Question:

Air compressor or small pump is how to determine how much spray guns can be equipped with the wind?

Pneumatic tools are used to air pressure, and piston type compressors can generally provide the rated exhaust pressure between 7 kg to 8 kg, the amount of exhaust per minute of knowledge change, then this is how to calculate?

Answer:

It's better to buy an air compressor with a variable frequency, but provide the amount of air that doesn't use the spray gun and the wind, and how many times you use it! Do not give you a larger air compressor, you say you do not use so much, to provide a small, you certainly do not say enough.
1, determine your gas consumption (pneumatic tools can be used to obtain), gas pressure. 8 kilograms is enough2 and then select the right air compressor according to the amount of air you have calculated. Generally more than 20% of the rated gas (consider leakage, etc., of course, the choice is just right, you use those gas equipment will not use it at the same time.)3, the pressure should be slightly larger choice, because the gas pressure loss in accordance with the transmission distance4, of course, willing to spend money, with much better frequency conversion screw machine point, it can be based on your actual consumption (to change the frequency to change the motor speed, power), better scalability (if you want to have more gas, will no longer increase equipment... At most, the frequency converter is used as the power frequency machine, and the electricity saved at that time saved the converter's cost. There are some tips for choosing the main road. When you buy the equipment, you can ask the manufacturer to help you design itPiston compressor is not what you said, the rated pressure is only 7---8 kg, and its pressure range is wider than the screw machine, 200 kilograms also have!!! Screw machine, then the first level of compression will be 13-15 kilograms, two compressed 30 kg.....If the screw machine, the wearing parts are less than the piston machine.... Like the piston, often replace the piston ring, into the exhaust valve, etc., and these have special maintenance personnel to engage in trouble
Depending on the volume of the spray gun you use
