An installation tool for a compressor vane ring and a method for using the same

Abstract

The invention relates to a gas compressor fixed blade ring installation tool. A movable ring is arranged in an inner cavity of a first sleeve and an inner cavity of a second sleeve in an inserted mode; a separator plate is arranged in the first sleeve, and a through hole is formed in the separator plate; the inner wall of the second sleeve is provided with multiple grooves matched with a protrusion on a limiting section of the movable ring; the front section of the movable ring is further provided with a compressed spring in a sleeving mode. The invention further provides a usage method of the installation tool. The second sleeve is fixed on a gas compressor shell, a ring section of a fixed blade ring is installed in a ring groove of the gas compressor shell, an ejector pin is used for abutting the outer circumferential surface of the ring section of the fixed blade ring, the ring section of the fixed blade ring continues to slide along the ring groove, and when the end of the ejector pin is suddenly popped up, the alignment between a radial groove of the ring section of the fixed blade ring and a radial hole is finished. According to the gas compressor fixed blade ring installation tool and the usage method thereof, the radial groove in a slip ring of the fixed blade ring and the radial hole in the gas compressor shell can be precisely aligned, a locating pin can be smoothly inserted without needing secondary machining on the spot, and the installation of the ring section of the fixed blade ring with different depth can be completed by using the same tool.

Description

technical field [0001] The invention relates to the technical field of gas turbine manufacturing, in particular to a tool for installing a vane ring of a compressor and a method for using the same. Background technique [0002] A compressor is an impeller device that uses rotating mechanical energy to do work on the air flowing through it to increase the air pressure. A typical compressor for a gas turbine is generally multi-stage axial flow, each stage consists of a row of rotor blades and a row of stator blades, usually, the end of each stator blade of the row of stator blades is connected to a slip ring , forming an integral vane ring. Some known vane rings can be divided into several ring segments in the circumferential direction, and each ring segment is slipped into the circumferential groove of the compressor housing through the slip ring during installation. [0003] At present, in order to prevent the ring segment from moving circumferentially in the circumferenti...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide an installation tool for a compressor vane ring and its use method. When installing the vane ring, with the help of the tool, the radial grooves on the vane ring slip ring and the compressor The radial holes on the casing can be precisely aligned, and the positioning pin can be inserted smoothly without secondary processing on site, and the installation of the stator blade ring segments with different depths can be completed with the same tool, which solves the problem of low installation efficiency of the stator blade ring
