Component Specifications

Definition

Support feet are engineered mounting components designed to securely anchor turbine casings to foundations while managing operational loads, thermal expansion, and vibration transmission. They ensure proper alignment, distribute weight evenly, and prevent stress concentrations that could compromise casing integrity or turbine performance.

Working Principle

Support feet function by transferring static and dynamic loads from the turbine casing to the foundation through rigid or adjustable connections. They incorporate features like leveling pads, vibration dampers, or thermal expansion allowances to maintain stability under varying operational conditions, preventing misalignment and reducing mechanical stress.

Materials

Typically forged or cast steel (e.g., ASTM A36, AISI 4140), stainless steel (e.g., 304/316) for corrosive environments, or high-strength alloys; may include elastomeric or composite inserts for vibration damping.

Frequently Asked Questions

What is the primary function of support feet in a turbine casing?

To provide a stable foundation, distribute operational loads, and isolate vibrations to protect the turbine and surrounding infrastructure.

How do support feet accommodate thermal expansion in turbines?

Through adjustable mounts or sliding interfaces that allow controlled movement without inducing stress, often designed per thermal expansion coefficients of materials.
