1.Screw Air Compressors:Regularly Check and Replace Filters Screw Air Compressors
Air Filter Element:
- Function: Filters dust and impurities from the air to prevent them from entering the air compressor.
- Maintenance: Check and clean regularly (e.g., weekly) and replace according to usage, generally after 1500 hours of work.
Lubricating Oil Filter Element:
- Function: Filters impurities from the lubricating oil to maintain its cleanliness.
- Maintenance: After the running-in period of new equipment (about 500 hours), check regularly (e.g., every 2000 hours) and replace as needed.
2.Screw Air Compressors:Cleaning and Maintenance of the Cooling System
Cooler:
- Function: Ensures good heat dissipation.
- Maintenance: Clean regularly to remove dust and oil from the surface. The cleaning cycle can be based on operating and environmental conditions, generally recommended every 2000 hours.
Fan:
- Function: Maintains good heat dissipation performance.
- Maintenance: Check and clean regularly to ensure normal operation.
3. Check and Replace Lubricating Oil
Lubricating Oil:
- Function: Ensures lubrication and normal operation of internal parts.
- Maintenance: Replace regularly and change the lubricating oil filter simultaneously to avoid mixing old and new oil. Do not mix different types of lubricating oils.
Oil-Gas Separator:
- Function: Separates oil and dirt from compressed air.
- Maintenance: Check and clean regularly (e.g., every 3000 hours) to ensure normal separation effect.
4. Check and Calibrate the Control System
Control System:
- Function: Monitors and controls the operating status of the equipment.
- Maintenance: Check and calibrate regularly to ensure accuracy and reliability.
5. Other Maintenance Measures
Electrical System:
- Function: Ensures firm connections and good condition of wiring terminals.
- Maintenance: Regularly check power cords and control lines.
Belt:
- Function: Drives the system.
- Maintenance: Check for looseness or wear and replace if necessary.
Complete Machine Operation Test:
- Function: Evaluates performance and operating status of the equipment.
- Maintenance: Perform regularly to identify and resolve issues promptly.
6. Safety Precautions
- Qualified personnel must perform compressor operation, repair, and maintenance.
- Ensure the compressor motor rotates in the correct direction before starting.
- Allow high-temperature components to cool to ambient temperature before removal.
- Use genuine spare parts, as original components are specially designed and manufactured.
- Do not block the compressor suction port during operation.
- Do not use compressed air for breathing unless explicitly indicated as safe.
- Do not operate the compressor under conditions exceeding specified pressure and temperature.
- Immediately stop the compressor and address any abnormal working conditions.
Summary
Maintaining screw air compressors involves various tasks, including regular inspection and replacement of filters, cooling systems, lubricating oils, and control systems. Other essential maintenance measures include checking the electrical system, belts, and conducting whole machine operation tests. Adhering to safe operating specifications ensures that the compressor remains in a safe and efficient state, providing reliable performance over time
