The oil-free air compressor works through the following principles and operation modes:
motor drive:
oil-free air compressors are usually powered by electric motors. In particular, the permanent magnet synchronous motor drives the compressor to rotate at a high speed.
Air intake:
during operation, the outside air enters the cylinder of the air compressor through a specific filter element.
Compressed air:
when air enters the cylinder, it is compressed to a higher pressure by internal mechanisms (such as screws). The design of these screws allows them to rotate at high speeds and are very close, but not in direct contact, thereby eliminating the need for lubricating oil.
Exhaust:
the compressed air is gradually squeezed out of the cylinder after being compressed. The compression process raises the temperature of the air, but then it is cooled by a radiator to reduce the temperature.
Working cycle:
the working cycle of oil-free air compressor usually includes three stages: suction, compression and exhaust. For example, in a piston-type oil-free air compressor, when the piston moves backward, the working volume in the cylinder increases, the suction valve opens, and air enters the cylinder; as the piston moves forward, the air in the cylinder is compressed. When the pressure reaches a certain level, the exhaust valve opens and the compressed air is discharged.
Control system:
the oil-free air compressor is also equipped with a pressure control system, which can monitor and adjust the pressure in the air tank. When the pressure reaches the set value, the compressor will automatically shut down; when the pressure drops to a certain level, the compressor will restart to ensure that the pressure in the gas storage tank is stable within the required range.
In summary, the oil-free air compressor is mainly driven by an electric motor, and continuous operation is realized through the steps of air intake, compressed air, exhaust and pressure control. This mode of operation allows the oil-free air compressor to provide compressed air in an efficient and environmentally friendly manner without the need for lubricating oil.
