Vacuum Cleaner Principle
Apr 20, 2018

The main components of a modern vacuum cleaner are vacuum pumps, dust collection bags, hoses and various nozzles of different shapes. The inside of the machine has an electric exhaust fan. After being energized, it operates at a high speed, creating a momentary vacuum inside the vacuum cleaner. The internal pressure is much lower than the outside. The air pressure, under the action of this pressure difference, dust and dirt enters the vacuum cleaner barrel with the air flow, and then passes through the dust bag filter, the dust stays in the dust bag, and the purified air is evacuated into the room through the motor. To cool the motor and purify the air.
