Is the bigger the vacuum level of a vacuum cleaner, the better?

Vacuum cleaners use a high vacuum created by a turbine pump to collect dust. The vacuum value indicates that the actual pressure of the system is lower than atmospheric pressure, which is often called negative pressure.wet dry stick vacuum Vacuum degree refers to how rarefied a gas is in a vacuum. Vacuum degree has also become an important indicator to measure the size of vacuum suction, but isn't the bigger the vacuum, the better? First, we know how a vacuum cleaner works.

A vacuum cleaner operates a vacuum pump at high speed to create a certain degree of vacuum. First,wet and dry vacuum cleaner for home the air in the vacuum cleaner's filter chamber will be removed. At this time, the atmospheric pressure inside the filter chamber will be lower than the external atmospheric pressure, so a pressure difference will occur and the air outside the chamber will be replenished to form a pressure balance. When air enters, it will also bring dust into the filter chamber of the vacuum cleaner. The vacuum is great. The thinner the air in the filter chamber and the greater the pressure difference, the easier it is to absorb dust. Therefore, the degree of vacuum reflects the suction power of the vacuum cleaner.

Of course, under a certain degree of influence, we teachers can think that the greater the vacuum degree of the vacuum cleaner, the greater the suction power, and the vacuuming effect will not be very good. However, with the introduction of information resource-saving economic society, the energy consumption of equipment has also become a very important indicator. The higher the vacuum degree, the greater the power required by the vacuum pump and the greater the energy consumption. Therefore, when selecting a vacuum cleaner, we must first calculate the teaching design method based on different working conditions data and select the appropriate model. Vacuum degree value to avoid excessive energy waste caused by the environment. The greater the vacuum, the greater the burden on the fan.

In fact, there is another important evaluation index for vacuum degree, which is to overcome the pressure loss of the vacuum pipe network. When the air flows inside the pipe due to the friction of the pipe wall and the change of the flow direction, resistance loss and local resistance loss will occur along the way. These pressure losses require vacuum to overcome. If the vacuum is too small and overcomes the resistance loss in the pipeline, a pressure difference will occur and the vacuum will become weaker, affecting the use effect.

Therefore, the choice of vacuum degree needs to be selected through specific calculations. Too large or too small will affect the use of the vacuum cleaner.
