Abstract
Reliability of a product is determined by the reliability tasks performed during the product design. Therefore, a method called Design for Reliability (DFR) which commonly used during the product design stage comes in handy to increase reliability. The purpose of this project is to examine a mechanical seal given from the reverse engineering perspective. Tools used to assist in DFR are Failure Modes and Effects Analysis (FMEA) and Fishbone Diagram. Every component in mechanical seal is analyzed. The component will be examined thoroughly using FMEA table where potential failures are identified and solutions will be generated. Three parameters taking into considerations are the severity, occurrence and detection which determine the Risk Priority Number. From the data obtained from various sources on the mechanical seal, a critical area is identified by the highest Risk Priority Number in FMEA table. The critical area identified to be the seal faces in between the front seal and rear seal of the mechanical seal. The solutions generated will give an idea of what improvement should be made at the seal faces. One of the solutions is to select a material which can withstand a higher temperature than the design temperature.
