What is the difference between reciprocating compressor and turbo compressor?

Answer:

The turbo compressor is developed on the basis of ventilators. It is widely used in various processes to transport air and various gases, and to increase its pressure.
Reciprocating compressor is a displacement compressor. It is a compressor that makes a certain volume of gas sequentially inhale and exhaust the enclosed space and increase the static pressure.
Turbo compressor is a power compressor with high speed rotating impeller. It depends on the interaction between the rotating impeller and the air flow to increase the gas pressure, and make the airflow acceleration to obtain kinetic energy, then flow deceleration in the diffuser, the kinetic energy into pressure energy, to further improve the pressure. In compression, the flow of gas is continuous.
Reciprocating compressor is driven by the crankshaft connecting rod, connecting rod to drive the piston, piston up and down movement. The movement of the piston within the cylinder volume change when the downward movement of the piston, the cylinder volume increases, the intake valve opens, the exhaust valve is closed, air is sucked in, complete the intake process; when the piston upward movement of the cylinder volume decreases, the outlet valve open, inlet valve closed, complete compression process. Usually, the piston has a piston ring to seal the gap between the cylinder and the piston. There is a lubricating oil piston ring in the cylinder.
