PROGRAMME SUMMARY: -
Maintenance and troubleshooting of centrifugal pumps are important with reference to maintenance and operations. During this course, participants will have a clear understanding of the centrifugal pump theory and working principles.
Advances in modern technology have been dependent upon a rapid developing pump technology. Next to the electric motor, pumps are the most widely used machines in the world. There is hardly a single piece of major equipment that does not in some way depend upon pumps for its successful operation. Three classes of pumps find use today: centrifugal, rotary and reciprocating. These terms apply only to the mechanics of moving the liquid, not to the service for which the pump is designed. This course will cover the fundamentals of centrifugal, reciprocating and rotary pumps and compressors. Moreover, their operation, troubleshooting, maintenance, performance and fields of applications are thoroughly covered.
Understanding the design, operation & characteristics of High Pressure Pumps will have an important reflection on the process quality, equipment, plant reliability and the economics of the whole activity. Identifying the problems associated with these pumps is essential for diagnosis, troubleshooting and plan required maintenance.
This training course on High Pressure Pump Operation, Maintenance, Overhauling & Troubleshooting is designed to provide an in-depth perspective of High-Pressure pump technology in terms of selection, operation, maintenance and troubleshooting. This training course will also cover single stage and multi stages centrifugal pumps and positive-displacement pumps. Packing, mechanical seals, sealing systems, wear rings, coupling and alignment and other vital components will be explained in detail.
