Pressurized dual fluid jet system

摘要

A dual capability ultra high pressure (UHP) fire attack system includes a fluid jet assembly and an UHP attack line system. The fluid jet assembly and the UHP attack line system are coupled to a high pressure fluid source. The fluid is discharged from both the fluid jet assembly and the UHP attack line system as a mist having a droplet diameter of approximately 150 microns. When infused with an abrasive material, the fluid jet assembly may be used to cut through structural surfaces, so that a fire may be “knocked down” before the fuel source is attacked.

主权项

1. A pressurized dual output base station comprising:
a base station including a pump that is configured and arranged to discharge a pressurized fluid; a first output fluidly coupled to an ultra high pressure attack line system and configured and arranged to dispense the pressurized fluid from the base station through the fluid jet assembly; a multi-valve junction sub-system that is configured and arranged to entrain an additive into the pressurized fluid to form an additive entrained pressurized fluid; a second output fluidly coupled to a fluid jet assembly that is separate from the ultra high pressure attack line system, and is configured and arranged to dispense the additive-entrained pressurized fluid from the base station through the fluid jet assembly separate from the pressurized fluid without the entrained additive from the ultra high pressure attack line system; and a selector fluidly coupling the pump to the first output in a first position and fluidly coupling the pump to the multi-valve junction sub-system in a second position; the selector configured to select between the additive-entrained pressurized fluid and pressurized fluid without the entrained additive.
