ZA型石油化工流程泵(簡稱:ZA、ZAO化工泵)為單級單吸懸臂式離心泵,主要用于石油、化工、合成纖維、化肥、電站、冶金、食品及醫(yī)藥等工業(yè)部門輸送清潔或含有顆粒的液體、低溫或高溫的液體 中性或有腐蝕性的液體,輸送介質(zhì)的溫度一般為-45℃-180℃。
特點
泵為單級、臥式、蝸殼泵。泵體為腳支撐,單吸葉輪。軸向吸入,徑向排出;
根據(jù)使用條件采用前、后密封環(huán)及平衡孔進行水力平衡;
填料箱具有冷卻或加熱管接頭。軸封采用填料密封,也可采用單端面或雙端面機械密封。配有冷卻、沖洗或密封液系統(tǒng)。
吸入及排出管法蘭的額定壓力等級相同。
軸承用潔凈的22號機械油潤滑。
泵的旋轉(zhuǎn)方向:從原動機端看,為順時針旋轉(zhuǎn)。
