For Models: JGH:E:K:T Section 6 - Troubleshooting Minor problems during routine operation of an Ariel compressor most often trace to liquid, dirt, improper adjustment, or operators unfamiliar with Ariel compressors. These difficulties can usually be corrected by cleaning, proper adjustment, elimination of an adverse condition, part replacement, or proper training. Major problems usually trace to long periods of operation with unsuitable lubrication, careless operation, lack of routine maintenance, or using the compressor for purposes not intended. Recording interstage pressures and temperatures on multistage units is valuable. Any variation when operating at a given load point indicates trouble in one of the stages. Normally, a decrease in interstage pressure indicates trouble in the lower pressure cylinder. An increase usually indicates trouble in the higher pressure cylinder. Below is a list of common problems and possible causes. Problem Possible Causes Low Oil Pressure High/Low Suction Pressure High/Low Inter-Stage Pressure Noise in Cylinder Frame Knocks • Oil pump pressure regulating valve set too low or sticking. • Oil pump or oil pump drive failure. • Oil foaming from counterweights striking oil surface (oil level in sight glass too high), or from vortex at strainer inlet (oil level in sight glass too low), or from leaks in pump suction line. • Cold oil. • Dirty oil filter. • Interior frame oil leaks. • Excessive leakage at bearings. • Improper low oil pressure switch setting. • Oil pump relief valve set too low. • Defective pressure gauge. • Plugged oil sump strainer. • Improper end clearance in oil pump. • Suction control valve malfunction. • Faulty pressure gauges. • Frozen/plugged inlet line. • Plugged intake screen or filter. • Scrubber dump valve stuck open. • Recycle malfunction. • Site production equipment problems. • Faulty valves or rings. • Gas leak. • Frozen cooler section or tubing to panel. • Faulty pressure gauges. • Scrubber dump valve stuck open. • Load change. • Loose piston. • Piston hitting cylinder head end head or crank end head. • Loose crosshead balance nut. • Broken or leaking valve(s). • Worn or broken piston rings or wear bands. • Valve improperly seated or damaged seat gasket. • Liquids in cylinder. • Loose crosshead pin or pin caps. • Loose or worn main, crankpin, or crosshead bearings. • Low oil pressure. • Cold oil. • Incorrect oil. • Knock is actually from cylinder end. • Low fluid level in damper. 3/11 PAGE 6-1
