I. High-pressure or medium-pressure vacuum fans
Some production workshops and processing plants will produce more or less sundries and impurities during the production process. Metal scrap particles, etc., working in this working environment for a long time is not good for human health, so a vacuum fan is used to remove these dust particles.
Common vacuum fans generally include high-pressure vacuum fans and medium-pressure vacuum fans. When choosing, it is not necessarily good high pressure or medium pressure, because the pressure and energy consumption of the vacuum fan , noise, vibration and other performance are related, the greater the pressure, the higher the energy consumption, the greater the noise, and the stronger the vibration. Therefore, a vacuum fan with a suitable pressure should be selected according to the dust removal and dust removal needs of the field of use.
Second, how does the vacuuming high-pressure fan vacuum?
Large factories and other places use vacuuming fans, generally using vacuuming high-pressure fans. Many friends do not know much about the principle of vacuuming high-pressure fans. Here is a brief introduction for you:
The vacuuming principle of vacuuming high-pressure fans is: using high-pressure fan impellers to run at high speed to generate large suction and pressure , so that a partial vacuum is formed inside the vacuum cleaner. Under the action of suction and pressure, the air is discharged at a high speed, and the air in the vacuuming part at the front end of the high-pressure fan continuously replenishes the air in the fan, resulting in a short vacuum inside the vacuum cleaner, and the external Atmospheric pressure forms a negative pressure difference, long connecting pipes, hoses, elbows, and hose joints enter the dust filter bag, and dust and other sundries stay in the dust filter bag. After the air is purified by the filter, it is discharged from the air outlet at the rear of the body.
Third, the application field of industrial vacuuming high-pressure fans
Vacuuming high-pressure fans are widely used in industrial fields, in laser processing, batteries, semiconductors, electronics It is used in production lines of parts, automobiles, display screens, food, etc.:
1. Laser processing: including the dust removal treatment of laser cutting vehicle interior skins, and the dust removal treatment of smoke and dust generated by laser cutting lithium battery electrodes , Vacuum treatment of smoke and dust generated by laser cutting of polarizers, dust removal treatment during laser micro-processing of silicon chips, and dust removal treatment during chip marking.
2. Batteries: Dust removal of particles when cutting lithium battery electrodes, and dust removal of metal powders on the surface of lithium electrodes.
3. Semiconductors: electrostatic removal and dust collection of semiconductor components, electrostatic removal and dust removal of particles attached to electronic parts such as sensors and chips, and dust removal during laser microprocessing of silicon chips.
4. Electronic parts: After drilling or installing the printed circuit board, remove the dirt on the surface and vacuum; p>
5. Automobile: When the press-fit parts are assembled, the dust generated by friction is absorbed.
6. Display screen: The particles on the top, bottom, left and right of the film are removed.
7. Food: vacuuming and dusting of dirty packaging surfaces.
