Abstract
The invention relates to an oil particle distinguishing counter, and especially relates to an oil particle distinguishing counter for respectively counting non-metal particles, ferruginous particles and non-ferruginous metal particles in oil. A detection zone of the counter is a narrow-middle micro channel, and the outlet of the channel is provided with a negative pressure pump for providing power for the oil flow; detection comprises upstream detection and downstream detection; the upstream detection which adopts a light blockage process is used to count all the particles; and the downstream detection which adopts an inductance process is used to detect the quantity of the ferruginous particles and the non-ferruginous metal particles, and obtained pulse signals are amplified, filtered, compared, counted and the like to realize the qualitative and quantitative analysis of the ferruginous particles, the non-ferruginous metal particles and the non-metal particles. The counter which solves a defect that present oil particle distinguishing counters cannot classifiedly count has a wide application value.
Description
Affiliated technical field
The present invention proposes a kind of oil-liquid-solid particulate pollutant counter, the fluid particle collector that especially can count respectively the non-metallic particle in the fluid, irony particle, non iron metallic particles.
Technical background
Oil analysis in the industry is the analysis that lubricating oil and other oil products that is used for plant equipment are carried out.Oil analysis detects, forecasts trouble location, and instruct the maintenance of plant equipment and maintain significant for the operation conditions of grasping plant equipment.Wherein most important analysis content then is the particulate pollutant analysis, because particulate pollutant contains the abundant information at friction, the wearing and tearing origin cause of formation and position. carry out quantitative test through the grain count device usually.At present, known fluid particle collector generally adopts the shading method, can count all particles in the fluid, but can not carry out differential count to particle, wants the character and the quantity of analysing particulates, need do iron spectrum or spectral analysis.Analyzing iron spectrum is to let fluid through a high strength, high-gradient magnetic field, utilizes magnetic force to be deposited to successively by size on the substrate by abrasive dust, analyzes abrasive nature then.But analyzing iron spectrum can not be caught representative non-metallic particle and non iron metallic particles, so diminish judgement to the overall situation.The staff needs the skilled operating instrument of long-term training ability and obtains enough experiences simultaneously, and precision is lower.Spectral analysis utilizes principle and the experimental technique of spectroscopy to confirm the structure and the chemical constitution of material.But spectral analysis can not detect the sample that contains moisture, receives ectocine big, be difficult to accomplish accurate detection for the nonmetal material that waits, and the cost of equipment is high.
Summary of the invention
In order to solve the defective that present fluid particle collector can not differential count; The present invention provides a kind of fluid granulomere minute counter; Not only can count contained solid particle in the fluid, can also be to the irony particle, non iron metallic particles and non-metallic particle carry out qualitative, quantitative test.
The present invention solves the scheme that its technical matters adopts: the fluid channel that adopts an internal diameter gradual change; Narrow part is a surveyed area, and it is the mobile power that provides of fluid that runner exit is installed a negative pressure pump, and it is that upstream and downstream detects that the two-stage of pick-up unit detects; Light blockage method is adopted at the upper reaches; Be used for detecting the sum of all particles, inductance method is adopted in downstream, is used for detecting the quantity of irony particle and non iron metallic particles.Its principle of work is: when a contamination particle (3) process first order surveyed area; The meeting stop portions is by the light intensity of light source (2) through surveyed area directive optical detection device (8); The luminous energy that optical detection device (8) is accepted reduces; Therefore also corresponding the diminishing of voltage signal that changes into forms a voltage pulse signal, and the size of its size and particle is directly proportional.When an irony particle during through second level surveyed area, because its magnetic permeability is greater than the magnetic permeability of fluid, thereby make the inductance value of coil become big, form a positive pulse relevant with grain size; When a non iron metallic particles through out-of-date because it inner forms the current vortex opposite with magnetic direction, weakened original magnetic field of telefault, thereby inductance value diminished, form a negative pulse.The inductance amplification of usefulness back and treating apparatus are with pulse signal amplification, filtering, comparison, counting; Just can learn the quantity of irony particle and non iron metallic particles; After through simple calculating, just obtained nonmetallic amounts of particles; The size of its signal value is the size of corresponding particle also, thereby reaches the purpose of distinguishing counting.
Characteristics of the present invention are: get oil sample one time, just can carry out qualitative and quantitative analysis the non-metallic particle in the fluid, irony particle, non iron metallic particles through one-time detection, and many instrumentations of instead, oil sample consumption is few, and energy consumption is low.Secondly, this counter is simple to operate, and compact conformation can be used the micro-fluid chip fabrication techniques and become mancarried device to take the scene to, also can make the on-line monitoring of fluid.

Embodiment
In Fig. 1, light source (2) is formed first order pick-up unit with optical detection device (8), light source transmission detection zone, and optical detection device changes the luminous energy that receives into electric energy, and telefault (9) amplifies with inductance and treating apparatus (6) is formed second level pick-up unit.First and second level arranges that by the upstream and downstream mode the two can be changed each other.For improving accuracy of detection, it is narrower that the runner of surveyed area is wanted, to concentrate sample.
For detecting the Signal Processing process flow diagram, as shown in the figure in Fig. 2, detected signal (1) at first passes through amplification filtering device (2); Pass through comparer (3) then, with the voltage signal of standard relatively to confirm grain size, pass through counter (4) pulse count then; The data that collect are delivered to microprocessor (5) and are handled, and show through display (6) then, go out through printer defeated (7); Can also connect other external unit (8), like computing machine etc.Can also increase or reduce the number of comparer as required.
