The main functions of Atlas Copco screw air compressor regulators:
Pressure control: By setting upper and lower pressure limits, when the system pressure reaches the upper limit, the regulator will stop the operation of the air compressor or unload it; when the pressure drops to the lower limit, it will restart or load it to ensure stable output pressure.
Energy-saving operation: Avoid frequent start-stop of the air compressor or continuous full-load operation, reducing energy waste and extending equipment lifespan.
Safety protection: When the pressure exceeds the safety threshold, some regulators will trigger the safety valve to release gas, preventing system overpressure damage.
Flow regulation: According to the demand of the gas-using equipment, adjust the output flow of compressed air to match the actual load.
Common types:
Mechanical pressure regulator:
Uses mechanical structures such as springs and diaphragms to sense pressure changes, and controls the loading/unloading or start/stop of the air compressor through mechanical linkage.
Simple structure, low cost, suitable for small and medium-sized air compressors.
Electronic pressure regulator:
Uses pressure sensors to detect pressure, and uses electronic components such as microcontrollers for logical judgment, and outputs signals to control the operation of the air compressor.
Higher precision, capable of digital setting and remote control, suitable for large or highly automated systems.
Variable frequency regulator:
Combines with frequency converters, adjusts the exhaust volume of the air compressor by changing the motor speed, keeping the output pressure stable.
Significantly energy-saving, especially suitable for scenarios with large fluctuations in gas usage.
Key parameters:
Range of regulation: The set pressure range, which needs to match the rated pressure of the air compressor and the demand of the gas-using equipment.
Precision: The deviation range between the actual pressure and the set pressure, electronic types are usually higher than mechanical types.
Response speed: The reaction time of the regulator when pressure changes, affects system stability.
Interface type: The connection method with the air compressor and pipelines (such as threaded connection, flange connection, etc.).
