Understand the main performance parameters of screw air compressor

1. Unit volume flow The actual air volume flow at the standard exhaust position of the air compressor unit, converted to the full temperature, full pressure and component state of the standard suction position. Generally, the unit volume flow of the screw air compressor under specified working conditions should not be less than 95% of the nominal volume flow. 2. Unit power The total input power required for the air compressor unit to complete the compressed air output. Note that the total input power does not include the power used by the compressed air post-processing equipment integrated in the air compressor unit. 3. Unit specific power The ratio of the air compressor unit power to the unit volume flow under specified working conditions. 4. No-load power The unit power when the compressor head is in operation and the unit volume flow is zero. Generally, when the rated exhaust pressure is 0.7MPa, the ratio of no-load power to unit power does not exceed 35%; when it is 0.8MPa, the upper limit of no-load po
