Project on Pumps
INTRODUCTION
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
