化工离心泵一般适用于化工厂以及化工行业，常用的化工离心泵材质有不锈钢、氟塑料材质或者碳钢等。每一种材质的化工离心泵的用途都不一样，要根据实际输送介质来决定。由于化工离心泵输送的介质往往有毒、有害、有腐蚀性，具有高温或低温，因此要求化工离心泵能满足化工工艺需求，无泄漏或少泄漏， 耐腐蚀、耐磨损，耐高温或低温，能输送临界状态的液体，运行可靠。

常见故障原因分析及处理
造成离心泵故障的原因多种多样，常见的有选型不合理及设备固有故障、安装、启动和运行故障。例如，因选型不合理造成泵超功率；因设计制造缺陷造成泵气蚀严重和流量不足；因安装故障造成泵的振动与噪声严重超标；因泵的启动和运行故障造成泵不能正常启动及出水量逐渐减少、填料发热、轴承过热等。
泵运转声音异常或振动过大 泵正常运转时，泵和电机组成的小机组应是平稳的，声音应当是正常的。如果这个小机组有杂音或异常振动，则往往是泵故障的先兆，应立即停机检查，排除隐患。

轴承过热：如果在泵的运行中发现轴承烫手，则可在下面几项中排查其原因：泵与电动不同心、联轴器对中不良或轴向间隙太小，方法是检查对中情况和调整轴向间隙、润滑油量不足或润滑油循环不良、润滑油质量差、有杂质使轴承锈蚀、磨损，转动不灵活、轴承已严重磨损、轴瓦刮研的不好，则应取出轴瓦重新刮研或更换新轴瓦、轴承间隙过小，则应重新调整轴承间隙或刮研轴瓦、轴承装配不良，则应按要求检查轴承装配情况，消除不合要求的因素、冷却水断路，则应立即检查修理冷却水装置、泵轴弯曲，则应矫正泵轴等因素。
