Abstract

The invention relates to a squirrel cage deformation test device and method, and aims to solve the problems that a conventional press cannot provide a load applied to an inner hole of a squirrel cage support and cannot meet test conditions. The squirrel cage deformation test device comprises an upper pressing ring, an ejector rod, a lower pressing ring, a support beam and a lifting bolt, one side of the squirrel cage support is connected with a bent plate through a lengthened flange. The upper pressing ring and the lower pressing ring are sequentially installed on the other side of the mouse cage support from top to bottom, the lower end of the upper pressing ring is connected with the upper end of the lower pressing ring through the ejector rod, the upper end of the supporting beam is connected with the lower pressing ring, and the lower end of the supporting beam is connected with the electric ring through a screw. The invention belongs to the technical field of heavy duty gas turbines. By using the test device and method, the applied load can be controlled at the center of the inner hole required to be measured by the mouse cage, and the load is uniformly distributed within 70% of the area of the supporting inner hole.

Description

technical field [0001] The invention relates to a deformation test device, in particular to a squirrel cage deformation test device and method, and belongs to the technical field of heavy-duty gas turbines. Background technique [0002] For the squirrel cage support of the second half of the compressor of the company's reflashing project, this part is the main support bearing of the rotor of the second half of the compressor. It is necessary to simulate the deformation under a certain load according to the force under the working state. Therefore, the drawings require that the rated load be applied to the inner hole at one end of the support to conduct a deformation test to test the displacement of the axis. In addition, the applied load is required to be more than 70% of the overall bonding area of ​​the supporting inner hole, that is, the load is required to be evenly distributed within 70% of the inner hole area. The direction of force is also in the center of the inner ...
