Exhaust Pressure: The maximum working pressure produced by the compressor, measured in megapascals (MPa).
Exhaust Flow Rate: The volume of air the compressor can supply per minute, measured in cubic meters per minute (m³/min).
Power Requirement: The electrical power required to operate the compressor, usually measured in kilowatts (kW).
Energy Efficiency Ratio: An assessment of compressor efficiency, expressed as the ratio of compressed air output to electrical power input.
Temperature Range: The normal operating environmental and exhaust temperatures of the compressor, measured in degrees Celsius (°C).
II. Testing Methods
To ensure that screw air compressors meet quality standards, the following testing methods are used:
Exhaust Flow Rate Test: Performed using a standard flow meter.
Pressure Test: Continuous monitoring with high-precision pressure sensors.
Power Test: Measurement of actual power consumption using power meters.
Energy Efficiency Test: Calculation of the ratio between input power and output flow rate.
Temperature Monitoring: Using temperature sensors to detect compressor and ambient temperatures.
III. Quality Requirements
Screw air compressors should meet the following quality requirements during design and manufacturing:
Standard Compliance: Manufactured strictly in accordance with national and international standards, such as ISO 1217.
Performance Guarantee: Ensures long-term stable operation with efficient compression capability and energy efficiency.
Complete Documentation: Provision of comprehensive product manuals, operating guides, and maintenance records.
Safety Compliance: Complies with national safety production regulations, equipped with necessary safety devices.
Environmental Certification: Meets environmental standards, such as ISO 14001, ensuring low emissions and noise.
IV. Common Issues and Solutions
Common problems and their solutions in the use of screw air compressors include:
High Temperature: Enhance cooling systems, regularly clean radiators, and replace coolant.
Noise Issues: Check and adjust internal mechanical parts to ensure adequate lubrication and reduce wear.
Insufficient Exhaust Flow: Regularly inspect and clean or replace air filters to ensure unobstructed airways.
Decreased Energy Efficiency: Regularly perform energy efficiency assessments, optimize system settings, and maintain or replace inefficient components.
By adhering to these standards and methodologies, screw air compressors can be ensured to operate efficiently, reliably, and safely, while meeting the air compression demands of industrial applications.
