The CFD Application in Analyzing The 024P108 Centrifugal Pump Damage as The Effect of High Vibration using Fluid Flow Discharge Capacity Parameters

Abstract

Petroleum is one of the natural resources that can produce energy both for fuel and for generating electricity. One of the most important and widely used equipment in this industry is a pump. A pump is a device for distributing fluids from one place to another. A centrifugal pump is a device for distributing move liquids from one place to another by converting the fluid's kinetic energy into potential energy through an impeller that rotates in the housing. The objective of this research is to analyze the damage of pump 024P108, which indicated high vibration due to using a high-speed shaft. The research is done by using an analytical method, using CFD Fluent analysis with flow discharge capacity under normal conditions and minimum flow conditions, and comparing the results by API 610. Afterward, the right maintenance will be known for the 024P108 centrifugal pump to reduce the high vibration that occurred in the pump. The pump is run at minimum flow with a flow rate of 22 m3/hr and the normal flow rate of the pump is 97.9 m3/hr so that the results show that the pump head has decreased to 198.74 m and the pressure drop has increased by 2.5995×105 Pa. The vibration test data shows that high vibration of 8.5 mm/s is produced by a minimum flow state of 22 m3/hr, this low fluid flow is the cause of high vibration on the pump. High vibration has an impact on pump performance, that is decreasing pump performance (efficiency) and if left continuously it can cause damage to the pump.

Energy, Exergy, Exergoeconomic, and Environmental (4E) Analysis of the Existing Gas Turbine Power Plants in BOB - PT. Bumi Siak Pusako Pertamina

“…The results showed that the highest system energy efficiency was in the gas turbine generator unit 2.3 with 35.541% and exergy efficiency was 34.069%. The gas turbine generator component with the lowest exergy efficiency was the combustion chamber unit 2.2 with 76.81% and an exergy destruction of 92.581 MW [9].…”

Investigation of Sloshing with Vertical and Horizontal Baffle in the Prismatic Tank using Meshfree CFD

“…Numerical methods for instance computational fluid dynamics (CFD) has widely used to solve free surface flow. CFD has been wide uses to solve free surface flow not only sloshing but also medical [1,2], marine engineering [3,4], mechanical engineering [5][6][7], Numerical study of floating breakwater was performed with CFD for calculation of transmission coefficient value [8]. Because free surface flow dealing with large discontinuities and deformation, meshfree CFD is suitable to apply.…”
