Abstract
The invention discloses a kind of method for improving the online fluid metal worn particle electromagnetic monitoring degree of accuracy, using the copper foil pipe for tube wall is inserted in electromagnetic monitoring sensor being machined with multiple micro through holes, effectively stop interference signal caused by non-conductive medium change.
Description
Technical field
The present invention relates to a kind of lossless detection method, and online fluid metal worn particle electromagnetic monitoring is improved more particularly to one kind
The method of the degree of accuracy.
Background technology
Electromechanical detection method is one of engine oil on-line monitoring method, and generally use senses through mode electromagnetic monitoring
Device is enclosed on outside the tube wall of engine oil return pipe, reaches engine health shape by monitoring the quantity of the metal worn particle in oil return pipe
The monitoring purpose of state.Because metal worn particle small volume, flow velocity are fast, electromagnetic monitoring sensor needs the work under the conditions of limiting snesibility
Make, it is to non-conductive medium（Such as bubble）Also quite sensitive, cause to report by mistake, influence the correctness of testing result.
The content of the invention
It is an object of the invention to overcome the deficiency of prior art, there is provided one kind improves online fluid metal worn particle electromagnetism prison
The method for surveying the degree of accuracy, the copper foil pipes of multiple micro through holes is machined with using tube wall is inserted in electromagnetic monitoring sensor, is stopped non-
Interference signal caused by conducting medium changes.
The technical solution adopted for the present invention to solve the technical problems is：One kind improves online fluid metal worn particle electromagnetism prison
The method for surveying the degree of accuracy, it is characterised in that：Copper foil pipe, the pipe of the copper foil pipe are inserted in oil pipe in electromagnetic monitoring sensor
Outer wall is close to oil pipe inner tubal wall, and the tube wall of the copper foil pipe is machined with multiple micro through holes；Material, the thickness ginseng of the copper foil pipe
Number, determines according to rating test, should meet to require as follows：Electromagnetic detection pumping signal can be penetrated；It is electrically conductive to be shielded with playing
Effect, stop interference signal caused by non-conductive medium change.
The invention has the advantages that a kind of method for improving the online fluid metal worn particle electromagnetic monitoring degree of accuracy, is used
The copper foil pipe that tube wall is machined with multiple micro through holes is inserted in electromagnetic monitoring sensor, effectively stops that non-conductive medium change causes
Interference signal.
The present invention is described in further detail with reference to embodiments, but one kind of the present invention improves online fluid metal
The method of abrasive particle electromagnetism monitoring precision is not limited to embodiment.
Brief description of the drawings
The present invention is further described for middle embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the screen method schematic diagram that insertion tube wall is machined with multiple micro through holes in the oil pipe of the embodiment of the present invention.
In figure, 1. electromagnetic monitoring sensors, 2. oil pipes, 3. copper foil pipes, 30. micro through holes, 4. non-conductive mediums.
Embodiment
Embodiment, a kind of method for improving the online fluid metal worn particle electromagnetic monitoring degree of accuracy, in electromagnetic monitoring sensor 1
Insertion copper foil pipe 3 in interior oil pipe 2, the pipe outer wall of the copper foil pipe 3 is close to the inner tubal wall of oil pipe 2, and the tube wall of the copper foil pipe 3 adds
Work has multiple micro through holes 30；The material of the copper foil pipe 3, thickness parameter, are determined according to rating test, should meet to require as follows：
Electromagnetic detection pumping signal can be penetrated；It is electrically conductive to play shielding action, stop that non-conductive medium 4 disturbs letter caused by changing
Number.
Above-described embodiment is only used for further illustrating that one kind of the present invention improves online fluid metal worn particle electromagnetic monitoring standard
The method of exactness, but the invention is not limited in embodiment, every technical spirit according to the present invention are made to above example
Any simple modification, equivalent change and modification, each fall within the protection domain of technical solution of the present invention.
