Screw air compressors can heat up rapidly—often beyond 200°C (392°F)—before operators even notice. While these machines are essential to industrial production, their high-power operation and pressurized systems mean safety should never be underestimated.
In some rare cases, high-temperature shutdowns or even fire hazards can occur if proper safety protocols are not followed. To ensure both safety and efficiency, compressor operators must stay vigilant and follow expert recommendations.
⚡ Why Screw Compressors Are Prone to Overheating
Even under normal use, rapid temperature rises in screw compressors are not unusual. These rises may result from:
- Harsh operating environments
- Component wear or failure
- Improper safety configurations
If these issues are ignored, uncontrolled overheating or combustion risks may arise, especially in high-dust or explosive environments like coal processing or underground mining.
🛡️ Key Safety Recommendations for Screw Compressors
1. Reliable Motors and Instruments Are the First Line of Defense
- Use motors with a minimum IP44 protection rating. This prevents conductive dust from entering and causing electrical leakage or short circuits.
- In high-risk areas (e.g., coal chemical plants, graphite processing), ensure anti-static and explosion-proof protection.
- Avoid excessive exhaust temperatures. While higher temps can prevent oil emulsification, they accelerate oil degradation 그리고 increase power consumption.
2. Don’t Overlook the Minimum Pressure Valve
One of the most common yet overlooked hazards is minimum pressure valve failure. These failures are typically caused by:
- Valve core jamming due to wear, debris, or tight tolerances
- Poor material pairing (e.g., identical aluminum alloys for the core and seat), leading to galling or seizure
Regular inspection and using high-quality OEM components can prevent serious failures.
3. Secure the “Safety Door” with These Operational Habits
- ✅ Ensure the oil injection system is smooth and free of blockages or faulty valves (e.g., solenoid valves that may fail).
- ✅ Use certified temperature switches, controllers, and electrical cabinets from trusted manufacturers.
- ✅ Schedule routine testing of temperature sensors and controllers to verify reliability and accuracy.
These practices may seem excessive at first glance, but compared to the cost of equipment failure or fire hazards에서 return on safety investment is massive.
🔁 Safety and Efficiency: Two Sides of the Same Coin
In the age of intelligent and energy-efficient compressors, energy savings and safety are two sides of the same operational coin. Behind every smile a compressor brings to your production line lies a balancing act between:
- Efficiency vs. waste
- Safety vs. risk
By proactively securing your “safety door,” you not only extend equipment lifespan, but also protect personnel and production uptime.
