膠閥滴漏此種情形經(jīng)常發(fā)生予膠閥關(guān)畢以后. 95%的此種情形是因?yàn)槭褂玫尼橆^口徑太小所致. 太小的針頭會(huì)影響液體的流動(dòng)造成背壓, 結(jié)果導(dǎo)致膠閥關(guān)畢后不久形成滴漏的現(xiàn)象. 過小的針頭也會(huì)影響膠閥開始使用時(shí)的排氣泡動(dòng)作.可以調(diào)節(jié)壓力桶氣壓，不要過高，能驅(qū)動(dòng)膠水即可，點(diǎn)膠閥能微調(diào)，就盡量調(diào)?。p少點(diǎn)膠閥反應(yīng)時(shí)間快），或者更換較大的針頭即可解決這種問題. 錐形斜式針頭產(chǎn)生的背壓**少, 液體流動(dòng)**順暢. 液體內(nèi)空氣在膠閥關(guān)畢后會(huì)產(chǎn)生滴漏現(xiàn)象, 比較好是預(yù)先排除液體內(nèi)空氣, 或改用不容易含氣泡的膠.或先將膠離心脫泡后在使用. 2. 出膠大小不一致當(dāng)出膠不一致時(shí)主要為儲(chǔ)存流體的壓力筒或空氣壓力不穩(wěn)定所產(chǎn)生. 進(jìn)氣壓力調(diào)壓表應(yīng)設(shè)定于比廠內(nèi)比較低壓力低10至15psi. </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河源點(diǎn)膠閥源頭直供"
