液壓系統(tǒng)已經(jīng)在冶金設(shè)備中廣泛應(yīng)用,特別是在帶鋼連軋機(jī)上采用電子計(jì)算機(jī)自動(dòng)控制的液壓壓下系統(tǒng),標(biāo)志著七十年代的先進(jìn)水平。因生產(chǎn)的迅速發(fā)展,就要求提高速度,嚴(yán)格控制精度,才能獲得優(yōu)質(zhì)高產(chǎn),這就促使液壓系統(tǒng)采用電液伺服機(jī)構(gòu),從而大幅度地提高了自動(dòng)控制程度。為了提高控制系統(tǒng)的反應(yīng)直線性和靈敏性,減小滑閥的間隙是主要的措施,因而要大幅度地提高元件的制造精度。以莫格(MOOG73型)電液伺服閥為例,其閥芯與閥套的間隙僅0.。。0050時(shí)(1 .225微米),直徑公差小于0.25微米,加工精度達(dá)到ISAI級(jí)精度。我國(guó)三機(jī)部609研究所生產(chǎn)的                 
潔凈度標(biāo)志著七十年代液壓技術(shù)的新水平。液壓油的潔凈度直接影響系統(tǒng)的運(yùn)行狀況。電液伺服系統(tǒng)要求液壓油的潔凈度最嚴(yán)格。潔凈度的級(jí)別用得最廣泛的是NAS和MOOG標(biāo)準(zhǔn)。潔凈度的檢測(cè)方法使用Millipore儀最普遍,分為計(jì)數(shù)法和重量法兩種。要絕對(duì)防止液壓油不被污染是不可能的,但通過(guò)人們的努力是可以控制污染的。文中分析了污染顆粒的來(lái)源,為了控制污染,提出了從設(shè)計(jì)上應(yīng)采取的措施,和設(shè)備安裝施工中應(yīng)采取的措施,以及在運(yùn)行操作中應(yīng)采取的一些措施,介紹了武鋼一米七軋機(jī)的一些經(jīng)驗(yàn)。
