Assigned Department Objectives
Teaching Method
Outline:
The aim is to develop a high-quality design drawing capability by understanding the principles of operation, structure, and performance calculations of a fluid machine, and by achieving harmonized coupling of each component, targeting pumps widely used in human society. The object of the design is a single-stage spiral pump with transverse shaft pull-in.
Style:
After explaining the design theory of the swirl pump in lectures, students will design the main components. Students will use CAD to create drawings of Front plan view primary based on the design.
Notice:
This course's content will amount to 180 hours of study in total. These hours include the learning time guaranteed in classes and the standard self-study time required for pre-study / review, and completing assignment reports. The first half of the first semester will involve lectures and explanation of the basic theory of pumps. Each student is then given a design specification to begin specific design calculations and drafting. Students should produce a calculation sheet, part drawing, or assembly drawing for use as a product to market level in a defined process.
Students who miss 1/4 or more of classes will not be eligible for evaluation.
