On the other hand, it will not take long for a tool to do at 0.6MPa as a compressor generates more power. You should decide which helps you save cost, based on your various applications. The table 2 gives you an idea of coefficient of operation. The value to operate a number of tools simultaneously is smaller as there are an increasing number of tools in operation. The air consumption rate refers to the value in which a tool is used continuously for 1 minute. It is recommended, as shown in the table 3, that you should make the consumption energy value smaller than the actual value when you operate tools in the above-mentioned discontinuous operation and that you should make the consumption energy value larger than the actual value when you operate tools in the above-mentioned continuous condition. ② Discontinuous operation: 0.5 Energy Needed for CompressorQ≧6.5 kW × (V×n + V×n + V×n ・・・) × K × S × αQ : Energy needed for compressor (kW)V : Air consumption per tool (m3/min (normal cubic meter per Note: Value for tools except Screwdriver: 0.6MPa at gauge Value for Screwdriver: 0.4MPa at gauge.CompressorTheoretical Consumption Energy of CompressorTable 1You can refer to the table 1 to find the theoretical consumption energy of compressor, which is created through the adiabatic compression, to compress 1m3/min (normal cubic meter per minute) of free air to the various pressure levels. It is highly recommended that you should make the consumption energy value greater than the actual value by taking into consideration the machine efficiency including friction loss caused by compressor.
