DMF-2L-B電(dian)(dian)磁(ci)(ci)脈(mo)沖(chong)閥(fa)開啟電(dian)(dian)壓(ya)試(shi)驗：在(zai)電(dian)(dian)磁(ci)(ci)脈(mo)沖(chong)閥(fa)的(de)(de)進氣口(kou)接入(ru)氣源壓(ya)力為(wei)(wei)標稱(cheng)壓(ya)力的(de)(de)潔凈空氣，在(zai)電(dian)(dian)磁(ci)(ci)閥(fa)上輸入(ru)標稱(cheng)電(dian)(dian)壓(ya)的(de)(de)85%，寬度為(wei)(wei)0.03s的(de)(de)電(dian)(dian)信號(hao)，檢查(cha)電(dian)(dian)磁(ci)(ci)脈(mo)沖(chong)閥(fa)開啟是(shi)否正(zheng)常(chang)。

DMF-2L-B電(dian)磁脈(mo)沖閥(fa)抗振動(dong)(dong)試(shi)驗(yan)：將閥(fa)固定在振動(dong)(dong)試(shi)驗(yan)工作臺上，承受振動(dong)(dong)頻率為20Hz、全(quan)幅值為2mm、歷時30min的(de)振動(dong)(dong)后，檢查閥(fa)各部(bu)分的(de)緊(jin)固件是(shi)否有(you)松動(dong)(dong)現象，工作是(shi)否正常。

膜片把(ba)DMF-2L-B電(dian)磁脈(mo)沖(chong)閥(fa)分成(cheng)前、后(hou)(hou)二個氣(qi)室(shi)，當接通壓縮空氣(qi)通過節流孔(kong)進入(ru)后(hou)(hou)天室(shi)，此時后(hou)(hou)氣(qi)室(shi)壓力(li)將膜片緊貼(tie)閥(fa)的(de)輸出口，電(dian)磁脈(mo)沖(chong)閥(fa)處于“關閉”狀態。脈(mo)沖(chong)噴吹控制儀(yi)電(dian)信號消失，電(dian)磁脈(mo)沖(chong)閥(fa)銜鐵復位(wei)，后(hou)(hou)氣(qi)室(shi)放氣(qi)孔(kong)關閉，后(hou)(hou)氣(qi)室(shi)壓力(li)升高(gao)使(shi)膜片緊貼(tie)閥(fa)出口，電(dian)磁脈(mo)沖(chong)閥(fa)又處于“關閉”狀態。
