A reciprocating nitrogen compressor is a device that compresses nitrogen by reciprocating the piston in the cylinder. With its simple structure, high compression efficiency and wide pressure range, it is widely used in many fields such as chemical industry, food, electronics, energy, etc. The following is a detailed introduction from the aspects of working principle, main features, core parameters, applicable scenarios and maintenance points:
I. Working principle
The core of the reciprocating nitrogen compressor is the piston-cylinder structure, and nitrogen compression is achieved through the following steps:
Inhalation stage: The piston moves downward, the volume in the cylinder increases, the pressure decreases, and the nitrogen enters the cylinder through the suction valve.
Compression stage: The piston moves upward, the suction valve closes, the volume in the cylinder decreases, the nitrogen is compressed, and the pressure increases.
Exhaust stage: When the pressure in the cylinder reaches the exhaust pressure, the exhaust valve opens, and the high-pressure nitrogen is discharged into the subsequent pipeline or storage equipment.
Through the reciprocating cycle of the piston, the low-pressure nitrogen is continuously compressed to the required high pressure. The whole process relies on the crank-connecting rod mechanism to convert the rotational motion of the motor into the linear reciprocating motion of the piston.
