Abstract

Embodiments of the invention provide a fire-fighting system including a low-pressure system and an ultra-high pressure system (UHPS). The fire-fighting system can also include a foam proportioning system, which can inject a foamant into the low-pressure system and/or the UHPS. The low-pressure system and the UHPS can be simultaneously operated. Some embodiments of the fire-fighting system can be installed on aircraft rescue fire fighting (ARFF) vehicles.

Claims

1. A fire-fighting system comprising:

a water source;

a first pump drawing water from the water source at a first pressure; and

a second pump drawing water downstream of the first pump at a second pressure higher than the first pressure, the second pressure being at least about 500 PSI.

2. The fire-fighting system of claim 1, and further comprising at least a first discharge line and a second discharge line, the first discharge line connected to an outlet of the first pump and the second discharge line connected to an outlet of the at least second pump.

3. The fire-fighting system of claim 2, and further comprising a flow meter positioned along at least one of the first discharge line and the second discharge line.

4. The fire-fighting system of claim 2, wherein the first pressure is from about 150 PSI to about 400 PSI and the second pressure is from about 1200 PSI to about 1800 PSI.

5. The fire-fighting system of claim 1, and further comprising a control system.

6. The fire-fighting system of claim 5, and further comprising a foam proportioning system.

7. The fire-fighting system of claim 6, wherein the control system operates at least the foam proportioning system.

8. The fire-fighting system of claim 6, wherein the foam proportioning system includes a high-pressure foam pump.

9. The fire-fighting system of claim 8, wherein the foam pump is hydraulically driven.

10. The fire-fighting system of claim 1, and further comprising a cleaning agent system.

11. The fire-fighting system of claim 1, and further comprising a compressed air foam system.

12. A fire-fighting system comprising:

a water source;

a low-pressure system connected to the water source;

an ultra-high pressure system delivering water at a pressure of at least 500 PSI, the ultra-high pressure system connected to the low-pressure system; and

a foam proportioning system.

13. The fire-fighting system of claim 12, wherein the low-pressure system includes a first pump and the ultra-high pressure system includes at least a second pump.

14. The fire-fighting system of claim 12, wherein the foam proportioning system includes a foam tank and a high-pressure foam pump propelling a foamant from the foam tank into at least one of the low-pressure system and the ultra-high pressure system.

15. The fire-fighting system of claim 12, wherein the low-pressure system further includes an inductor capable of sucking a foamant from the foam proportioning system into the low-pressure system.

16. The fire-fighting system of claim 12, wherein the low-pressure system includes a first discharge line and the ultra-high pressure system includes a second discharge line.

17. The fire-fighting system of claim 16, and further comprising a flow meter positioned along at least one of the first discharge line and the second discharge line.

18. The fire-fighting system of claim 12, wherein a first pressure in the low-pressure system is from about 150 PSI to about 400 PSI and a second pressure in the ultra-high pressure system is from about 1200 PSI to about 1800 PSI.

19. The fire-fighting system of claim 12, and further comprising a control system.

20. The fire-fighting system of claim 19, wherein the control system operates at least the foam proportioning system.
