Standard difference analysis between domestic and overseas centrifugal pump operation management

In order to decrease failure rate of centrifugal pump and maintenance costs, the operation management standards of centrifugal pump at home and abroad have been sorted thoroughly. The differences of technical standards for centrifugal pump at home and abroad is deeply studied from three aspects, namely design and installation, operation management, and maintenance and repair. The advancements of Russian, American and ISO standards are presented including the requirements of the connection between the pump and inward and outward pipelines, the logical control relationships of pump chambers' ventilation system, monitoring pump foundation subsidence, the situation of pump's emergent shutdown, the period of pump inspection and maintenance, as well as the pump bearing box, pump shaft vibration amplitude and speed limitations. It is suggested to strengthen the formulation and revision of standards by consulting the advanced concept of overseas related standards to improve the domestic centrifugal pump operation management standards.
