✦Ⅰ.Product Parameter For HOWO Fire Water Truck «««

✦Ⅱ.Fire Pump System Of HOWO Fire Water Truck «««

This is the true "heart" of the fire truck. The entire system consists of: engine → transmission → PTO (Power Take-Off) → driveshaft → CB10/60 XZ fire pump. The engine not only drives the vehicle but also diverts power via the PTO to specifically power the fire pump, pressurizing and outputting water for firefighting. Simultaneously, the HOWO light fire truck can also mix foam media for emergency rescue in special fire situations.

1.Power Matching Verification: The output speed of the PTO (Power Take-Off) must match the rated speed of the CB10/60 RS pump.The power margin should be reserved to avoid insufficient power and the pump failing to reach its rated pressure under full load.

2.Driveshaft Coaxial Alignment: The three driveshafts (gearbox PTO, PTO fire pump) must be coaxial. Misalignment will cause vibration, rapidly wear down the driveshaft bearings and the pump's mechanical seal, leading to leaks and abnormal noises.

3.Sealing Surface Installation Specifications: Clean the old gaskets and impurities from the PTO-gearbox mating surfaces and the pump body flange surfaces. Apply sealant evenly and use brand-new sealing paper gaskets. Do not reuse old gaskets to prevent air intake and oil leakage.

4.Piping Layout: Keep the suction pipe as short as possible with minimal bends. Excessive bends in the pipe will increase suction resistance and directly reduce water intake capacity. All flange connections must be equipped with complete rubber sealing rings.

5.Electrical wiring: The circuits of the double piston priming device, pressure switch, and residual water switch must be reliably grounded. The residual water switch function must be properly connected and dry-run protection must be provided to prevent the pump from running dry and burning the seals.

✦Ⅳ.Fire Foam System Of HOWO Fire Water Truck «««

✅The foam proportioning device mixes foam concentrate with water at a preset ratio. Using the pressure differential principle, it draws foam liquid from the foam tank and blends it evenly into the water stream. The mixed foam solution is then delivered to the fire pump and fire monitor for fire suppression.

✦Ⅲ.Advantage Of HOWO Fire Water Truck «««

1. Powerful Performance and Adaptability to Complex Terrain：

♦ Equipped with a high power diesel engine, the vehicle delivers stable performance during startup, acceleration, and hill climbing.

♦ The chassis features a high load bearing capacity, accommodating a water tank, foam tank, equipment compartments, and multiple crew members.

♦ A multi axle drive system combined with a high performance braking system ensures excellent off road mobility and safety.

2. Large Capacity Water Tank and Foam Proportioning System：

♦ The large capacity water tank supports sustained water supply, reducing the need for frequent refilling at the scene.

♦ A foam proportioning system allows for the adjustment of the water-to-foam ratio based on the specific type of fire.

♦ The tank layout is optimized to ensure a more stable center of gravity.

 

3. Efficient Pumping and Discharge Capabilities：

♦ Equipped with a high flow fire pump that provides consistent discharge pressure.

♦ Roof mounted and mid mounted monitors (water cannons) enable long range fire suppression.

♦ The system allows for rapid switching between water supply, foam application, and discharge modes, minimizing response times.

 

4. Specialized Equipment Compartments and Rapid Access Design:

♦ Large capacity compartments on both sides of the vehicle allow for the organized storage of fire hoses, couplings, forcible entry tools, protective gear, and rescue equipment.

♦ Aluminum alloy roller shutters ensure smooth operation and excellent sealing.

♦ Modular mounting brackets inside the compartments keep equipment neatly arranged, facilitating quick identification and retrieval during emergencies.
