SMC電磁閥VXP2142-04-3DZ的注意事項(xiàng)

性能介紹：

SMC電磁閥輸出軸轉(zhuǎn)動(dòng)圈數(shù)電動(dòng)閥門裝置輸出

必須采取各種組合方式，歸納起來(lái)有兩種：一

是對(duì)電機(jī)輸入電流的增減進(jìn)行判斷；二是對(duì)電

軸轉(zhuǎn)動(dòng)圈數(shù)的多少與閥門的公稱通徑、閥桿螺

距、螺紋頭數(shù)有關(guān)，要按M＝H／ZS計(jì)算（M

頭數(shù)）。過(guò)去對(duì)SMC電磁閥進(jìn)行保護(hù)的辦法是

使用熔斷器、過(guò)流繼電器、熱繼電器、恒溫器

為電動(dòng)裝置應(yīng)滿足的總轉(zhuǎn)動(dòng)圈數(shù)，H為閥門開(kāi)

啟高度，S為閥桿傳動(dòng)螺紋螺距，Z為閥桿螺紋

等，但這些辦法各有利弊。對(duì)電動(dòng)裝置這種變

負(fù)荷設(shè)備，的保護(hù)辦法是沒(méi)有的。因此，

機(jī)本身發(fā)熱情況進(jìn)行判斷。這兩種方式，無(wú)論

那種都要考慮電機(jī)熱容量給定的時(shí)間余量。

清洗法：

SMC電磁閥管路中的焊渣、鐵銹、渣子等在節(jié)

流口、導(dǎo)向部位、下閥蓋平衡孔內(nèi)造成堵塞或

受到損傷還應(yīng)研磨；同時(shí)將底塞打開(kāi)，以沖掉

從平衡孔掉入下閥蓋內(nèi)的渣物，并對(duì)管路進(jìn)行

卡住使閥芯曲面、導(dǎo)向面產(chǎn)生拉傷和劃痕、密

和大修后投運(yùn)初期。這是常見(jiàn)的故障。遇此情

況，必須卸開(kāi)進(jìn)行清洗，除掉渣物，如密封面

封面上產(chǎn)生壓痕等。這經(jīng)常發(fā)生于新投運(yùn)系統(tǒng)

沖洗。投運(yùn)前，讓調(diào)節(jié)閥全開(kāi)，介質(zhì)流動(dòng)一段

時(shí)間后再納入正常運(yùn)行。
