Oil-free scroll air compressor for new energy vehicles
Oil-free scroll air compressors are core components of the air supply system for braking, air suspension, and other systems in new energy vehicles (especially commercial vehicles). They are suitable for pure electric, hybrid, and fuel cell vehicles, replacing traditional oil-lubricated piston compressors.
Its core principle relies on a pair of precisely meshing moving and stationary scrolls: the stationary scroll is fixed, while the moving scroll rotates around its center without rotating on its own axis, continuously forming a crescent-shaped sealed air chamber. Air is drawn in through the inlet, smoothly compressed as the air chamber volume contracts towards the center, and finally discharged from the central outlet. Single-stage compression can reach 12.5 bar, delivering continuous, pulse-free, pure air.
This compressor boasts four major advantages:
First, it features a completely oil-free design with a non-contact scroll seal, eliminating the need for lubrication, preventing oil leaks and fire risks, and ensuring clean compressed air to meet vehicle safety requirements.
Second, it operates quietly with low vibration, eliminating reciprocating impacts; the rated operating noise is approximately 65-67 decibels, close to normal conversation, enhancing driving comfort.
Third, it is highly efficient and energy-saving, with an integrated motor drive supporting speed changes and intermittent stopping, resulting in low energy consumption and contributing to improved vehicle range.
Fourth, it is lightweight and reliable, with a compact structure and fewer parts; the main body is made of aluminum, weighing approximately 35-40 kg, meeting the lightweight requirements of vehicles, and can withstand extreme environments from -40℃ to 60℃, resulting in long maintenance intervals and reduced maintenance costs.
Currently, it is widely used in new energy buses, logistics vehicles, heavy trucks, and other vehicle types, and is one of the key components in the electrification transformation of new energy vehicles.
