Correct Replacement of Lamp Tube in UV Aging Test Chamber
UV-light weather resistance test chamber adopts fluorescent uv lamp as the light source, through simulating ultraviolet radiation and condensation in natural sunlight, the material is tested for accelerated weatherability, so as to obtain the result of weatherability of the material.The UV aging test chamber is equipped with 8 domestic or imported UV fluorescent tubes of 40W rated power, which are distributed on both sides of the machine, 4 for each side.
Since the energy output of fluorescent lighting will gradually decline with time, in order to reduce the impact of the experiment caused by the attenuation of light energy, the UV aging test chamber will replace an old lamp by a new one when every 1/4 of the lifetime of the fluorescent lamp is separated in all eight lamp tubes.
Replace the tubes in ultraviolet aging test chamber shall be successive change, change the way remove 3 # lamp, 2 # tube moves to the position of the 3 #, 1 # tube moves to the position of the 2 #, 4 # tube moves to the position of the 1 #, 1 in 4 # the location of the bulb installed a new lamp, in this way, ultraviolet light source is composed of the new lamp and old lamps, resulting in a constant output of light energy.
Special tip: pay attention to the surrounding cleaning when replacing the fluorescent lamp. The fluorescent lamp must be installed in parallel with the center distance of 70mm.Correct replacement and maintenance methods can extend the service life of the machine.
