摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a diffuser capable of acquiring a required curvature shape at a front edge of a vane easily and with high accuracy by forming an arc-shaped rounded part in which the radiuses of curvature differ in various ways, at a corner part of a groove easily and with high accuracy.SOLUTION: A manufacturing method of a diffuser includes: a wall creation step of preparing a front wall member (9) and a rear wall member (10) facing in an axial direction of a diffuser (8) of a centrifugal compressor; a groove forming step of forming a plurality of grooves (13) extending from an inner periphery to the outer periphery in a radial direction arranged in parallel in the peripheral direction at a rear face of the front wall member and at a front face of the rear wall member; and a bonding step of forming a diffuser passage (20) between vanes by the groove by bonding the front wall member and the rear wall member by vanes (18,19) between the grooves. In the groove forming step, the front edges of the vanes (18,19) forming an acute angle are curved so that a central part in a span direction recesses toward the downstream by forming arc-shaped rounded parts (22,23) by a ball end mill (29) at the corner part of the groove.

摘要： PROBLEM TO BE SOLVED: To achieve a sufficient cooling of a scroll and moreover, a reduction in pressure loss. SOLUTION: A flow straightening means such as flow straightening body 1 is provided at an outlet D1 of a diffuser D to remove a spiral component applied by a compressor from air for combustion while a flow straightening cover is arranged to cover the outer circumferences of the rear and inside of a scroll S and at a specified interval. Thus, after the removal of spiral components applied by the compressor at the outlet D1 of the diffuser, the air for combustion is supplied to a gas turbine combustion device C along the outer circumference of the scroll S at a flow velocity enough to allow the cooling of the scroll S.

摘要： PURPOSE: To manufacture a diffuser very simply while providing a desired shape flow path or passage by joining wall surface members formed with a plurality of desired shape groove parts to constitute the diffuser having the flow path or passage. CONSTITUTION: First and second wall surface members 1, 2 are formed respectively with first and second groove parts 12, 22 providing a flow path or passage 3 of a diffuser by cutting or grinding so that the diffuser having a desired shape flow path or passage 3 can be manufactured by a simple operation of joining both parts with a bolt. Thus, since the diffuser having the optimum flow path or passage shape is provided, the dynamic pressure formed by an impeller can be converted to the static pressure with high efficiency to provide an excellent effect of improving the adiabatic efficiency of a compressor. Also, the restriction of working in the design of the flow path or passage is not needed to be considered.
