高低温冲击试验箱适用于航空、航天、军工、 电子、电工产品等模拟试品在大气温度急剧变化 条件下的适应性试验及对电子元器件的安全可靠 性试验和产品筛选。试验箱分为两箱式动态冲击和三箱式静态冲击,既可做高低温冲击试验,也可做单 独高温或低温试验。
The high and low temperature impact test chamber is suitable for the adaptability test of simulated test objects such as aviation, aerospace, military, electronic and electrical products under the condition of rapid change of atmospheric temperature, as well as the safety and reliability test and product screening of electronic components. The test chamber is divided into two-chamber dynamic impact and three-chamber static impact, which can be used for high and low temperature impact test, as well as separate high or low temperature test.
►两箱式:
Two boxes
分为上下、水平两种结构,采用气动机械装置进行转换,转换时间短,结构紧凑,体积小。
It is divided into two structures, up anddown,using pneumatic machinery for conversion,shortconversion time, compact structure andsmall volume.
►三箱式:
Three box type
通过气动系统控制的风门自动切换来实现温度转换,主要用于被测试样品在试验过程中必须静止不动以保证试品不受任何机械冲击。Thetemperature conversion is realized by theautomatic switching of the dampers controlledby the pneumatic system, which is mainly usedfor the tested sample, which must be stationaryduring the test process to ensure that the test product is free from any mechanical impact
众所周知,恒温恒湿试验箱因其性能优良、售后率低的特性,得到用户的广泛赞赏。在一般情况下,质量好的恒温恒湿试验箱因生产成本高,价格比劣质恒温恒湿试验箱要高30%左右。有些采用国内生产低价品牌压缩机、电器件制作的恒温恒湿试验箱,测试精准度和适应范围远远低于多家有关标准规定,使用很不安全。在选订恒温恒湿试验箱时应注意以下事项的鉴别:
2024-03-15结合多年的工作经验,笔者认为高低温试验箱对环境变化的检测效果会越来越好,每一个环境因素都可以被细微捕捉到。因此,无论是《高温试验箱技术条件》、低温试验箱的技术条件,或者湿热试验箱的技术条件、盐雾试验箱的技术条件,这些规定的检验规范,都会认为高低温试验箱的检测设备型号不同,从而产生“结论”的变化。
