Equipment concrete function condition and parameter introduction:
The aging test casing:
The aging test casing can be divided into hot and humid system on the function, the system of drenching with rain, salt fog system, illumination system, refrigeration system, and wherein refrigeration system is used in this test.Can use simultaneously between each system, as can be known aging equipment state has the illumination of drenching with rain attitude, hot and humid attitude, xeothermic attitude, high hygrometric state, day with high temperature according to attitude in experimental program design.The illumination attitude of drenching with rain wherein acts on simultaneously by the system of drenching with rain and illumination system exactly to be finished, and day with high temperature also is like this according to attitude.
The aging test casing can be divided into again on structure: casing, adjusting passage, electrical system, refrigeration system.Their function is as follows respectively:
Casing provides the position that other structure is installed and the space of placing test specimen.
Regulate passage and be cold that refrigeration system is produced, heat that well heater produces passes to cabinet space with the mode of forced convertion.Generally be the air blast of passage top, bottom return air.
Electrical system makes their energy normal operations for electrical equipment provides rational circuit.
Refrigeration system is moved needed cold by refrigerating plant generation equipment such as compressor, condenser, restriction device (expansion valve/kapillary), evaporators.
As shown in Figure 2, for the utility model application example aging test casing master looks synoptic diagram, wherein, 21 is centrifugal blower; 22 for observing air regulator; 23 is control panel.As shown in Figure 3, for looking synoptic diagram in the utility model application example aging test casing left side, wherein, 31 are heat conduction resistance; 32 is fairlead.As can be seen from Figure, body structure is:
The outer wall of tank wall is ivory white color steel, and inwall is 316 corrosion resistant plates.Between inside and outside wall, fill polyamine fat vacuole foam and glass wool formation thermofin.
The inner space is that inner front side is the trial target placement space, and inner rear side is air regulating channel.Air regulating channel is made up of centrifugal blower, channel bracket and cover plate etc.The evaporator of well heater and refrigeration system all is positioned at the adjusting channel interior.
2 of electric heating hollow tempering glass windows are installed on the chamber door.All be embedded with heating wire around doorframe, window frame and the box-frame, surface condensation frosting in the time that low-temperature test can being prevented.Fairlead casing left and right sides has fairlead and has 6, and the standard wire bore dia is Φ 100mm.
In process of the test, especially under the situation of illumination attitude, must close window, in order to avoid illumination is too strong, stab the glasses of testing crew.
Illumination system:
The key problem of illumination system performance is the selection of artificial light source and the design of running parameter, and the energy distribution of various artificial light sources and sunshine compare, and xenon lamp spectrum is the most similar with solar spectrum, and the result who obtains and natural atmosphere expose good corresponding relation.Therefore, this equipment has selected the water temperature xenon lamp of 4*6KW to be used as artificial light source, and intensity of sunshine is at 280 ~ 1120W/m
2Adjustable.The design of xenon lamp is divided into horizontal xenon lamp and vertical xenon lamp, mainly is the demand that satisfies the various sample intensity of illumination.
The irradiance measurement of xenon lamp is that the measurement range that adopts casing to carry is 30～300W/cm in the aging equipment
2The spectral irradiance measuring instrument, the xenon lamp irradiance that can directly record is generally at 40～280W/cm
2, the irradiance of indivedual new xenon lamps when system voltage is the highest at night can reach 120W/cm
2Xenon lamp serviceable life is at 500h～1000h, xenon lamp the phenomenon of blackening can occur through after a while use, should in time change fluorescent tube in lamp tube service life in the time, in case because the reason that fluorescent tube blackening or output power descend causes intensity of illumination not enough, test condition does not reach requirement.When it reached serviceable life, irradiance can descend 20～40% rapidly in very short time, in test, generally worked as the xenon lamp irradiance and was down to 40W/cm
2When following, the xenon lamp that should more renew just.When the xenon lamp irradiance at 40-280mW/cm
2The time, test product center surface direct projection power is at 81-98mW/cm
2Scope, with irradiance in the IEC standard at 90W/cm
2About the regulation unanimity.And the tank wall that stainless steel is made to the reflection coefficient of solar radiation about 0.8, in fact the suffered irradiation of test product should be higher than this value.
Because fluorescent tube in use can discharge a large amount of heats, guarantees necessarily during start that recirculated water keeps clear.When long-time the use, the too high reason of cooling temperature of circulating water also can occur, cause fluorescent tube to descend serviceable life, even the phenomenon that bursts.Therefore testing the later stage has been equipped with circulating water cooling device, can effectively control circulating water temperature about 20 ℃, thereby guarantee the intensity of illumination of testing requirements.Recirculated water require to use pure water, because tap water incrustation scale can occur after through the high temperature heating, can stop up water pipe, causes that lamp hole temperature is too high to be burst, and therefore pays particular attention to.
The system of drenching with rain:
The system of drenching with rain mainly is made up of road pump, pumping motor, eight groups of shower nozzles of drenching with rain of the water tank of drenching with rain, adjustable in pressure, and the strength range of drenching with rain is at 1.0～1.5mm/min, and the degree of divergence of each shower nozzle, the spray position is all adjustable.The system of drenching with rain is a simple relatively system, generally cooperates illumination system to use together, in circulations in 24 hours of the design of this testing program, only cooperates illumination to use in circulation in first 2 hours.General artificial weathering test condition commonly used have continuous light to expose and periodically spray water, have light and unglazed alternately expose and periodically water spray, the continuous light of not spraying water expose, do not spray water light is arranged and unglazedly alternately exposes 4 kinds.What this testing program was selected is exactly the 1st kind.
The rainfall density of drenching with rain is adjustable in 1.0～1.5mm/min, considers operating mode in the reality and the requirement of laboratory condition, rainfall control about 1.2mm/min.Rainfall amount is measured and is adopted following method in the reality, when rainfall is stablized, also moves up and down uniformly with the open-top receptacle of diameter 158mm is slow in test product setting height(from bottom) scope, measures the total rainfall amount in 1 minute.Each test product installation site is measured and is averaged for 3 times.It is as shown in table 2 measure to calculate test product position per minute rainfall amount, and No. 1 position is because the most close in-line pump water outlet place, so its rainfall is bigger than other three positions, remaining position rainfall amount is more or less the same.
Rainfall amount measurement result in table 2 salt fog cabinet
