电加热恒温箱有什么机械故障呢?出現了常见故障又应当如何开展检修呢?对于这2个难题人们接下去逐一认识一下。

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、电加热恒温箱工作中室温不匀称,出現这种情况,应查验恒温箱箱里物件是不是阻塞送风模式道通风口或是是进气口,還是恒温箱箱里物件过多。

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、培养箱不加热同时伴有报警声,但培养箱循环风机正常工作,同时温控示“———",此故障为培养箱传感器损坏,更换一下传感器就可以了。

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、电热培养箱打开电源开关出现跳闸现象,出现此类情况可直接考虑更换培养箱加热管,另保险丝座损坏也会出现此现象,但极少见。

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、恒温箱接入开关电源后,开启恒温箱电源总开关无显示信息,多见保险管融断,拆换就能,若保险管完好无损,立即拆换电源总开关。

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、电热培养箱不加热但温控仪显示正常,培养箱此故障多为加热损坏,更换即可,在检修培养箱该故障时应确保循环风机正常运行。如果培养箱循环风机不运转也会引起不加热现象,但培养箱箱内温度会有5℃左右的温升,打开箱门时会有少量焦糊味道,比较容易判断是培养箱加热管或者是循环风机故障。

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./
