按工作原理,风机可分为叶片式风机及容积式风机。国内叶片式风机数量最大,容积式风机由于效率低,叶轮寿命短,现已逐步淘汰。目前全国风机总量约700万台,装机容量近4000万千瓦,平均运行效率为50%,比规定的70%低得多,因此有较大的节能潜力。一、风机的节能改造风机节能的常用手段是合理选型并采用国家推荐的节能产品;使用节能效果好的调节方法;尽量避免串并联运行可
According to the working principle, the fan can be divided into vane fan and volumetric fan. The largest number of domestic blade fans, positive displacement fan due to low efficiency, short life impeller, has now been phased out. At present, the total number of wind turbines in the country is about 7 million sets, with an installed capacity of nearly 40 million kilowatts and an average operating efficiency of 50%, which is much lower than the prescribed 70%. Therefore, there is a great potential for energy saving. First, the energy-saving fan Fan common means of energy-saving is a reasonable selection and use of energy-saving products recommended by the country; the use of energy-saving adjustment method is good; try to avoid series parallel operation
