How does the vacuum cleaner work

  • Date:2019-03-11
  • The vacuum cleaner motor is the heart of the vacuum cleaner. The main types of vacuum cleaner motors are: dry vacuum cleaner motor, wet and dry vacuum cleaner motor.The vacuum cleaner motor consists of two parts: the motor part and the fan part. Because the vacuum motor has a high rotational speed requirement, half of it is 20,000-30,000 rpm, so the motor mainly uses a series-excited motor, also called a series-excited motor. The working principle of the vacuum cleaner motor: The fan part of the vacuum cleaner motor mainly has two main components: the moving impeller and the fixed impeller. The moving impeller mainly generates wind. When the impeller is rotated at a high speed of 20000-30000 revolutions per minute.

    At the tuyere, a negative pressure is generated to form a vacuum, which in turn forms a suction force. The fixed impeller, also known as the wind guide wheel, is mainly used to make the air volume generated by the impeller become smoother and smoother, and the impeller air duct is better or worse, directly affecting the vacuum cleaner motor. Effect. Vacuum cleaner motors are not limited to applications that are used on vacuum cleaners, such as bubble baths, spray paints, stage artificial snowflakes, agricultural machinery, etc. that require suction.The series-excited motor is mainly composed of a stator, a rotor, a front and a rear cover (cover) and a heat-dissipating fan blade.

    The stator is composed of a stator core and a winding sleeved on the pole piece, and the function is to generate a field magnetic flux, a magnetic flux and Supporting the front and rear covers; the rotor is composed of a rotor core, a shaft, an armature winding and a commutator, and its function is to ensure and generate a continuous electromagnetic moment, and the work is carried out by the rotating shaft to convert the electric energy into mechanical energy; the front and rear covers support the armature The fixed shaft and the rotor are fixed and integrated into one body. The rotating shaft, the front and rear covers must have sufficient strength to prevent the armature from resonating with the cover, causing vibration and danger.

    Generally, there are rolling or sliding in the front and rear covers. Bearing.After understanding the basic structure of the series motor, it returns to the fan part of the vacuum cleaner motor. The fan part mainly has two main components: the moving impeller and the fixed impeller. The moving impeller mainly generates wind, and the impeller is 20,000-30000 rpm. When the high speed of the minute is rotated, a vacuum will be generated at the air inlet to form a vacuum, which will form a suction force. The fixed impeller, also known as the wind deflector, is mainly used to make the air volume generated by the impeller smoother and release. The quality of the road directly affects the efficiency of the vacuum cleaner motor.Vacuum cleaner motor applications: various household industrial dry vacuum cleaners, wet and dry vacuum cleaners, central vacuum cleaners, industrial vacuum cleaners and various types of sweepers. In fact, the vacuum cleaner motor is not limited to the application of vacuum cleaners, such as bubble bath, spray paint, stage artificial snow, agricultural machinery and other equipment that requires suction.
