Introduction to the configuration and functions of the Dongfeng Tianlong vehicle with auxiliary engine for cleaning and sewage removal: This vehicle is equipped with a 400-horsepower auxiliary engine to drive a large-flow water circulation pump. The tank body of the high-pressure cleaning and sewage removal vehicle is designed as an integrated unit: The clean water tank and the sewage tank can be divided into separate tanks according to customer requirements, and can be designed for either integrated mode or separate tank mode for better meeting customer needs. The water tanks are made of 8mm high-quality national standard carbon steel plates, with internal compartment design and anti-corrosion treatment. The water in the clean water tank is pressurized by an imported high-pressure pump, which can effectively impact the blockages. The sewage tank adopts the vacuum suction principle and can achieve self-suction and self-discharge functions.
Description of the high-pressure cleaning system for the Dongfeng Tianlong vehicle with auxiliary engine and suction cleaning unit: The high-pressure cleaning system uses a German-made high-pressure pump (22mpa, 215l/min), equipped with a 60-meter (Φ19) high-pressure hose, and is connected to 10 domestic high-pressure cleaning nozzles or 2 imported spray heads.
The Dongfeng Tianlong front-four rear-eight cleaning and sewage suction vehicle adopts the Dongfeng Tianlong front-four rear-eight DFH1310A1 chassis, with 8×4 drive, a D310 flat-head high-top double-seater cab, Dongfeng dCi420-51 (diesel - high-pressure common rail + SCR after-treatment), wheelbase 2050 + 4400 + 1350 mm, frame front width 940 mm, rear width 860 mm, all-aluminum 580L main fuel tank, Shaode 12-speed 12JSD200TA gearbox, 5T double front axles, 10T single-stage reduction double rear axles, frame longitudinal beam section size 280×90×(8+4) mm, steel spring plates 3/3/10, 12R22.5 radial tires, Dongfeng Technology 4-channel ABS, full-floating cab suspension (front and rear suspension with mechanical springs - with lateral shock absorbers), hydraulic electric flip, electric glass wiper, central control - remote control front door lock, airbag shock-absorbing driver’s seat, channel-type instrument panel, equipped with air conditioning.
Standard equipment for the Dongfeng Tianlong vehicle with auxiliary engine for cleaning and suction: 400 horsepower auxiliary engine, sandwich type power take-off device, 2 hydraulic lifting cylinders, 2 rear locking small cylinders, 1 high-flow high-pressure pump and water circulation pump, 1 steel wire rubber suction pipe, 1 oil-gas separator, 1 water-gas separator, 1 set of alarm system inside the tank body, 1 viewing window for sewage, and other standard equipment.
1. The tank is made of carbon steel. The cutting of the tank body and key components is accomplished using a domestically advanced fully computerized underwater plasma cutting machine. The dimensions are precise and the shape is regular.
2. The butt welding of carbon steel plates is carried out using a fully automatic butt welding machine that is relatively advanced in the industry. The weld seams are smooth and uniform, and the quality is reliable.
3. The tank body is formed using a more advanced technology in the industry - a single roll forming machine for one-time forming. This completely eliminates the circular welds formed by the old process, ensuring that the formed tank body is structurally sound, leak-proof, has a beautiful appearance, good straightness, and avoids excessive contact between the welds and the main beam. Its working intensity is three times that of the circular welds.
4. Inside the tank, multiple scientifically designed and highly reinforced anti-wave corrugated partitions are installed in accordance with national standards, enabling the entire vehicle to adapt to driving on various road conditions.
National VI Dongfeng Tianlong vehicle with auxiliary engine for cleaning and suction operation
1. Powerful function: It has multiple functions such as drainage, sewage suction, and sewage cleaning, with a capacity of 3 vehicles per unit.
2. Sandwich power take-off unit: It provides full power output with low noise. It takes power from the chassis engine and separately supplies it to the vacuum pump and high-pressure water pump. This enables multi-point high-power power extraction with relatively low power loss.
3. Vacuum Pump: Ultimate vacuum level: 33 mbar, pumping capacity: 1400 m3/h. Operating speed: 1300 r/min. Water ring vacuum pump, Siemens technology, domestically produced.
4. High-pressure water pump: Rated pressure: 24 MPa, Rated flow rate: 212 L/min, Rotational speed: 1450 r/min. High-pressure piston pump, jointly produced by China and Germany.
5. Cleaning hose: A PVC steel wire reinforced hose or steel wire woven rubber hose with a rotating boom, capable of rotating 230° horizontally, extending vertically by -15° to +53°, and having a 1.3m length of telescopic extension. Three 1.8m extension tubes are provided for extending the cleaning hose.
