LG、LG-B型-多級立式不銹鋼礦用多級離心泵簡介
上海長征泵閥生產(chǎn)的LG、LG-B型立式多級離心泵。該型泵由于采用了高效節(jié)能的優(yōu)秀水力模型,因此具有效率高,性能范圍廣的優(yōu)點,更好地滿足了用戶的使用要求。另外,LG、LG-B型在結(jié)構(gòu)上采用了立式、分段形式,且運轉(zhuǎn)安全、平穩(wěn)、壽命長、占地面積小,安裝維修方便。
 
	LG、LG-B型-多級立式不銹鋼礦用多級離心泵特點 
1、結(jié)構(gòu)緊湊、體積小、占地面積少。
2、更換易損件(機械密封)方便,即“便拆”不需拆電機。
3、裝配無需調(diào)整,拆檢維修方便。
4、徑向力、軸向力采用水力平衡,軸承承受相結(jié)合。
5、噪聲、振動小,運轉(zhuǎn)平穩(wěn)。
6、主要磨損件采用優(yōu)質(zhì)耐磨材料制造。
7、可配裝同型號的普通電機。
8、機械密封特殊設(shè)計,密封性好,壽命增強。
9、采用熱水型專用機械密封,可抽送熱水
LG、LG-B型-多級立式不銹鋼礦用多級離心泵用途
 該型泵特別適用于高低層建筑的住宅、醫(yī)院、旅館、百貨大樓、辦公大樓等的給排水及消防用水、噴淋、遠距離輸送及生產(chǎn)工藝循環(huán)中用水等用作循環(huán)水泵。
