  常用耐腐蚀化工泵多为单级叶轮或单级双吸式转子。检修时首先检查叶轮外观并清洗干净, 不管是更换备件安装新叶轮, 还是清洗旧叶轮, 回装后均要做静平衡, 必要时还要做动平衡。叶轮和轴的配合采用H/ h , 安装叶轮时键和键槽要正确接触。对于转子部分的轴径允许弯曲不大于0. 013mm , 对于低速轴最大弯曲应小于0. 07 mm , 对高速轴最大弯曲应小于0. 04 mm。轴套部分与轴的装配采用H/ h。 对于转子部分的轴, 检修后轴径向跳动不大于0. 013 mm , 轴套不大于0. 02 mm , 叶轮口环不大于0. 04 mm , 叶轮端面跳动不大于0. 23 mm。两端轴径不大于0. 02 mm。但对于结构较复杂的离心泵,上述数据根据泵的状况标准而有所变化。

Chemical pump impeller and rotor maintenance Corrosion-resistant chemical pumps used mostly for single-stage or single-stage double-suction impeller rotor. Check the impeller when the first maintenance and clean appearance, whether it is installing a new impeller replacement parts, or cleaning the old impeller, back to the static balance after installation are to be done, if necessary, to do balancing. Impeller and shaft with the use of H / h, when the impeller key and keyway installed correctly exposed. Part of the rotor shaft allows for the bending is not greater than 0. 013mm, the maximum bending for low-speed shaft should be less than 0. 07 mm, the largest high-speed shaft bending should be less than 0. 04 mm. Part of the assembly with the shaft sleeve using H / h. For part of the rotor shaft, repair rear axle runout is less than 0. 013 mm, sleeve is not greater than 0. 02 mm, impeller Sandy Bay is not greater than 0. 04 mm, impeller face runout is not greater than 0.23 mm. Both ends of the shaft is not greater than 0. 02 mm. But for more complex structure of centrifugal pump, the pump according to the status of data standards vary.
