style="text-indent:25px">氣動(dòng)閥門(mén)現(xiàn)在在各行業(yè)中應(yīng)用越來(lái)越多，氣動(dòng)執(zhí)行器的技術(shù)也在越來(lái)越好，國(guó)產(chǎn)氣動(dòng)執(zhí)行器與進(jìn)口氣動(dòng)執(zhí)行器的差距也越來(lái)越小，種類(lèi)也越來(lái)越多。無(wú)錫凱爾利為您介紹氣動(dòng)執(zhí)行器的幾種檢驗(yàn)方法：1 將氣動(dòng)執(zhí)行器固定于校驗(yàn)臺(tái)上，分別接好氣源、控制氣源和位移檢測(cè)連桿；將校驗(yàn)臺(tái)上儀表調(diào)校準(zhǔn)確；機(jī)械零點(diǎn)校準(zhǔn)：輸入4mA電流信號(hào)（0%），控制氣信號(hào)應(yīng)為0.02Mpa，此時(shí)氣缸活塞行程應(yīng)為零；如果不為零，可通過(guò)調(diào)整調(diào)零螺桿上的螺帽調(diào)整零點(diǎn)（零點(diǎn)高了緊螺帽）；零點(diǎn)和量程需要反復(fù)調(diào)整；零點(diǎn)誤差要≤1%。</p><p
