性能介紹:
SMC電磁閥輸出軸轉動(dòng)圈數電動(dòng)閥門(mén)裝置輸出
必須采取各種組合方式,歸納起來(lái)有兩種:一
是對電機輸入電流的增減進(jìn)行判斷;二是對電
軸轉動(dòng)圈數的多少與閥門(mén)的公稱(chēng)通徑、閥桿螺
距、螺紋頭數有關(guān),要按M=H/ZS計算(M
頭數)。過(guò)去對SMC電磁閥進(jìn)行保護的辦法是
使用熔斷器、過(guò)流繼電器、熱繼電器、恒溫器
為電動(dòng)裝置應滿(mǎn)足的總轉動(dòng)圈數,H為閥門(mén)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。對電動(dòng)裝置這種變
負荷設備,的保護辦法是沒(méi)有的。因此,
機本身發(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
流口、導向部位、下閥蓋平衡孔內造成堵塞或
受到損傷還應研磨;同時(shí)將底塞打開(kāi),以沖掉
從平衡孔掉入下閥蓋內的渣物,并對管路進(jìn)行
卡住使閥芯曲面、導向面產(chǎn)生拉傷和劃痕、密
和大修后投運初期。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)生于新投運系統
沖洗。投運前,讓調節閥全開(kāi),介質(zhì)流動(dòng)一段
時(shí)間后再納入正常運行。
