特點Features IH系列化工泵系單級單吸化工泵，是取代F型耐腐蝕離心泵的節能型更新換代產品．該產品執行標準：GB5662-85、ISO2858、GB/T5656-94； Series IH chemical pump is radial split and back pull out structure, so there is no need of dismantling the pipeline when check and repair. 泵體軸向吸入，徑向排出，腳支承式。泵與原動機連結用加長聯軸器； Pump casing is axial suction, radial discharge and supported by foot .Pump is connected with the driver by spacer coupling. 泵軸承用潔凈的22號機械油潤滑，泵運轉前須向懸架內加潤滑油油標中心線以上2 mm左右; Bearing are lubricated by clean 22 mechanical oil, bearing housing must be filled with lubricant to about 2mm over the central line of oil level gauge before pump operation. 大直徑葉輪用填料密封、機械密封、付葉輪密封（動力密封）。 Shaft seal adopts packing seal, mechanical seal, vice-impeller seal (dynamic seal) 用途Applications 主要用于石油、化工、合成纖維、化肥、電站、冶金、食品及醫藥等工業部門輸送不含懸浮顆粒的腐蝕性或不允許污染的介質。 It is mainly used in oil, chemical industry, synthetic fiber, fertilizer, power plant, metallurgy, food and pharmaceutics, etc .industrial departments to transport corrosive medium without suspended grain or medium which must not be polluted. 工作條件Operating Conditions 介質溫度(Medium temp)：-20℃＜T＜+105℃; 特殊措施可達180℃：It can reach 180℃ if special measures are taken; 流量（Capacity）：Q=3.4～460(m3/h); 揚程(Head):H=3.7～128(m); 轉速(Speed):n=1450～2950r/min; 泵的旋轉方向：由電動機方向往泵看為順時針方向旋轉. Rotation direction: clockwise rotation viewed from motor end. 性能表中軸功率的介質比重為1g/cm3，粘度為1mm2/s計算而得。 In performance chart, power of shaft is calculated by specific gravity of medium as 1g/cm3,and viscosity as 1mm2/s. 電機配用原則：若比重≤1.0，按1.0配用電機;若1﹤比重≤1.35,按1.35配電機;若1.35﹤比重≤1.85,按1.85配電機. Motor matching principle: if specific gravity ≤1.0，match motor according to 1.0;if 1﹤specific gravity ≤1.35,match motor according to 1.35;if 1.35﹤specific gravity ≤1.85,match motor according to 1.85
