Description
Technical field
The invention belongs to Non-Destructive Testing and nondestructive testing technique.Be particularly suitable for detecting the size of high resistance lining layer crackle and distributing.
Background technology
High resistance lining layer is widely used because it possesses good structure.In order to guarantee its usability, it is carried out nondestructive examination is necessary.Nondestructive examination way commonly used now has: ultrasonic testing, industry CT method, acoustic emission.
Ultrasonic testing since its to have penetration capacity strong, Propagation of Energy is big, characteristics such as good directionality are propagated the advantages such as attenuation change that can produce boundary reflection or the velocity of sound and energy when running into defective in medium, be often used as the nondestructive examination of compound substance.But for high resistance lining layer, to produce effective echo desired in conjunction with situation because itself and the situation that combines of original layers do not reach UT (Ultrasonic Testing), and lining has certain roughness, make the probe bonding state surperficial be affected with it, these all are unfavorable for the Accurate Analysis to echo, thereby can not detect the crackle size and (the 1:Hiroshi Kato Ultrasonic Evaluation of theBonding Strength of Dissimilar Metal Bonds NDT﹠amp that distributes of high resistance lining layer; E International 6,1996,355-3612: Li Run people Wu Xiao Ming Zhang Zhongjian fine ceramics material ultrasonic detection technology research Non-Destructive Testing 6,1993 151-154)
The industry CT method, it gives the tomoscan image of outgoing event, can intuitively see locus, size, the shape of target detail from the image, image is easy to identification and understands, industry CT also has outstanding density resolution, is digitized result, therefrom can directly provide pixel value, physical messages such as size are particularly suitable for the polytype Non-Destructive Testing of compound substance.But industry CT involves great expense, and detection efficiency is quite low, and equipment can reach millions of units, organizes bushing pipe need detect 60 minutes at least for 1 meter high, and these shortcomings have suppressed its testing tool as a kind of suitable type and extensive type greatly.(1:George Y, Baaklinietal X-RayMicrotomography of Ceramic and Metal Matrix Composites Materials Evalution9,1995 1040-1045 2: Ni Peijun, Li Xudong, Peng builds middle industry CT technology Non-Destructive Testing 6,1996 173-176).
The acoustic emission Non-Destructive Testing, be to utilize stress to produce plastic yield at fault location, then the method with electronics receives the stress wave that emits, utilize acoustic emission signal to come defective is forecast and judged, and to the monitoring material estimate, but the shortcoming of acoustic emission is to explain that with difficulty acoustic emission source needs the standard of rich knowledge and signal processing method and cooperating of other laboratory facilities, and the acoustic emission detection environment usually is subjected to the interference of very noisy, and the acoustic emission equipment complexity, these all ring and make it be difficult to detection means as a kind of routine.(Zhang Junzhe DNT technology and applied science publishing house thereof)
Summary of the invention
The object of the invention is to provide a kind of analyser that detects the size and the distribution situation of high resistance lining layer crackle.Be characterized in easy to detect, with low cost.
Formation of the present invention comprises five parts composition, and first is a pressurized equipment, comprises high-pressure pump 1, and its pressure limit is 0-20Mpa, and tunable medium is gas or liquid continuously; Second portion is the electrolytic deposition part, comprise high value inner liner compound pipe 2 to be checked, high resistance lining layer comprises that all are higher than the material of bath resistance rate, for example pottery, enamel, concrete, glass, cast stone, coating, rubber, plastics, resin, paint, fabric etc.Electrode 5, electrolytic solution 6; Electrolytic solution is the electrolytic solution of various platings or alloy, the electrolytic solution of for example copper facing, chromium, nickel, iron, zinc, cobalt and alloy; Third part is to support water-tight equipment, comprises support 3; The 4th part is an automation control appliance, comprises pressure transducer 4, foil gauge 7, strain gauge 8, microcomputer 9, printer 10, current sensor 11, voltage sensor 12; The 5th part is a rectifier 13.
The present invention utilizes electrodeposition process to detect the crackle of high resistance lining layer, original layers is used as negative electrode, in being arranged, the face of lining adds electrolytic solution, the logical direct current of going up, the migration of generation negative ions, oxidation reaction taking place on anode, reduction reaction takes place on negative electrode, thereby deposits product in the cracks of lining.By exerting pressure, after pressure reaches certain value, force crack extesion, thereby can analyze the relation between crack growth and the impressed pressure to high resistance lining layer.
The electric current that produces during electrolysis is directly proportional with the crackle sectional area, and the crackle sectional area is directly proportional with pressure.From last relation of plane, can draw the relation of electric current and pressure, thereby can obtain electric current and pressure dependence figure.Can think pressure one regularly, just can think that the high resistance lining layer product is a waste product when electric current surpasses a certain value.Pass through microprocessor, with pressure, strain, electric current, voltage four road analog signalses, through A D conversion, form the accessible digital quantity of microcomputer, draw the graph of a relation of pressure, strain, electric current, again by D A change the size of controlled pressure, electric current, voltage, thereby the standard that can make various high resistance lining layer crackles sizes and distribute.
The invention has the advantages that:
1. Measuring Time is short, only just can detect with 3-5 minute as the crackle for 1 meter long lined ceramics steel pipe to finish.
2. equipment is simple, easy operating, and expense is low, is specially adapted to the detection means of factory as a kind of routine.
3. by microcomputer data processing, can obtain the crackle size cases, utilize endoscope, can intuitively find out the crack distribution situation.
4. institute's plus-pressure is adjustable continuously, but the relation between detection of dynamic lining crack growth and the impressed pressure.
