Extensive use of high and low temperature test chambers in industry

High and low temperature test chamber products have temperature and humidity conditions in the atmospheric environment. It is mainly aimed at the adaptability test of electricians, electronic products, their components, and other materials when they are transported and used in a comprehensive environment of high temperature, humidity, and low temperature.

With the development of China's modern industrial products and the development of science and technology, the application of high and low temperature test chambers is becoming more and more widely used, and the requirements for production and scientific research are becoming higher and higher. It is required to have a higher performance-to-price ratio, longer service life, less use cost (power saving), and faster response speed.

The high and low temperature test chamber is used for the reliability test of high and low temperature of industrial products. For the components and materials of electronic products, automobile motorcycles, aerospace, marine weapons, colleges and universities, scientific research units and other related products under high and low temperature cycle changes, check each performance index. The product has a wide temperature control range, and its performance indicators have reached the national standard GB10592-89 high and low temperature test chamber technical conditions, which is applicable to the environmental test of electrical and electronic products A: Low temperature test method and test B: High temperature test method "conducts low temperature, high temperature test and constant temperature test on the product. Products comply with GB2423.1, GB2423.2, GJB150.3, GJB150.4, IEC, MIL standards.

When the high and low temperature test chamber products are researched and developed in environmental adaptability test equipment, we follow the objective laws and make them with strict standards. So as to ensure that the equipment is determined, reliable and practical to produce high-quality equipment for customers.

Our high-low temperature test chamber is generally recommended to be placed in a temperature range of 8 ℃ ~ 28 ℃. For laboratories that do not have this condition, appropriate air conditioners must be equipped. Adhere to the professional management and maintenance of special personnel. Qualified units should send special personnel to the supplier's factory for training and learning from time to time to obtain professional maintenance and repair experience and capabilities. The condenser is cleaned once every three months. If the compressor is cooled by air, the condenser fan should be regularly repaired and the condenser should be decontaminated and dedusted to ensure good ventilation and heat exchange performance.

For compressors using water cooling, in addition to ensuring the inlet water pressure and inlet water temperature, the corresponding flow rate must also be guaranteed, and the inside of the condenser should be cleaned and descaled regularly to obtain its continuous heat exchange performance.

The high and low temperature test chamber also needs to clean the evaporator regularly, because the cleanliness of the samples varies, and a lot of dust and small particles will condense on the evaporator under the action of forced air circulation, so it should be cleaned regularly. There are also waterway and humidifier cleaning. If the waterway is not smooth and the humidifier is fouled, it will cause the humidifier to dry and burn and damage the humidifier. Therefore, the waterway and humidifier must be cleaned regularly. It is also necessary to set the temperature around the ambient temperature after each test is completed, cut off the power supply after working for about 30 minutes, and then clean the interior wall of the working room. When the machine is not used for a long period of time, the product must be regularly energized every half a month, and the energization time should not be less than 1 hour.

Because the price of high and low temperature test chamber is basically composed of electrical, refrigeration and mechanical systems. Therefore, once there is a problem with the equipment, it is necessary to comprehensively check and comprehensively analyze the entire equipment system. Generally speaking, the process of analysis and judgment can be carried out first, after the external factors are eliminated first, and then the system is decomposed based on the fundamental fault phenomenon. After the comprehensive analysis and judgment of the system, or you can also use the backward method to find the cause of the failure. First, check whether there is a problem with the electrical system according to the electrical wiring diagram, and finally find out whether it is a problem with the refrigeration system. Before you can understand the cause of the failure, you must not blindly disassemble or replace parts to avoid unnecessary trouble.
