The maintenance and upkeep of the xenon lamp aging test chamber should revolve around the "xenon lamp system, measurement and control system, environmental simulation system, and box structure". Regular cleaning, calibration, and replacement of vulnerable parts are necessary to ensure accurate test data and equipment lifespan.
Xenon lamp replacement: The lifespan is usually 1000-2000 hours. If spectral shift or significant decrease in brightness is found during use, it should be replaced immediately; When replacing, turn off the power for cooling and avoid touching the lamp body directly with your hands (grease on your hands can cause the lamp body to burst at high temperatures). Wear dust-free gloves.
Filter cleaning: Clean once a month, gently wipe with anhydrous ethanol dipped in a dust-free cloth (to avoid scratching), remove surface dust and oil stains, and prevent affecting irradiation uniformity.
Lamp holder inspection: Check the wiring terminals of the lamp holder every 3 months to avoid looseness and poor contact; Clean the dust around the lamp holder to prevent high-temperature dust accumulation and spontaneous combustion.
Sensor calibration: Calibrate once every 6 months - irradiance sensor (compared with a standard radiometer), temperature sensor (blackboard temperature, box temperature, calibrated with a standard thermometer), humidity sensor (calibrated with a standard hygrometer). If the calibration is not qualified, replace it in a timely manner.
Controller maintenance: Clean the controller panel monthly and wipe away dust with a dry cloth; Avoid scratching the touch screen with sharp objects; Regularly check the connection wires of the controller to prevent looseness.
Record instrument maintenance: export test data and backup it every month; Check if the instrument display is normal. If there is a data jump, troubleshoot the sensor or circuit issues.
Temperature and humidity system: Clean the humidifier water tank weekly and replace it with purified water (to avoid scale accumulation); Clean the humidity sensor probe monthly (rinse with distilled water and air dry); Check the heating tube and refrigeration compressor every 3 months, clean the dust on the compressor cooling fins (blow them clean with a high-pressure air pipe).
Sprinkler system: Check the sprinkler head weekly and clean the blocked aperture (using a fine needle to clear it); Replace the water in the sprinkler tank every month and clean the scale on the inner wall of the tank; Check whether the water pipes are aging or leaking, and replace damaged pipes in a timely manner.
Condensation system: Clean the condensation coil every 3 months to remove dust and oil stains, ensuring the condensation effect; Check the operation status of the condensate pump to avoid abnormal noise and water leakage.
Box cleaning: After the experiment is completed, wipe the inner wall of the box and the sample rack with a neutral cleaning agent (avoid corrosive cleaning agents), dry and close the box door; Clean the outer shell of the box every month and keep the ventilation and heat dissipation ports unobstructed.
Sample rack maintenance: Check the firmness of the sample rack every 3 months and tighten loose screws; If the sample holder has corrosion (such as contact with corrosive samples), promptly remove rust or replace it.
Safety component inspection: Check the emergency stop button, overload protection switch, and door lock monthly to ensure sensitive pressing and reliable locking; Check the safety valve and pressure gauge (if equipped with a pressure system) every 6 months to avoid safety hazards.
Daily use: Before the experiment, ensure that there are no obstacles around the equipment (leaving more than 30cm of heat dissipation space); Avoid frequent starting and stopping of equipment (with a minimum interval of 3 minutes between each start and stop); Do not test samples that are flammable, explosive, or highly corrosive.
Long term shutdown (more than 1 month): Drain the water from the humidifier and spray water tank; Clean the inside and outside of the equipment, turn off the main power supply; Cover the equipment with a dust cover and place it in a dry, ventilated environment to avoid moisture and rust.
