怎樣來(lái)分辨換氣老化箱環(huán)境溫度是不是正常?通氣式老化試驗(yàn)箱的zui高溫度達(dá)到150 ℃、350℃和400℃。
在做實(shí)驗(yàn)時(shí)、因?yàn)橄淅餃囟鹊倪B續(xù)不斷上升，導(dǎo)致殼體表層也會(huì)有必須的發(fā)熱量、應(yīng)怎樣來(lái)分辨通氣老化試驗(yàn)箱環(huán)境溫度是不是正常，杭州綠博儀器有限公司請(qǐng)選擇下列方法開(kāi)展精確測(cè)量：
換氣老化箱操作溫度超過(guò)zui高操作溫度并平穩(wěn)2h后，用些溫檢測(cè)殼體表層(距門縫、電機(jī)孔、排出氣孔等周邊90毫米之外的地區(qū))溫度，其結(jié)果應(yīng)合乎給出規(guī)定:
1、zui高操作溫度不超出150℃的老化箱，環(huán)境溫度應(yīng)并不大室內(nèi)溫度加45℃。
2、操作溫度超出150℃的老化箱，環(huán)境溫度按下述方法測(cè)算決策：
3、T≤Tr+45+(Tm-150)/12(式中：T為老化箱環(huán)境溫度，℃;
4、換氣老化箱Tr為室內(nèi)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, ℃.)
