空氣壓縮機性能提昇精進方案
Study on Air Compressor Performance Tests and Improvements
摘要
空氣壓縮機在工業上佔有不可或缺的地位，幾乎各型工廠都需要設置空氣壓縮機，但在使用空壓機時，約有10%以上的電力消耗掉，在工廠中，壓縮空氣為一個昂貴的能源，因此增加空氣壓縮機效率將可得到明顯的節能。 本研究建立之實驗室為小型空壓機性能試驗實驗室，以風管及噴嘴進10HP空壓機之性能試驗，可獲得該空壓機之空氣流率Qs、容積效率ηv、絕熱總效率ηad、耗能比值(Qs/馬力數）。 由試驗結果可知在換用高流量之空氣濾心後，空氣壓縮機無論在空氣流率、容積效率、絕熱總效率、耗能比值的表現都有顯著提升，因此高流量型空氣濾網在使用時耗電量會比較少。另外在換用大型皮帶輪鼓所帶動之高速空壓機，因換用大型皮帶輪鼓使空壓機轉速提高也相對使電動馬達輸入功率昇高，將使絕熱總效率(ηad)與耗能比值(Qs/馬力數）降低。使得換用大型與原廠皮帶輪鼓均較耗電且相對使用成本提高，而中型皮帶輪鼓相對較佳，可節約2-3％能源耗用。

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.
