Technical field
The utility model belongs to testing techniques of equipment field, is specifically related to a kind of storage tank bottom plate corrosion acoustic emission detection system.
Background technology
Storage tank, as a kind of static equipment of oil, chemical industry storage medium, is widely used, but when applying, storage tank bottom plate more easily galvanic corrosion occurs, and extent of corrosion is more serious than tank skin, sometimes even can produce corrosion failure and occur the phenomenon of leakage of oil.Not easily check repairing at the bottom of tank, be again the position that corrosion easily occurs, anticorrosive paint during base plate welding near weld seam is often burnt again, and this just further increases the seriousness of corrosion.Tank body is except more perishable near weld seam, and the position also holding corrosion-vulnerable of periphery, if tank body surrounding does not seal very well with pitch, dripping that rainwater or suitable tube wall stay is easy to invade the peripheral part at the bottom of tank, makes it form favourable etching condition.According to the actual fact, at the bottom of tank, the corrosion condition of base plate is modal, is also the most serious, and according to relevant Investigation on Data analysis, in the tank stoppage in transit that crude oil storage tank causes because of corrosion leakage of oil, Corrosion of base plate accounts for 76.4%.
At present storage tank bottom plate is generally adopted to the detection mode of site work stopping production, can opening.There is the shortcomings such as cost is high, detection time is long in such storage tank inspection and repair.The duration detecting a large-scale atmospheric storage tank generally can reach tens days even several months.Due to the impact of above-mentioned factor, regularly carry out that field tank detection difficulty is comparatively large, impact safety in production, scene often lacks again effective according to judging whether to need to carry out can opening detection, causes manpower, financial resource to waste.
Utility model content
The utility model provides a kind of storage tank bottom plate corrosion acoustic emission detection system, not only facilitate the location of multiple acoustic emission detection sensor along storage tank outer wall circumferencial direction, and facilitate getting and putting of acoustic emission detection sensor, thus reach Fast Installation sensor, the effect of Measurement accuracy signal.
In order to solve the problem, the technical scheme that the utility model adopts is such, a kind of storage tank bottom plate corrosion acoustic emission detection system, comprise and be adsorbed on acoustic emission detection sensor near storage tank bottom by magnetic support, by the acoustic emission detector that data line is connected with described acoustic emission detection sensor, the display that detector is connected for showing described acoustic emission detector record analysis result is examined with described acoustic emission, described magnetic support comprises the cranse be enclosed near storage tank bottom, the mode that described cranse is removably connected by two semicircle garter springs is spliced, along the uniform 2-6 of cranse circumferencial direction acoustic emission detection sensor cavity volume, sensor cavity volume is the cylindrical shape of both ends open, the position that cranse is provided with sensor cavity volume offers the through hole communicated with sensor cavity volume, the anterior sidewall of sensor cavity volume has the metallic channel of " ∩ " type, top is provided with spring capping, sensor cavity volume lateral wall is symmetrically arranged with a pair stud, stud is through the through hole that arranges corresponding on spring capping lid thus spring capping is fixed on the top of sensor cavity volume.
In order to better cranse is placed on storage tank bottom, not easily landing, described cranse lateral surface is circumferentially gone up the multiple magnet piece of clamping.
Preferably, the equal Vertical dimension extension of both ends of the surface of described semicircle garter spring forms two flangings, described flanging is equipped with bolt hole, bolt passes the bolt hole on two semicircle garter spring flangings thus two semicircle garter springs is fixedly spliced into a cranse, it is more stable that the mode removably connected like this makes two semicircle garter springs connect, not easily landing.
Preferably, described cranse and sensor cavity volume one-body molded.
Beneficial effect:
1, the utility model achieves when not tank switching and clear tank, utilizes acoustic emission to carry out on-line monitoring, realizes storage tank bottom plate Corrosion monitoring, save time very much, laborsaving.
2, acoustic emission detection sensor cavity volume of the present utility model is distributed on cranse circumferencial direction, thus the location of multiple acoustic emission detection sensor along storage tank outer wall circumferencial direction is facilitated, in addition, because spring capping and acoustic emission detection sensor cavity volume are bolted, acoustic emission detection sensor is when placing, first can fix cranse, the acoustic emission detection sensor cavity volume on cranse put into by acoustic emission detection sensor, then spring capping is pressed on acoustic emission detection sensor, by stud, spring capping and sensor cavity volume are fixed again, facilitate getting and putting of acoustic emission detection sensor, thus reach Fast Installation sensor, the effect of Measurement accuracy signal.
