Abstract

The embodiments of the present invention discloses a system and method for providing an intrinsic safety to rotating machinery from the failure of internal high speed rotating structures. According to an embodiment, a system assembly comprises a unique design of the rotating structure to provide a sufficient safety margin and redundancy in configuration. The system assembly comprises a blower fan assembled inside a blower casing and rotated inside the casing. The fan is manufactured by a single forging process instead of an investment casting. The fan comprises several blades mounted to a hub in a shroud to draw a required quantity of fluid. The fan is mounted to a shaft through the hub. When the blower fan is rotated at a high speed exceeding the design parameters, a 'rub and stop' mechanism is initiated to halt the fan.
