Kailang high and low temperature maintenance of a method <br> <br>, high and low temperature and humidity chamber are important factors affecting the performance of the instrument, which can cause corrosion of mechanical components, so that the metal mirror surface smoothness decreases, causing high The error or performance of the mechanical part of the low temperature test chamber is degraded; the aluminum film of the high and low temperature test chamber optical components such as gratings, mirrors, focusing mirrors, etc. is rusted, resulting in insufficient light energy, stray light, noise, etc., even the instrument stops working, thus affecting The life of the high and low temperature test chamber should be corrected regularly during maintenance.
Second, the reasons for the frosting of the evaporator of the high and low temperature test chamber: (1) often open the test box door (2) check whether the box has air leakage. 3. After using a certain period of high and low temperature test chamber, the internal will accumulate a certain amount. Dust, the maintenance engineer or the engineer to open the high and low temperature test chamber cover regularly to carry out the dust removal work, and at the same time re-tighten the heat sink of each heating element, clean the sealing window of the optical box, if necessary Calibrate, clean the mechanical parts and necessary lubrication, and then restore the original condition, and then carry out some necessary testing, adjustment and recording.
4. Dust and corrosive gases in the working environment of high and low temperature test chambers can also affect the flexibility of mechanical systems, reduce the reliability of various limit switches, buttons and photoelectric couplers, and also cause the corrosion of aluminum film of components. one.
