Maximizing Performance & Reliability

Turbines sit at the heart of power generation and critical industrial processes. High temperatures, vibration, and continuous load cycles demand disciplined care to keep output high and trips low. Bunney’s Inc. delivers inspection, maintenance, repair, and optimization for gas, steam, hydro, and mechanical-drive turbines across Arizona and the Southwest—with schedule discipline and audit-ready documentation.

What’s Included in Turbine Support

  • Routine & Preventive Maintenance: Scheduled inspections, borescope, clearances, filter/strainer service, torque checks, and fastener audits.

  • Emergency Repair & Troubleshooting: Rapid diagnostics, component swaps, and safe return-to-service procedures.

  • Component Replacement: Blades/buckets, bearings, seals, nozzles/vanes, couplings, and packs.

  • Alignment & Balancing: Laser alignment, soft-foot correction, in-place dynamic balancing, and run-out verification.

  • Performance Upgrades: Controls tuning, seal/clearance improvements, insulation and casing leakage fixes, and auxiliary system optimization.

  • Field Services: On-site machining, controlled bolting/torque, flange facing, and start-up assistance.

    Why Proactive Turbine Care Matters

    • Higher efficiency & output: Tighter clearances and balanced rotors reduce losses.

    • Fewer trips & forced outages: Early defect detection prevents cascading failures.

    • Lower lifecycle cost: Condition-based work stretches major-overhaul intervals.

    • Safety & compliance: Procedures align to site rules with documented QA/QC.

    Diagnostics & Condition Monitoring (PdM)

    • Vibration analysis & trending (overall, spectrum, phase)

    • Borescope inspections of hot-gas path and steam path components

    • Thermography for bearings, casings, and auxiliaries

    • Lube-oil analysis (viscosity, TAN/TBN, particle counts, wear metals)

    • Performance testing (heat rate, efficiency indices, backpressure/DP checks)

    Findings map to a prioritized corrective-action plan and outage window.

    Arizona-Specific Considerations

    • High ambient heat: Bearing and lube-oil cooling checks, insulation upgrades, and enclosure ventilation.

    • Dust & sand: Inlet filtration, seal/labyrinth protection, and cleanliness standards for assemblies.

    • Monsoon moisture: Corrosion control, drainage, and enclosure integrity.

    • Peak demand windows: Outage planning around summer loads and rapid mobilization for forced events.

    Industries We Support

    • Power Generation: Gas and steam turbines with HRSG/boiler interfaces.

    • Industrial Manufacturing: Mechanical-drive turbines for compressors and large rotating equipment.

    • Oil & Gas / Midstream: Turbine drives, boosters, and power islands.

    • Renewables & Hydro: Runner/blade, gearbox, and generator support.

    • Outage-ready mobilization with schedule discipline and site safety training

    • Transparent documentation for audits and continuous improvements

    FAQs

    Do you perform in-place rotor balancing?
    Yes—our teams conduct in-situ dynamic balancing, then verify with post-balance vibration data.

    How often should we borescope a gas turbine?
    Depends on runtime and fuel quality; many sites target every 8,000–12,000 hours or at defined inspection intervals.

    Can you support start-up after a hot gas path inspection?
    Yes—alignment checks, leak tests, vibration baselines, and controls tuning with documented acceptance criteria.

    What typically causes repeat bearing failures?
    Common root causes are misalignment, lubrication issues, contamination, or electrical fluting; we pair repair with program fixes to prevent recurrence.

    Do you work during peak season?
    We plan around Arizona summer demand, prioritizing pre-season maintenance and rapid response for forced outages.
