Explain how to prevent and solve the problem that the door of the high and low temperature alternating heat and humidity test chamber cannot be closed.
The high-low temperature alternating heat and humidity test chamber industry has become more and more popular with the development of China's industrial enterprises, and the demand for this equipment in the market is also growing. However, users' requirements for equipment are becoming more and more strict, not only to ensure the high cost performance of the equipment, but also to ensure the quality and service life of the equipment. I believe everyone knows that the test box is a non-consumable test instrument, but do you know which parts are often bad or easy to break?
It doesn't look so serious that the door can't be closed. However, this is a very serious problem for the equipment with strict sealing requirements, such as the high-low temperature alternating heat and humidity test chamber. If it is not solved, the equipment will not be able to. Continuing the test, even if the test is forcibly carried out, there is no guarantee that the test results will be correct. So inquire about the test box manufacturer in case of such problems, but in order to save time, we can first understand what the door can not be closed.
In fact, the main reason why Xiaobian personally feels that the door of the equipment can not be closed is that the sealing strip is aging and deformed due to long-term use. If it is not particularly serious, you can try the hot air setting and hot water soaking method. Before you must find the manufacturer to understand the specific operation method, to avoid the deformation of the sealing strip is more serious because you do not understand the operation method.
Of course, if the seal of the high-temperature and low-temperature alternating heat and humidity test chamber is seriously damaged, let the technicians of the factory come and bring better seals and corresponding tools, which can save a lot of time and allow the user to operate the test equipment as soon as possible. test. However, if it is not caused by deformation and aging of the sealing strip, then it must be handled by the technicians and cannot be solved without authorization. Otherwise, more serious problems may occur, and the safety of the operators and equipment may not be guaranteed. In fact, if you don't want the aging of the high temperature and low temperature alternating heat and humidity test box seals, then daily maintenance is also very important.
Maintenance knowledge of Haotian high and low temperature alternating heat and humidity test chamber products:
1. Temperature and humidity are important factors affecting the performance of the instrument, which can cause corrosion of mechanical parts, reduce the smoothness of the metal mirror surface, and reduce the error or performance of the mechanical part of the test box; causing the optical components of the test box such as gratings, mirrors, The aluminum film of the focusing mirror is rusted, resulting in insufficient light energy, stray light, noise, etc., and even the instrument stops working, thereby affecting the life of the test box, and should be regularly corrected during maintenance.
2. After a certain period of use of the test box, a certain amount of dust will accumulate inside. The maintenance engineer or the engineer will open the test box cover regularly to carry out dust removal work, and re-fasten the heat sink of each heating element to optics. The sealed window of the box is cleaned and calibrated if necessary. The mechanical parts of the high-low temperature alternating heat and humidity test chamber of the Haotian are cleaned and necessaryly lubricated, and the original state is restored, and then necessary detection, adjustment and recording are carried out.
