Obviously, when fire-fighting foams sprayed in system, the delivery port of water pump 3 can have three paths to work simultaneously.Wherein, article one at first with behind the foam solution pipeline P8 interflow enters foam and all mixes pipe 7, with after compressed air the mixings prefoam towards water cannon; Second enters air compressor machine cooling water pipe 61, and press water enters air compressor chillers from exit of pump, gives the cooling of air compressor machine lubricating oil; Article three, the adjusting by second valve 10 by the road P6 be back to water pot 1, regulate the engine speed rotating speed coupling required by valve opening with air compressor, simultaneously, water pump generates heat in the time of can avoiding water cannon to close by refluxing.
In order accurately to control the accurate proportion relation between foam solution and the water, present embodiment is utilized the flow of flow FEEDBACK CONTROL foam solution, mixes with the ratio of water thereby accurately control foam solution.Particularly, first flow meter 13 is arranged at water pump 3 and foam pump 4 to foam all mixes on the pipeline P7 that manages between 7, the liquid outlet of first flow meter 13 is communicated with the import that foam all mixes pipe 7, its inlet is communicated with the liquid outlet of water pump 3 and foam pump 4 respectively, so that detect the flow of water and foam mixing liquid; Second flowmeter 14 is arranged on the fluid pipeline P8 of foam pump 4, so that detect the flow of foam solution.During actual design, the foam solution flow signal that the mixed liquor flow that first flow meter 13 detects and second flowmeter 14 detect inputs to controller, controller is promptly controlled the flow of foam solution, thereby is made foam solution and water form accurate proportioning according to the running of programming instruction control motor.As shown in the figure, the pipeline P8 of second flowmeter, 14 upstreams is provided with the one way stop peturn valve of avoiding foam solution to reflux; And, be provided with safety valve at the liquid outlet place of foam pump 4, remain in certain scope with the operating pressure of guaranteeing foam solution pressure piping P8.
What specify is, above-mentioned feedback control principle belongs to a kind of conventional selection the in control technology field, and those skilled in the art can realize fully based on prior art, so this paper repeats no more.
In addition, on the pipeline P7 between described first flow meter 13 and all mixed pipe 7 of foam, also be provided with the 5th valve 15, to adjust the flow of fire-fighting foams, the operability of raising system according to the concrete condition of a fire.
The used in fire-fighting fire-fighting foams system that present embodiment provides not only can carry out compressed air foam extinguishing, can also select the water operation of putting out a fire.As shown in the figure, the liquid outlet of water pump 3 also passes through the feed liquor pipeline connection of pipeline P9 and each water cannon; And pipeline P9 is provided with the 7th valve 16 and check-valves.
Present embodiment also provides a kind of fire fighting truck that adopts foregoing fire-fighting foams system, sees also Fig. 2, the figure shows the overall structure schematic diagram of fire fighting truck.
This fire fighting truck comprises chassis 20, lifting arm support 30 and job platform 40, and job platform 40 is connected with chassis 20 by lifting arm support 30, also comprises foregoing used in fire-fighting fire-fighting foams system.During system matches, drive water pump 3 work by the total power power takeoff, the side window power takeoff drives the hydraulic pump works of hydraulic system, and the hydraulic pump drive hydraulic motor is again by 6 work of fluid motor-driven air compressor.What specify is, main function components such as the described chassis 20 of present embodiment, lifting arm support 30 and job platform 40 and prior art are identical, and this paper is not described in detail.
The concrete operations of this used in fire-fighting fire-fighting foams system of brief description below:
When one, selecting to fire-fight by water, open the 7th valve 16, the 8th valve 17, and connect water pump 3 power takings, can carry out sprinkling fire; When two, selecting to use compressed air foam extinguishing, open first valve 8, the 8th valve 17, and connection water pump 3 power takings, after treating the fire-fighting system pressure stability, open the 5th valve 15, regulate the foam ratio to OK range, open air compressor 6 then, regulate air mass flow and then regulate water cannon injection dry foam or wet foam by second valve 10, open the water cannon butterfly valve, carry out fire-fighting operation.In addition, can connect water band and hydraulic giant, carry out above operation again, promptly can open water outlet ball valve manipulation hydraulic giant and carry out fire-fighting operation from the water outlet interface 18 of second water cannon 52.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
