The Know-How
More than decades of know-how in manufacturing for the compressed air market. World wide knowledge in different compressed air applications have guided the development of customer specified stationary screw compressors.

Technical Advancement for your Benefit
The advantage of CHINAMFG lies in its simplified construction. Fewer components are utilized. This means a 60% reduction in main and wearing parts and over 70% fewer pipes and connections. In turn, this greatly reduces the risk of leakages, making the system environmentally friendly. Safe direct drive operation without V-belt transmission.

The CHINAMFG CHINAMFG works in the following way:
Ambient air is drawn through the intake filter and the multifunctional control system into the CHINAMFG block. This block consists of a pair of screw rotors. The main rotor, driven by an electric motor, takes the secondary rotor with it. The air is drawn in by the rotation of both of the interlocking rotors and is continually compressed. During rotation, coolant is injected into the rotors and forms a hydrostatic film between the main and secondary rotors. The function of the coolant is to seal the rotors, lubricate the bearings and adsorb the compression heat. Before compressed air leaves the compressor ( at 80 ºC approx.) it is separated from the coolant before being cooled in the aftercooler to approx.. 8ºC to 12ºC above the ambient temperature. The coolant then passes to the thermostatic control block and filter, before entering the cooler where it is cooled from approx.. 80ºC down to 50ºC. It is then injected back into the CHINAMFG block.

What maintenance is required for air compressors?

Maintaining air compressors is essential to ensure their optimal performance, longevity, and safe operation. Regular maintenance helps prevent breakdowns, improves efficiency, and reduces the risk of accidents. Here are some key maintenance tasks for air compressors:

1. Regular Inspection: Perform visual inspections of the air compressor to identify any signs of wear, damage, or leaks. Inspect the compressor, hoses, fittings, and connections for any abnormalities. Pay attention to oil leaks, loose bolts, and worn-out components.

2. Oil Changes: If your air compressor has an oil lubrication system, regular oil changes are crucial. Follow the manufacturer’s recommendations for the frequency of oil changes and use the recommended oil type. Dirty or degraded oil can impact compressor performance and lead to premature wear.

3. Air Filter Cleaning or Replacement: Clean or replace the air filter regularly to ensure proper air intake and prevent contaminants from entering the compressor. Clogged or dirty filters can restrict airflow and reduce efficiency.

4. Drain Moisture: Air compressors produce moisture as a byproduct of the compression process. Accumulated moisture in the tank can lead to rust and corrosion. Drain the moisture regularly from the tank to prevent damage. Some compressors have automatic drains, while others require manual draining.

5. Belt Inspection and Adjustment: If your compressor has a belt-driven system, inspect the belts for signs of wear, cracks, or tension issues. Adjust or replace the belts as necessary to maintain proper tension and power transmission.

6. Tank Inspection: Inspect the compressor tank for any signs of corrosion, dents, or structural issues. A damaged tank can be hazardous and should be repaired or replaced promptly.

7. Valve Maintenance: Check the safety valves, pressure relief valves, and other valves regularly to ensure they are functioning correctly. Test the valves periodically to verify their proper operation.

8. Motor and Electrical Components: Inspect the motor and electrical components for any signs of damage or overheating. Check electrical connections for tightness and ensure proper grounding.

9. Keep the Area Clean: Maintain a clean and debris-free area around the compressor. Remove any dirt, dust, or obstructions that can hinder the compressor’s performance or cause overheating.

10. Follow Manufacturer’s Guidelines: Always refer to the manufacturer’s manual for specific maintenance instructions and recommended service intervals for your air compressor model. They provide valuable information on maintenance tasks, lubrication requirements, and safety precautions.

Regular maintenance is vital to keep your air compressor in optimal condition and extend its lifespan. It’s also important to note that maintenance requirements may vary depending on the type, size, and usage of the compressor. By following a comprehensive maintenance routine, you can ensure the reliable operation of your air compressor and maximize its efficiency and longevity.
