Description
Technical field:
The utility model relates to a kind of testing equipment, relates in particular to a kind of salt-mist corrosion tester.
Background technology:
In people's living environment, be flooded with a large amount of in the air because the saliferous steam that marine motor causes, salt in these saliferous steam be adsorbed on the protective layer of parts, electronic element, metal material and the industrial products can and its generation chemical reaction produce corrosive attack, the Related product production run excessively in, corrosion resistivity test just seems particularly important.
Salt-mist corrosion tester is mainly used in simulating ocean climate as a kind of experimental facilities, is used for the performance of the salt fog resistance corrosion of examination material, product and protective layer thereof, and the processing quality of estimating protective layer.Existing salt-mist corrosion tester has following shortcoming:
1. the salt fog settling amount in traditional salt spray corrosion test is normally realized by adjustable spraying pressure, but this regulative mode form is single, and the control effect also has very large relation with the performance of external air compressor;
2. the ejection angle of the position of salt spray generator and salt fog is non-adjustable in traditional salt spray corrosion test, salt fog may occur and inject directly on situation on the test specimen, sample directly is subject to the part meeting accelerated corrosion of salt spray, so that salt-fog test result's accuracy can not get ensureing;
3. the time of salt spray corrosion test is often longer, the testing crew real time status of viewing test sample intuitively in test, when testing crew is wanted the situation of check test sample, need first abort, then open chamber viewing test sample, then proceed test, but because the process of observing has interrupted the continuity of test, destroyed the ratio of chamber composition of gases within, the accuracy of testing has been caused certain influence;
4. the sealing means of salt-mist corrosion tester generally all adopts rubber seal, because rubber uses temperature distortion for a long time, its sealing property descends, and test reliability reduces.
Summary of the invention:
The purpose of this utility model provides a kind of salt-mist corrosion tester.It is simple in structure, easy to operate, and test effect is good.
The technical scheme of a kind of salt-mist corrosion tester described in the utility model is achieved in that
A kind of salt-mist corrosion tester, it comprises brine tank, for generation of saturated bucket and the operating room of water vapor, is provided with a mist generating device in the operating room, it is characterized in that: described mist generating device comprises:
One housing, the housing outer wall is provided with a fastener, and operating room's inwall forms a draw-in groove in the fastener corresponding position, and housing is connected on the draw-in groove by fastener and can slides at draw-in groove, forms the accommodating cavity with an opening in the described housing;
Be arranged at a water vapor shower nozzle and a salt sprinkler head in the accommodating cavity, the water vapor shower nozzle is connected with saturated barrel, and the salt sprinkler head is connected with brine tank, the salt solution that the water vapor that the water vapor shower nozzle sprays and salt sprinkler head the spray formation salt fog that crosses after ejaculation;
One end is articulated in a spraying baffle plate of this accommodating cavity opening part.
The described a kind of salt-mist corrosion tester of the utility model utility model compared with prior art has following advantage:
1. the settling amount of salt fog is not only regulated by atomisation pressure, and can control by the angle of spraying baffle plate, when spraying baffle plate hinge angle is larger, it is large that the opening of accommodating cavity becomes, and the salt fog output quantity of salt spray generator increases, so that the salt fog settling amount rises in the operating room, when spraying baffle plate hinge angle hour, the openings get smaller of accommodating cavity, the salt fog input quantity of salt spray generator reduces, so that the salt fog settling amount descends in the operating room.Adopt dual mode control salt fog settling amount, the control better effects if;
2. the emission direction of salt fog can be regulated according to the hinge angle of spraying baffle plate is different, during test, can regulate the hinge angle of baffle plate according to the volume size of test specimen, be beneficial to salt fog and be evenly distributed in around the test specimen, improve test reliability;
3. salt spray generator can slide at draw-in groove by fastener, to adjust the position of salt spray generator, testing crew can be adjusted the position of salt spray generator by testing requirements, avoids the salt fog of salt spray generator to be directly injected on the test specimen, affects test effect.
Water vapor shower nozzle described above arranges straight up, and the salt sprinkler head is horizontally disposed with, and described accommodating cavity opening is positioned at the top of accommodating cavity.The pressure of water vapor shower nozzle is greater than the salt solution sprinkler pressure, and the salt fog that water vapor and salt solution form flows to the opening of accommodating cavity, and opening is positioned at the accommodating cavity top, so that effectively sedimentation of the salt fog in the operating room.
Accommodating cavity described above bottom also is provided with an overflow pipe, and the height of overflow pipe is lower than the height of water vapor shower nozzle.Accommodating cavity bottom surface ponding covered the generation that the saturated vapor shower nozzle affects salt fog after overflow pipe can prevent long-time test.
Operating room described above comprises casing and case lid, and mist generating device is arranged in the casing; Described casing is provided with the watertight sealing groove, and each base of case lid is fastened in the watertight sealing groove of casing.Salt fog was not revealed when the mode of employing water-stop can not cause test because of ageing equipment, did not affect the salt spray corrosion test result.
Case lid described above is transparent material.When the case lid of transparent material was conducive to test, the situation of the viewing test sample that testing crew can be real-time did not need the inspection of uncapping, and makes test findings more accurately and reliably.
