Constant Pressure Springs for Generator Units QFS-300-2

Constant pressure springs are mainly used in the brush holders of generator sets QFS-300-2 to ensure constant contact pressure between the carbon brushes and the slip rings.

Functions and Characteristics of Constant Pressure Springs

• Maintain stable pressure: Their design allows them to automatically adjust pressure as the carbon brush wears down, keeping the contact pressure stable.
• Temperature stability: Made from a constant-elasticity alloy, their elastic modulus remains nearly constant over a certain temperature range, ensuring stable contact pressure regardless of temperature changes.
• Improving reliability: Stable pressure output and temperature stability help reduce poor contact between the carbon brushes and the slip rings, improving the reliability and efficiency of the generator set.
