檢查氣包壓力是否過(guò)低 Check whether the air tank pressure is too low |
排查漏氣Check and prevent air leakage |
某些閥不工作,其他閥正常 Some valves cannot run while others can |
檢查閥的線(xiàn)路連接及線(xiàn)圈Check the line connections and sole-noids of the valves |
更換配件 Replace relevant parts |
|
所有閥無(wú)法關(guān)閉,有漏氣,氣包壓力無(wú)法建立Not all the valves can be closed;there is air leakage; the air tank pressure cannot be established |
閥的進(jìn)氣口與噴吹口相反安裝The air inlets and air outlets of the valves are reversely Installed |
重新安裝 Install the valves again |
|
某些閥無(wú)法關(guān)閉,有漏氣Some valves cannot be closed, there is air leakage |
有雜質(zhì)吸附在膜片上,動(dòng)鐵芯有卡死現象 There are foreign matters on the diaphragms; the armatures are seized |
清潔膜片,檢查膜片是否完整,檢查動(dòng)鐵芯及氣塞 Clean the diaphragms and check whether they are complete; check the armatures and the air plugs |
