An ammonia compressor is a mechanical device specially designed to compress gaseous ammonia.Its main function is to compress low-pressure gaseous ammonia into high-pressure gaseous ammonia for further processing or storage in industrial processes.Ammonia compressor is widely used in chemical, refrigeration and freezing industries, especially in refrigeration system, it is an important equipment to compress gaseous ammonia into liquid ammonia.
Lubrication method: pressure type, splash type.
Product structure: single-cylinder vertical, double-cylinder vertical, symmetrical balance type.
Discharge volume : 0.2m3/min-10m3/min
Discharge pressure: from 0.8Mpa-2.6Mpa
It can meet the needs of different working conditions such as loading and unloading, conveying, flushing and loading, and process pressurization of tertiary stations, secondary stations, fire tanks, terminals, refilling stations, industrial stations and refineries in different regions and seasons.
Low-pressure gaseous ammonia enters the compressor's cylinder or compression chamber through the intake valve. During this phase, the piston or rotor of the compressor moves to increase the volume within the chamber, creating a vacuum that draws in the ammonia gas.
The ammonia gas is compressed as the piston, screw, or impeller reduces the volume of the compression chamber. As the volume decreases, the pressure and temperature of the ammonia gas increase significantly.
Once the ammonia gas reaches the desired pressure, the discharge valve opens, and the high-pressure gaseous ammonia is expelled from the compression chamber into the condenser. At this point, the chamber volume is at its minimum, forcing the gas out.
The high-pressure gaseous ammonia enters a condenser, where it is cooled and converted into liquid ammonia. This process usually involves circulating cooling water or air to remove the heat from the gas.
After condensation, the liquid ammonia is typically stored in a tank for use in refrigeration systems or other industrial applications. In refrigeration, the liquid ammonia evaporates to absorb heat, turning back into gaseous ammonia, which is then re-compressed by the compressor, continuing the cycle.

The core pressurisation equipment of the ammonia filling station is the diaphragm compressor. The diaphragm of the diaphragm compressor completely separates the cylinder from the oil cylinder, and the diaphragm chamber is well sealed to ensure the purity of ammonia.
Its working principle is that the diaphragm reciprocating movement when the oil pressure drops, so as to achieve the purpose of ammonia pressurisation.

The working principle of ammonia compressor is to use mechanical energy to turn the gaseous ammonia into a high -pressure liquid ammonia gas. The ammonia compressor includes a motor, reducer, condenser, and compressor. Gas ammonia enters the compressor from the power thermal exchange device, and a reducer is installed in the compressor to convert the high -speed rotation energy of the motor into a low -pressure liquid ammonia gas. The liquid ammonia is cooled by the condenser and stored in the storage tank.
