[0002] Industrial vacuum cleaners use AC power and have high power. They are generally divided into two types: mobile and fixed. The working principle is to use a motor to drive a high-voltage extension to generate negative pressure in a limited volume, thereby generating suction. After the medium is sucked in, it is filtered through a filter bag or a filter barrel for secondary filtration. The ordinary type can only absorb dry medium with high water content, and the dry and wet dual-purpose type can absorb oil, water, etc. generated during the processing. After installing an exhaust pipe, it can be used to absorb smoke, gas, etc. generated during the production operation.
