冷熱沖擊試驗(yàn)機(jī)溫度不達(dá)標(biāo)的原因分析
1、察看溫度的變化,是溫度降的很慢,還是溫度到必然值后溫度有回升的趨勢(shì),前者就要檢查一下,做低溫試驗(yàn)前是否將工作室烘干,使工作室連結(jié)干燥后再將試驗(yàn)樣品放入工作室內(nèi)再做試驗(yàn),工作室內(nèi)的試驗(yàn)樣品是否放置的過多,使工作室內(nèi)的風(fēng)不能充實(shí)輪回,在解除上述原因后,就要考慮是否是制冷系統(tǒng)中的故障了,這樣就要請(qǐng)廠家的專業(yè)人員進(jìn)行檢修。
1, looking at the temperature changes, the temperature drop is very slow, or temperature to a certain value after the temperature has increased, the former should check whether low temperature drying, the studio before the test, the studio link drying after the test sample into the studio to do the test, the test sample is placed in the studio too much, so that the windcan't in the studio full cycle, in the lifting of the above reasons, it is necessary to consider whether it is the fault in the refrigeration system, so as to invite manufacturers of professional personnel for maintenance.
2、設(shè)備的利用環(huán)境不好所致,設(shè)備放置的環(huán)境溫度,放置的位置(箱體后與墻的距離)要滿足要求(在設(shè)備操作利用說明中都有劃定)。
By 2, due to poor equipment, equipment placed in the environmental temperature, the location (distance and the wall of the box body) to meet the requirements (are delineated in the equipment operation using description).
