一 、產(chǎn)品簡介：
化工流程中強制循環(huán)、海水養(yǎng)殖
、城市煤氣工程
、水處理系統(tǒng)
。此系列泵能夠經(jīng)濟有效地輸送大流量
、低揚程的、均勻的或含有一定顆粒的
，化學(xué)中性的或有腐蝕性的液體（強腐蝕性液體需說明）。 泵效率高
、能砂耗小
；泵在整個性能范圍內(nèi)的能耗均勻
，可以在閉閥下啟動，而電機不至過載
；過流截面大
、不易堵塞；結(jié)構(gòu)緊固
、壽命長。
結(jié)構(gòu)
THW型化工混流泵為臥式可拉出式結(jié)構(gòu)
。在檢查或拆卸葉輪
、軸封時，毋須將與泵體相連接的管路拆開
。泵軸裝有防護軸套，軸承用稀油潤滑
，軸承箱里的泊位
，可由“恒位”油杯來控制
。泵體上鑄有支腳
，可承受來自管路的任何載荷，并直接傳給基礎(chǔ)
。因此，轉(zhuǎn)子不會因泵承受載荷而產(chǎn)生彎曲
，從而保證了軸承具有最佳的使用壽命
。泵上還配備完整的排氣裝置
，以供吸入管路排氣。
軸承 采用球軸承
。
軸封 采用填料密封或雙端面機械密封
。
傳動 從驅(qū)動端看泵，為順時針方向旋轉(zhuǎn)
。
