FESTO電磁閥工作壓力調節,德國費斯托電磁閥

FESTO電磁閥動作時間：指電信號接通或切斷至主閥動作完成時間，只有本公司產品多功能電磁閥可對開啟和關閉時間分別調節，不僅可滿足控制精度要求，還可防止水錘破壞。b、普通電磁閥只有開、關兩個位置，在控制精度要求高和參數要求平穩時請選用多位電磁閥。 c、泄漏量樣本上給出的泄漏量數值為常用經濟等級，若嫌偏高，請作特殊訂貨。 二、適用電源 a、根據供電電源種類，分別選用交流和直流電磁閥。一般來說交流電源取用方便。 b、電壓規格用盡量優先選用AC220V.DC24V。 c、電源電壓波動通常交流選用+%10%.-15%，直流允許±%10左右，如若超差，須采取穩壓措施或提出特殊訂貨。 d、應根據電源容量選擇額定電流和消耗功率。須注意交流起動時VA值較高，在容量不足時應優先選用間接導式電磁閥。 三、適用環境 a、環境的zui高和zui低溫度應選在允許范圍之內，如有超差需作特殊訂貨提出。 b、環境中相對濕度高及有水滴雨淋等場合，應選防水電磁閥。 c、環境中經常有振動，顛簸和沖擊等場合應選特殊品種，例如船用電磁閥。 d、在有腐蝕性或爆炸性環境中的使用應優先根據安全性要求選用耐發蝕。 e、環境空間若受限制，請選用多功能電磁閥，因其省去了旁路及三只手動閥且便于在線維修。適用介質： 1、氣液態或混合狀態分別選用不同品種的電磁閥。 2、介質溫度不同規格產品，否則線圈會燒掉，密封件老化，嚴重影響壽命。介質溫度應選在電磁閥允許范圍之內。 3、介質粘度，通常在50cSt以下。若超過此值，通徑小于15mm訂高粘度電磁閥。4、介質清潔度不高時都應在電磁閥前配裝反沖過濾閥。介質若是定向流通，且不允許倒流。 四、適用管道： a、根據介質流向要求及管道連接方式選擇閥門通口及型號。 b、根據流量和閥門Kv值選定公稱通徑，也可選同管道內徑。 c、工作壓差zui低工作壓差在0.04Mpa以上是可選用間接先導式；zui低工作壓差接近或小于零的必須選用直動式或分步直接式。
