Description
The application is the divisional application of No. 201010582424.5 applications for a patent for invention of Application No..
Technical field
The present invention relates to a kind of fluid metallic particles monitors sensor, exist more particularly, to a kind of flowing oil metal particle
Line monitors sensor.
Background technology
The good lubrication state of machinery equipment can substantially reduce abrasion, effectively extension device service life, reduce and shut down
Loss.But due to the impact of the uncertainty in actual moving process and many factors, then perfect Machine Design is typically
The equipment of being difficult to ensure that is constantly in good lubrication and state of wear, therefore to the shape that lubricates and wear and tear in plant equipment running
It is very necessary that state is monitored.Especially for aero-engine, its working condition very severe, operating load, rotating speed
It is very harsh with the condition such as oil temperature, it seem likely that wearing and tearing in the case of unconscious, in some instances it may even be possible to cause electromotor
Damage.And the purpose of oil liquid monitoring is exactly the lubricating oil being currently in use to machinery equipment using analysis of oil technology carries out total score
Analysis, it is possible to obtain the information of equipment lubrication and wear condition, and the development of equipment attrition process is predicted accordingly, failure is found in time
Or trouble-saving generation.Especially for the on-line monitoring of big abrasive particle in engine lubrication liquid, once detect big abrasive particle, i.e.,
There are great potential faults in expression, people can be reminded to take measures ahead of time, prevent the generation of electromotor burst accident.In state
Outward, Canadian GasTops companies develop MetalSCAN oil liquid abrasive grains on-line monitoring sensor, and product is initially for F-22
F-119 aero-engines used by opportunity of combat and design, F-35, european union fighter plane are also applied at present（EJ200）、AH-64
Apache's helicopter, S61 Sea-King, Pilates PC-12 series aircrafts, capital ship and wind-power electricity generation etc. are various military
Or in the product for civilian use, obtain good monitoring effect.MetalSCAN oil liquid abrasive grains on-line monitoring sensor allows oil including one
The siphunculus that liquid passes through, axially disposed outside siphunculus to have three coils concentric with siphunculus, two coil winding-directions at two ends are contrary
And mutually concatenate, by exchange electric drive, make both magnetic field contrary and cancel out each other, when the fluid with metallic particles flow through it is logical
Guan Shi, is arranged on the induced signal that the 3rd sensor coil measurement metallic particles in centre position is produced to disturbance of magnetic field, will
The induced signal of output hands over signal processing unit processes, arranged by program make the amplitude of output voltage signal and ferromagnetic particle or
Non-ferromagnetic granular size is proportional, and proportional to non-ferromagnetic granule surface area, phase place and the ferromagnetic particle of non-ferric magnetic signal
Opposite in phase.Thus, it is possible to determine the species of metallic particles, size, quality and quantity.
Domestic main Oil Monitoring Technique research concentrates on spectral analysis technique, Spectral Analysis Technology, grain count meter
In the methods such as number, means are single, and detection mode belongs to off-line type detection.Off-line type detection firstly the need of equipment downtime, so
Afterwards sample is made to fluid sampling, finally by the granule content in spectrum or Spectral Analysis Technology analysis fluid.Offline inspection
Although mode can obtain higher accuracy of detection, process is loaded down with trivial details, and analytical cycle is long, to flowing of the detection in work
Fluid metallic particles is helpless.At home aero-engine monitoring field, mainly uses lubricating oil Atomic Emission Spectral Analysis
Technology or magnetic barrier detection technique monitoring aero-engine incipient fault, although achieve certain effect, but atomic emission spectrum
Analytical technology does not still break away from offline analysis mode with magnetic barrier detection technique so as to detect that real-time is subject to certain limit
System.It is in recent years, domestic also once to attempt introducing MetalSCAN oil liquid abrasive grains sensor for rolling bearing and gear condition monitoring,
But a variety of restrictions are subject to because MetalSCAN is mainly used in military use in western countries, so far China fails to obtain military products
The Related product or technology of level.
