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(huán)保等多個行業(yè)部門,可用來進(jìn)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(nèi)目前更的水力模型設(shè)計(jì)而成,高效節(jié)能穩(wěn)定是LY液下泵更大的優(yōu)點(diǎn)。
LY/LYO/LYG系列長軸液下泵,選用國際的水力模型,泵設(shè)計(jì)和制造按AP1610VS4型執(zhí)行,泵軸由泵蓋和滑動軸承體內(nèi)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(shí)也適用于輸送含有顆?;蚶w維的各類污水。LY/LYO型其輸送介質(zhì)溫度范圍為-20℃~+120℃,LYG型輸送介質(zhì)可達(dá)+400℃,工作壓力可達(dá)1.6MPa。
二、LY長軸液下泵結(jié)構(gòu)特點(diǎn)
1.LY型長軸液下泵接軸結(jié)構(gòu)安全可靠
2. 轉(zhuǎn)子部件可以軸向調(diào)整
3.轉(zhuǎn)子部件采用多點(diǎn)支撐,泵運(yùn)轉(zhuǎn)安全可靠。
4.滑動軸承采用外潤滑或自潤滑
5.泵起動時(shí),葉輪已浸沒在介質(zhì)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(zhuǎn)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(jī)端看,泵為順時(shí)針方向旋轉(zhuǎn)。
