Blockbaserad provning

Sammanfattning

Alfa Laval’s strategy is to focus on modularized product platforms. Several benefits are

foreseen, reduced lead-time, less costs, shorter Time To Market and better quality.

Development and verifying will be carried out on block level. Today the separators are

being tested as a complete unit. A number of factors affect the test results and problems

that are encountered can be hard to identify. In production, problems often result in

delayed delivery.

The objective with this study is to develop a test rig that fulfills the demand for separate

testability of hermetic outlet modules.

To define problems with the existing test methods a study to analyze the needs and

applicable test methods has been executed. The study shows that there is a need of a test

rig, particularly for the development process. Separate assembling of the outlet should be

accomplished before implementing the separate testability in the manufacturing process,

so the outlet can be verified and assembled individually before final assembly of the

separator.

The thesis presents a number of conceptual solutions for separate testability of the outlet

module. One of them, based on the machine bottom part, is considered to be the most

appropriate due to best satisfaction of the specification.

The advantages with separate testing of the outlet module are increased safety, more

rapid and earlier testing in the development process, less costs, superior repeatability and

a refined test result.

The Master Thesis recommends further development of a test rig for the outlet module as

a part of Alfa Laval’s modularization strategy, and to make use of the benefits that

separate testability convey.
