Isuzu GIGA fire powder truck is an indispensable equipment for fire brigade because it can quickly extinguish Class A, B, and C fires (especially flammable liquid, gas and electrical fires). Based on years of experience, CEEC factory has served thousands of customers who purchased fire trucks and formulated relevant fire truck manufacturing standards. Today, let's learn about the core standards for making a high-quality Isuzu fire powder truck:
1. Excellent chassis and power system
♦ Carrying capacity: It must be able to stably carry the weight of the full load (dry powder, nitrogen cylinders, water tanks, equipment, personnel) and leave enough safety margin. CEEC fire truck factory usually selects high-quality heavy truck chassis (such as Mercedes-Benz, Volvo, MAN, Isuzu GIGA, domestic heavy truck/Shaanxi Automobile and other well-known brands).
♦ Engine power: Provide sufficient power to drive the fire truck, and at the same time supply power to the on-board air source (air compressor), hydraulic system, and electrical system. The engine must have good adaptability to plateaus, high temperatures, and low temperatures.
♦ Drive form: According to the road conditions in the jurisdiction, CEEC engineer can customize the all-wheel drive (4x4, 6x6) system, which is crucial for complex terrain (construction sites, fields, rugged roads).
♦ Braking system: Equipped with efficient and reliable braking systems (such as disc brakes, retarders) to ensure full-load downhill and emergency braking safety.
Suspension system: High-quality suspension system ensures driving stability and passenger comfort, and reduces equipment vibration damage.
2. Core dry powder system
♦ Capacity: Choose the appropriate capacity (commonly 1 ton, 2 tons, 3 tons, 5 tons or even larger) according to the application scenario (such as chemical plants, airports, urban rescue). The tank body must be strong enough to withstand the working pressure (usually 6-8 bar).
♦ Material: High-quality stainless steel or carbon steel with special anti-corrosion treatment on the inner wall to ensure that the dry powder will not deteriorate, agglomerate, be moisture-proof, or be corroded and contaminated during long-term storage.
♦ Fluidization design: The tank bottom design (such as cone bottom, with fluidizing plate/fluidized bed) and the built-in fluidizing gas pipeline must be scientific and reasonable to ensure that the dry powder can be fluidized and output smoothly, evenly, and completely to avoid residue or bridging.
♦ Sealing: The tank body, manhole cover, pipeline interface, etc. must have excellent sealing performance to prevent moisture intrusion and dry powder caking.
3. High-pressure nitrogen drive system
♦ Large-capacity high-pressure nitrogen cylinder group: Provides the inert gas required to drive the dry powder. The capacity of the cylinder group (water volume) must match the amount of dry powder to ensure that all dry powder can be effectively emptied. Carbon fiber wrapped bottles are usually used (lightweight and highly safe).
♦ Pressure reduction and stabilization system: Precise and reliable multi-stage pressure reducing valves can stably and accurately reduce high-pressure nitrogen (30MPa) to the working pressure (6-8 bar) required by the dry powder tank, and maintain stable pressure during the injection process, which is the core to ensure uniform dry powder injection and stable range.
♦ Pipelines and valves: High-pressure pipelines and valves (stop valves, safety valves, check valves, etc.) must comply with high-pressure gas specifications, be made of reliable materials (such as stainless steel), have firm connections, and no risk of leakage.
4. High-efficiency dry powder gun and spray system
♦ Range: Under standard working conditions (dry powder quantity, pressure, wind speed), it can reach the designed range (such as ≥ 40 meters) and cover a sufficiently large fire area.
♦ Flow rate: High spray rate (such as ≥ 5kg/s), which can quickly suppress the fire.
♦ Maneuverability: Large horizontal rotation angle (≥270°), reasonable pitch angle (such as -15° to +70°), light and flexible operation (hydraulic or pneumatic drive is better than pure manual).
♦ Dry powder hose reel: Equipped with at least 1-2 sets of hose reels with dry powder spray guns (usually 20-40 meters) for close combat and precision fire fighting. The reel should operate smoothly, and the spray gun switch should be flexible and reliable.
♦ Pipeline system: The dry powder delivery pipeline (from tank to gun/reel) is reasonably designed, with a smooth inner wall (usually stainless steel or Teflon lining), few elbows and gentle angles, minimizing flow resistance and preventing dry powder deposition and blockage.
5. Intelligent and reliable operation control system (control panel)
♦ High integration: All key operations (gas source start and stop, nitrogen cylinder group switch, pressure reducing valve adjustment, dry powder tank pressurization/depressurization, dry powder gun/reel control) are concentrated on the wind and rainproof panel at the rear of the driver's cab or on the side of the vehicle.
♦ Intuitive display: Clearly display key parameters: dry powder tank pressure, nitrogen cylinder group pressure (high pressure side and low pressure side after decompression), air compressor status, system fault alarm, etc.
♦ Easy operation: The layout of buttons, switches, and instruments is reasonable, the labels are clear, and they are ergonomic, which is convenient for firefighters wearing heavy protective clothing to operate quickly and accurately, especially in emergency and pressure environments.
♦ Reliability: Electrical components, pneumatic/hydraulic components are of high quality, with high protection level (IP65 or above), shockproof, dustproof, waterproof, and corrosion-resistant.
