Advanced scroll compression technology
The unique working principle of scroll compression technology gives CHINAMFG KC series compressors unique energy efficiency advantages. The air compression process is achieved by the mutual movement of the fixed scroll and the moving scroll. Air enters from the outer side of the nose. Once the air is sucked in, the moving scroll closes the air inlet. As the moving scroll moves When rotating, the air is gradually compressed, and continuous compressed air is discharged from the center of the static scroll.
This process is repeated continuously, so that the discharged air is always continuous without fluctuations.

Start by gathering relevant information about the compressor system and the specific issue you are experiencing. This may include the compressor model and specifications, maintenance records, any error codes or warning messages displayed, and a description of the problem and its symptoms.
Step 2: Visual Inspection:
Perform a visual inspection of the compressor system. Look for any obvious signs of damage, leaks, loose connections, or unusual noise or vibrations. Check the air intake and exhaust vents for blockages or obstructions. Inspect the control panel and electrical components for any visible issues.
Step 3: Check Power and Controls:
Ensure that the compressor system is receiving proper power supply and that all electrical connections are secure. Check the control settings and adjust them as needed. Verify that any safety switches or interlocks are properly engaged. Test the system with different control settings to see if the issue persists or changes.
Step 4: Review Maintenance and Service Records:
Review the maintenance and service records of the compressor system. Check if any scheduled maintenance tasks, such as filter replacements or lubricant changes, are overdue. Ensure that the system has been properly serviced according to the manufacturer’s recommendations. Improper maintenance or missed service tasks can contribute to performance issues.
Step 5: Monitor Operating Parameters:
Monitor the operating parameters of the compressor system during normal operation. This may include measuring and recording variables such as discharge pressure, suction pressure, motor current, and temperature. Compare these parameters to the manufacturer’s specifications or known good values to identify any deviations that may indicate a problem.
Step 6: Analyze Error Codes or Alarms:
If the compressor system displays error codes or alarms, consult the system’s documentation or user manual to understand their meaning. Error codes can provide valuable information about the specific nature of the issue. Troubleshoot and address the underlying cause of the error code or alarm according to the manufacturer’s instructions.
Step 7: Inspect and Clean Filters:
Check and clean the air intake filters, oil filters, and any other filtration components in the system. Clogged or dirty filters can restrict airflow and cause performance issues. Follow the manufacturer’s guidelines for filter cleaning or replacement. Ensure that the filters are properly installed after cleaning or replacement.
Step 8: Verify Lubrication System:
If applicable, verify the lubrication system of the compressor. Check the oil level and ensure that it is within the recommended range. Inspect the oil cooler, oil lines, and oil filter for any leaks, blockages, or damage. Ensure that the lubricant used is of the correct type and viscosity specified by the manufacturer.
Step 9: Check Cooling System:
Inspect the cooling system of the compressor, including the air or water cooling components. Make sure that the cooling system is functioning properly and that there are no obstructions or restrictions in the airflow or water flow. Clean any accumulated dirt or debris from the cooling fins or heat exchangers.
Step 10: Consult Manufacturer’s Documentation:
If the issue persists or if you are unable to identify the problem, consult the manufacturer’s documentation, such as the user manual or troubleshooting guide. These resources often provide specific troubleshooting steps and solutions for common issues with the oil-free scroll compressor system. Follow the manufacturer’s recommendations and contact their technical support if necessary.
It’s important to note that troubleshooting and maintenance of oil-free scroll compressor systems may require specialized knowledge and expertise. If you are not familiar with the specific equipment or troubleshooting procedures, it is recommended to consult a qualified technician or contact the manufacturer’s technical support for assistance.
In summary, troubleshooting common issues with oil-free scroll compressor systems involves gathering information, performing visual inspections, checking power and controls, reviewing maintenance records, monitoring operating parameters, analyzing error codes, inspecting and cleaning filters, verifying the lubrication system, checking the cooling system, and consulting the manufacturer’s documentation.
