The tank body and the carriage are made separately, and a reinforced composite longitudinal support beam is provided at the bottom of the tank to provide long-term support without deformation. Each support point is equipped with a special rubber support block for anti-vibration and fatigue engineering, and an elastic connection mechanism is adopted.

Water tank accessories:

(1) 1 inlet hole with quick locking and opening device.

(2) Electronic liquid level meter × 2, installed in the tank, and displayed on the pump room instrument box.

(3) Overflow pipe: DN80mm*1

2. Pumping systemThe fire fighting truck pumping system is designed with a dedicated pump room, and rolling doors are designed on the left/right side and the rear side to open/lock. The pumping system consists of a fire pump, a pipe system, a water hose, a water gun, a joint, etc.

3. Main technical parameters of the fire pump:

Model: 8FC Manufacturer: Hill, USA

Flow rate: 166L/s @ 1.0MPa Installation type: rear-mounted

Drive type: driven by the car engine through the power take-off

Seal: mechanical seal **Suction depth: ≥7 meters

Vacuum pump: Hill ESP (DC24V), the same brand as the pump

Water diversion time: ≤100s

4. Pipeline system

Water suction pipeline: There are 4 DN150mm external water suction ports at the rear of the pump room, with special inner buckle cover, buckle seal, and reasonable design of the water suction port position, leaving enough space for the rotation of the water suction pipe and the rotation space of the suction pipe wrench, which is convenient for disassembly and assembly of the water suction pipe. Set up a DN250mm rear water inlet pipeline, equipped with a DN250 pneumatic butterfly valve, and a filter to avoid inhalation of impurities and damage to the pump body.

Water outlet pipeline: There are 3 DN80mm water outlets on both sides of the pump room, and the end of the water outlet is equipped with a manual stop valve, which is reasonably designed and easy to open and close.

Fire monitor water outlet pipeline: Water pump (through water tank)**Water monitor pipeline is DN100mm, equipped with DN100mm pneumatic butterfly valve**.

Water injection pipeline: There are 2 DN80mm external water injection ports on the left and right sides of the vehicle body. A Φ80mm tank water filling pipeline is set in the pump room, and water can be filled into the tank through a water pump, and a pneumatic ** valve is provided.

Residual water pipeline: A residual water pipe is installed at the ** position of the pipeline and the water pump, and a ball valve is provided respectively, which is set at a position convenient for opening under the pump room.

5. Intelligent integrated operating system

The fire fighting truck is equipped with an intelligent integrated operating system installed at the rear of the pump room. The system has a fully automatic pressure balance function, a high degree of automation, and is easy to operate. The integrated operating system interface can display the operating status of the chassis and pump group in real time, and the limit of the working state can be set according to the use requirements. The system will automatically report ** prompts when it detects abnormal conditions. In case of emergency, the system can realize automatic decompression, speed reduction, shutdown and other emergency treatments, with high safety.

1. Centrally display the operating status of each part of the chassis and the upper body;

2. Fully automatic pressure balance function;

3. Limit the extreme working state of the chassis and the upper body;

4. Alarm prompts for abnormal situations;

5. In an emergency, realize automatic decompression, speed reduction, shutdown and other emergency treatments;

6. Electric fire cannon

Electric fire cannon is installed on the top of the vehicle, which can be remotely controlled (wired/wireless) by remote control, and can operate the fire cannon without climbing to the top, improving combat efficiency. The main parameters of the electric fire cannon are as follows:

7. Equipment compartment: The outer frame is an aluminum alloy frame structure, and the inner frame is made of 40*40/40*80 aluminum alloy profiles through aluminum triangle supports and stainless steel bolts. The outer skin is made of electrophoretic pre-sprayed paint filmed red aluminum plate, which is tightly bonded to the frame through imported special high-strength adhesive materials, and the seams are sealed to prevent electrochemical corrosion. The interior panels and bottom panels of the equipment compartment are made of anodized flat aluminum plates bonded by imported aviation adhesives (no rivets), and other metal parts on the vehicle are made of anti-corrosion materials. The footrest and the roof of the equipment compartment are paved with patterned non-slip aluminum plates. The basic principles for the storage and layout of various fire-fighting equipment in the vehicle:

(1) Design equipment integration according to combat organization and combat deployment;

(2) Design various equipment brackets according to ergonomic principles;

(3) The principle of simple and practical access to any equipment in the box without any climbing tools.

(4) Place equipment according to the logical relationship and frequency of use;

(5) Access any equipment within 1-2 movements while standing on the ground or on the pedals.

(6) Configure and place the equipment according to the frequency of use of the equipment and the needs of actual firefighting.

(7) Use special clamps that are rust-proof, vibration-proof, anti-falling, and anti-scratch to fix the equipment.
