Inspector Detail

▸

Common issues

Crankcase oil carry-over from poor oil separation causing low oil pressure trips
Suction/discharge valve plate wear leading to reduced capacity and elevated discharge temperature
Shaft seal leakage causing slow refrigerant and oil loss
Capacity control mechanism (slide valve or cylinder unloader) sticking
High discharge temperature from low suction superheat setting or leaking valves
Vibration or knocking from worn connecting rod bearings or piston rings
Refrigerant leakage at gaskets/glands - safety-critical if the system uses ammonia

Inspection checklist

Check crankcase oil level and condition; sample for moisture/acid content on ammonia systems
Inspect suction/discharge valve plates for wear or pitting at overhaul
Measure discharge temperature and compare against the safe operating limit
Check shaft seal for leakage or weeping
Test low/high pressure and low oil pressure safety cutouts
Inspect capacity control mechanism for correct, smooth operation
Check vibration levels and foundation/mounting bolt tightness
Verify refrigerant charge and leak-test with an approved detector

Service intervals

Oil change	commonly every 2,000-4,000 running hours or annually, whichever comes first - confirm against GEA's maker manual
Oil filter replacement	commonly every 500-1,000 running hours
Safety cutout (pressure/oil) function test	annually, as part of periodical survey
Valve plate inspection	at major overhaul, commonly in the 8,000-12,000 hour range but strongly duty-dependent

Typical wear limits

Shaft seal leakage	should stay within the maker's specified drip/weep allowance; continuous leakage is not acceptable - confirm the exact figure against GEA's manual
Valve plate condition	renew when sealing surfaces show visible pitting or when capacity loss exceeds roughly 10% of rated output - confirm against GEA's overhaul criteria rather than a fixed clearance number, which is not confidently known for this specific series

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

Suction/discharge valve plate set
Shaft seal kit
Piston rings
Oil filter elements
Cylinder head/valve plate gasket set
Refrigerant-side safety relief valve

Safety

If the system uses ammonia (NH3): toxic and flammable gas - work in a ventilated space, keep breathing apparatus available, no naked flames nearby
High-pressure refrigerant release risk during valve plate or gasket work - fully isolate and depressurise first
Hot surfaces at the compressor head and discharge line
Confirm gas-free/ventilated status before entering an enclosed machinery space after any suspected leak

Class survey

Where the refrigeration plant serves an essential service (reefer cargo, crew provisions), the compressor typically falls within Continuous Survey Machinery scope. Class wants safety cutout test records, and - on ammonia systems - a gas detection log and evidence of periodic oil/refrigerant condition checks.

Estimated lifetime: Reciprocating industrial/marine refrigeration compressors of this size typically reach 60,000-100,000 running hours before a major crankcase/block overhaul, strongly dependent on duty cycle and refrigerant type - confirm against GEA's design documentation for the Grasso V 1100 series.
