When the machine fails or break down, the consequences can range from annoyance to financial distortion, personal injuries and possibly the loss of life. For this reason, the early detection, identification and correction of machine problems paramount to anyone involved in the maintenance of industrial machinery to ensure continuous, safe productive operation. The use of machinery vibration and the technology advances that have been developed over the years make it possible to not only detect when a machine is developing a problem but to identify the specific nature of the problem for scheduled correction. In addition, human perception of touch and feel is somewhat limited and there are many common problems such as bearing and gear failure that are generally put out of the range of human perception. Thus vibration analysis of rotating machine not only minimises the need for extensive expenses but make it possible to detect developing problems which are out of the range of human sense of touch and feel. We introduce the beginning of vibration analysis and develop a simple, logical and systematic approach that has been proven successful in pinpointing the vast majority of the most common machinery problem. We intend to do a project on “Vibration analysis of centrifugal pump at BPCL Kochi Refinery”. The vibration analysis we have done is a part of predictive maintenance on rotary equipments. This technique is mainly used for the improved performance of equipments. Using this we can predict the condition of internal parts of the equipment. We are mainly dealing with the vibration analysis of centrifugal pump, compressors and motors. It includes typical causes of vibration like misalignment of shaft, looseness, bearing faults, unbalance, oil failure etc. This project explains the vibration analysis on pumps and motors of BPCL Kochi Refinery, the methodology, readings, analysis and the performance of vibration analysers through case study. All cases and efforts are taken during the project at an industry like BPCL Kochi Refinery which is round the year operating organisation dealing with highly inflammable as well as prime products of petroleum.
Vibrational Analysis of Centrifugal Pumps
Bharat Petroleum Corporation Limited-Kochi Refinery An Overview Kochi Refinery, a unit of Bharat Petroleum Corporation Limited, embarked on its journey in 1966 with a capacity of 50,000 barrels per day. Formerly known as Cochin Refineries Limited and renamed as Kochi Refineries Limited, the refinery was originally established in collaboration with Phillips Petroleum Corporation, USA. Today it is a frontline entity as the unit of the Fortune 500 Company, BPCL. Kochi Refinery, in Kochi, Kerala, is one of the two Refineries of BPCL, with a crude oil refining capacity of 7.5 Million Metric Tonnes per Annum (MMTPA). Now poised for enhancement to 9.5 MMTPA, the product portfolio of the refinery includes petrochemicals and specialty solvents in addition to its range of quality fuels. The Refinery has implemented world class technology and systems for operations and enterprise resource planning. It is an ISO 14001 Environmental Management Systems (EMS) and ISO 9001:2000 Quality Management System (QMS) accredited company and has also obtained the ISO 17025 (Testing Methods in Quality Control) certification from NABL (National Accreditation Board for testing & Calibration of Laboratories). With the prestigious Crude Oil receipt facilities consisting of the Single Point Mooring (SPM) and the associated shore tank farm in place since December 2007, the refinery is equipped to receive crude oil in Very Large Crude Carriers (VLCCs). This facility helps Kochi refinery in reducing the freight charges to a great extent, over and above increasing flexibility in crude oil selection. This, thereby, is a major infrastructure facility to accelerate the future growth of Kochi Refinery. So also the Capacity Expansion cum Modernisation...
