Energy saving analysis of two-stage compression permanent magnet inverter compressor:
After the air is compressed in the first stage, it is cooled by enhanced oil injection to reduce the temperature of the second stage suction, and the air undergoes isostatic compression to reduce the compression work.
Two-stage compression uses equal pressure ratio to set the inter-stage pressure, so the compression ratio of each stage is much lower than the single-stage compression ratio, the return leakage between the rotors is greatly reduced, and the volumetric efficiency and adiabatic efficiency are greatly improved. Correspondingly, the compressed gas production is increased.
The main engine adopts a large rotor, low speed design, and contains two independent compression units.
Combining the first-stage compression rotor and the second-stage compression rotor in a casing, the compression ratio of each stage is small, the leakage is smaller, and the volumetric efficiency is high.
Under the same power, the load is borne by the two heads, the bearing force is small, and the life is longer.
Compared with single-stage compression, energy saving is 15%.
Oil lubrication system: Separate the compression cavity and the bearing oil supply independently. The compression cavity adopts ordinary clean lubricating oil, and the bearing part adopts high clean lubricating oil to ensure the high reliability of the bearing.
Fully enclosed air-cooled air compressor special motor: IP55 protection grade, F grade insulation, B grade temperature rise, effectively prevent dust and moisture from entering the motor. Using SKF bearings to ensure long-term continuous and trouble-free operation.
Cooler: A large margin aluminum fin cooler is used to ensure a good cooling effect when the ambient temperature is 45°C.
Inverter: Choose the inverter of the best brand in the industry, which is stable, intelligent and efficient. It can carry out stepless speed regulation, through the PID regulator inside the inverter, it can realize smooth start and adapt to any working conditions with large fluctuations in air volume.
Two-stage compression process
The natural air enters the first stage compression through the air filter, and is mixed with a small amount of lubricating oil in the compression chamber, and at the same time, the mixed gas is compressed to the interstage pressure. The compressed gas enters the cooling channel and comes into contact with a large amount of oil mist, thereby greatly reducing the temperature. The cooled compressed gas enters the secondary rotor, undergoes secondary compression, and is compressed to exhaust pressure. The compressor is discharged through the exhaust flange to complete the entire compression process.
Two-stage compression energy saving case
The single-stage compression air compressor 250KW model runs about 200 yuan per hour at full load, and the annual electricity cost is about 1.6 million yuan for 8000 hours.
Compared with a single-stage compressor, the use of a two-stage compressor can reduce power consumption by more than 10%. Using two-stage compression will save 160,000 yuan per year.
