Description

9FB level gas turbine one-level double-ring metal temperature measurement point dismounting tool

The technical field is as follows:

the utility model relates to a 9FB level gas turbine one-level double ring metal temperature measurement station assembly and disassembly tools.

Background art:

with the application of heavy-duty gas turbines in China becoming more and more extensive in recent years, the requirement for the automatic maintenance of the gas turbine is also becoming higher and higher. Taking a domestic commonly-used model PG9371FB type gas turbine as an example, in the actual maintenance process, difficulty restricting normal implementation of the maintenance process can occur, and the conventional tools used at present can not realize normal removal of the measuring points. For example, a turbine cylinder body of a PG9371 FB-grade heavy-duty gas turbine is provided with 8 measuring points for measuring the temperature of a primary double ring, and the measuring points are connected with the cylinder body through special adapters. In the normal operation process of the gas turbine, the temperature of a turbine cylinder body can reach more than 300 ℃, the special joint is connected with the cylinder body through the tapered thread, although an anti-biting agent can be smeared before installation, the condition that the special joint cannot be detached from the cylinder body often occurs along with long-time operation of a unit, and the overhauling period and the replacement of a fault measuring point are influenced.

The invention content is as follows:

the utility model aims at providing a 9FB level gas turbine one-level compound ring metal temperature measurement station assembly and disassembly tools for demolish turbine one-level compound ring metal temperature measurement station. The invention can effectively solve the problem that the measuring point and the special joint can not be detached.

The above purpose is realized by the following technical scheme:

the utility model provides a 9FB level gas turbine one-level double ring metal temperature measurement station assembly and disassembly tools which constitutes and includes: the lower part of the cylindrical sleeve is welded and fixed with the sleeve, the centers of circles of the sleeve and the cylindrical sleeve are on the same vertical line, an inner hexagonal chamfer is formed above the cylindrical sleeve, the size of the inner hexagonal chamfer is 7/8 inches, the handle is vertically welded on the cylinder of the cylindrical sleeve, a rectangular opening is formed in the cylindrical sleeve, the top of the first-stage multi-ring metal temperature measuring point is inserted into the cylindrical sleeve, and a nut on the first-stage multi-ring metal temperature measuring point is arranged at the socket position of the inner hexagonal chamfer.

The disassembling tool for the first-stage multi-ring metal temperature measuring points of the 9 FB-stage gas turbine is characterized in that the cylindrical sleeve is inserted into the mounting position of the special joint on the turbine cylinder body, and the size of the handle is 2000 × 500 mm.

The utility model has the advantages that:

1. the utility model discloses wholly adopt the carbon steel foundry goods, the cylinder height is 200mm, external diameter 50mm, the sleeve is used for the lock of fixed one-level compound ring metal temperature measurement station female, can dismantle the compound ring metal temperature measurement station of one-level after fixed, interior hexagonal chamfer is used for the outer hexagonal joint interlock with the compound ring metal temperature measurement station of one-level, the inside cavity of cylinder cover sets up 7/8 inches interior side, cylinder cover part can be deepened in the special mounted position who connects on the turbine cylinder body, inside is the interior hexagonal chamfer of 7/8 inches, can be applicable to the compound ring metal temperature measurement station of one-level. The special tool is made of carbon steel, the special joint is made of 304 stainless steel, and operability is achieved. The special handle has the size of 2000 x 500 (length x width x height), has enough rigidity, and can be used as a knocking wrench after being tightly attached to the special joint.

2. The utility model has the characteristics of simple structure, convenient operation, with low costs, be convenient for production and processing etc, can be quick pull down the joint from the cylinder body, reduce the change of maintenance time limit for a project and trouble measurement station, improve work efficiency.
