Reliability and energy efficiency analysis of a two pass shell and tube heat exchanger in a hydraulic driven system

The Shell-and-Tube Heat Exchangers (STHEs) are typically used for high pressure applications and are perhaps the most common types of heat exchangers that are used in industrial applications. Performance of the STHEs effect the productivity and process cost of a system. Also, industrial hydraulic driven systems need to use of exchangers for stabilizing the hydraulic oil temperature in the acceptable intervals. In this study, two pass STHE of an Injection Molding Machine (IMM) is taken in the consideration for Failure Mode and Effect Analysis (FMEA). According to the FMEA results, high risk fouling failure effect of the heat exchanger is analyzed dealing with the roles on the reliability and energy efficiency of the system. In the end of the analysis, Reliability Centered Maintenance (RCM) tasks are recommended due to minimize the fouling failure effect of the STHE. © Sila Science.
