Analysis of Temperature and Humidity Equipment in High and Low Temperature Circulating Tank

時間:2019-09-20 18:03:25

1) The production of temperature and humidity environment test equipment has lasted for decades in the machinery manufacturing industry, and its basic technology (such as refrigeration, heating) has matured. With the progress and development of industrial technology, many new application technologies have been introduced into environmental testing equipment, such as computer technology, fuzzy control theory, multi-box synchronous operation and so on. Therefore, it is difficult to give the manufacturer an arbitrary conclusion of which is better or worse. The equipment manufactured by each manufacturer with decades of manufacturing experience can be used. Its working principle, applied technology, constant temperature water tank and even structure, material have many similarities. However, due to the restriction of the production mode of environmental testing equipment "multi-non-standard, multi-variety and small batch", the reliability of products has always been a problem that troubles domestic and foreign manufacturers. The key is that the manufacturer must have fine management, complete technology, complete testing means, and be responsible for the quality (such as through the ISO9000 demonstration). At the same time, environmental testing equipment is a kind of durable goods, some problems and design defects need years of use to expose, through statistical analysis to find the problem. A mature and highly reliable product often needs years of improvement and perfection. Therefore, environmental test equipment manufacturers have a certain production scale and production history, which is one of the necessary conditions for high reliability of products.




2) Quality control of production process. The quality control of domestic production process has been greatly improved. The quality control of production process is related to the management level and production habit of the manufacturer. The demonstration of ISO9000 is a sign that the quality control of production process is standardized.


Domestic and foreign manufacturers of temperature and humidity environmental testing equipment have accumulated rich experience in the production of climate and environmental testing. The water bath oscillator is reliable in quality. As for which one should be chosen and which type of product is more in line with the requirements, besides some principles and specific technical indicators mentioned above, there are still some factors worthy of attention and consideration.


A) Performance/price ratio.


On the basis of fully verifying the technical parameters and reliability of environmental testing equipment, cost performance ratio is an important factor to be considered. The import of environmental testing equipment is no exception sold through agents in China. The price factor not only depends on the cost and profit of the manufacturer, but also includes many intermediate costs and sales commissions. Under the same manufacturing cost, reducing the intermediate cost is an important factor to reduce the order price. The manufacturing cost of the products with the same country's relevant technical indicators is roughly the same, and the products produced by different countries (referring to western developed countries) will not be too different.


B) The degree and ability to meet the needs of users.


Users order a temperature and humidity environment test box, whose requirements vary according to the needs of product test. If there are three comprehensive test boxes, which are often used for product components or components and environmental stress screening tests, then the forced dehumidification ability of the equipment and the possibility of additional air drying system are the key concerns of users, such as If some users want to use three comprehensive test boxes for environmental testing (such as humidity and heat test), then the adjustability of wind speed is the factor that must be considered.


C) After-sales service and equipment failure handling capacity.
