The purpose of vacuum pumps is to create or maintain a vacuum environment in a specific space by extracting gas. They are widely used in industrial manufacturing, medical equipment, semiconductor production, agricultural research and environmental protection operations.
Main application areas and specific uses
Industrial manufacturing
Metallurgical industry: used for vacuum smelting, metal heat treatment and other processes to improve material performance.
Chemical and pharmaceutical: to ensure an oxygen-free environment in processes such as vacuum drying, distillation, and reaction vessel exhaust.
Electronics and electricity: used for transformer vacuuming, vacuum coating, and electronic component manufacturing.
Semiconductor manufacturing: to provide high vacuum in processes such as photolithography, ion implantation, and thin film deposition to ensure product quality (screw vacuum pumps are widely used due to their oil-free pollution characteristics).
Medical field
Equipment maintenance: clean the tiny pipes inside medical instruments to ensure the normal operation of the equipment.
Surgical assistance: for example, extract excess fluid in ophthalmic surgery to provide a clear view.
Agricultural research
Seed preservation: reduce seed respiration through a vacuum environment to extend the shelf life.
Precision planting: Vacuum the plant cultivation bag to optimize the root growth microenvironment.
Environmental protection operation
Assist in extracting gas when processing environmental samples for analysis or storage.
Targeted applications of different types of vacuum pumps:
Low vacuum pumps (such as water ring and liquid ring) are suitable for scenes with rough vacuum requirements, such as food packaging.
High vacuum pumps (such as diffusion pumps and molecular pumps) are used in fields such as semiconductor manufacturing that require extremely high vacuum.
Oil-free vacuum pumps (such as screw type) are the first choice for medical and precision industries due to their clean properties.
