Abstract: Yashilin brand high and low temperature test chamber is suitable for high and low temperature reliability tests of industrial products. For the components and materials of related products of electronic and electrical engineering, automobile and motorcycle, aerospace, ship weaponry, colleges and universities, scientific research units, etc., under the condition of high and low temperature (alternating) cycle changes, check each performance index. The product has a wide temperature control range. 1. Structure of high and low temperature test chamber The box body of the high and low temperature box is processed and formed by CNC machine tool, which has a beautiful and elegant shape, and adopts a non-reaction handle, which is easy to operate; Appearance texture and cleanliness; large observation window with lighting lamp to keep the box bright, and the use of tempered glass embedded in the heating body to clearly observe the situation in the box at any time; the bottom of the machine uses high-quality fixed PU movable wheels; box left The side is equipped with a test hole with a diameter of 50mm, which can be used for an external test power line or signal line. 2. Standard of high and low temperature test chamber The performance indexes of the high and low temperature test chambers have reached the national standard GB10592-89 high and low temperature test chamber technical conditions, which are applicable to the environmental testing of electrical and electronic products A: low temperature test method, test B: high temperature test method according to GB2423.1, GB2423.2 》 Low temperature and high temperature test and constant temperature test are carried out on the product. Products comply with GB2423.1, GB2423.2, GJB150.3, GJB150.4, IEC, MIL standards. 3. Maintenance of high and low temperature test chamber 1. The ground around and at the bottom of the fuselage should be kept clean at all times; 2. Before operating the machine, the internal impurities (objects) should be removed; the laboratory should be cleaned at least once a year; 3. The refrigeration system is the core of the high and low temperature testing machine. It is necessary to inspect all copper pipes for leaks once every six months. All functional joints and welding ports, if there is oil leakage, must be dealt with immediately; 4. The condenser should be maintained regularly to keep it clean. The dusty sticky condenser will cause the compressor high-pressure switch to trip and generate false alarms. The condenser should be maintained regularly on a monthly basis. Use a vacuum cleaner to absorb the dust attached to the condenser cooling mesh or use a hard brush after starting Brush or blow off the dust with a high-pressure air nozzle. 5. At the end of each test, it is recommended to clean the test box with clean water to keep the equipment clean; after the box is clean, the box should be dried to keep the box dry; 6. The circuit breaker and over-temperature protector provide the safety of the local test product and the operator, so please check it regularly; Beauty Injections,All Around Beauty Injections,Types Of Beauty Injections,Cosmetic Beauty Injections Yanbian Nabalu E-commerce Co., Ltd. , https://www.nabalubeauty.com
