Focused on compressed air system design, air treatment, piping configuration, equipment maintenance, and common industrial air issues, with practical guidance based on pressure, flow, dew point, air quality, and operating conditions for equipment selection, system optimization, and routine operation and maintenance.
It is suggested to allocate 110 cubic meters per minute, plus a margin of about 20% to deal with production fluctuations and pipeline leakage. That is to say, with a water-lubricated oil-free air compressor of about 130 cubic meters per minute, plus a cold dryer or a suction dryer for post-treatment, it is basically enough.
If it is a small and medium-sized casting enterprise, the annual gas consumption is about tens of thousands to hundreds of thousands of cubic meters. Large-scale iron and steel casting joint enterprises, nitrogen alone may be tens of millions of cubic meters.
General purpose cold dryer is enough, high requirements on the suction dryer, the optimal solution is cold dryer and suction dryer in series, water lubrication oil-free air compressor with this combination of water treatment problem is very suitable.
It takes tens to hundreds of hours for the oil injection machine pipeline to clear the oil, and regular maintenance is required in the follow-up. There is no oil in the water-lubricated oil-free pipeline. It is only necessary to solve the water problem.
Turn off the air compressor first, wait for the pressure in the pipeline to slowly drop, and then turn off the cold dryer. When starting up, turn on the cold dryer first to preheat it stably, and then turn on the air compressor. In this way, the cold dryer always works in a state of airflow, which is not easy to cause problems, and the air pipe can be kept clean.
Generally, it is a combination of gas-water separator and dryer. Water lubricated oil-free air compressor is recommended to be equipped with at least one dryer because it has a lot of water, so there will be no water in the air pipe.
Nitrogen in the semiconductor factory is bodyguards, cleaners, porters and air conditioners, while the water-lubricated oil-free screw air compressor is the source that provides clean raw materials for the nitrogen machine. The source is not clean, and the back is completely useless.
Dry oil-free or water-lubricated oil-free, the answer is that there is no need to add oil. But the difference between the two is that dry oil-free is completely carried by mechanical precision, and water-lubricated oil-free is helped by water. The latter has more advantages in stability and maintenance convenience in long-term use.
The core of the air source in the bottle blowing factory is the combination of water lubricated oil-free screw air compressor plus drying and multi-stage filtration. Because the bottle is in direct contact with the food, the air quality cannot tolerate the slightest sloppiness.
If there is a large number of air blowing and cooling processes in your processing, the air consumption will be obviously too large. It is suggested to directly match the air volume according to 8 cubic meters per minute or even higher. It is better to match the air pressure instead of being too small, so as not to report to the police and stop the machine when working, which will affect the production.
