產(chǎn)品概述：
R型熱水循環(huán)泵系單級(jí)單吸和兩級(jí)單吸懸臂式離心泵，適用于冶金、電站，化工等部門，用于輸送250℃以下不含固體顆粒的高壓熱水之用。被輸送熱水溫度為250℃，泵進(jìn)口壓力為0.5MPa；當(dāng)熱水溫度不高于250℃，泵進(jìn)口壓力不應(yīng)大于0.3MPa。
型號(hào)說明
100R－37A
100－表示進(jìn)口直徑為100mm
R－表示熱水循環(huán)泵
37－表示泵設(shè)計(jì)揚(yáng)程為37m
A－表示葉輪外徑改變
結(jié)構(gòu)型式
泵為單級(jí)單吸和兩級(jí)單吸懸臂式，用浮動(dòng)環(huán)密封，軸承為滾動(dòng)軸承和球軸承，采用稀油潤(rùn)滑。
旋轉(zhuǎn)方向
從電機(jī)端看，泵為逆時(shí)針方向旋轉(zhuǎn)。
主要零件材質(zhì)
按不同的壓力，主要零部件的材質(zhì)有：Ⅰ類：QT500-7；Ⅱ類：ZG230-450；Ⅲ類：ZG3Cr13。
成套范圍
成套供應(yīng)泵、電機(jī)、聯(lián)軸器、底座。
