一、LY長軸液下泵概述
LY型長軸液下泵是一種立式離心泵，適用于化工﹑石油﹑電力﹑冶金﹑制藥﹑造紙﹑環保等多個行業部門，可用來進行對有腐蝕性液體，含有一定量固體顆粒液體的輸送。是我廠選用國內目前秀的水力模型設計而成,高效節能穩定是LY液下泵的優點。
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長軸液下泵結構特點
1.LY型長軸液下泵接軸結構安全可靠
2. 轉子部件可以軸向調整
3.轉子部件采用多點支撐，泵運轉安全可靠。
4.滑動軸承采用外潤滑或自潤滑
5.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
6.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。
7.從電機端看，泵為順時針方向旋轉。
