Daily maintenance of high and low temperature test chamber

by:Sure     2021-08-18
Analytical instrument workers must understand the daily maintenance of the instrument and the simple test methods of the main technical indicators, and they often maintain and test the instrument to ensure that the instrument is working in the best condition. 1. Dust and corrosive gases in the environment can also affect the flexibility of the mechanical system, reduce the reliability of various limit switches, buttons, and photoelectric couplings. It also makes it necessary for the analytical instrument workers of the Faculty to understand the daily maintenance of the instrument. And the simple test method for the main technical indicators, I often maintain and test the instrument to ensure that the instrument works in the best condition. 1. Dust and corrosive gases in the environment can also affect the flexibility of the mechanical system, reduce the reliability of various limit switches, buttons, and photoelectric couplings, and it is also one of the reasons for the rust of the aluminum film of the necessary parts. Therefore, it must be cleaned regularly to protect the environment and indoor sanitary conditions of the instrument and prevent dust. . 2. After the high and low temperature test box is used for a certain period of time, a certain amount of dust will accumulate inside. It is best to have the maintenance engineer or under the guidance of the engineer regularly open the instrument cover to remove the internal dust, and re-fasten the radiators of the heating elements , Clean the sealing window of the optical box, calibrate the optical path if necessary, clean the mechanical parts and lubricate the mechanical parts, and finally restore the original state, and then perform some necessary inspections, adjustments and records. 3. Temperature and humidity are important factors affecting the performance of high and low temperature test chambers. They can cause the corrosion of mechanical parts, reduce the finish of the metal mirror, cause errors or performance degradation of the mechanical parts of the instrument; cause the aluminum film of optical parts such as gratings, reflectors, focusing mirrors, etc. to rust, resulting in insufficient light energy, stray light, Noise, etc., even the instrument stops working, thereby affecting the life of the instrument. The high and low temperature test chamber should be calibrated regularly when maintaining it. There should be an instrument room with four seasons and constant humidity, equipped with constant temperature equipment, especially laboratories located in the southern region.
