Xenon lamp weathering test chamber xenon lamp lamp will be accompanied by the application of time to increase the irradiance compressive intensity decreases, and the service life of the xenon lamp lamp is now attributed to the xenon lamp weather test chamber consumables, so the xenon lamp tube in its irradiance compressive strength must be dismantled, the following is the commonly used domestic air-cooled xenon lamp weathering test chamber lamp replacement process
.
The first step: turn off the main switching power supply of the test chamber and remove the back cover plate
at the top of the machine and equipment.
Step 2: Remove the insulation plates of the three lamp covers separately to fix the screws
.
Step 3: After removing the copper screw nuts that hold the lamp tube in place, release the nuts on both sides of the lamp tube and remove the lamp
.
The fourth step: because the lamp belongs to the air-cooled type, the heat dissipation of the lamp tube is driven by the blower motor to the relative water-cooled gas charge of the lamp cover into the lamp cover to bring away the heat on the surface of the lamp, and the cooling air after charging will also bring a certain amount of dust, and after accumulating a period of time, the dust will adhere to the surface of the filter to reduce the penetration rate of light, and the other adhesion to the surface of the lamp will endanger the heat dissipation
of the lamp tube.
Therefore, according to the office environment of the test chamber on the spot, the lamp and filter
are scrubbed on time.
Carry opalescent rubber gloves with you and scrub both sides of the filter with medical alcohol and dust-free paper with a concentration value of 5%, and the surface
of its lamp.
Step 5: After installing three lamps for this, twist and tighten the wiring head, cover the insulation plate, and tighten the screws
.
Step 6: Turn on the switching power supply of the test chamber and test the radiation compressive strength
.
