Description
Technical field:
The present invention relates to a kind of oil particles dustiness monitoring method and device that utilizes vibration performance, relate to lubricating oil and pollute the on-line monitoring technique field.
Background technology:
The good lubrication state of equipment can reduce wear out failure greatly, effectively prolongs the serviceable life that machine is not equipped with, and reduces shutdown loss to greatest extent.Simultaneously, the abundant information that has state of runtime machine in the lubricating oil owing to the existence of the wear particle of component of machine.The oil liquid monitoring technology is by analyzing the performance change of (or actuating medium) with lubricator of monitored machine and the situation of the wear particle that carries, obtain the information of the lubricated and state of wear of machine, estimate the operating mode and the prediction fault of machine, and the technology of definite failure cause, type and part.
Though in the operation cost of vehicle or equipment, cost of lube only accounts for 0.5%-1.5%, but the improper or improper use of the quality of lubricating oil is the important root that breaks down, and revitalizes 700 the mechanical faults investigation of association to 14 kinds of reasons initiations of enterprise according to Japan's machinery, the fault that takes place because of insufficient lubrication 166 times, account for 25.7%, lubricating method 92 times improperly accounts for 14.3%, relevant account for 40% altogether with lubricated, therefore doing well lubricated is a ring of the utmost importance that reduces fault.Along with the increase of industry member to the monitoring and diagnosis technical need, to the part analysis of existing lubricant dustiness detection technique both at home and abroad, existing oil contamination analyzing detecting method and technology mainly contain: method of magnetic, counting method, material characteristics method etc., they have following characteristics: detect principle, method is various, the equipment complexity, the cost height, assay method is loaded down with trivial details.
Summary of the invention:
The objective of the invention is a kind of oil particles dustiness monitoring method and device that utilizes vibration performance, vibration performance according to contamination particle in the lubricating oil and fluid, extract the quantity and the size of pollutant, be converted to the evaluation criteria of NAS1638, the pollution level of on-line monitoring fluid overcomes deficiencies such as existing device for monitoring oil contamination equipment complexity, cost height and assay method be loaded down with trivial details.
The present invention mainly contains the use element of lubricating oil to be monitored, and described element has oil-in and oil-out, side at oil-in and the close element of oil-out is provided with high-precision pressure transducer respectively, at described element outside surface center the three-dimensional acceleration transducer is set equidistantly, the detection signal of described pressure transducer and acceleration transducer is handled the signal acquisition process amplifying unit and the display device of computing and formed.
The technical solution adopted for the present invention to solve the technical problems is: utilize lubricating oil use equipment in operational process because self or extraneous exciting force effect, oil-in and oil-out at element to be monitored are provided with high-precision pressure transducer, at described element surface three three-dimensional acceleration transducers are set, lubricating oil to be detected flows to the oil-in of described element under certain pressure, the vibration performance of the fluid pressure transducer by oil-in is detected, enter element internal then, at this moment if element internal is because the metal worn particle that wearing and tearing or other reasons produce can produce vibration together along with fluid, and export its vibration performance by three three-dimensional acceleration transducers of element surface, flow out element by oil-out at last, and detect through the vibration performance that the pressure transducer of oil-out will carry the fluid of metal worn particle; These vibration characteristic signals that detect are set up database with the process experiment and are compared by terminal block entering signal harvester under certain control strategy effect, can draw corresponding oil contamination value.
The invention has the beneficial effects as follows, utilize lubricating oil to use equipment self or extraneous exciting force effect in operational process, the vibration signal that generation is relevant with the metal worn particle characteristic with fluid obtains the soiling value of lubricating oil, and is simple in structure.This invention utilization is provided with the mode of pressure transducer at oil-in and oil-out, can treat the wear condition of monitoring element monitors in real time, and by three three-dimensional acceleration transducers being installed at element surface, the influence of the vibration of lubricating system in the testing process can be reduced, improve detection accuracy; Utilize experiment to set up database, can make different types of lubricating oil in the testing process of this invention, not be subjected to the fluid Effect on Performance, test result is more reliable, can be in system work process on-line monitoring go out the class of pollution of fluid, realize functions such as demonstration, storage, printing, reduce the influence of human factor testing result.
