Single and Double Stage Reciprocating Air Compressors COMPRESSOR BLOCK • Heavy duty cast-iron crankcases contain properly placed oil level indicators, oil filling/draining plugs and crankcase ventilation system. • Cast-iron cylinders and bare pumps with cooling fins help the system preventing overheat • Dynamically balanced and precisely manufactured sphero cast crankshafts provide long lifecycle. • Lightweight pistons and connecting rods casted from special aluminum alloy not only apply less pressure to crankshaft but also prevent it from overheating with high heat transfer capability • Special design finger-type high capacity and high pressure-resistant inlet-outlet valves made from stainless steel are capable of holding airflow in upper levels as well as operating at high temperatures. • Compression and oil retaining rings are used for holding the airflow maximized and preventing oil leakages. MAIN MOTOR AND DRIVE SYSTEM • High efficiency IE2 class IP55 motors working with 380V/3 phase/50Hz power inlet are used as a standard in reciprocating air compressors. • Driving the crankshaft is realized by a belt-pulley mechanism placed between compressor block and main motor and selected considering a suitable transmission ratio. • Belts are chosen by considering the working life of minimum 25,000 hours. • Special design fan type cast-iron pulleys not only provide airflow with large volumes to cool compressor block but also act as a flywheel to damp the vibrations occurred during operation. • With easy adjustment of belt tension, continuously efficient operation SAFETY SYSTEMS • The solenoid valve for loadless start (for 4kW motor power and more) • Pressure switch • Non-return valve • Belt-pulley guard • Safety valve
