PUMP PRESSURE RELIEF SYSTEM

摘要

A pump features a casing assembly having a region through which high velocity fluid and solids circulate, a chamber where they do not, an aperture that allows a related-chamber to be in fluidic communication with the region, but not the circulating high velocity fluid and solids, and a corresponding aperture to allow the related-chamber to communicate with an external region outside the casing assembly; and a rupture disc received in the corresponding aperture to close the related-chamber subjects the related-chamber and the rupture disc to pressure contained within the region and to release pressure exceeding a predetermined relief pressure of the rupture disc from the related-chamber to the external region or location, and exhaust piping couple the rupture disc to provide a path for escaping vapor and solids to be directed to the external region or location where the energy can be dissipated.

主权项

1. Apparatus, including a pump or rotary equipment, comprising:
a casing assembly configured with an inner casing to form a region through which high velocity fluid and solids circulate, configured with an outer casing to form a chamber between the inner casing and the outer casing that does not have circulating therein the high velocity fluid and solids, and also configured with a seal cover arranged between the inner casing and the outer casing, the inner casing being configured with an aperture that, together with the seal cover, creates a related-chamber that is in fluidic communication with the region of the inner casing through which high velocity fluid and solids circulate, but also does not have circulating therein the high velocity fluid and solids, the seal cover being configured to form a corresponding aperture to allow the related-chamber to be in fluidic communication with an external region or location outside the casing assembly; and a pressure relief system comprising: a rupture disc assembly having a rupture disc configured to be received in the corresponding aperture of the seal cover and to close the related-chamber so communication of the related-chamber with the region subjects the related-chamber and the rupture disc to at least a portion of pressure contained within the inner casing, and also configured to release pressure exceeding a predetermined relief pressure of the rupture disc from the related-chamber to the external region or location, and an exhaust piping arrangement having exhaust piping configured to attach to the casing assembly, couple the rupture disc assembly in the corresponding aperture of the seal cover, and provide from the related-chamber a path for escaping vapor and solids to be directed to the external region or location where the energy can be dissipated.
