Benefits of technology

[0029]According to one embodiment herein, the rub and stop mechanism is devised based on frictional contact between a high speed rotating part and an enclosure of the rotating part. The frictional contact gradually reduces the speed of the rotating part and brings the rotating part to a halt thereby providing an intrinsic safety to the rotating mach

Problems solved by technology

In case the speed of the rotating component exceeds a certain critical value termed as the burst speed, the rotating structure fails catastrophically due to the stresses.
This leads to heavy and bulk

Embodiment Construction

[0008]The primary object of the embodiments herein relate to a system and method for providing an intrinsic safety to the rotating machines against the failure of high speed rotating structures.

[0009]Another object of the embodiments herein is to provide a method and system for preventing failure of rotating structures.

[0010]These and other objects and advantages of the embodiments herein will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

SUMMARY

[0011]The various embodiments of the embodiments herein provide a system and method for providing an intrinsic safety to a rotating machinery from the failure of internal high speed rotating structures. The intrinsic safety system for a rotating machine comprises a blower fan which is a rotating structure and a blower casing for holding the blower fan. The blower fan is rotated under the influence of pressure from an incoming fluid. The blower fan further comprises a plura...

Abstract

The embodiments herein disclose a system and method for providing an intrinsic safety to rotating machinery from the failure of internal high speed rotating structures. According to one embodiment herein, 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.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This patent application claims the priority of the Indian Provisional Patent Application No. 3755 / CHE / 2013 filed on Aug. 26, 2013, and postdated to Nov. 26, 2013 with the title “A System and Method of Implementing Intrinsic Safety in Rotating Structures”, and the content of which is incorporated in entirety by reference herein.BACKGROUND[0002]1. Technical Field[0003]The embodiments herein generally relate to rotating machinery and particularly relates to a method for protecting the rotating structures from failures at high speed rotations. The embodiments herein more particularly relates to a system and method for providing an intrinsic safety to the rotating structures of the turbo machines against failure, more specifically disk burst.[0004]2. Description of the Related Art[0005]Rotating structures are subject to the centrifugal forces which cause stresses. These stresses tend to exist in the radial and tangential directions of the rota...
