Impact of particles in production of particle sensitive systems pre-study for new requirements for new components

It is well known that technical cleanliness in liquid systems in vehicles is important. However, it is not known what measures are required regarding particle occurrence in e.g. lubrication systems for engines with different types of bearings, hydraulic systems for construction machinery and gearboxes. In the project, the entire value chain for the manufacture of a product/component will be studied to identify in which operations particles (which, quantity and type) occur, the possibility to fix them and their effects. The long-term goal is to be able to put in place the right measures for the management of particulate matter for optimal product performance and avoid unnecessary measures that consume resources and create environmental impact. To remove unwanted particles, washes involving chemical, water and energy consumption are required. The preliminary study produces compilations to evaluate measures to keep particle occurrence down and opportunities to evaluate the effect of the remaining particles. A good summary of knowledge gaps and a good basis for development projects to address these shortcomings.
