Embodiment Construction
[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0051] The flow chart of the mixed-flow pump online comprehensive monitoring method provided by the present invention is as follows figure 1 shown, including the following steps:
[0052] (1) Data collection
[0053] Collect the real-time operating status data and historical operating status data of several large mixed-flow pump units for a period of time, and obtain the real-time operating status data groups and historical operating status data groups corresponding to each large mixed-flow pump unit at several points in time, which will be real-time The running state data set and the historical running state data set are stored and uploaded to the server through the network.
[0054] Among them, the operating state data includes the tra...

The invention relates to an on-line comprehensive monitoring method and device for a mixed-flow pump. The on-line comprehensive monitoring method comprises the steps that real-time running state dataof a mixed-flow pump unit and historical running state data are collected, and the different types of evaluation indexes are established; a state recognition model reflecting breakdown states corresponding to the different types of evaluation indexes is constructed according to the historical running state data; the real-time running state data representing all evaluation indexes in a real-time running state data group are input into the corresponding state recognition model, and the corresponding difference coefficient or residual error is calculated; whether the difference coefficient or theresidual error is higher than a set safety prewarning line or not is judged, if the difference coefficient or the residual error is higher than the safety prewarning line, then the corresponding evaluation index of the mixed-flow pump unit is judged to be in the breakdown state, state pre-warning is conducted. According to the on-line comprehensive monitoring method, the state recognition model is constructed according to the historical running state data of the mixed-flow pump, and the real-time running state data of the mixed-flow pump are input into the state recognition model to judge thesafety state of the mixed-flow pump and predict the potential breakdown of mixed-flow pump equipment.
Description
technical field [0001] The invention relates to an online comprehensive monitoring method and device for a mixed-flow pump, belonging to the technical field of equipment state detection and evaluation. Background technique [0002] Large-scale mixed-flow pumps are widely used in various industrial devices and have become the most basic production equipment. As one of the important components of many complete sets of equipment or units, large mixed-flow pumps usually work in strong vibration, high pressure, and high-speed physical environments, and have a high failure rate. Therefore, it is necessary to carry out research on its fault detection and fault diagnosis technology. [0003] At present, domestic evaluation methods for the health status of large-scale mixed-flow pump equipment are still mainly based on the analysis of the mechanism of equipment failure itself, most of which are post-event analysis. At the same time, none of these evaluation methods can quantitativel...
