空壓機節電 Energy saving of air compressor 變頻節能思路 Energy saving ideas of frequency conversion 1、集中控制方式 1. Centralized control mode 多臺空壓機集中控制。根據用氣量變換情況，自動控制運行臺數。 Multiple air compressor centralized control. According to the volume of gas consumption, automatic control of the number of operating stations. (1)當用氣減少到一定量時，通過減少加載時間，來減少產氣量。 (1) when gas consumption is reduced to a certain amount, gas production can be reduced by reducing loading time. (2)若用氣量進一步減少，性能好的空氣壓縮機自動停機。 (2) if the volume of gas is further reduced, the air compressor with good performance will stop automatically. 2、變頻調速方式 2. Variable frequency speed regulation 取變頻調速方式，降低電動機軸功率輸出。改造之前，空壓機達到設定壓力時，即會自動卸荷；改造之后，空壓機并不卸荷，而是降低轉速減少產氣量，維持氣網壓力。這里有兩個地方可以節能： The frequency conversion speed regulation mode is adopted to reduce the shaft power output of the motor. Before the retrofit, the air compressor will automatically discharge when the pressure is set. After the transformation, the air compressor does not discharge, but reduces the speed to reduce the gas production and maintains the minimum pressure of the gas network. There are two places to save energy: (1)減少從卸荷到加載，這一過程的耗電。 (1) reduce the power consumption from unloading to loading. (2)電機運轉降低至工頻以下，可減少電機軸輸出功率。 (2) the motor output can be reduced to below the power frequency, so that the output power of the motor shaft can be reduced. 3、軟啟動節能 3, soft start energy saving 使用變頻節能裝置，利用變頻器的軟啟動功能，啟動電流從零開始，不超過額定電流，減輕電網沖擊、供電容量要求，延長設備、閥門的壽命。 Using the frequency conversion energy saving device, using the soft start function of the frequency converter, the starting current starts from zero, the maximum does not exceed the rated current, reducing the power grid Impact and power supply capacity requirements, and prolonging the life of the equipment and valve. 4、功率因數補償 4, power factor compensation 電機無功功率，增加線損和設備發熱，功率因數下降使有功功率降低，設備使用效率低下浪費嚴重。使用變頻調速裝置后，因變頻器內部濾波電容作用，減少無功損耗，增加了電網有功功率。 The reactive power of the motor increases the line loss and the heating of the equipment, reduces the power factor and reduces the active power, and the equipment is inefficient and wasteful. After using the frequency conversion speed regulating device, the reactive power loss is reduced due to the internal filter capacitor of the inverter, and the active power of the power network is increased. 空壓機節能 Energy saving of air compressor 余熱回收節能思路 Energy saving ideas of waste heat recovery 用戶都知道，空壓機運行溫度很高，特別是夏季。長期運行高溫狀態，零部件、潤滑油更換平凡，因此空壓機壽命大大縮短。而空壓機余熱回收，能夠解決這個問題。 As we all know, the air compressor runs very high, especially in summer. In the long run of high temperature condition, parts and lubricating oils are replaced by ordinary ones, so the life of air compressors is greatly shortened. The waste heat recovery of air compressor can solve this problem. 空壓機余熱回收原理 The principle of waste heat recovery for air compressor 回收空壓機油、氣全部熱量，冷水快速直熱轉換熱水，經保溫管至熱水存儲系統，在泵送至工廠用熱水點。保持空壓機長時間運行溫度，提高空壓機供氣質量，減少空壓機零件更換周期，停用原有冷卻系統。 Recover all the heat from air compressor oil and gas. The cold water is directly and directly converted to hot water, and then passes through the insulation pipe to the hot water storage system, and the hot water points are pumped to the factory. Keep the air compressor running for a long time, improve the air supply quality of the compressor, reduce the replacement period of the parts of the air compressor, and stop the original cooling system.
