空压机节电 Energy saving of air compressor 变频节能思路 Energy saving ideas of frequency conversion 1、集中控制方式 1. Centralized control mode 多台空压机集中控制。根据用气量变换情况，自动控制运行台数。 Multiple air compressor centralized control. According to the volume of gas consumption, automatic control of the number of operating stations. (1)当用气减少到一定量时，通过减少加载时间，来减少产气量。 (1) when gas consumption is reduced to a certain amount, gas production can be reduced by reducing loading time. (2)若用气量进一步减少，性能好的空气压缩机自动停机。 (2) if the volume of gas is further reduced, the air compressor with good performance will stop automatically. 2、变频调速方式 2. Variable frequency speed regulation 取变频调速方式，降低电动机轴功率输出。改造之前，空压机达到设定压力时，即会自动卸荷；改造之后，空压机并不卸荷，而是降低转速减少产气量，维持气网压力。这里有两个地方可以节能： 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)减少从卸荷到加载，这一过程的耗电。 (1) reduce the power consumption from unloading to loading. (2)电机运转降低至工频以下，可减少电机轴输出功率。 (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、软启动节能 3, soft start energy saving 使用变频节能装置，利用变频器的软启动功能，启动电流从零开始，不超过额定电流，减轻电网冲击、供电容量要求，延长设备、阀门的寿命。 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、功率因数补偿 4, power factor compensation 电机无功功率，增加线损和设备发热，功率因数下降使有功功率降低，设备使用效率低下浪费严重。使用变频调速装置后，因变频器内部滤波电容作用，减少无功损耗，增加了电网有功功率。 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. 空压机节能 Energy saving of air compressor 余热回收节能思路 Energy saving ideas of waste heat recovery 用户都知道，空压机运行温度很高，特别是夏季。长期运行高温状态，零部件、润滑油更换平凡，因此空压机寿命大大缩短。而空压机余热回收，能够解决这个问题。 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. 空压机余热回收原理 The principle of waste heat recovery for air compressor 回收空压机油、气全部热量，冷水快速直热转换热水，经保温管至热水存储系统，在泵送至工厂用热水点。保持空压机长时间运行温度，提高空压机供气质量，减少空压机零件更换周期，停用原有冷却系统。 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.
