一般在我们使用冷干机的过程中,如果冷干机不制冷怎么解决?不制冷就意味着无法正常工作,更不能去除水份,等于没有开机一样,这是什么原因造成的?杭州冷干机的小编整理了一下冷干机不制冷原因以及解决方法,一起来了解一下吧!
 
  这首先检查冷凝器的散热情况,一般风冷式冷凝器应经常清洗散热铝片。散热铝片起着重要的散热作用。
 
  还要检查冷媒是不是足够,看压力表情况
 
  压缩机故障(用手摸空气管路的外壁会感觉到没有温差或者是温差很小,打开箱板触摸压缩机的进出口,高压管会是温热的,低压管会是冰凉的,压缩机不运行,或高低压表是一样的读数)
 
  漏氟(如果高低压表都为零,检漏补漏就好。如果高压很高,低压很低,说明干燥过滤器堵。如果把氟利昂放光,看有无压力,若有压力,说明蒸发器泄露)
 
  是否有水排出
 
  进出空气是否有温差。

  回气管是否结露,压缩机上不允许结露。
 
 
 
 
 
  冷干机内部检查原因
 
  1检查机组是否存在漏氟的现象;
 
  2检查压缩机是否存在异常;
 
  3检查机组膨胀阀膨胀效果是否正常;
 
  4检查冷媒高压是否在正常值内;(12~18Bar。一般使用R22型号冷媒)
 
  5检查冷媒低压是否在正常值内;(3~5bar。)
 
  6检查冷干机进气温度是否偏高;(因为冷冻式干燥机的负荷时依据机器进气温度决定的,进气温度越高冷干机负荷越重)
 
  
 
 
  救急的办法
 
  1先把空压机储罐的下排水口稍微开一点 排水,检查冷媒看看压力多少?是不是比正常低
 
  2还有就是检查电路 是不是控制部分有问题;如果是水冷机请查看冷冻式干燥机的冷却水是否正常。
 
  3压缩机正常使用的温度大约在90度左右;调节旁通阀,如果没有用,那么建议更换压缩机。

In the process that we use cold dry machine commonly, if cold dry machine does not refrigerate how to solve? No refrigeration means that it cannot work properly, not to mention the removal of water, is equal to no boot, what is the cause of this? Hangzhou cold dry machine small make up the cold dry machine not refrigeration reasons and solutions, together to understand it!
 
 
 
This first check the cooling of the condenser, general air-cooled condenser should often clean cooling aluminum sheet. Heat dissipation aluminum sheet plays an important role in heat dissipation.
 
 
 
Also check whether the refrigerant is enough, according to the pressure gauge
 
 
 
Compressor failure (if you touch the outer wall of the air pipe, you will feel that there is no temperature difference or the temperature difference is very small. If you open the box and touch the inlet and outlet of the compressor, the high-pressure pipe will be warm and the low-pressure pipe will be cold, the compressor will not operate, or the high and low pressure meter will read the same)
 
 
 
Fluorine leakage (if the high and low pressure meters are zero, it is good to detect leakage. If the high pressure and low pressure are very low, the dry filter is blocked. If the freon is shining, see if there is any pressure. If there is pressure, the evaporator is leaking.
 
 
 
Whether there is water discharge
 
 
 
Whether there is temperature difference in the air.

Whether the return pipe condensation, condensation is not allowed on the compressor.
 
 
 
 
 
 
 
 
 
 
 
Check the internal reason of the cold dryer
 
 
 
1 check whether the unit has leakage of fluorine;
 
 
 
2. Check whether the compressor is abnormal;
 
 
 
Check whether the expansion effect of the expansion valve of the unit is normal;
 
 
 
4. Check whether the refrigerant high pressure is within the normal value; (12 ~ 18 bar. R22 type refrigerant is generally used)
 
 
 
5. Check whether the refrigerant low pressure is within the normal value; (3 ~ 5 bar.
 
 
 
6. Check whether the inlet air temperature of the cold dryer is on the high side; (because the load of the freeze dryer depends on the inlet temperature of the machine, the higher the inlet temperature, the heavier the load of the cold dryer)
 
 
 
7. See whether the refrigerant perfusion capacity of the cold dryer reaches the rated standard of the unit;
 
 
 
An emergency measure
 
 
 
1 first the air compressor storage tank under the outlet slightly open a little water, check the refrigerant to see how much pressure? Is it lower than normal
 
 
 
2 also is to check the circuit is not the control part of the problem; If it is a water cooler, please check whether the cooling water of the freeze dryer is normal.
 
 
 
3 the temperature of normal use of the compressor is about 90 degrees; Adjust bypass valve, if it does not work, then it is recommended to replace the compressor.
 
 
 
The above is hangzhou linuo small series of science and technology to everyone, how to solve the problem of cold dry machine refrigeration? , hope this article has the help to everybody, has the need cold dry machine can contact us!
