Split-type tankThe Isuzu 14000 liters combined jetting vacuum truck is a highly efficient and versatile vehicle specifically designed for municipal pipeline dredging. It is equipped with a robust and stable 4HK1 engine and an MLD 6-speed transmission. The upper structure features a 4m³ freshwater tank and a 10m³ sewage tank. The vehicle integrates dual systems—high-pressure cleaning (with a 24MPa triplex plunger pump) and vacuum sewage suction (powered by an SK-12 water circulation pump)—enabling integrated "flushing-suction" dredging. Design elements such as hydraulic drive, overflow alarm, and safety pressure relief ensure operational safety, making it an ideal choice for urban drainage system cleaning and maintenance.

Technical drawing of ISUZU FTR 14cbm combined jetting truck

▶ Chassis Configuration:
• Model: Isuzu FTR 4X chassis
• Wheelbase: 5000mm
• Engine: 4HK1-TCG60 high-pressure common rail diesel engine, with a power output of 205HP (151kW) and a torque of 647N.m
• Transmission: MLD 6-speed manual transmission
• Power Take-Off (PTO): Jiashan brand full-power PTO, featuring high transmission efficiency and meeting the power requirements of both the high-pressure pump and the liquid ring pump.

▶ Superstructure Configuration:
1. Tank Material: Q355 high-strength carbon steel, offering corrosion resistance, impact resistance, and a long service life.
2. Tank Design:
• Dual-Tank Configuration: The vehicle is equipped with two circular tanks—a 4m³ cleaning water tank (4mm thickness) and a 10m³ sewage tank ( 6mm thickness). These tanks operate independently without interference.
• Lifting System: The sewage tank is hydraulically lifted, with a dumping angle of ≥45°, ensuring high emptying efficiency.

• Rear Cover Opening: The rear cover is hydraulically driven and features a wheel-type manual locking mechanism, providing tight sealing and easy operation.
• Cleaning water Tank Access: The top of the freshwater tank is equipped with a DN500 manhole, and an internal ladder is provided for easy access.
3. Safety Design: The side platforms are fitted with mesh guardrails and anti-slip checkered plates to ensure the safety of operators.

▶ Sewage Suction System:
1. Vacuum Pump: SK-12 water circulation vacuum pump
• Air Extraction Rate: 12 m³/min
• Maximum Pressure: 8,000 Pa
• Function: Capable of suctioning sludge containing solid particles and a small amount of moisture.

2. Safety Devices:
• Overflow Prevention: Equipped with a pneumatic anti-overflow valve and a high liquid level alarm in the tank to prevent sewage from entering the vacuum pump.
• Pressure Relief Valve: An safety pressure relief valve is installed to prevent system overpressure.
3. Pipeline Connections:
• Suction Port: DN100 (with quick-connect coupling).
• Discharge Port: DN150 large-diameter discharge port for rapid unloading.
▶ High-Pressure Cleaning System:
1. High-Pressure Pump: Tianjin Tongjie 3N2 triplex plunger pump, with a rated pressure of 24 MPa and a flow rate of 170 L/min, delivering powerful cleaning performance.
2. Hose Reel and Hose: A 60-meter, ∮19 side-mounted high-pressure hose reel, hydraulically driven, equipped with 10 high-pressure nozzles offering multiple spray patterns for versatile cleaning.


▶ Operation:
Right-side Multi-way Valve: Equipped with a Zhongmei multi-way valve, enabling sensitive and precise hydraulic control. The lifting of the sewage tank, opening/closing of the sewage tank tailgate, and operation of the high-pressure cleaning hose reel are all stable and free from jams.
