Adaptive state early warning system and method of working conditions of oil transmission pump

Abstract

The invention provides an adaptive state early warning system and method of working conditions of an oil transmission pump. The method comprises steps of carrying out online acquisition on characteristic parameters of operation working stations and deterioration states of the oil transmission pump, wherein the characteristic parameters comprise working condition characteristic parameters and deterioration state representation parameters; carrying out related analysis on the deterioration state representation parameters to acquire related coefficients between the deterioration state representation parameters; according to the related coefficients and the working condition characteristic parameters, dividing the working conditions of the oil transmission pump into multiple working condition sub-spaces, determining deterioration state representation signals of the working condition sub-spaces from history operation data of the oil transmission pump, and carrying out characteristic extraction and fusion on the deterioration state representation signals to acquire a deterioration evaluation index in each working condition sub-space; and according to the deterioration evaluation index in each working condition sub-space, predicating a deterioration state value in each working condition sub-space of the oil transmission pump in real time, comparing the deterioration state values with a corresponding alarming threshold and if the deterioration state values exceed the alarming threshold, outputting corresponding alarming information. According to the invention, deterioration states of the oil transmission pump can be precisely predicated under variable operation working conditions.

Description

technical field [0001] The present application relates to the technical field of intelligent diagnosis of key equipment for pipeline oil transportation, and in particular to an adaptive state early warning system and method for working conditions of oil transportation pumps. Background technique [0002] With the development of the national economy, pipeline transportation has occupied an increasingly important position in modern industry. As the key equipment for pipeline oil transportation, the oil pump is an important factor to ensure the normal operation of pipeline transportation. However, the delivery medium of the oil pump is variable and the operating conditions are complex, which not only aggravates its state degradation, but also increases the uncertainty of state prediction. Once the oil pump components fail, it may cause the paralysis of the entire pipeline transportation system, bring huge economic losses to the enterprise, and even cause catastrophic environme...
