Definitions

  • the invention relates to a mobile pump unit for Firefighting with a pump for sucking in Fire water from a water reservoir.
  • Fire-fighting vehicles When fighting fires, there are usually special ones Fire-fighting vehicles for use in which the Pumps required to pump and discharge the Extinguishing agent via appropriate pressure lines and Beam pipes are permanently installed on the fire truck.
  • Fire engines are inaccessible areas furthermore required on the fire engines mobile pump units that can be removed from the vehicle carry, which are set up at the location of the fire and by each with an available water reservoir can be supplied with an extinguishing agent.
  • the known, mobile pump units are common designed for water as an extinguishing agent.
  • Schmitz ONE SEVEN® system continues to be known in the fire fighting water with certain Mix in a foam concentrate that is essentially Foaming agent and agent for reducing the Surface tension of the water contains, bring in and depending on the amount of water, foaming agent and Air, the respective temperatures and pressures, the foam and other factors used Foam with according to the type of fire different properties and effects To provide fire fighting.
  • the well-known Institutions of this type have become Firefighting proven. However, you are not for the mobile independent of the fire engine Use provided.
  • the invention is therefore based on the object to develop mobile fire fighting pump unit which either individually or simultaneously both wet or Dry foam as well as water as an extinguishing agent Can provide and with little equipment Effort is light and compact.
  • This combination of a conventional mobile Fire water pump with a proportioner for one Foam concentrate, a foaming channel and one this upstream compressed air supply and the corresponding pressure and flow control devices it is possible to optionally use foam certain extinguishing effects or water or both at the same time for fire fighting from one Water reservoir, for example a natural body of water, to make available, even in places that are for Fire trucks are not accessible.
  • the pump unit which is arranged on a sled with handles, can due to their compact training in fire engines carried and due to the lightweight design carried to the final place of use.
  • the pump and the compressor to a common motor coupled, which is designed as an internal combustion engine and with an exhaust gas heater for venting the intake line of the Pump is equipped.
  • the mobile pump unit is therefore ready to use quickly.
  • the required cooling of the compressor via a Cooling circuit from one in the pressure line integrated Venturi nozzle is operated.
  • the way manufactured cooling circuit is characterized by a low outlay on equipment.
  • the mobile pump unit described below is on a slide (not shown mounted and with a cover (not shown) covered. she can be housed in a fire engine and by means of carrying handles attached to the slide for Place of use. Your essential Functional elements are a pump 1 and a compressor 2, which are driven by a common motor 3, as well as a foam agent admixer 4 and a foaming channel 5.
  • a suction line 6 is connected, which in a Water reservoir (water tank, natural water) (not shown) is sufficient.
  • extinguishing water pipe 8 branches after one Check valve 9 from a pressure line 7.
  • Flow reducing element 10 from ball valve and Baffle plate and a first shut-off valve 11 for Blocking or releasing the discharge of extinguishing water involved.
  • the pressure line 7 continues through a Venturi nozzle 12 with manometer 12a, a baffle plate 13, a water filter 14, a solenoid valve 15 with integrated pressure reduction / flow rate limitation and a ball valve 16 to the foam agent admixer 4.
  • the pressure line 7 leads from the foam agent admixer 4 via a second check valve 17 and Foaming channel 5 and a second shut-off valve 18 to the foam outlet 19.
  • the compressed air line 20 leads to air calming via an air calming boiler 21.
  • a pressure control valve 22 with manometer 23 and a compressed air discharge line 24 to supply other compressed air consumers involved.
  • the entire pump unit is connected to one central drainage 25 connected with a uniform lever system can be operated to the To drain the plant essentially as a whole.
  • the water sucked in by the pump 1 is in the Extinguishing water pipe 8 and - if the first shut-off valve is open - promoted to the water outlet 8a. If at the same time as the provision of fire water on Foam exit 19 also foam for fire fighting is to be carried out with the Flow reduction element 10 in the fire water line 8 the water discharge at 8a is reduced, so that one sufficient amount of water to generate foam Available.
  • the engine 3 is an internal combustion engine, the Exhaust line is designed as an exhaust gas emitter 3a, which the suction side is connected to the pump 1 to the in the suction line 6 existing air during commissioning suction of the mobile pump unit and a quick one and ensure trouble-free suction of water.
  • the sucked-in water is passed on through the Venturi nozzle 12, which is connected to the compressor 2 in its conically narrowing space and its diffuser-widening space to form a cooling water circuit. Adequate cooling of the compressor 2 is thereby possible in a simple manner. With the help of a baffle plate 13 downstream of the Venturi nozzle 12, the pressure of the pumped water is reduced. With the subsequent, from a central control panel (not shown) via a button Solenoid valve 15 to be actuated with integrated pressure reduction and flow rate limitation, the maximum water flow rate required for foam generation, which in the exemplary embodiment is 170 l / min, is set. or dry foam (170 l / min or 70 l / min).
  • the foam agent admixer 4 is a metering piston admixer trained - the setting of the admixing rate Foam concentrate is made with one on his Bottom provided metering rod 4a.
  • the foam agent admixer 4 is water hydraulic operated and sucks it Foam agent according to the set dosage from a container (not shown at Foam agent admixer 4 is in the pressure line 7 second check valve 17 downstream, the prevents that afterwards in the pressure line 7 and with it in the water-foam mixture over the Compressed air line 20 imported compressed air or that now formed water-foam agent-air mixture for Foam agent admixer 4 flows back.
  • the water-foam agent-air mixture (Foam) that through the Air supply is already partially foamed, now arrives in the foaming channel 5, in which it through in this built-in swirling elements 5a swirled and is intensely foamed.
  • the described mobile pump unit can thus simultaneously or alternatively with water or foam as Extinguishing agents are operated. It is compact and portable and can therefore also be inaccessible Locations are spent.
  • the compressor 2 delivers also the necessary compressed air for others Use cases and can also be used to for a short time larger throw distances for the one jet pipe to achieve spreading extinguishing foam.
  • the facility has on a control panel (not shown), on their Function is controlled from a central point. Some of the Control elements of the central control panel are the Shown in the drawing for the sake of simplicity.
  • Reference numeral 26 denotes a push button for on and Switch off the compressor 2.
  • buttons 27 and 28 for actuating the pressure control valve 22 for the Compressed air supply and a button 28 for the actuation of the Solenoid valve 15 in the water-carrying pressure line shown.
  • the on and off Foam agent admixer 4 the dispensing of wet or Dry foam through the adjustable with the ball valve 16 Amount of water, switching on or off of the pump 1 connected exhaust gas heater 3a, opening and Close the shut-off valves 11 and 18 at the water outlet 8a and / or foam outlet 19 or the Water flow reduction for water dispensing in the Extinguishing water pipe 8 with the help of the flow reduction element 10 are done using the on the control panel arranged display elements, switches and buttons (not shown).
  • the invention is of course not based on the previous one exemplary embodiment of an Pump unit limited.
