| dc.description.abstract | A centrifugal pump’s hydraulic performance and reliability can differ drastically from its published performance expectations. The cause of the discrepancy may involve the hydraulic features of the pump. NPSH (net positive suction head) has received a lot of attention in most handbooks, but the trade-offs of NPSH against recirculation, piping design, system operation and mechanical features of the pump itself are not discussed in most instances. Some of the areas that have proven troublesome in pump operation are as follows:
1. Axial and radial hydraulic forces caused by recirculation effects
2. Hydraulic forces (Axial and radial) hydraulic forces caused by recirculation effects
3. Bearing system design as related to hydraulic loads
4. Hot oil pumps that suffer from thermal distortion and other installation problems.
5. Piping designs that cause vortexing and other disturbances
These subjects are discussed from the standpoint of maintenance experience at a large Gulf Coast refinery. | en |
