  • Analysis of different noise generating mechanisms and its effect on noise level on high efficient vacuum cleaner suction unit [Elektronski vir]
    Biček, Andrej, 1982- ...
    Most manufactures of vacuum cleaners has adapted to regulation of Energy labelling of vacuum cleaners which started on EU market since September 2014. The new vacuum cleaners were designed and ... optimized to reduced input electric power at same or higher dust pick up values. Domel as leading European producer of vacuum cleaner suction units already today produce over 75% of units in range of up to 900 watts of input electric power. This indicates that most of vacuum cleaners are today present in top classes of Energy labels and they are already prepared for new stricter regulation which will become mandatory from September 2017. It is going to limit electric input power of appliances to max. 900 watts and new restrictions will additionally be set for sound power level as well. These indicators support consumers at their decision when purchasing a new vacuum cleaner. This paper presents analysis of different noise generating mechanisms and their effects on noise level of vacuum suction cleaner unit alone. Further are described effects of proper assembly into appliance with goal to get silent vacuum cleaner. Experiment presents rotor unbalance effect of centrifugal blower through sound and vibration results on VCU alone and on vacuum cleaner.
