液壓系統(tǒng)電液伺服閥的選用
電液伺服閥由電氣一機械轉(zhuǎn)換器和液壓系統(tǒng)放大器構(gòu)成,如圖1所示。電氣一機械轉(zhuǎn)換器是將電信號轉(zhuǎn)換成機械位移;液壓放大器是將電氣一機械轉(zhuǎn)換器輸出的機械位移放大后推動閥芯運動,液壓放大器由前置放大級和功率放大級組成,前置放大級采用滑閥、噴嘴擋闆閥或射流管閥,功率級采用滑閥形式。
電液伺服閥分爲單級、二級和三級。單級電液伺服閥直接由力馬達或力矩馬達驅(qū)動滑閥閥芯,用于壓力低于6. 3MPa、流量小于4L/min和負載變化小的系統(tǒng);二級電液伺服閥有兩級液壓放大器,用于流量小于200L/min的系統(tǒng);三級電液伺服閥可輸出更大的流量和功率。
選用伺服閥要依據(jù)伺服閥的特點和系統(tǒng)性能要求。伺服閥最大的弱點是抗污染能力差,過濾器的顆粒粒度必須小于3um。伺服閥側(cè)重應用在動態(tài)精度和控制精度高、抗干擾能力強的閉環(huán)系統(tǒng)中,對動態(tài)精度要求一般的液壓系統(tǒng)可用比例閥。
從響應速度優(yōu)先的原則考慮,伺服閥的前置級優(yōu)先選擇噴嘴擋闆閥,其次是射流管閥,最后是滑閥;從功率考慮,應首先選擇射流管閥壓力效率和容積效率在70%以上,然后選擇滑閥和噴嘴擋闆閥;從抗污染和可靠性方面考慮,射流管閥的通徑大,抗污染能力強,可延長系統(tǒng)無故障工作時間;從性能穩(wěn)定方面考慮,射流管閥的磨蝕是對稱的,不會引起零漂,性能穩(wěn)定,壽命長;滑閥的開口形式一般選擇零開口結(jié)構(gòu);伺服閥規(guī)格由系統(tǒng)的功率和流量決定,并留有15%~30%的流量裕度;伺服閥的頻寬按照伺服系統(tǒng)頻寬的5倍選擇,以減少對系統(tǒng)響應特性的影響,但不要過寬,否則系統(tǒng)抗干擾能力減?。凰欧y在安裝時,閥芯應處于水平位置,管路采用鋼管連接,安裝位置盡可能靠近執(zhí)行器;伺服閥有2個線圈,接法有單線圈、雙線圈,串聯(lián)、并聯(lián)和差動等方式。使用時要注意;伺服閥正式安裝前,管路要接入精密過濾器,用60℃的工作油運行清洗lh;伺服閥若在使用中出現(xiàn)振蕩現(xiàn)象,可通過改變管路的長度、連接闆或 液壓系統(tǒng)執(zhí)行器的安裝形式消除;爲了減小和消除伺服閥閥芯與閥套的間隙,防止滑閥卡死或堵塞,在伺服閥輸入信號上疊加一個高頻低幅值的顫振信號。
