Description

Technical Field

[0001] The utility model belongs to the technical field related to gas turbines, and in particular relates to a gas turbine cover with a high safety factor. Background Art

[0002] The gas turbine cover is an important component of the gas turbine. It not only protects the internal parts, but also affects the performance of the gas turbine, including the noise level, temperature control, and ease of maintenance. When the gas turbine is working, the cover needs to effectively reduce the noise transmitted to the outside world and increase the safety level of the gas turbine during operation. However, it still has the following disadvantages in actual use:

[0003] When the gas turbine cover is working, the gas turbine is directly enclosed in the cover. After installation, when the gas turbine generates vibration during operation, the vibration is directly transmitted to the cover, and then to the supporting plane on the cover, affecting the support stability of the cover;

[0004] The gas turbine cover is in operation and the gas turbine is working inside it. When the gas turbine is working, heat will be transferred to the surface of the gas turbine, causing the temperature inside the cover to rise. When working, a small amount of gas in the gas turbine leaks into the environment, and the lack of air flow will create safety hazards. Utility Model Content

An air inlet 101 is opened in the center of both sides of the bottom cover shell 1. When the exhaust fan 301 exhausts air, the bottom cover shell 1 conveys external air to between the bottom cover shell 1 and the top cover shell 3 through the air inlet 101.

[0032] Furthermore, a base 401 is fixed to the bottom of the shock-absorbing pad 4 , and the top length and width of the base 401 are respectively equal to the length and width of the top of the shock-absorbing pad 4 . The shock-absorbing pad 4 and the bottom cover shell 1 are supported on the working plane through the base 401 .

[0033] The operating process of this embodiment is as follows: during operation, after the gas turbine is placed in the bottom cover 1, it is clamped by the inner sleeve 202 above the damping shock absorber 2, and the top cover 3 is inserted through the mounting bolts 303 on the second mounting bar 302, and then inserted into the mounting hole 103 on the first mounting bar 102, and then the fastening nut 304 is screwed onto the mounting bolt 303 and pressed against the first mounting bar 102, and then the bottom cover 1 and the top cover 3 are installed.
