Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
Embodiment one
The invention discloses a kind of penetrant detecting method and equipment, include the following steps,
One, it is surface-treated, removes object surface pollutant to be checked；
Clean any possible pollutant for influencing Liquid penetrant testing is removed, the cleaning of object surface to be checked is kept, meanwhile, it cannot damage
The work functions of examined workpiece.It cleans region and extends to the outside 25mm or more from detection position surrounding.
The removing of pollutant can select: mechanical chipping, and chemical cleaning or solvent cleaning are one such or a variety of, select
When should carry out the case where comprehensively considering object to be checked.Coating must be removed with the method for chemistry and cannot use the side of polishing
Method.
Two, apply penetrating fluid to object surface to be checked；
Common applying method has spraying, brushing, flow coat and dip-coating.
Three, the object to be checked of oil surface penetrating fluid is put in pressure pan, places certain time；
Time under normal pressure, applying bleeding agent is no less than 10min；For stress corrosion cracking (SCC) because it is especially subtle, extend
The object to be checked of time of penetration.And when carrying out applied voltage test in pressure pan, since pressure pan chamber pressure is higher, molecular motion speed
Degree is accelerated, therefore penetrating fluid fully penetrates into the time in crackle compared with being shortened under normal pressure, thus shorten that penetrating fluid places when
Between, accelerate detection efficiency, while pressure is bigger, more can ensure that sharp bleeding agent fully penetrates into crackle full of crackle.
Temperature general control is permeated within the scope of 10~50 DEG C, and temperature is too high, and bleeding agent is easy to do on examined workpiece, no
Just it cleans；Temperature is too low, bleeding agent retrogradation, and dynamic permeates parameter and is affected.
Simultaneously when the temperature of examined workpiece is not in recommended range, performance comparison test can be carried out, to verify detection knot
The reliability of fruit.Tested surface should be allowed to be in wetting state in entire time of penetration.
Four, object to be checked is cleaned into the penetrating fluid on object surface to be checked after pressure pan taking-up；
Emulsification times, which must be controlled, when the removal of emulsifying bleeding agent afterwards prevents Over emulsfication, is obtaining the premise of suitable background
Under, the shorter the time of emulsification the better.
It must not back and forth be wiped when the removal of solvent-removal penetrant, not handy cleaning agent directly rinses tested surface.
The water temperature of the removal of water-washing type bleeding agent is 10~40 DEG C, and hydraulic pressure is no more than 0.34MPa, is obtaining suitable background
Under the premise of, the shorter the time of washing the better.
In the removal of bleeding agent, the situation of over cleaning or cleaning deficiency is prevented, overclean may cause defect and show
It does not come out or missing inspection, cleaning deficiency can make background overrich again, be unfavorable for observing.
Five, apply imaging agent to object surface to be checked；
The applying mode of imaging agent has spraying, brushing, flow coat and dip-coating etc., and it is 300~400mm that distance, which is detected surface, when spraying,
The angle for spraying direction and plane was seized is 30~40 °, and one position does not allow back and forth to brush several times when brushing.
Six, the penetrating fluid inside defect is rasterized agent and adsorbs, and is observed；
Observation display should carry out in 7~60min after imaging agent application.According to the case where article to be measured determine display observation when
Between.
The light source of observation should be met the requirements, and general white light illumination should be greater than 1000Lx, when being unable to satisfy, must not be lower than
500Lx, when fluorescence detection, the white light illumination in darkroom should not exceed 20Lx, at black light lamp 380mm.
When carrying out fluorescence detection, testing staff, which enters darkroom, should dark adaptation time.
