Oil free compressor working principle:

Oil free compressor working principle:

Oil-free air compressor is miniature reciprocating piston compressor, motor single shaft drive compressor crankshaft rotates, through connecting rod drive, has the self-lubricating without adding any lubricant piston reciprocating motion, it consists of the inner wall of the cylinder, cylinder head and piston top surface of working volume will change periodically. Piston compressor piston from cylinder head start, the work within the cylinder volume increases gradually, at this time, the gas along the inlet pipe, pushed open the inlet valve into the cylinder, until the work gets to maximum volume, the inlet valve close; Reverse movement, piston compressor piston within the cylinder working volume shrinking, gas pressure, when the pressure in the cylinder is achieving and slightly higher than the exhaust pressure, the exhaust valve opens, the gas discharge cylinder, until the piston movement to the limit position, the exhaust valve closed. When piston compressor piston backward movement again, this process is repeated. Namely: piston compressor crankshaft rotates, the piston reciprocating at a time, one after another in the cylinder to realize the process of air intake, compression, exhaust, to complete a working cycle. Uniaxial duplex structure design of compressor gas flow at rated speed must be twice of the cylinder, and get a good control on vibration noise control.

The whole machine working principle:

The motor running, the air through the air filter into the compressor, the compressor will be compressed air, compressed gas by airflow pipe open the check valve into the storage tanks, pressure gauge pointer display, rise to eight Bar. Greater than 8 Bar, automatically shut down after the pressure, pressure switch induced motor to stop working, and at the same time, the electromagnetic valve will be pressure to the compressor head 0. The air pressure switch to assert, propane tanks still is 8 Bar, gas pressure in the gas through ball valve exhaust drive connection equipment work. Pressure drop to 5 Bar in the store jar, pressure switch open automatically by the induction, the compressor went back to work.
