An oil free scroll air compressor
device has many parameters and different parameter units are not necessarily the same. We have summarized several parameters about power for your reference, and hope to help everyone.
First, the work
Mechanical work can be defined as the product of the force acting on the object and the distance moved in the direction of the force. Like heat, work is an energy that can be transferred from one object to another. The difference is that force replaces temperature.
Second, the power
Power is the work done in a unit of time. It is the physical quantity that calculates the speed of work. Its international unit is Watt: 1W=1J/s.
Third, the shaft power
The drive is transmitted to the compressor shaft to meet the actual power of the oil-free air compressor design load capacity.
Fourth, the power factor
In the AC circuit, the cosine of the phase difference (Φ) between voltage and current is called the power factor and is represented by the symbol cosΦ. In terms of value, the power factor is the ratio of active power to apparent power, ie cosΦ=P/S.
Five, the specific power
The oil-free scroll air compressor consumes the power consumed by the unit gas volume per unit time to complete the compression process. Usually expressed in Kw/M3/Min. The lower the specific power at the same exhaust pressure, the less power the oil-free air compressor consumes, so it is an important indicator for evaluating the performance of oil-free compressors.
