What is the principle of wet and dry vacuum cleaner?

In daily life, vacuum cleaner is commonly used, but its principle may not be understood. What is the principle of wet and dry vacuum cleaner? PChouse, let's take a look.

Wet and dry vacuum cleaners, also known as vacuum cleaners, as the name implies, have both functions of dust absorption and water absorption. Ordinary vacuum cleaners can only absorb dry media with less water content, while wet and dry industrial vacuum cleaners can absorb oil and water produced during processing.

The working principle of wet and dry vacuum cleaner is different from that of ordinary vacuum cleaner in that there is an extra centrifugal chamber. When dust, air and water are sucked into the centrifugal chamber, the heavier water rotates at high speed, and then it is thrown to the inner wall of the centrifugal chamber and flows into the water collecting bucket below. Lighter dust and air enter the filter bag to filter the dust after passing through the centrifugal chamber. Industrial vacuum cleaners mainly separate solids from air through filter media. Common industrial vacuum cleaners in the market generally have single filtration or double filtration. For example, the wet and dry vacuum cleaner is a filter element with a single filter material, and the dry vacuum cleaner is a dual filter system with a filter element and a filter bag. The general filtration accuracy of the filter element is about 65,438+00 microns.
