Turbolader · Turbolader
This centrifugal compressor is designed to handle exhaust gas or charge air in medium-speed, 4-stroke engines. Kompressorenbau Bannewitz produces the HPR4000 model, which is specifically engineered for this demanding application. Service and maintenance for the HPR4000 should adhere to both the manufacturer's manual and the requirements of the relevant classification society. Annual inspections are recommended at class surveys. To ensure efficient operation and minimize downtime, it is crucial to stock spare parts as specified by the manufacturer. Common failures with this model include compressor fouling, turbine-side deposits, bearing wear, and oil leakage at the seal area. When ordering spare parts, such as service kits, bearings, and seals, always use the turbocharger's serial number for accurate identification.

Was unsere Servicearbeit und die Herstellerunterlagen zum Betrieb dieses Modells sagen.
Servicing per the manufacturer's manual and classification society requirements. Annual inspection at class survey. Stock spare parts as specified by the manufacturer.
| Daily/Weekly Checks | Visual inspection, oil level check (if applicable to system design) |
|---|---|
| 2,000 - 4,000 hours | Compressor washing (dry/wet), general external inspection |
| 4,000 - 8,000 hours | Turbine washing (wet), internal inspection of compressor/turbine side (if possible without major dismantling), bearing condition check |
| 8,000 - 16,000 hours | Major inspection, bearing replacement, rotor balancing check, cleaning of gas/air passages |
| 24,000 - 36,000 hours | Overhaul (complete dismantling, inspection, replacement of worn parts, balancing) |
| Bearing radial play | New: 0.15 - 0.30 mm; Wear limit: 0.40 - 0.50 mm (consult specific KBB manual) |
|---|---|
| Bearing axial play | New: 0.08 - 0.15 mm; Wear limit: 0.20 - 0.25 mm (consult specific KBB manual) |
| Blade tip clearance (compressor/turbine) | Manufacturer specific, typically <0.5mm increase from new value. |
| Rotor imbalance | Max allowable vibration velocity (e.g., ISO 10816-3 Group 2 for machinery on rigid foundations, typically <4.5 mm/s RMS for continuous operation). |
Die Bereiche sind für diese Bauklasse typisch. Maßgeblich sind stets die Herstellerunterlagen zur jeweiligen Seriennummer.
A class surveyor will typically review the turbocharger's maintenance records, running hours, and previous inspection reports. They will conduct an external visual inspection for oil/gas leaks, casing integrity, insulation condition, and overall cleanliness. Operational checks may include verifying boost pressure, exhaust temperatures, and observing for abnormal noise/vibration. The surveyor may also request bearing play measurements if there are concerns or if it's part of a scheduled major survey. Verification of safety devices, such as overspeed trip functionality (if applicable), is also a key point.
Geschätzte Lebensdauer: 24,000 - 36,000 hours before major overhaul (depending on operating conditions and maintenance adherence)
Service kits, bearings and seals should be ordered using the turbocharger serial number.
