What is the air compressore gets very hot after 10 hours working?

 

Here are the most common causes, categorized from simplest to most complex:

1. Cooling and Ventilation Issues (Most Common)

  • Poor Ventilation: The compressor is installed in a confined, hot, or poorly ventilated room with no fresh air circulation. It needs cool intake air to function correctly.
    • Solution: Ensure the compressor has ample space (at least 1 meter on all sides), especially around the air intake and cooling fins. Move it to a cooler, well-ventilated location.
  • Clogged Cooling Fins/Ribs: The radiator fins (often located around the cylinder) are blocked with dust, dirt, oil, and debris. This acts like an insulator, preventing heat from escaping.
    • Solution: With the power off, thoroughly clean the cooling fins using compressed air or a soft brush. Ensure the air passage is completely clear.
  • Faulty Cooling Fan: The fan may be running slow, not running at all, or its blades may be damaged. In belt-driven models, the belt could be loose or slipping.
    • Solution: Check the fan motor, power supply, and blades. For belt-driven models, tighten or replace the belt.

2. Lubrication Problems (Critical)

  • Low or High Oil Level:
    • Low Oil: Insufficient oil means there's not enough fluid to carry heat away from the piston and cylinder, leading to rapid temperature rise and severe wear.
    • High Oil: Excess oil causes increased fluid friction (churning) and resistance, which also generates excessive heat.
    • Solution: Check the oil sight glass when the compressor is off. The oil level must be between the "Min" and "Max" marks. Always use the manufacturer-recommended type and viscosity of compressor oil.
  • Degraded or Incorrect Oil: Over time, oil oxidizes, contaminates, and loses its lubricating and cooling properties. Using the wrong type of oil (e.g., automotive motor oil) can cause carbon buildup and poor performance.
    • Solution: Change the oil according to the manufacturer's service interval (e.g., every 500-800 hours). If the oil is dark, thick, or has a burnt smell, change it immediately.

3. Air Intake and System Pressure Issues

  • Clogged Air Filter: A dirty air filter restricts intake air. The compressor has to work much harder (higher load) to draw in air, generating more heat for the same amount of output.
    • Solution: Clean or replace the air filter. In dusty environments, this needs to be done more frequently.
  • Faulty Valves (Inlet/Discharge): Worn, broken, or leaking valve plates/springs reduce compression efficiency. Air can be trapped and re-compressed within the cylinder, creating massive amounts of excess heat.
    • Symptoms: Longer cycle times to reach pressure, increased electricity consumption, and high temperatures.
    • Solution: This requires a professional technician to inspect and rebuild or replace the valve assembly.
  • High Operating Pressure: The pressure switch might be set too high, forcing the compressor to operate beyond its design limits.
    • Solution: Check and adjust the cut-out pressure to the compressor's specified rating.

4. Mechanical Wear

  • Worn Piston Rings or Cylinder: Over time, these components wear out, causing internal blow-by (air leaking past the piston). This drastically reduces compression efficiency and increases heat generation.
    • Solution: This is a major overhaul requiring disassembly and replacement of parts by a qualified technician.
