日本SMC電磁閥在運行的時候要*那幾個參數

日本SMC電磁閥在運行的時候要*那幾個參數
電磁閥本身結構簡單，價格也低，比起調節閥等其它種類執行器易于安裝維護。更顯著的是所組成的自控系統簡單得多，價格要低得多。
日本SMC電磁閥是開關信號控制，與工控計算機連接十分方便。在當今電腦普及，價格大幅下降的時代，電磁閥的優勢就更加明顯。SMC電磁閥動作快遞，功率微小，外形輕巧。
日本SMC電磁閥響應時間可以短幾個毫秒，即使是導式電磁閥也可以控制在幾十毫秒內。由于自成回路，比之其它自控閥反應更靈敏。
日本SMC電磁閥線圈功率消耗很低，屬節能產品；還可做到只需觸發動作，自動保持閥位，平時點也不耗電。電磁閥外形尺寸小，既節省空間，又輕巧美觀。電磁閥調節精度受限，適用介質受限。
日本SMC電磁閥通常只有開關兩種狀態，閥芯只能處于兩個極限位置，不能連續調節，（力圖突破的新構思不少，但還都處于試驗試用階段）所以調節精度還受到定限制。
日本SMC電磁閥對介質潔凈度有較高要求，含顆粒狀的介質不能適用，如屬雜質須濾去。另外，粘稠狀介質不能適用，而且，特定的產品適用的介質粘度范圍相對較窄。
日本SMC電磁閥型號多樣，用途廣泛。電磁閥雖有天不足，優點仍十分突出，所以就設計成多種多樣的產品，滿足各種不同的需求，用途極為廣泛。
日本SMC電磁閥該閥采用次開閥和二次開閥連在體,主閥和導閥分步使電磁力 和壓差直接開啟主閥口. 當線圈通電時, 產生電磁力使動鐵芯 和 靜鐵芯吸合,導閥口開啟而導閥口設在主閥口上,且動鐵芯與主閥 芯連在起,此時主閥上腔的壓力通過導閥口卸荷,在壓力差和電 磁力的同時作用下使主閥芯向上運動,開啟主閥介質流通.當線圈 斷電時電磁力消失,此時動鐵芯在自重和彈簧力的作用下關閉導閥 孔,此時介質在平衡孔中進入主閥芯上腔,使上腔壓力升高,此時 在彈簧復位和壓力的作用下關閉主閥,介質斷流.結構合理,動作 可靠,在零壓差時工作也可靠.如:ZQDF,ZS,2W 等.
