Extend equipment life. Ensure lubricant suitability for continued use. Monitor viscosity levels for optimum performance. Reduce unscheduled downtime. Increase reliability. Boost company profit. LUBRICANT OIL ANALYSIS : LUBRICANT OIL ANALYSIS Moisture. Mechanical Impurities. Density. Viscosity. Acidity. ASTM D 4378-97 is Standard Practice for In-Service Monitoring of Mineral Turbine Oils for Steam and Gas Turbines. LUB OIL DIAGNOSIS : LUB OIL DIAGNOSIS Degradation of lubricant oil. Impurities in lubricant oil. Wear debris in lubricant oil. Wear Debris Analysis : Wear Debris Analysis The continuous trending of wear rate monitors the performance of machine /machine components and provide early warning and diagnosis. Oil condition monitoring can sense danger earlier than vibration technique. Oil Cleanliness Coding ISO 4406 (1999) : Oil Cleanliness Coding ISO 4406 (1999) CATEGORIES OF WEAR PARTICLES TYPES : CATEGORIES OF WEAR PARTICLES TYPES Normal rubbing wear Cutting wear Bearing wear Severe sliding wear Nonferrous wear particles Corrosives wear Spheres Black oxides contaminants NORMAL RUBBING WEAR : NORMAL RUBBING WEAR Typically ferrous string particles Size less than 10 microns Aligned along to magnetic field The greater the size ,greater the severity CUTTING WEAR : CUTTING WEAR 2 body wear (metal/metal) softer metal is cut. 3 body wear (metal/contaminant/metal) harder metal is cut curls of metal like lathe swarf 5 μm to 5000 μm in size (10-85 μm usual) bad machining, contaminants, misalignment BEARING WEAR : BEARING WEAR Laminar bearing wear particles are flat Caused by high load Usually more than 20 microns NONFERROUS WEAR PARTICLES : NONFERROUS WEAR PARTICLES Copper alloys are yellow Aluminum alloys are white Lead/tin Babbitt is purple when heated OXIDES : OXIDES Red oxides -Orange/red particles indicating water in oil. Black oxides-black particles aligned in ferrous strings caused by high temperatures at contact points CONTAMINANTS : CONTAMINANTS Sand /dust particles Fibers which are long straight or curly transparent particles cause by filter deterioration CORROSIVE WEAR : CORROSIVE WEAR Small particles less than 1 micron Caused by acidic attack on internal surfaces SPHERES : SPHERES Friction melting of other wear particles Small ball-bearing like spheres 5 μm to 30 μm in size (5 - 15 μm usual) Only during periods of extreme friction LUBRICANT OIL THERMAL POWER PLANT : LUBRICANT OIL THERMAL POWER PLANT TURBINE BEARING LUB OIL BOILER FEED PUMP TURBINE LUB OIL Mill gear box. FAN BEARING LUB OIL PUMP LUB OIL OIL ANALYSIS REPORT:MILL GEAR BOX-(wear elements in ppm) : OIL ANALYSIS REPORT:MILL GEAR BOX-(wear elements in ppm) fe -1334 Cr-11 Ni-28 Cu-1755 Sn-178 Zn-37 Al-44 Si-140 Mn-19 misalignment gear assembly WEAR DEBRIS ANALYSIS & DIAGNOSIS : WEAR DEBRIS ANALYSIS & DIAGNOSIS This monitors equipment condition and can identify types and possible sources of wear and contamination. It includes a Particle Count or Ferrography A Particle Count identify all particles present measuring 4 to 100 microns in size.
