Reciprocating compressors use pistons driven by a crankshaft. They can be either stationary or portable, can be single or multi-staged, and can be driven by electric motors or internal combustion engines. Small reciprocating compressors from 5 to 30 horsepower (hp) are commonly seen in automotive applications and are typically for intermittent duty. Larger reciprocating compressors up to 1000 hp are still commonly found in large industrial applications, but their numbers are declining as they are replaced by various other types of compressors. Discharge pressures can range from low pressure to very high pressure (>5000 psi or 35 MPa).
Reciprocating Coders are used in inspection applications for automotive parts, plastic products and packaged items. These coders are all share clean inking systems that eliminate ink spills and messy marking stations. It utilizes non-toxic, solid ink, which is heated in a special cartridge.
Reciprocating compressor is a direct volume-reduction machine. It is a positive displacement compressor. Usually compressor takes refrigerant vapor at a low temperature & pressure and raises it to a higher level. Then it pumps refrigerant throughout the system. In the reciprocating compressor, a piston travels back and forth in a cylinder. A rod connects the piston to a crankshaft. As the motor turns, the crankshaft forces the piston up and down. A suction valve between the suction line and cylinder lets refrigerant vapor enter the cylinder during the suction stroke. The discharge valve between the discharge line and the cylinder lets refrigerant vapor exit the condenser during the discharge stroke. There are only two real problems with reciprocating compressors: pulsation and mechanical reliability.
