Comparison of water-cooled air compressor and air-cooled
According to the cooling method, Dream air compressors can be divided into air-cooled air compressors and water-cooled air compressors, because their cooling methods are different, and their advantages are also different.
Air compressor cooling method
1. There is no obvious difference between air-cooled air compressor and water-cooled in machine operating parameters, and both are suitable for long-term continuous operation.
2. The traditional concept has the situation that the cooling effect of water cooling is better than that of air cooling. There are two reasons for this:
(1) Only a few international princes with complete technology and advanced craftsmanship can adopt air-cooling methods on large-displacement air compressors.
The company can do it, so many manufacturers who do not have this ability have long instilled the concept that water cooling is better than air cooling in customers.
Form thinking inertia.
(2) Ignore the long-term requirements of water-cooling methods for circulating water quality.
3. Advantages of air-cooled air compressor:
(1) Early-stage equipment investment and maintenance of the non-water cooling circulation system and the long-term dependence on the circulation system and water quality.
(2) There is no need to clean and maintain the water cooler of the air compressor regularly, which reduces the risk of shutdown due to maintenance.
(3) Reduced initial investment and equipment operation costs.
4. Matters needing attention when adopting air-cooling method: air-cooling is dependent on air.
The intake and exhaust air of the machine is exported outside the machine room, which can avoid the over-temperature shutdown caused by the circulation of cooling air in the machine room in high temperature days.
Comparison table of water-cooled and air-cooled air compressors:
l Air-cooled air compressor
Cooling medium Air-cooled,
110kw Air compressor
cooling air volume 496m3/min
l 280kw water-cooled air compressor Air compressor, cooling water volume 40T/hr, cooling water pressure>0.3Mpa. Cooling water pipe interface: DN65
Cooling effect
Compressed air outlet temperature: the ambient temperature is the ambient temperature +15°C, but air cooling has a greater impact on the environment. So the air compressor station
The room should be well ventilated.
Cost comparison
1 The purchase cost of the air compressor is the same,
2. Installation cost, air-cooling needs to be equipped with a wind deflector, this can be used as a wind deflector when installing the air compressor, and the installation cost is low.
3. The amount of water cooling water needs to be installed with a cooling tower. 4 sets of 110 watt air compressors need a cooling tower of 40m3/hr. The price of this single unit is almost more than 30,000.
Post-maintenance cost
l lAir-cooled air compressor, the later cooling system basically does not need maintenance
l lWater-cooled air compressors, because our domestic water can't be marked with soft water, the pipeline will become fouled after a period of use, and it will need to be cleaned with syrup, which is very troublesome.
