OIL AND WEAR PARTICLE ANLYSIS Abstract: Oil and wear particle analysis is a very powerful tool used to monitor and assess the health of a machine. Since the lubricant in a machine passes through all the internal parts that can wear‚ it is vital to maintain the quality of the lubricant thought oil analysis. Furthermore the presence of wear particles that are deposited in the oil can give a good indication of the wear material and the possible location of the abnormal wear

dissipation (iii) to increase the efficiency of the moving parts and (iv) to reduce damage of machine parts as seizure‚ surface deformation etc (v) to prevent the expansion of metal due to local frictional heat (vi) to minimize the possibility of corrosion‚ as the direct contact of metals is avoided by the formation of the lubricant film and (vii) to enhance smooth motion of the moving parts. Mechanism of lubrication Three important types / modes of lubrication are (i) thick film lubrication or hydrodynamic

COOLING TOWER INTRODUCTION: Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units
