Technical field
The present invention relates to a kind of oil liquid monitoring technology, relate in particular to a kind of system and on-line monitoring method thereof that can on-line monitoring fluid metal worn particle.
Background technology
The abrasive dust that carries in fluid has reflected the state of wear of plant equipment.Lubricating oil is sampled, comprehensive utilization Debris Analysis technology and oil analysis technology, analyze concentration, size, the pattern that extracts abrasive particle in fluid and become grading information, can understand all sidedly the state of wear of equipment and the pollution situation of lubricating system, estimate the operation conditions of machine and to its possible fault pre-alarming, for machine state monitoring and predicting residual useful life provide important foundation.
Traditional oil liquid monitoring technology is mainly to adopt the method for off-line monitoring, need expensive exact instrument (as Atomic Emission Spectrometer AES, near infrared spectrometer and ferrograph analyzer etc.), and detection time is long.Show according to investigation, the result that off-line monitoring is analyzed is due to shortcomings such as sample representation are poor, for the equipment of serious wear, has 50% not pinpoint the problems, and 45% shows to lose efficacy and is about to occur, and only 5% detects serious problems.Consumed so a large amount of manpower and materials, and tracing trouble in time.And the pollution of fluid is the process of a quantitative change to qualitative change, and the time that this process occurs is unknown,, so must constantly to fluid, carry out on-line monitoring, just can not make the monitoring of fluid be full of contingency.Thereby, performance and the state of lubricating oil carried out on-line monitoring oil contamination, fluid is carried out effectively polluting and controlling, increase its serviceable life, guarantee its safety, work efficiently, the development of the national economy and Defence business development are all had great significance.
Online oil liquid monitoring technology is to answer the heavy mechanical equipment of robotization, multifunction to need and living a kind of new analytical technology; in the situation that equipment is not shut down, monitoring oil contamination state does not disintegrate; the fault of diagnostic device and reason thereof; thereby carry out targetedly maintenance and repair, increase the promptness of machinery maintenance and the means effectively of convenience.The especially online wear particle monitoring technology of online oil liquid monitoring technology starts to become one of current study hotspot and trend.Utilize online wear particle monitoring technology, installation of sensors in equipment lubrication oil circulating oil path, can be lubricated oil sampling and Debris Analysis in real-time continuous ground automatically in the plant equipment normal course of operation, obtain in time equipment running status.This, to improving equipment attrition monitoring and failure prediction level, realizes the equipment condition based maintenance, effectively reduces equipment maintenance cost, increases economic efficiency and has great significance.
Up to now, online oil liquid abrasive grain monitoring method mainly contains: method of magnetic, counting method, material characteristics method etc., but each tool shortcoming.Such as method of magnetic can only detect for having ferromagnetic abrasive particle; can't measure non-ferromagnetic abrasive particle and outside contamination composition granule; and the counting rule can't obtain the information of abrasive particle material at all; ultrasound wave abrasive particle on-line monitoring is a kind of method of utilizing material property to realize wear monitoring that has patent report abroad; this method is utilized the sensor emission ultrasound wave; can the principle of different wave feedback be arranged to ultrasound wave according to the abrasive particle of unlike material, shape and size, realize the on-line monitoring of abrasive particle.Present this method is not yet seen the report of practical application, and the abrasive particle of unlike material, shape and size need really obtain in actual monitoring and realize to the theoretical analysis that ultrasound wave has different feedbacks.At present, develop and a kind ofly can extract that wear particle size distributes, morphological feature, can extract again the abrasive particle composition characteristics online oil liquid monitoring technology be that industry member is looked forward to.
Summary of the invention
Goal of the invention:, in order to overcome the deficiencies in the prior art, the invention provides a kind of fluid metal worn particle on-line monitoring system and monitoring method thereof, can analyze the online oil liquid monitoring technology of wear particle size distribution, morphological feature and material.
