Have Steam Turbines Regularly Inspected For Efficient Performance
Steam turbines work towards transforming the superheated or saturated boiler steam into mechanical rotating motion to generate power. The steam turbines drive equipment of different types, sizes, and speeds. The different kinds of industries that benefit from steam turbines involve power generation, paper & pulp, chemical, oil & gas, iron & steel, etc.
Even though there is a considerable difference in application, complexity, design, size, and steam conditions, the concept of all the steam turbines is the same. They use the same major components, same supporting system, same functionality, and experience the same mechanism defects. For reliable turbine operation support, there is a need for regular inspection of the system by industry professionals.
How regular maintenance programs from professional inspection services help?
Regular maintenance from turbine inspection services ensures that the steam turbine operates reliably and efficiently. A regular maintenance program ensures maximum system uptime as well as early detection of potential issues. An inspection conducted with a borescope camera is superlative. It is a less invasive method for turbine inspection.
A long, flexible cable housing a camera at its tip is slithered down the steam turbine to investigate issues like cracks or spill pats failure, etc. Onsite inspections offer necessary outcomes and failure to risk analysis. The professionals notify the possibility of risks that can impact the steam turbine operations along with suggestions for repair or replacement.
How professional technicians perform regular maintenance?
The professional technicians visually inspect the generator to find out if –
- Visually inspect the bearing and seal housing for leaks and wear.
- The oil level is proper
- There are steam deposits
- There is oil, water, or steam leakage
- All the valves are positioned correctly
- The condition of all the control & trip, conduit, insulation, wiring, instrumentation, etc.
- Check safety devices
- Check over speed trip
- Review the records and discuss operating issues experienced since last repair or inspection
The main aim of the turbine inspection contractor is to keep customer’s equipment in top-notch condition. You can rely on their skills and knowledge associated with turbine issue diagnosis and troubleshooting.
With advanced technology, monitoring is a must
The technologies incorporated in designing the steam turbines are sophisticated and need to operate at high temperatures and pressures. Even though technology has enhanced the operation, the inherent risk exposure has increased, so you need to carefully monitor the steam turbine operation.
The frequency of the maintenance tasks needs to get prioritized towards the steam turbine components carrying high risks. It means protecting steam turbines from –
- Lube oil loss
- Over speeds
- Corrosive steam
- Water induction
- Sticking valves
Therefore, have professionals conduct an internal inspection of the turbines flow path, rotors, and shells for defective damage like erosion, creep, thermal fatigue, or corrosion. If the fault is detected early you can prevent an ensuing major failure. It is also crucial that your staff get consistent training in operating and maintaining the complex steam turbine system.
Whenever you notice some turbines not functioning effectively schedule a professional inspection as soon as possible. You get the issue diagnosed and machine retrieved for optimal performance.
