Description
One, technical field:
The present invention relates to a kind of material test instrument, especially relate to a kind of light-radiation ageing device for road surface materials.
Two, background technology:
Still do not have the actual environment for use of simulated roadway material at present both at home and abroad, carry out the equipment of ground surface material light radiation aging test.Scientific research institutions such as 629 of Guangzhou ageing research institutes, Xi'an carried out the discussion of similar aging test, but all were to adopt uviol lamp to come simulated light according to radiative aging, with the aging spectrum of the solar radiation of material reality bigger difference were arranged; The desired condition of experimental facilities is relatively stricter simultaneously, and situation about simulate is limited, has just simulated optical radiation in particular cases and has worn out, and can not simulate the radiative aging under different light intensity or the radiation intensity.These shortcomings make ground surface material optical radiation ageing research be subjected to device-restrictive.
Three, summary of the invention:
The present invention is in order to solve the weak point in the above-mentioned background technology, a kind of light-radiation ageing device for road surface materials is provided, it can simulate the ground surface material optical radiation ageing process of different regions under the full-time light, simulate the aging of material under the different situations by regulating radiation intensity, the most approaching, applied widely with on-site actual situations.
For achieving the above object, the technical solution used in the present invention is:
A kind of light-radiation ageing device for road surface materials, its special character is: comprise casing, be provided with control system in the casing, control system is connected with triggering system, irradiation system and cooling system respectively, and irradiation system is connected with cooling system with triggering system respectively.

Above-mentioned cooling system is the twin-stage cooling system.
Above-mentioned xenon lamp below is provided with can regulate the testing table that highly carries out lifting, and bottom half is equipped with pulley.
Compared with prior art, the advantage and the effect that have of the present invention is as follows:
1, the present invention uses xenon lamp, and solar spectrum and light radiation situation in the actual use of simulated roadway material accurately are the most approaching with on-site actual situations.
2, the present invention is by regulating xenon lamp power, and the optical radiation aging conditions under the simulated roadway material different illumination intensity can be carried out the optical radiation aging test according to the solar irradiation situation of different regions different time, and is applied widely.
Four, description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a concrete principle of work block diagram of the present invention.
Among the figure, 1-casing, 2-xenon lamp, 3-fan, 4-sample bench, 5-cooling tube, 6-twin-stage cooling system, 7-control system.
Five, embodiment:
Referring to Fig. 1, Fig. 2, comprise irradiation system, triggering system, control system 7, cooling system 6 and casing 1 system, be provided with control system 7 in the casing 1, control system 7 is connected with triggering system, irradiation system and cooling system 6 respectively, and irradiation system is connected with cooling system 6 with triggering system respectively.Irradiation system mainly is an xenon lamp 2, is of paramount importance part in the system.Studies show that xenon lamp is the artificial light sources the most approaching with daylight, can simulated solar irradiation spectrum.Triggering system changes to high pressure by transformer from low pressure and excites xenon lamp 2, and atom is excited to high energy level under hyperbar, and by a large amount of ionization, just launches continuous spectrum.Control system 7 is to be used for controlling overall optical according to the radiative aging system, it is the core, control the exciting of xenon lamp 2, intensity variations by it, come Control Circulation cooling system 6 by pressure transducer, cooling-water temperature sensor simultaneously, guarantee that total system moves safely and efficiently.Cooling system 6 cools off fluorescent tube by the twin-stage water-cooled, come the cooling work environment with fan 3, reject the influence of humidity, temperature, make the single factor effect of optical radiation not disturbed by the influence of other non-mainstream factors, use the air-cooled safety that whole experimental system guarantees system of cooling off in addition sample.Box system is used for holding above assembly, and top is the aging test operating room, and the bottom is an electric control system 7.
Xenon lamp 2 and reflection lampshade are installed in casing 1 center of top and join by external cable and control system 7, the liquid coolant of cooling fluorescent tube also links to each other with fluorescent tube by cooling tube, meanwhile, 3 pairs of working box coolings of cooling fan are arranged at casing 1 top, testing table 4 in the operating room can be regulated and highly carry out lifting, to obtain different intensities of illumination.After liquid coolant flows through fluorescent tube, flow back into twin-stage cooling system 6, after supercooling, continue circulation cooling xenon lamp 2 again.Pulley is equipped with in whole box body 1 bottom, moves with convenient.
Principle of work of the present invention and process:
(1) principle of work:
Studies show that xenon lamp is the artificial light sources the most approaching with daylight, can simulated solar irradiation, so adopt xenon lamp as artificially-aged light source.The concrete principle of work of light-radiation ageing device for road surface materials as shown in Figure 2.
Control whole instrument by control system 7; opening power; be that 7 systems become the normal pressure power supply high pressure that needs and carry out voltage stabilizing by transformer by control earlier; excite instantaneous pressure to trigger xenon lamp 2 by triggering system afterwards; after triggering successfully; continuation is powered to xenon lamp 2 by control section; stablize irradiation system; meanwhile; 7 pairs of cooling systems 6 of control system are controlled, monitoring cooling system variation of temperature, thereby and the circulatory condition of liquid coolant guarantee that instrument turns round normally; 6 modes of cooling off with twin-stage of cooling system are protected xenon lamp 2 to the irradiation system cools.By regulation and control system 7 different capacity gears, obtain the different operating power of xenon lamp 2, thereby obtain different intensities of illumination, simulate the optical radiation situation in different time, area.
(2) course of work:
At first, open cooling system 6, allow chilled water circulate, energized turns on the power switch afterwards, and whether current, outer water flow pressure and water temperature be normal in observing, and is working properly to confirm cooling system 6, triggers xenon lamp 2 under all normal situations.Control system 7 has different gears, can realize simulating than the light radiation under the big-difference from low to high, mainly regulate the power of xenon lamp by the voltage and current of regulating xenon lamp 2, thereby regulate the radiation intensity of the light of xenon lamp 2, so just can simulate the light aging phenomenon under the different illumination intensity of different regions easily.Sample bench 4 is arranged in work box, can under same gear, regulate different intensities of illumination, realize fine setting by regulating differing heights.By to the actual meteorological data analysis that simulated the area, obtain light radiation intensity on the spot, the chamber is regulated simulated field illumination on the spot or quickens optical radiation aging by experiment then.Two hydraulic pressure switches are arranged in the cooling system, the water delivering orifice of current and outer current in laying respectively at, in case when anhydrous, xenon lamp 2 working temperatures are too high and damage.Simultaneously in interior current temperature sensor is arranged, collecting temperature again by the working temperature of control system 7 control xenon lamps 2, guarantees the safety of experiment.Other has, and 3 pairs of experiment casings of extraction fan 1 carry out exhaust cooling.
