產品簡介
上海益博機電設備有限公司供應SMC電磁閥SYJ5120-5LZD-M5。不同的電磁閥在控制系統的不同位置 發揮作用,Z常用的是單向閥,安全閥,方向控制閥,速度調節閥 等.電磁閥是用電磁的效應進行控制,主要的控制方式由繼電器控 制.這樣,電磁閥可以配合不同的電路來實現預期的控制,而控制 的精度和靈活性都能夠保證。
詳細介紹
SMC電磁閥 日本SMC SYJ5120-5LZD-M5 SMC上海 現貨SMC SMC總 SMC電磁閥* 電磁閥的結構原理 一:直動式電磁閥有常閉型和常開型二種.常閉型斷電時呈關閉狀態,當線圈通電時 產生電磁力,使動鐵芯克服彈簧力同靜鐵芯吸合直接開啟閥,介質 呈通路; 當線圈斷電時電磁力消失, 動鐵芯在彈簧力的作用下復位, 直接關閉SMC電磁閥有什么作用之處，閥口,介質不通.結構簡單,動作可靠,在零壓差和微真 空下正常工作. 常開型正好相反. 如小于 φ6 流量通徑的電磁閥. （圖 一是典型結構圖）
二,分步直動式電磁閥該閥采用一次開閥和二次開閥連在一體,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 芯連在一起,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.（圖二是 典型結構圖）
三,間接先導式電磁閥 該系列電磁閥由先導閥和主閥芯著形成通道組合而成;常閉型 在未通電時,呈關閉狀態.當線圈通電時,產生的磁力使動鐵芯和 靜鐵芯吸合,導閥口打開,介質流向出口,此時主閥芯上腔壓力減 少,低于進口側的壓力,形成壓差克服彈簧阻力而隨之向上運動, 達到開啟主閥口的目的,介質流通.當線圈斷電時,磁力消失,動 鐵芯在彈簧力作用下復位關閉先導口,此時介質從平衡孔流入,主 閥芯上腔壓力增大,并在彈簧力的作用下向下運動,關閉主閥口. 常開式原理正好相反.如:SLA,DF（φ15 以上口徑）,ZCZ 等. （圖三是典型結構圖） 電磁閥的選型 一:適用性 管路中的流體必須和選用的電磁閥系列型號中標定的介質*. 流體的溫度必須小于選用電磁閥的標定溫度. 電磁閥允許液體粘度一般在 20CST 以下,大于 20CST 應注明. 工作壓差,管路zui高壓差在小于 0.04MPa 時應選用如 ZS,2W,ZQDF,ZCM 系列等直動式和分步直動式; zui低工作壓差大于 0.04MPa 時 可選用先導式（壓差式）電磁閥;zui高工作壓差應 小于電磁閥的zui大標定壓力;一般電磁閥都是單向工作,因此要注 意是否有反壓差,如有安裝止回閥. 流體清潔度不高時應在電磁閥前安裝過濾器,一般電磁 閥對介質要求清潔度要好. 注意流量孔徑和接管口徑;電磁閥一般只有開關兩位控制;條件允 許請安裝旁路管,便于維修;有水錘現象時要定制電磁閥的開閉時 間調節. 注意環境溫度對電磁閥的影響 電源電流和消耗功率應根據輸出容量選取,電源電壓一般允許 ±10%左右,必須注意交流起動時 VA 值較高. 二,可靠性 電磁閥分為常閉和常開二種;一般選用常閉型,通電打開,斷電關 閉;但在開啟時間很長關閉時很短時要選用常開型了. 壽命試驗,工廠一般屬于型式試驗項目,確切地說我國還沒有電磁 閥的專業標準,因此選用電磁閥廠家時慎重. 動作時間很短頻率較高時一般選取直動式,大口徑選用快速系列. 三,安全性 一般電磁閥不防水, 在條件不允許時請選用防水型, 工廠可以定做. 電磁閥的zui高標定公稱壓力一定要超過管路內的zui高壓力,否則使 用壽命會縮短或產生其它意外情況. 有腐蝕性液體的應選用全不銹鋼型,強腐蝕性流體宜選用塑料王 （SLF）電磁閥. 爆炸性環境必須選用相應的防爆產品. 四,經濟性 有很多電磁閥可以通用,但在能滿足以上三點的基礎上應選用zui經 濟的產品VF3240-5DZB-02
