Accompanying drawing explanation
Fig. 1 is specific embodiment of the invention schematic flow sheet.
Detailed description of the invention
Below in conjunction with Figure of description and concrete preferred embodiment, the invention will be further described, but the most therefore and
Limit the scope of the invention.
As it is shown in figure 1, the wind-driven generator wheel-box method for diagnosing faults of the present embodiment, comprise the steps: S1. pair
The lubricating oil of wind-driven generator wheel-box carry out oil product detection analyze, analyze wind-driven generator wheel-box whether break down or
There is the risk broken down；S2. wind-driven generator wheel-box is carried out vibration detection, analyzes wind-driven generator wheel-box and send out
The position of raw fault and fault level；S3. wind-driven generator is carried out endoscope check, determine wind-driven generator wheel-box
Fault type and fault degree.
In the present embodiment, the detection of the oil product in step S1 analysis includes: lubricating oil is carried out physical and chemical index analysis and light
Analysis of spectrum；Physical and chemical index analysis includes kinematic viscosity analysis, total acid number analysis, moisture content analysis and particle counting analysis；
When physical and chemical index analysis result is the most up to standard, it is judged that wind-driven generator wheel-box exists the risk broken down, need lubrication
Oil carries out purified treatment or more oil change；Spectrum analysis is for analyzing the content of special metal element in lubricating oil, specific gold
Belong to element and include the metallic element in additive and the metallic element contained by wind-driven generator wheel-box, when the metal in additive
When element is less than desired value, it is judged that wind-driven generator wheel-box exists the risk that breaks down, need suitably to increase additive or
More oil change；When the metallic element contained by wind-driven generator wheel-box detects and exceeds standard, it is judged that wind-driven generator wheel-box is sent out
Raw abrasion, it may occur however that fault.
In the present embodiment, the abrasion of lubrication oil viscosity change and machinery is directly related, when viscosity change is more than 10%
Time, then should change more oil change.Deterioration of lubricant mainly oxidation, oxidation can generate acidic materials, and acid number raises.Lubricating oil
After coming into operation, total acid number is tracked detection and can reach two purposes: understand the performance of lubricating oil, determine that lubricating oil is
No this changes；After lubricating oil comes into operation, if substantially increased when acid number is compared with fresh oil, illustrate that lubricating oil there is a problem.As
Fruit is not suspected for the performance of lubricating oil, then should improve the use condition of lubricating oil, it can be common that lubricating oil is by dirt
Dye, oil temperature are not controlled well.Lubricating oil itself has hygroscopicity, can absorb the moisture in air, therefore it is noted that seal, for
Environment moist, easily contact water, and the place that air humidity is big, monitoring moisture is extremely important.Lubricating oil has necessarily
Oil-water separation ability, the lubricating oil that oil and water separation capability is good can be divided into rapidly oil, water layer, and the water separated just can be drained,
But lubricating oil itself also can absorb moisture, and the moisture that can bear is the most limited, a small amount of moisture just can allow profit
Lubricating oil performance is given a discount, and therefore monitoring moisture is critically important.To carry out simultaneously waterproof, except water conservancy project make, especially to rely mainly on prevention.
If the moisture index exceeding standard of lubricating oil, also should the most more oil change.The cleannes of equipment lubrication internal system are the most non-
The normally off key, particle counting can reflect the cleannes of system, also can reflect strainability simultaneously, but also be important changing oil
Index, if particle counting is too high, needs to replace lubricating oil.In use, lubricating oil carries the impurity of internal system,
Along with the accumulation of impurity, the performance of lubricating oil can be affected.Effective filtration system not only can extend the service life of oil, also
The abrasion of equipment can be reduced.Detection special metal constituent content mainly has two effects, a mill being to detect device interior
Damage, when in lubricating oil detection have constitute gear-box special metal element time, then explanation gear-box generation premature wear, can under
The vibration detection of one step plays checking effect, it is ensured that the accuracy of checkout and diagnosis；Another is the metal unit in detection additive
Element situation, additive exhausts, and is one of the reason of deterioration of lubricant.
In the present embodiment, step S2 includes carrying out wind-driven generator wheel-box vibration detection, analyzes trouble location, and
According to VDI3834 standard determination fault level.The concrete steps of step S3 include: according to trouble location determined by step S2,
By endoscope, trouble point is carried out detection to confirm, determine type and the fault degree of fault.By endoscope check, Ke Yizhi
That sees finds out fault degree, and diagnostic result is played decisive role；Additionally can be seen that fault type, such as galvano-cautery, point
Erosion, broken teeth, abrasion etc., according to different fault types, analyze and find out different failure causes, provide different diagnostic recommendations,
Problem is solved from root.
Above-mentioned simply presently preferred embodiments of the present invention, not makees any pro forma restriction to the present invention.Although the present invention
Disclosed above with preferred embodiment, but it is not limited to the present invention.Therefore, every without departing from technical solution of the present invention
Content, according to the technology of the present invention essence to any simple modification made for any of the above embodiments, equivalent variations and modification, all should fall
In the range of technical solution of the present invention protection.
