Hot and cold impact test cases using matters needing attention

Hot and cold impact testing-equipment' target='_blank'>test chamber is a kind of commonly used laboratory equipment, for testing raw material structure or polymer materials, in a flash of the extremely high temperature and cryogenic continuous natural environment to withstand natural environment experiment on the level of machinery and equipment. Has stable operation, high credibility, simple maintenance, wide application field, such as advantages, has been widely used in several industries. So in the use of hot and cold impact test cases need to pay attention to? To minimize the closed in three minutes and open hot and cold impact test cases of refrigerating units in order to avoid affect the function of the compressor. Hot and cold impact test chamber is forbidden to heat or testing explosive, flammable, flammable and high corrosive substances, otherwise will cause unnecessary damage. By specific practical operation of the personnel of cold and hot shock test chamber, so as to avoid unnecessary damage due to the actual operation is not standard. Hot and cold impact test in the test object's capacity does not influence personal studio cyclone balance and smooth, or it will affect the hot and cold impact test case characteristics and the real and effective. Vertical split inner loop flow wind frequency of arbitrary cross section, the area of the test item shall not exceed the total personal studio the 1/3 of the bearing cross-section. Be stationary test to the sample (s) in the middle, can't literally put a side, or it will cause hot and cold impact test box basket askew. Hot and cold impact test chamber environmental test to shut the door, shut before operation, or it will cause personal studio gas leak, the experiment of characteristic rules, before taking a cryogenic, personal studio to wipe, should be 60 ℃ dry for 1 hour. Experiments in the cryogenic tank beyond the conditions of above 55 ℃, can not open the refrigeration. When hot and cold impact test cases run, should decrease as far as possible on the tail gate, because was in a cryogenic, bitter door open end of the internal FengBing condition of the air conditioning evaporator and its position, especially in the lower the temperature, the situation is more serious, if must open, should minimize the time. When to run, after equipment completely stop can open closed apply testing. Hot and cold impact test box in the operation process, open the tail very poor may cause the following effects: (1) high temperature cyclone is very risk to break the box; (2) the tail door side still maintain high temperature cause burns; (3) high temperature gas is likely to open fire alarm system, caused by wrong operation; So unless it is absolutely necessary, don't need to open the tail in the operation process. Hot and cold impact test box in the high temperature experiment box when the temperature is very high. Just finished the experiment or test during the whole process, if you want to open the box, open close the door to be very careful, keep in mind, walking along the open position, in order to avoid high temperature burns. Despite the cold and hot shock test box machine has perfect countermeasures to prevent to get an electric shock, but still need to pay attention to, especially in automatic control system for home appliances, work conditions, avoid by all means touching part of household appliances. Lest produce or get an electric shock accident for motor ground injury accidents; So please terminate the equipment operation, close the switch power supply before maintenance. The above explanation is the hot and cold impact test cases of the use of the matters needing attention, the hope can help you, if you want to learn more about information about hot and cold impact test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
