What problems are prone to small oil-free piston machines? Screw Air Compressor has advantages over piston air compressorStructure and working principle1. piston oil-free air compressorThe piston oil-free lubrication air compressor consists of the main compressor, cooling system, adjustment system, lubrication system, safety valve, motor and control equipment. The compressor and motor are fastened to the seat by bolts, and the seat is fixed on the basis by anchor bolts. When working, the motor directly drives the crankshaft through the shaft connector, driving the connecting rod, cross head and piston rod, so that the piston can perform reciprocating movement in the cylinder of the compressor, and complete the process of suction, compression and discharge. The machine is a double-acting compressor, that is, the piston moves upward and downward with air suction, compression and discharge.2. Screw Air CompressorThe Screw Air Compressor consists of screw head, motor, oil and gas separation barr
