德國FESTO電(dian)(dian)磁(ci)閥(fa)(fa)其(qi)它(ta)(ta)種類執行(xing)器易于(yu)(yu)安(an)裝維護。更(geng)顯著的(de)是(shi)所組成的(de)自控系(xi)統簡單得(de)多(duo),價(jia)格要低(di)得(de)多(duo)。由于(yu)(yu)電(dian)(dian)磁(ci)閥(fa)(fa)是(shi)開(kai)關信號控制,與(yu)工控計算(suan)機連接十分方便。在當今電(dian)(dian)腦普及,價(jia)格大幅下降(jiang)的(de)時(shi)代(dai),電(dian)(dian)磁(ci)閥(fa)(fa)的(de)優勢(shi)就更(geng)加明(ming)顯。(3)動(dong)作(zuo)快遞,功率(lv)微(wei)小,外形(xing)輕(qing)巧。電(dian)(dian)磁(ci)閥(fa)(fa)響應(ying)時(shi)間(jian)可(ke)以(yi)短(duan)幾(ji)個(ge)毫(hao)秒(miao),即使是(shi)導式(shi)電(dian)(dian)磁(ci)閥(fa)(fa)也(ye)可(ke)以(yi)控制在幾(ji)十毫(hao)秒(miao)內(nei)。由于(yu)(yu)自成回路,比之其(qi)它(ta)(ta)自控閥(fa)(fa)反應(ying)更(geng)靈敏。設計得(de)當的(de)電(dian)(dian)磁(ci)閥(fa)(fa)線圈功率(lv)消耗很低(di),屬(shu)節能(neng)產品;還(huan)可(ke)做到(dao)只(zhi)(zhi)(zhi)需觸(chu)發動(dong)作(zuo),自動(dong)保持閥(fa)(fa)位,平(ping)時(shi)點也(ye)不(bu)(bu)耗電(dian)(dian)。電(dian)(dian)磁(ci)閥(fa)(fa)外形(xing)尺寸小,既節省空間(jian),又輕(qing)巧美(mei)觀。(4)調(diao)節精度(du)受(shou)限(xian)(xian),適(shi)用(yong)介(jie)(jie)質(zhi)受(shou)限(xian)(xian)。電(dian)(dian)磁(ci)閥(fa)(fa)通常只(zhi)(zhi)(zhi)有開(kai)關兩種狀(zhuang)態,閥(fa)(fa)芯只(zhi)(zhi)(zhi)能(neng)處于(yu)(yu)兩個(ge)極限(xian)(xian)位置,不(bu)(bu)能(neng)連續調(diao)節,(力圖突(tu)破的(de)新構思不(bu)(bu)少,但還(huan)都(dou)處于(yu)(yu)試驗試用(yong)階(jie)段)所以(yi)調(diao)節精度(du)還(huan)受(shou)到(dao)定(ding)限(xian)(xian)制。電(dian)(dian)磁(ci)閥(fa)(fa)對介(jie)(jie)質(zhi)潔凈度(du)有較高(gao)要求,含顆粒狀(zhuang)的(de)介(jie)(jie)質(zhi)不(bu)(bu)能(neng)適(shi)用(yong),如(ru)屬(shu)雜質(zhi)須濾去。另外,粘(zhan)(zhan)稠狀(zhuang)介(jie)(jie)質(zhi)不(bu)(bu)能(neng)適(shi)用(yong),而且,特定(ding)的(de)產品適(shi)用(yong)的(de)介(jie)(jie)質(zhi)粘(zhan)(zhan)度(du)范圍(wei)相對較窄。(5)型號多(duo)樣,用(yong)途(tu)廣泛。電(dian)(dian)磁(ci)閥(fa)(fa)雖有天不(bu)(bu)

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。
、FESTO電磁閥適用控制精度
a、動作時間:指電信號接通或切斷主閥動作完成時間,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,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。般來說交流電源取用方便。
b、電壓規格用盡量優選用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(huo)混合狀態分別(bie)選用不同品種(zhong)的電磁閥。
