Our Sweep Gauge is a precision mechanical tool designed for measuring stator roundness, deformation, and radial clearances in large hydro generators. It ensures accurate alignment diagnostics during installation, maintenance, or overhaul of rotating machines.
Key Features
- Application:
Used for radial measurement and roundness checking of stator bore in large hydro generators. - Construction:
- Rigid and lightweight frame suitable for easy rotation inside the stator.
- Compatible with multiple rotor sizes and bore diameters.
- Calibrated arm extensions for accurate reach and measurement.
- Rigid and lightweight frame suitable for easy rotation inside the stator.
- Mounting:
The gauge is designed to be mounted at the centre axis of rotation, referencing the rotor/stator axis during measurement
Measurement Layout
- The sweep gauge consists of:
- A rotating central axis arm
- Adjustable measuring arms.
- Provision for dial gauge/micrometer fitting
- A rotating central axis arm
- Full 360° sweep possible to collect measurement points across stator bore circumference.
Accuracy & Benefits
- Enables precise identification of:
- Out-of-roundness.
- Deformation or shifting of stator lamination stacks.
- Radial eccentricity or misalignment.
- Out-of-roundness.
- Reduces commissioning and maintenance errors by providing reliable measurement data.
Customization Options
- Can be designed for specific stator bore sizes and configurations..
- Portable packing for easy site transport and handling..
