如何來判斷換氣老化箱表面溫度是否正常

新聞中心

怎樣來分辨換氣老化箱環境溫度是不是正常?通氣式老化試驗箱的zui高溫度達到150 ℃、350℃和400℃。

 

  在做實驗時、因為箱里溫度的連續不斷上升,導致殼體表層也會有必須的發熱量、應怎樣來分辨通氣老化試驗箱環境溫度是不是正常,杭州綠博儀器有限公司請選擇下列方法開展精確測量:

 

  換氣老化箱操作溫度超過zui高操作溫度并平穩2h后,用些溫檢測殼體表層(距門縫、電機孔、排出氣孔等周邊90毫米之外的地區)溫度,其結果應合乎給出規定:

 

  1、zui高操作溫度不超出150℃的老化箱,環境溫度應并不大室內溫度加45℃。

 

  2、操作溫度超出150℃的老化箱,環境溫度按下述方法測算決策:

 

  3、T≤Tr+45+(Tm-150)/12(式中:T為老化箱環境溫度,℃;

 

  4、換氣老化箱Tr為室內溫度,℃;Tm為老化箱zhui高操作溫度,℃。)

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, ℃.)
