通风机是应用十分广泛的输送气体的机械。它把原动机的机械能转变为气体能量,这一过程必须经动力和传动系统才能完成。据统计,通风机耗电量约占全国用电量的10％左右。通风机动力和传动系统中的能量损失约占总输入能量的10～37％。因此,对风机进行节能无疑具有重要的意义。人们往往重视通风机本身如何提高效率,而对动力和传动系统的节能往往忽视。本文对通风机动力 Fan is a widely used gas conveying machinery. It translates the mechanical energy of the prime mover into gas energy, a process that must be completed by power and driveline. According to statistics, fan power consumption accounts for about 10% of the national electricity consumption. The energy loss in the fan power and transmission system accounts for about 10-37% of the total input energy. Therefore, the fan energy saving is undoubtedly of great significance. People tend to pay attention to how the fan itself improves efficiency, while energy and drivetrain energy savings are often overlooked. This article on the fan power
