Vacuum collapse
Vacuum Collapse
A vacuum collapse refers to the sudden and uncontrolled implosion of a created vacuum within the suction line of a fire pump. This phenomenon occurs when the vacuum becomes too strong and atmospheric pressure overwhelms the system. As a result, the pump may no longer be able to draw water from a source, jeopardizing the water supply during operations.
Causes and Effects
The main causes of a vacuum collapse include insufficient ventilation of the suction line or overly tight sealing of the system. This leads to excessive negative pressure, which can
