壓力的作用。當(dāng)泵不工作,及控制系統(tǒng)的壓力為零時(shí),由于彈簧(5)的作用,斜盤保持在+*的位置。當(dāng)泵啟動(dòng)后如比例電磁閥(8)失電,該系統(tǒng)被切換到零行程壓力,此時(shí)滑閥(9)被彈簧(10)推到初始位置,這時(shí)泵的壓力p經(jīng)過閥口A作用到控制活塞(4)上。調(diào)節(jié)滑閥上的泵壓與彈簧(5)的作用力相平衡,使泵的壓力在8到12bar之間。這個(gè)基本設(shè)定是在閉環(huán)控制電路不工作時(shí)實(shí)現(xiàn)的(=零行程工作)(例如控制不啟動(dòng))。該比例閥的控制由由系統(tǒng)的VT5041-2X控制板承擔(dān)。所有用來控制變量泵A10VSO...DFE1所需的信號(hào)都由該控制板來處理。VT5041-2X模擬放大器屬于歐洲制式的插板式。它是標(biāo)準(zhǔn)的,分別對(duì)壓力和斜盤傾角的指令值進(jìn)行輸入(功率設(shè)定值的輸入為可選項(xiàng))。壓力的實(shí)際值通過一個(gè)壓力傳感器采樣。裝在泵上的一個(gè)位移傳感器提供泵斜盤傾角的實(shí)際值。得到的實(shí)際值經(jīng)放大器處理并與指令值進(jìn)行比較。zui小信號(hào)發(fā)生器自動(dòng)確保被選中的控制器只有在需要的工作點(diǎn)起作用。
因此系統(tǒng)參數(shù)(壓力、傾角或功率(可選))可被精確控制,而其他兩個(gè)參數(shù)低於給定的指令值。zui小信號(hào)發(fā)生器的輸出信號(hào)作為閥閉環(huán)控制電路的指令值?;y閥芯實(shí)際位置由一個(gè)感應(yīng)式傳感器(6)提供。閥位置控制器的輸出值經(jīng)放大器的輸出端輸出,決定比例電磁鐵(8)的電流。一旦到達(dá)工作點(diǎn),比例閥閥芯(9)就被保持在中間位置。如果上級(jí)控制器需要增大傾角(增大流量),閥芯(9)需偏離中間位置(使控制活塞(4)通過閥口A→T),直到傾角達(dá)到需要的值。通過增大比例電磁鐵(8)的電流來克服彈簧
(10)的作用力使得閥芯移動(dòng)。當(dāng)需要減小傾角時(shí),控制活塞(4)的通道為P→A。
控制系統(tǒng)壓力油的提供
有三種方法提供泵的液壓控制系統(tǒng)的先導(dǎo)控制油液:
1. 內(nèi)部提供,預(yù)增壓閥(僅適用於壓力大於20 bar 的系統(tǒng))
2. 內(nèi)部提供,帶預(yù)增壓閥(系統(tǒng)壓力的0...100 %)
3.通過一個(gè)梭閥遠(yuǎn)程供油-通過一個(gè)梭閥連接塊可進(jìn)行內(nèi)部/外部
