電加熱恒溫箱有什么機械故障呢？出現了常見故障又應當如何開展檢修呢？對于這2個難題人們接下去逐一認識一下。

What is the mechanical failure of the electric heating thermostat? How to carry out the overhaul when there are common faults? For these two problems, people will go on to understand one by one.

1、電加熱恒溫箱工作中室溫不勻稱，出現這種情況，應查驗恒溫箱箱里物件是不是阻塞送風模式道通風口或是是進氣口，還是恒溫箱箱里物件過多。

1. The room temperature of the electric heating thermostat is not symmetrical. In this case, it should be checked whether the objects in the thermostat block the ventilation outlet of the air supply mode or the air inlet, or whether there are too many objects in the thermostat.

2、培養箱不加熱同時伴有報警聲，但培養箱循環風機正常工作，同時溫控示“———"，此故障為培養箱傳感器損壞，更換一下傳感器就可以了。

2. The incubator is not heated and accompanied by alarm sound, but the incubator circulating fan works normally, and the temperature control "-". This fault is the incubator sensor damage, just replace the sensor.

3、電熱培養箱打開電源開關出現跳閘現象，出現此類情況可直接考慮更換培養箱加熱管，另保險絲座損壞也會出現此現象，但極少見。

3. The switch of power supply in the electrothermal incubator trips, which can be directly considered to replace the incubator heating tube. In addition, the fuse holder damage will also occur, but it is rare.

4、恒溫箱接入開關電源后，開啟恒溫箱電源總開關無顯示信息，多見保險管融斷，拆換就能，若保險管完好無損，立即拆換電源總開關。

4. When the thermostat is connected to the switching power supply, the main switch of the power supply of the thermostat has no display information. Most of the fuses are broken, and the fuses can be removed. If the fuses are intact, the main switch of the power supply should be removed immediately.

5、電熱培養箱不加熱但溫控儀顯示正常，培養箱此故障多為加熱損壞，更換即可，在檢修培養箱該故障時應確保循環風機正常運行。如果培養箱循環風機不運轉也會引起不加熱現象，但培養箱箱內溫度會有5℃左右的溫升，打開箱門時會有少量焦糊味道，比較容易判斷是培養箱加熱管或者是循環風機故障。

5. The incubator is not heated, but the temperature controller shows normal. The incubator is usually damaged by heating. It can be replaced. When overhauling the incubator, the circulating fan should be ensured to run normally. If the circulating fan of the incubator does not work, it will also cause no heating phenomenon, but the temperature in the incubator will rise about 5 C. When the door of the incubator is opened, there will be a small amount of burnt taste. It is easier to judge whether the incubator heating pipe or the circulating fan is out of order.http://www.crxyq.cn/
