Experimental Investigation on Assembly Process for High Pressure Injection Pump Components

Abstract

Abstract The sealing gaskets are mechanical systems that seal and fill the gap between two or more jointed surfaces. The gasket have been created and designed to prevent leaks that can occur between surfaces subjected to compression and also, to prevent contamination with dust, mud or other impurities from outside of the system. The applicability area of these gaskets has increased visibly and they are currently used in a full range of equipment, such as mechanical transmissions, machines for terrain works, equipment production, etc. The way that seals help to fix and connect the mechanical assemblies, their stress resistance and their durability over the time have been studied by literature. The paper presents the influence of the components assembly in a high-pressure pump and its impact on sealing. Using the Taylor Hobson measurement system and scanning electron microscopy we were able to find out the composition of the gasket studied and determine the dimensional variations, mainly due to the assembly process.
