一.概述
ZA型化工流程离心泵,按照API610和VDMA24297(轻/中型)规范而设计、生产的产品。可输送各种温度和浓度的硫酸、硝酸、盐酸和磷酸等无机酸和有机酸溶液;各种温度和浓度的氢氧化钠和碳酸钠等碱性溶液;各种盐溶液;各种液态石油化工产品、有机化合物以及其它有腐蚀性的液体。该型泵适用于炼油厂、石油化学工业煤加工工程、低温工程、造纸业、制糖业、供水厂、海水淡化厂、发电厂、环保工程和船舶业等。从电动机端看,泵的旋转方向为顺时针方向旋转。
二.结构特点
该类型的化工流程泵是采用的标准管路按API规范设计。叶轮可用闭式、半开式、开式三种。可输送清洁,含颗粒,含少量气体介质。也可输送高温、低温、强腐蚀介质。叶轮设有平衡孔加耐腐环,平衡轴向力。泵体和轴承架用中间连接段连接。根据不同的工况条件,中间连接段可采用不同的材质,避免输送强腐蚀介质时轴承架、轴承严重腐蚀。同时中间连接段设有水冷腔,通冷却循环水,阻隔高温介质将高温传到轴承上。密封形式可采用填料密封,单、双端面机械密封,集装式单端面机械密封。根据不同情况和用户对冷却与冲洗要求,密封可按API682设计规范从案中选用。轴承架设计有空冷散热片、风冷风扇、水冷腔三种形式,用户可根据使用工况选用。轴承由油环从油箱里溅稀油润滑。油箱内的油由水冷腔的水冷却,轴承内的热由冷水带走,以保证轴承随时处于正常工作状态。根据介质温度和压力等情况,支撑形式采用中心支撑和脚架支撑。吸入及排出法兰的额定压力等级相同。
