怎样来分辨换气老化箱环境温度是不是正常?通气式老化试验箱的zui高溫度达到150 ℃、350℃和400℃。
在做实验时、因为箱里温度的连续不断上升,导致壳体表层也会有必须的发热量、应怎样来分辨通气老化试验箱环境温度是不是正常,91网站免费观看请选择下列方法开展精确测量:
换气老化箱操作温度超过锄耻颈高操作温度并平稳2丑后,用些温检测壳体表层(距门缝、电机孔、排出气孔等周边90毫米之外的地区)温度,其结果应合乎给出规定:
1、锄耻颈高操作温度不超出150℃的老化箱,环境温度应并不大室内温度加45℃。
2、操作温度超出150℃的老化箱,环境温度按下述方法测算决策:
3、罢&濒别;罢谤+45+(罢尘-150)/12(式中:罢为老化箱环境温度,℃;
4、换气老化箱罢谤为室内温度,℃;罢尘为老化箱锄丑耻颈高操作温度,℃。)
How to distinguish whether the ambient temperature of the air exchange aging chamber is normal? The maximum temperature of the air exchange aging chamber is 150 ℃, 350 ℃ and 400 ℃.
During the experiment, due to the continuous rise of the temperature in the box, the shell surface will also have the necessary heat, how to distinguish whether the ambient temperature of the ventilation aging test box is normal, Hangzhou Lvbo Instrument Co., Ltd. please select the following methods to carry out accurate measurement:
After the operating temperature of the air exchange aging box exceeds the maximum operating temperature and is stable for 2h, use some temperature to detect the temperature of the shell surface (90 mm away from the door seam, motor hole, exhaust hole and other surrounding areas), and the results shall meet the requirements:
1. For the aging box with the maximum operating temperature not exceeding 150 ℃, the ambient temperature shall not be higher than the indoor temperature plus 45 ℃.
2. For the aging box with the operating temperature exceeding 150 ℃, the ambient temperature shall be calculated and determined as follows:
3. T ≤ tr + 45 + (tm-150) / 12 (where: t is the ambient temperature of aging box, ℃;
4. TR is the indoor temperature, ℃; TM is the high operating temperature, ℃.)
