Abstract
The invention belongs to the technical field of fluid machinery, and particularly relates to a method for evaluating the operation condition of a multistage centrifugal water injection pump. In order to solve the problem that in the prior art, the prediction precision of the operation condition of the multi-stage centrifugal pump is low, operation condition factor data of the multi-stage centrifugal water injection pump are obtained, wheel level factor data of the multi-stage centrifugal water injection pump are calculated, and the operation condition of the multi-stage centrifugal water injection pump is predicted according to various factor data influencing the operation condition of the water injection pump and result data. According to the method, the working condition early warning of the pump at a certain moment can be predicted through the method, the pump can be located on a certain stage of impeller, the problem can be found and solved before the impeller breaks down through maintenance and replacement in advance, the working condition of the water injection pump can be predicted, and the service life of the water injection pump can be prolonged. The maintenance cost and the failure rate are reduced, and the reliability and the stability of the multi-stage centrifugal pump are improved.
