Definitions

  • the invention relates to a motor vehicle foam extinguishing unit with a water tank, a motor-driven water pump and a pressure outlet as a hose or pipe, and with a foam agent tank, a foam agent pump and a mixer for the pressure outlet.
  • the object of the invention is to provide a motor vehicle foam extinguishing unit of the type mentioned, which not only avoids the additional control effort required by the foam agent pump according to the prior art, but is also very compact, can be manufactured at low cost and can be operated reliably.
  • the subject of the invention is further developed by the features of subclaims 2 to 6.
  • the essence of the invention is to arrange the water pump and foam pump on a single shaft or on a shaft train which is driven by the drive motor which is already provided in the motor vehicle.
  • the foam agent pump is designed for a higher pump pressure than the water pump. In particular, it emits an approximately four bar higher pressure than the water pump. It is preferably equipped with a peripheral rotor.
  • a known admixing regulator can be used as the admixer. Alternatively, however, the admixer has an electronic control device with corresponding sensors and control valves.
  • the problem is therefore solved by driving the foam pump and the fire-fighting centrifugal pump in a tandem design by the vehicle engine.
  • the foam compound pump can be accommodated anywhere in the drive shaft to the water pump or directly in a compact design on the water pump. If the machine operator regulates the delivery rate of the water pump up or down, the foam medium pressure also increases or decreases with the change in speed parallel to the water pressure.
  • a foam extinguishing unit (1) of a motor vehicle in particular a fire engine, comprises a water tank (2), a downstream water pump (4), the suction pipe connection of which is connected to the water tank (2).
  • the pressure connection of the water pump (4) leads via a spray hose or a spray pipe (5) to the point of use, with an admixer (8) being interposed.
  • the foam extinguishing unit (1) further comprises a foam agent pump (7), the suction connection of which is connected to a foam agent container (6) and the pressure connection of which is connected to the admixer (8) is to mix foam agent into the water in a suitable controlled manner so that a foam is formed which is ultimately sprayed to extinguish a fire or the like.
  • the water pump (4) and foam compound pump (7) are driven by the same motor (3) that is the drive motor of the motor vehicle.
  • Water pump (4) and foam agent pump (7) run according to the embodiment of FIG. 2 spaced apart on a shaft (10) or on a short shaft (9) according to FIG. 3 in a compact design.
  • the shaft train (10) and shaft (9) are connected to the output side of the motor (3) via a cardan shaft.
  • the foam agent container (6) is integrated with the water container (2).
  • the position of the foam compound container (6) in the water container (2) is determined by the position of the foam compound pump (7) in the drive train.
  • the position of the foam agent container (6) is selected so that there is a short foam agent piping to the suction side of the foam agent pump (7).
  • the foam agent pump (7) is designed according to FIGS. 4 and 5 with a so-called peripheral rotor (11).
  • FIG. 6 The basic sketch of a motor vehicle foam extinguishing unit according to the prior art is shown in FIG. 6.
  • the foam extinguishing unit (1) according to the invention according to FIG. 1 in the prior art there is an additional pressure meter (12) on the pressure side of the water pump upstream of the admixer (8) and another pressure meter (13) on the pressure side of the foam agent pump (7) .
  • Both pressures are compared in the controller (14) and the pressure of the pressure gauge (13) is adjusted by a motor (15) which separately drives the foam agent pump (7) in such a way that the foam agent pressure delivered is greater than the water pump pressure.
  • the units (12, 13, 14, 15) and drive shaft (16) between the motor (15) and foam pump (7) which are provided according to the prior art, are omitted in the invention.
