液壓系統(tǒng)電液伺服閥的選用

電液伺服閥由電氣一機(jī)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(jī)械轉(zhuǎn)換器是將電信號(hào)轉(zhuǎn)換成機(jī)械位移;液壓放大器是將電氣一機(jī)械轉(zhuǎn)換器輸出的機(jī)械位移放大后推動(dòng)閥芯運(yùn)動(dòng),液壓放大器由前置放大級(jí)和功率放大級(jí)組成,前置放大級(jí)采用滑閥、噴嘴擋闆閥或射流管閥,功率級(jí)采用滑閥形式。

電液伺服閥分爲(wèi)單級(jí)、二級(jí)和三級(jí)。單級(jí)電液伺服閥直接由力馬達(dá)或力矩馬達(dá)驅(qū)動(dòng)滑閥閥芯,用于壓力低于6. 3MPa、流量小于4L/min和負(fù)載變化小的系統(tǒng);二級(jí)電液伺服閥有兩級(jí)液壓放大器,用于流量小于200L/min的系統(tǒng);三級(jí)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(diǎn)和系統(tǒng)性能要求。伺服閥最大的弱點(diǎn)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(yīng)用在動(dòng)態(tài)精度和控制精度高、抗干擾能力強(qiáng)的閉環(huán)系統(tǒng)中,對(duì)動(dòng)態(tài)精度要求一般的液壓系統(tǒng)可用比例閥。

從響應(yīng)速度優(yōu)先的原則考慮,伺服閥的前置級(jí)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(yīng)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(qiáng),可延長(zhǎng)系統(tǒng)無故障工作時(shí)間;從性能穩(wěn)定方面考慮,射流管閥的磨蝕是對(duì)稱的,不會(huì)引起零漂,性能穩(wěn)定,壽命長(zhǎng);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(duì)系統(tǒng)響應(yīng)特性的影響,但不要過寬,否則系統(tǒng)抗干擾能力減??;伺服閥在安裝時(shí),閥芯應(yīng)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(gè)線圈,接法有單線圈、雙線圈,串聯(lián)、并聯(lián)和差動(dòng)等方式。使用時(shí)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(yùn)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(zhǎng)度、連接闆或 液壓系統(tǒng)執(zhí)行器的安裝形式消除;爲(wèi)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(hào)上疊加一個(gè)高頻低幅值的顫振信號(hào)。
