人民電氣爲您介紹MQ1牽引電磁铁

2020/5/13 15:19:04      点击:
産品介紹

適用于50Hz電壓至380V的控制線路中,作爲機械設備及自動化系統的各種操作機構的遠距離控制之用。

電磁鐵在下列條件下能可靠的工作:
(1)海拔高度不超過2500米;周圍介質溫度不高于+40℃及不低于一25℃;
(2)最濕月的月平均最大相對濕度爲90%.同時該月的月平均最低溫度爲+25℃,並考慮到因溫度變化發生在産品表面上的凝露;
(3)無顯著搖動和中擊振動的地方;
(4)在無爆炸危險的介質中。且介質中無足以腐蝕金屬和破壞絕緣的氣體及塵埃(包括導電塵埃);
(5)無雨雪侵襲的地方。

結構原理
電磁鐵系交流單相螺管式無罩結構,分拉動式和推動式兩種(拉動式用N表示,推動式用Z表示),線圈斷電後無複位裝置。電磁鐵是由磁轭和銜鐵兩部分組成。在使用時將磁轭安裝在固定支架上,而將銜鐵活動地連接在牽引杆上,當吸引線圈通過電時銜鐵活動地連接在牽引杆上,當吸引線圈通過電時銜鐵被吸合,經過連杆帶動其所控制的機構。
