簡(jiǎn)化液壓系統(tǒng)結(jié)構(gòu),提倡“簡(jiǎn)而美”的設(shè)計(jì)原則,如減少零部件數(shù)目,這樣既便于裝配、拆卸,又便于廢棄后的分類處理;采用模塊化設(shè)計(jì),此時(shí)產(chǎn)品是由各功能模塊組成,既有利于產(chǎn)品的裝配、拆卸,又便于廢棄后的回收處理。

液壓閥的全面性能指標(biāo)包括很多,除有些項(xiàng)目安裝前只需核對(duì)產(chǎn)品的檢定、測(cè)試證書外,還要對(duì)其相關(guān)參數(shù)進(jìn)行重點(diǎn)檢測(cè)和調(diào)校。首先是液壓閥的基本誤差,將 20~10kPa的輸入信號(hào)平衡增大或減少地輸入執(zhí)行機(jī)構(gòu)的氣室內(nèi),測(cè)量各點(diǎn)所對(duì)應(yīng)的行程值,計(jì)算出:“信號(hào)-行程”關(guān)系與理論值之間的各點(diǎn)誤差,其大值即為基本誤差。
