HOWO Sinotruk foam fire truck Structural principle

As a professional foam fire truck equipped with a Sinotruk light truck chassis, it has become a core emergency rescue equipment for urban fire fighting, industrial and mining enterprises, petrochemical industries, and other scenarios, thanks to its exquisite manufacturing process, advanced core technology, scientific structural design, and comprehensive practical advantages. From power output and fire extinguishing efficiency to ease of operation, every technical parameter of this Howo light fire foam truck has been rigorously refined to fully meet the needs of actual fire rescue operations, balancing professionalism and reliability.

⇒ Core Advantages:

1. Equipped with a YC4E140-33 engine, rated power up to 105KW, providing strong and stable power output.

2. Equipped with a CB10/40 atmospheric pressure fire pump, rated flow rate 40L/s, rated pressure 1.0MPa, maximum suction depth 7m, priming time ≤35s.

3. Water jet range ≥60m, foam jet range ≥48m, 360° horizontal rotation, and -35°～70° vertical rotation, enabling long-distance, no-dead-angle fire suppression coverage.

4. Equipped with a PH64 ring pump type foam proportioner, the mixing ratio can be flexibly adjusted between 3% and 6%, with a maximum mixing flow rate of 64L/s.

5. Can quickly form a dense foam covering layer, suppressing the fire through multiple mechanisms of coverage, cooling, and suffocation, effectively isolating oxygen.

6. Additional instruments and switches are integrated into the control panel, with pressure gauges, vacuum gauges, and liquid level displays clearly visible, facilitating precise operation.

⇒ Tank Body:

✺Total liquid capacity 4.0 cubic meters, including a 3000L water tank and a 1000L foam tank.

✺High-quality welded steel plate tanks with internal anti-corrosion treatment. The bottom plate is 4mm thick, the side and sealing plates are 3mm thick, and the top plate is 3mm thick carbon steel checkered plate, balancing corrosion resistance and structural strength.

✺The foam tank is made of high-quality stainless steel plate, with a 4mm thick bottom plate, 3mm thick side and sealing plates, and a 3mm thick stainless steel checkered plate on the top plate, effectively preventing foam corrosion.

✺The tank is equipped with anti-sloshing baffles to reduce the impact of liquid sloshing on vehicle stability during operation.

⇒ Fire Pump:

✺High flow rate, short priming time

✺Adopts piston vacuum pump and rear-mounted design

✺Rapid start-up and high pumping efficiency

⇒ Foam Proportioning Mixer

⇒ Piping System Design

✺The piping system uses seamless steel pipes, connected to each component via flanges.

✺Excellent sealing performance and corrosion resistance ensure leak-free water and foam supply.

✺The layout of the tank outlet pipes, external inlet pipes, outlet pipes, and injection pipes is reasonable.

✺The DN125 tank outlet pipe is equipped with a manual butterfly valve and flexible joint for a secure connection.
