First, the temperature and humidity of the high and low temperature test chamber are important factors affecting the performance of the instrument, which can cause the corrosion of mechanical parts, reduce the smoothness of the metal mirror surface, cause the error or performance degradation of the mechanical part of the high and low temperature test chamber; The optical components of the box optical components such as gratings, mirrors, focusing mirrors, etc. are rusted, resulting in insufficient light energy, stray light, noise, etc., and even the instrument stops working, thereby affecting the life of the high and low temperature test chambers, and should be regularly corrected during maintenance.
Second, the dust and corrosive gases in the working environment of the high and low temperature test chamber can also affect the flexibility of the mechanical system, reduce the reliability of various limit switches, buttons and photoelectric couplers, and also cause the corrosion of the aluminum film of the components. one.
3. After using a certain period of high and low temperature test chamber, a certain amount of dust will accumulate inside. The maintenance engineer or the engineer will open the high and low temperature test chamber cover regularly to carry out dust removal work, and at the same time, the heat sink of each heating element. Re-tighten, clean the sealing window of the optical box, calibrate it if necessary, clean the mechanical parts and necessary lubrication, and then restore the original shape, and then carry out some necessary testing, adjustment and recording.
Fourth, the reason for the evaporator frost in the high and low temperature test chamber: (1) often open the test box door (2) to check whether the box has air leakage problems.
