Tanabe HC-85A 400/25bar

Tanabe Tanabe HC-85A 400/25bar is identified in the source list as a starting-air compressor. It is normally installed in the engine room and connected through cooling, separation and non-return arrangements to the vessel's starting-air receivers. Its purpose is to recharge compressed-air receivers used for starting main and auxiliary engines and for any approved associated pneumatic consumers. The existing database record states 25 bar. Marine starting-air compressors are commonly arranged as high-pressure reciprocating machines with staged compression and intercooling, although the exact construction of this model must be confirmed from manufacturer data. The exact series and model designation distinguishes compressor size, speed and arrangement from neighboring variants; delivery and operating limits must be taken from the manufacturer documentation.

Common failures & inspection points

●Suction or discharge valve leakage caused by carbon deposits, damaged valve plates or wear, resulting in reduced capacity, high stage temperatures or abnormal pulsation
●Piston-ring or cylinder wear caused by inadequate lubrication, contamination or long service, resulting in reduced compression, oil carry-over or extended filling time
●Intercooler or aftercooler fouling and leakage caused by scale, corrosion or poor cooling-water flow, resulting in elevated air temperature or water leakage
●Lubrication failure caused by low oil level, blocked passages or pump problems, resulting in abnormal bearing noise, temperature rise or seizure risk
●Automatic unloading, drain or non-return valve malfunction caused by sticking, contamination or control faults, resulting in difficult starting, pressure backflow or abnormal cycling

Service & Maintenance

Check oil level and condition, cooling-water flow, stage temperatures, valve operation, drains, separators, relief devices and non-return arrangements. Listen for abnormal knocking and compare receiver filling performance with the vessel's established normal condition. Inspect for air, oil and cooling-water leakage and confirm that automatic condensate drains are functioning. Examine drive belts or coupling components where fitted and verify guards are secure. During overhaul, inspect valves, piston rings, cylinders, bearings and coolers for deposits and wear. Refer to the manufacturer documentation for the exact pressures, clearances, valve settings and overhaul criteria.

Replacement Parts

Keep suction and discharge valve service parts, piston rings, gaskets, seals, filter elements, lubrication consumables and drain or unloader service parts recommended for the installed compressor. Critical vessels commonly require enough parts to restore one compressor after a typical valve or sealing failure. Confirm exact parts against the model and serial number.
