Problems solved by technology
[0003] At present, the maintenance methods of hydraulic pumps in China are mainly selected based on human experience. Obviously, there are subjective factors in the above judgment methods. Therefore, there are errors in the selection of maintenance methods for hydraulic pumps, which will reduce the reliability and safety of hydraulic pump operation.
[0004] In addition, at present, the operation data of hydraulic pumps in enterprises is still in the collection and monitoring stage, and the analysis and utilization of data are relatively low.
Due to the complex composition of the hydraulic pump data of the hydroforming equipment, there are missing values and abnormal values in the data, and the data dimensions are not uniform, so the existing maintenance methods relying on human experience to select the hydraulic pump not only cannot overcome the above shortcomings, but will further increase There are errors in the selection of maintenance methods for large hydraulic pumps

The invention discloses a maintenance strategy optimization method and system of a hydraulic pump. The method includes the following steps that: a plurality of parameters related to hydraulic pump performance are acquired; hydraulic pump performance data corresponding to the parameters are selected from a database, a hydraulic pump performance data set corresponding to the parameters is determined; the hydraulic pump performance data set corresponding to the parameters is subjected to data processing, so that a third processing data set corresponding to the parameters is obtained; standardization processing is performed on the third processing data set corresponding to the parameters, so that a fourth processing data set corresponding to the parameters is obtained; on the basis of a lineardiscriminant analysis method, a hydraulic pump performance state feature set is determined according to the fourth processing data set according to the parameters; a hydraulic pump maintenance decision model is established according to the hydraulic pump performance state feature set; and on the basis of a hierarchical analysis method, the optimal maintenance strategy of the hydraulic pump is determined according to the hydraulic pump maintenance decision model, and the accuracy of the maintenance strategy is improved.
Description
technical field [0001] The invention relates to the technical field of detection, in particular to a method and system for optimizing a maintenance strategy of a hydraulic pump. Background technique [0002] The hydraulic pump is the heart of the hydraulic system. It is an energy conversion device that converts the mechanical energy input by the motor or other prime movers into hydraulic energy. Its function is to provide pressure oil to the hydraulic system. [0003] At present, the maintenance methods of hydraulic pumps in China are mainly selected based on human experience. Obviously, there are subjective factors in the above judgment methods. Therefore, there are errors in the selection of maintenance methods for hydraulic pumps, which will reduce the reliability and safety of hydraulic pump operation. [0004] In addition, at present, the operation data of hydraulic pumps is still in the stage of collection and monitoring, and the analysis and utilization of data are re...
