Vibrational Analysis and Optimization of a Water Injection Pipeline in a High-pressure Plunger Pump
The vibration of water injection pipeline systems in oilfields creates challenges in terms of safe long-term operation. To fully understand the vibration mechanism of plunger-powered high-pressure water injection pipelines, we conducted fluid pressure pulsation calculations and fluid structure coupling modal evaluations using finite element analysis software to study the effects of pressure, pipe length, and pipe clamp on the vibrations. The results indicate that the total displacement increases with increasing pressure, although the magnitude of the increment gradually decreases. The pipe length has a significant impact on the natural frequency. Based on the findings of the present study, we proposed that pipe clamps could be introduced to reduce the vibrations in an existing high-pressure plunger pump water injection pipeline, and the overall design was optimized. Comparative modal analysis revealed the most practical number and position of the pipe clamps to be suitable for a pressure range of 42–70 MPa.
期刊介绍:
The Journal of Applied Fluid Mechanics (JAFM) is an international, peer-reviewed journal which covers a wide range of theoretical, numerical and experimental aspects in fluid mechanics. The emphasis is on the applications in different engineering fields rather than on pure mathematical or physical aspects in fluid mechanics. Although many high quality journals pertaining to different aspects of fluid mechanics presently exist, research in the field is rapidly escalating. The motivation for this new fluid mechanics journal is driven by the following points: (1) there is a need to have an e-journal accessible to all fluid mechanics researchers, (2) scientists from third- world countries need a venue that does not incur publication costs, (3) quality papers deserve rapid and fast publication through an efficient peer review process, and (4) an outlet is needed for rapid dissemination of fluid mechanics conferences held in Asian countries. Pertaining to this latter point, there presently exist some excellent conferences devoted to the promotion of fluid mechanics in the region such as the Asian Congress of Fluid Mechanics which began in 1980 and nominally takes place in one of the Asian countries every two years. We hope that the proposed journal provides and additional impetus for promoting applied fluids research and associated activities in this continent. The journal is under the umbrella of the Physics Society of Iran with the collaboration of Isfahan University of Technology (IUT) .
