Terms and definitions of marine air compressor
Marine Air Compressor is an air compression equipment used on ships, whose main function is to compress air to a higher pressure for starting the main and auxiliary engines.
Overview
1. Rated condition: the working condition of air compressor jointly determined by the rated speed and the rated discharge pressure.
2. Volume flow: the air volume measured within unit time at the air outlet of air compressor operating under the rated condition and converted under the temperature and pressure of air aspirated before the first-stage air inlet.
3. Nominal volume flow: the air volume converted from the volume flow under the standard inlet condition and nominal speed.
4. Standard inlet condition: the condition of the aspirated air at the standard inlet position of the compressor where the inlet air temperature is 20°C, the pressure is the standard atmospheric pressure (0.101 MPa), the relative humidity is 0 and the cooling water inlet temperature is 15°C.
5. Nominal speed: The nominal speed is rounded from the rated speed for designing and comparing the performance of air compressors.
