High and low temperature chambers have a wide range of applications in industrial production, and this instrument is suitable for reliability testing of industrial products at high and low temperatures. Inspect the performance indicators of components and materials of electronic and electrical products, automobiles and motorcycles, aerospace, marine weapons, universities, research institutions and other related products under high and low temperature (alternating) cyclic changes. How to maintain and repair high and low temperature boxes:

1. The temperature and humidity in the high and low temperature laboratory are important factors affecting device performance, which may cause mechanical component corrosion, metal mirror corrosion, and high and low temperature mechanical wear, leading to errors or performance degradation; Under high and low temperature conditions, optical components such as Shiyan gratings in Zaocheng are susceptible to corrosion in temperature controlled electron microscopes, focusing lenses, aluminum, and other materials due to insufficient light, stray light, noise, and even equipment shutdown, which can affect high and low temperatures. Regular corrections should be made to maintain life.

2. After a period of use at high and low temperatures, the Ministry of the Interior will accumulate guidance from engineers to use an electric constant temperature drying oven for dust, or through regular maintenance, engineers will convert a certain amount of work into dust jackets within the high and low temperature range. The radiator will be re tightened with heating elements, the sealed optical frame window will be cleaned, and if necessary, calibrated, mechanical parts will be cleaned and lubricated. Finally, the equipment will be restored to its original state, and necessary inspections, adjustments, and records will be made.

3. In high and low temperature working environments, dust and corrosive gases can also affect the flexibility of mechanical systems, reducing the use of limit switches and buttons. The reliability of optical coupling is one of the reasons for research caused by corrosion of aluminum components.
