During the process of using the air compressor, the machine will stop after the failure of the young machine, and the machine crew must be able to test or repair the air machine under the premise of air pressure. And the main compressed air discharge, the need for a kind of post-treatment equipment — cold drying machine or suction drying machine. The complete name of refrigeration drying machine and suction drying machine, air compression machine is essential post-treatment equipment. Is it possible to have a cold drying machine or a drying machine? Do the two have their own strengths or weaknesses? Take care of the landlord.
Differentiate between cold drying machine and drying machine
1 Working principle
Refrigerating machine is based on the principle of cooling and dehumidification, future self-sufficient pressure air supply refrigerant heat exchange, cooling to a constant dew point temperature, simultaneous condensation and precipitation of a large amount of liquid water, recirculating gas liquid separator after separation, automatic discharge machine In addition, the effect of water removal and drying; the drying mechanism is based on the principle of changing pressure absorption, so that the drying agent comes into contact with the drying agent under a certain pressure, and the drying agent is naturally absorbed by the compressed air. After drying, air inflow and down work, reach deep drying.
2 Water removal effect
Refrigerating machine receiver own principle control, low temperature machine produced ice, due to machine dew point temperature normally maintained at 2~10℃; Deep drying, exit dew point temperature can reach -20°C or less.
3 capacity consumption
Refrigerant through the refrigerant pressure arrives at the cooling purpose, so the demand is very high power efficiency;
4 air consumption
Water is removed from the temperature through the cold drying machine, the water produced during the process is automatically discharged through the drainer, and the amount of air is exhausted; 12-15% left and right regeneration gas wear.
5 capacity consumption
Refrigeration equipment has refrigerant, air, electricity, three major systems, compositional system elements have been recovered, the rate of output failure has increased; Due to this, under normal circumstances, the failure rate of the drying machine is high due to the drying machine
What are the refrigeration advantages?
advantages
1. Compression-free air consumption
Most of the pressure and air dew point requirements are not very high, the air absorption and drying phase ratio, the use of cold drying equipment to save energy
2. Everyday life simple
No need to polish, just use the automatic cleaning drainer as soon as possible
3. Low traffic noise
Compressed in the air, the general noise of the cold air machine
4. Very little solid matter content in the gas discharged from refrigerators and dryers
Compressed in the air, the general noise of the cold air machine
disadvantages
100% effective air supply for cooling and drying equipment, but due to the control principle of receiving work, the minimum supply air dew point can reach 3°C left and right; The air temperature is also very high, and the ambient temperature has a large impact.
What are the advantages of the drying machine?
advantages
1.Compressed air dew point can reach -70℃
2. Unaffected by ambient temperature
3. Passive effect and passthrough
flaw
1. Compressive air consumption, non-cold air consumption and easy consumption power
2. Demand periodical addition, renewal absorbent;
3. Sucking machine with sucking tower wholesale pressure noise,
65 minutes
The above is the difference between the cold drying machine and the drying machine, and the two have their own advantages.
