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.
