| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 98 === Air compressor was an important machine in industrial, that each factory must establish it. Many air compressors may be running at efficiencies as low as 10 percent. Compressed air is one of the most expensive sources of energy in a plant. Improving air compressors efficiency can yield significant savings to your facility.
The air compressor performances test laboratory was established. The 10HP air compressors were tested. The air flow rate, volume efficiency, adiabatic thermal efficiency, and energy consumption ratio (Qs/ horsepower counts) were compared under various exhaust pressures.
By the experimental results showed that the air flow rate, volume efficiency, adiabatic thermal efficiency, energy consumption ratio were improved apparently by replacing high capacity air filter and the power consumption is also reduced. When the high-speed air compressor was instead by large-diameter pulley, then the motor input power raised and the adiabatic thermal efficiency and energy consumption ratio reduces. The medium-sized pulley is relatively good because they could achieve 2-3% of the energy economic.
