Yixing Air Compressor | Cold Dryer Failure Cause Analysis
What is the reason why the exhaust temperature of a cold dryer is too high
?
The inlet temperature of compressed air is too high or the flow rate is too large
The working conditions of the refrigeration system change
causing the refrigerant evaporation temperature to rise
causing the compressed air to not be sufficiently cooled in the evaporator
The heat dissipation from the outer wall of the precooler pipe is too large
What is the reason for the low exhaust temperature of the secondary cooling dryer
?
The heat exchange area of the precooler is insufficient but the evaporator has more cooling capacity
The compressed air inlet temperature is low or the flow rate is too small< br/> The working conditions of the refrigeration system have changed
The refrigerant evaporation pressure is lower than the normal value
What is the impact of the third refrigerant filling amount on the refrigeration dryer
?
The refrigerant filling is too much Less
The following phenomena will occur in the cold dryer
Evaporation pressure
The cooling pressure is lower than normal operation
But the air dew point cannot be lowered.
The compressor casing is hot
Too much refrigerant is poured
The chance of cooling and drying appears
As the refrigerant liquid accumulates in the refrigerator
The cooling area is reduced
/>Resulting in an increase in refrigeration pressure
In severe cases, high pressure tripping
Increased load on the refrigeration compressor
Difficulty in starting
The refrigerant is not fully vaporized in the evaporator
Let wet steam enter the compressor
Yes
Liquid compression
Danger
Due to the increase in cooling pressure
The cooling capacity of the compressor will be reduced
The air dew point will rise< br/> Changzhou Longli Machinery Co., Ltd. is a professional company engaged in the design, installation, repair and maintenance of air compression systems.
