【 摘 要 】

The motor free end vibrates at rated speed after overhaul of condensate pump; Through collecting field data and checking maintenance records, the fault diagnosis and troubleshooting of A condensate pump motor with excessive vibration was carried out based on the mechanism of vibration, and the cause of the fault was accurately analysed. By taking effective measures such as replacing the expansion joint at the inlet pipe, adjusting the concentricity of the pipes before and after the expansion joint, and adding A safety valve on the inlet pipe, the problem of excessive vibration of the condensate pump motor A has been thoroughly solved, and the hidden danger of equipment has been eliminated successfully.
