Main structure &performance features

Chassis Auxiliary engine Water Cistern Spray system Low pressure cleaning system

1.Chassis
Chassis. The chassis of Tianlong dfh1250d4 class II vehicle produced by Dongfeng Motor Co., Ltd. is refitted with strong power and strong bearing capacity. The chassis is the most advanced and reliable national six emission commercial vehicle chassis in China.
Engine. Dongfeng Cummins D6 7NS6B290 diesel engine, with rated power of 213kw and rated speed of 2300r / min, the emission meets the national six standards.
2.Auxiliary generator and its transmission device
Auxiliary engine. Dongfeng Cummins QSB5 The 9-C210-30 diesel engine has a rated power of 154kw and its emission meets the third national standard. The hydraulic oil pump is directly connected with the engine output shaft through the elastic coupling. At the same time, the program protection of load ramp start is set to prolong the service life of auxiliary engine and hydraulic system.
3.Water Cistern
The maximum volume of water tank reaches 14m ³。 It is made of Q235A high-quality carbon steel, the thickness of tank body material is 5mm, the thickness of front and rear head material is 6mm, and the tank is welded and formed; Finite element analysis is adopted to achieve lightweight on the basis of reliable structural strength; Aksu paint is standard, with good anti-corrosion effect.
4.Spray system
Air cannon. The newly designed "bullet head type airfoil diversion low noise multi-stage impeller" has low noise and high efficiency. The maximum distance of the spray is over 130m, and the pitch angle is -10 to 60 degrees.
Spray water supply. An independent waterway system (hydraulic system drives the water pump) is used to supply water to the air cannon. The waterway is equipped with a fine filter to avoid nozzle blockage. An atomizing nozzle with small outlet diameter is used to improve the atomization effect.
5.Low pressure cleaning system
Low pressure cleaning system. The two-stage centrifugal pump is driven by the power taken from the side of the chassis. It is equipped with the functions of front duckbill, middle conical flushing nozzle, rear watering and water cannon, which can meet the needs of different working conditions.
6.Operation mode
The vehicle adopts "CAN bus distributed control, authority distribution in the vehicle and multi-point operation". The integrated control box in the cab can control all operation functions of the vehicle. When some operation control needs to be carried out outside the cab, it can be switched to "wireless remote control" or "bus panel" for operation.

Integrated control box. It is located on the right side of the driver's seat and is used to control various actions of air cannon operation or cleaning operation.
Bus panel. It is located below the right side of the rear operation platform and is mainly used to control some actions of air cannon operation.
Color video rear view system. A camera is installed at the rear of the vehicle and a color display screen is installed in the cab. During the operation of air cannon, the operation status of air cannon can be monitored in the cab to avoid collision.

Main technical parameters

Main advantages

Superior performance
Pitcher. Finite element analysis is adopted to achieve lightweight on the basis of reliable structural strength; Aksu paint is standard, with good anti-corrosion effect. The maximum volume of water tank reaches 14m ³， Under the maximum spray flow condition, it can satisfy the spray operation for 1 hours. Low water level alarm is set to avoid damage to the water pump due to no water operation.

Spray system. Two stage impeller combination to increase wind pressure and wind speed. The newly designed nylon blade is used to greatly reduce the operating noise level and adjust the noise spectrum to a more soothing band for human ears. The application of nylon material can lighten the blade, reduce the impact force when the air gun is started, and protect the hydraulic and power system.
The combined design of bullet head diversion inner cone and arc nylon deflector ensures the efficient conversion of air flow in the air duct, reduces energy loss and fuel consumption; Add silencing device to the outer cylinder to reduce the operation noise of air cannon.
Using independent wind gun water supply system, the chassis speed is not restricted by side force when spraying. 3 spray rings are individually controlled to meet different water requirements.
The speed of the fan can be stepless adjusted to meet the needs of different spray distances. The automatic swing function is set up to expand the spray coverage.

Superior in quality

High accessory configuration. The main parts are international or domestic well-known brands, with excellent quality and high reliability. The chassis adopts Tianlong chassis produced by Dongfeng Motor Co., Ltd., the auxiliary engine adopts Cummins engine, and the hydraulic oil pump, motor and main oil circuit rubber hose all use well-known imported brand products.

Safe and reliable
Multiple safety protection devices and alarm systems are set. Each sensor monitors the working status of the auxiliary generator, the temperature of the hydraulic system and the water level of the water tank in real time, displays information centrally on the control box, and gives early warning in case of failure; The camera head and color display screen in the cab are convenient for the operator to monitor the installation state of the air cannon in real time to avoid collision. Warning lights, safety labels, operation music and other multiple ways are used to remind the surrounding pedestrians to avoid.
Diverse functions
Equipped with a high-performance spray system, the vehicle is equipped with a full range of low pressure cleaning functions, including duckbill flushing, taper nozzle hedging, rear sprinkler nozzle and post operation water cannon.
Easy maintenance
The spray water supply is equipped with a fine filter, which effectively reduces the blockage frequency of the nozzle and reduces the clearance. Filters, manual control valves, etc. are arranged at positions convenient for personnel operation.
