Title:
支持体、ポンプ及び支持体の固定方法
Document Type and Number:
Japanese Patent JP6824072
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To avoid fatigue breakdown at a welding portion, in a state where a resistance suppression effect against flow of fluid in a pump is kept.SOLUTION: A support body is configured to fix a component used in a pump to the pump with welding. An end surface around an end part of the support body formed into such a shape as to gradually spread in a width direction of the support body as approaching an edge of the end part. In the vicinity of a center of the end surface of the support body, a corner is chamfered or formed into a substantially concave curve shape. The end part of the support body is fixed with welding so that the end surface of the support body is a surface substantially orthogonal to a flow direction of fluid in the pump.SELECTED DRAWING: Figure 9
