選型中文說明書:
1、根據管道參數選擇電磁閥的:通徑規格(即DN)、接口方式1)按照現場管道內徑尺寸或流量要求來確定通徑(DN)尺寸;2)接口方式,一般>DN50要選擇法蘭接口,≤DN50則可根據用戶需要自由選擇。
2、根據流體參數選擇電磁閥的:材質、溫度組1)腐蝕性流體:宜選用耐腐蝕電磁閥和全不銹鋼;食用超凈流體:宜選用食品級不銹鋼材質電磁閥;2)高溫流體:要選擇采用耐高溫的電工材料和密封材料制造的電磁閥,而且要選擇活塞式結構類型的;3)流體狀態:大至有氣態,液態或混合狀態,特別是口徑大于DN25時一定要區分開來;4)流體粘度:通常在50cSt以下可任意選擇,若超過此值,則要選用高粘度電磁閥。
3、根據壓力參數選擇電磁閥的:原理和結構品種1)公稱壓力:這個參數與其它通用閥門的含義是一樣的,是根據管道公稱壓力來定;2)工作壓力:如果工作壓力低則必須選用直動或分步直動式原理;低工作壓差在0.04Mpa以上時直動式、分步直動式、先導式均可選用。
4、電氣選擇:電壓規格應盡量優先選用AC220V、DC24較為方便。
5、根據持續工作時間長短來選擇:常閉、常開、或可持續通電1)當電磁閥需要長時間開啟,并且持續的時間多于關閉的時間應選 用常開型;2)要是開啟的時間短或開和關的時間不多時,則選常閉型;3)但是有些用于安全保護的工況,如爐、窯火焰監測,則不能選常開的,應選可長期通電型。
6、根據環(huan)境要(yao)求選擇輔助(zhu)功(gong)能:防爆(bao)、止回、手動、防水霧、水淋、潛水。
