如何區分常閉型日本SMC電磁閥和常開型日本SMC電磁閥
般日常所用日本SMC電磁閥分為常閉型和常開 型兩大種類,常閉型電磁閥指線圈沒通電時氣路是斷的,常開型電磁閥指線圈沒通電時氣路是通的。 常閉型電磁閥動作原理:給線圈通電,氣路接通,線圈旦斷電,氣路就會斷開,這相當于點動。 常開型電磁閥動作原理:給線圈通電,氣路斷開,線圈旦斷電,氣路就會接通,這也是點動。
通常根據持續工作時間長短來選擇:常閉、常開、或可持續通電
1、當日本SMC電磁閥需要長時間開啟,并且持續的時間多余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
