一、LY標準液下泵概述
LY/LYO/LYG系列長軸液下泵，選用國際優秀的水力模型，泵設計和制造按AP1610VS4型執行，泵軸由泵蓋和滑動軸承體內的滑動軸承支承，上軸承采用耐磨軸承，采用鋰基潤滑脂潤滑。該系列泵適用于輸送各種腐蝕性液體和清水，同時也適用于輸送含有顆粒或纖維的各類污水。LY/LYO型其輸送介質溫度范圍為-20℃~+120℃，LYG型輸送介質可達+400℃，工作壓力可達1.6MPa。
二、LY化工液下泵結構特點
LY型長軸液下泵接軸結構安全可靠
轉子部件可以軸向調整
轉子部件采用多點支撐，泵運轉安全可靠。
滑動軸承采用外潤滑或自潤滑
泵起動時，葉輪已浸沒在介質中，因而起動容易，不存在排氣抽空問題
采用雙端蝸殼泵體（口徑80mm上），轉子部件受徑力小，軸撓度小，滑動軸承磨損小，壽命長。
從電機端看，泵為順時針方向旋轉。
三、LY長軸液下泵型號意義
LY40-160
LY--長軸液下化工泵
40--出口直徑mm
160--葉輪名義直徑mm
