Description
Technical Field
The utility model relates to the technical field of gas turbines, in particular to a coupling protection device of a gas turbine.
Background
The gas turbine coupling is a rotating member that couples the main engine, gearbox and generator to one another and is primarily used as a shaft-to-shaft connection that rotates during operation to transmit motion and torque. The coupling has a certain risk during high-speed operation, and in order to avoid danger caused by touching the high-speed rotating part, a fully-closed structure is generally adopted for the high-speed rotating turbine. Therefore, the coupler shield meets the requirements of better sealing, higher safety, convenient disassembly and assembly and the like.
The coupler protection device mainly plays a role in safety protection, at present, a plurality of coupler protection devices basically adopt a closed structure, but because the high-speed rotating coupler can frequently generate a blast effect in a closed space, lubricating oil in the coupler is thrown out, the oil flows into the shield, oil leakage is caused, and meanwhile, the thrown oil is thrown to the surface of the shield shell under the stirring of the high-speed rotating coupler, so that the surface of the shield shell is often overheated.
