Necessary conditions for quality reliability of high and low temperature alternating wet heat cycle test chamber
Necessary conditions for quality reliability of high and low temperature alternating wet heat cycle test chamber 1) The production of temperature and humidity environmental test equipment is a mechanical manufacturing industry that has lasted for several decades, and its basic technologies (such as refrigeration and heating) have matured. With the advancement and development of industrial technology, many new application technologies are continuously introduced into environmental test equipment, such as computer technology, fuzzy control theory, multi-box synchronous operation, etc., therefore, it is difficult to give manufacturers a better advantage. Inferior arbitrary conclusions. The equipment produced by each manufacturer with decades of manufacturing experience can be used. The working principle, the applied technology, and even the structure and materials have many similarities. However, due to the constraints of the production methods of environmental test equipment “multi-non-standard, multi-variety, small batchâ€, the reliability of the product has always been a problem for domestic and foreign manufacturers. The key is that the manufacturer must manage fine, complete technology, complete testing means, and be responsible for quality (such as ISO9000 certification). At the same time, environmental testing equipment is a durable product. Some problems and design defects need to be exposed for many years to be exposed. Statistical analysis can find out the problem. A mature, highly reliable product often requires years of improvement and improvement. Therefore, environmental test equipment manufacturers have a certain production scale and production history, which is one of the necessary conditions for products with high reliability.

2) Quality control of the production process. The quality control of the domestic production process has been greatly improved. The quality control of the production process is related to the management level and production habits of the manufacturer. The demonstration by ISO9000 is a sign that the quality control of the production process is on the standardization. Manufacturers of temperature and humidity environmental test equipment at home and abroad have accumulated rich experience in the production of climate environment tests. All are available for use and are reliable in quality. As for which one should be selected, which type of product is more in line with the requirements, in addition to some of the principles and specific technical indicators mentioned earlier in this article, there are some factors that should be valued and considered.
a) Performance / price ratio. On the basis of fully researching the technical parameters and reliability of environmental test equipment, cost performance is an important factor that should be considered. The import of environmental test equipment is sold in China through agents. The price factor depends not only on the cost and profit of the manufacturer, but also on the cost of the intermediate link and the sales commission. Under the same manufacturing cost, lowering the intermediate cost is an important factor to reduce the order price. The products with the relevant technical indicators in the same country have the same manufacturing cost. The products produced by different countries (referring to developed countries in the West) will not be too big even if there is a difference. .
b) The degree and ability to meet user needs. The user orders a temperature and humidity environmental test chamber, the requirements of which vary according to the needs of the product test. If any three comprehensive test chambers are often used for product components or components and environmental stress screening tests, the forced dehumidification capacity and additional air of the equipment The possibility of drying the system is the project that the user should focus on. If some users want to use the three comprehensive test chambers for environmental tests (such as damp heat test), wind speed adjustability is a factor that must be considered.
C) The ability to handle after-sales service and equipment failure. It is impossible for any one device to fail during use. If there is a problem, the user can enjoy timely maintenance service, or can quickly determine the fault handling method according to the fault diagnosis capability of the device, so that the device can resume performance as soon as possible. , put it back into use. In this regard, domestic and foreign manufacturers have been or are making active efforts, such as the establishment of a rapid response maintenance team, such as the addition of diagnostic and fault warning system software in the computer control system, users can be based on the information provided by the computer as soon as possible Handle the fault.
