Why Do Air Compressors Need a Thermostat Valve?
Release time:
2025-08-18
In a screw air compressor, there’s a small but very important component – the thermostat valve. Its job is to regulate the oil temperature, making sure the compressor doesn’t “freeze” when it’s cold or “burn out” when it’s hot.
How does it work?
The principle is simple: the thermostat element expands or contracts with temperature changes, which drives the valve core to open or close.
When it’s cold: the lubricating oil flows directly into the air end, ensuring proper lubrication during startup.
When it’s hot: the valve opens gradually, sending more oil to the cooler for temperature reduction.
This keeps the compressor running at just the right temperature range.
Why is it essential?
· Protects the machine: prevents damage from overheating or poor lubrication.
· Extends service life: ensures stable operation and reduces costly overhauls.
· Keeps oil in good condition: prevents emulsification, oxidation, and carbon buildup.
· Saves energy: adjusts oil flow intelligently, reducing unnecessary energy loss.
· Stabilizes discharge temperature: ensures reliable and efficient performance.
