New Dongfeng Tianjin 10 square fog gun truck and dust suppression truck are special vehicles to suppress dust pollution by spraying spray liquid such as dust suppression curing agent. Mainly serving railways, highways and other places with high dust incidence. Structurally, the dust suppression device is mainly composed of swing arm spray device, liquid storage tank, self-propelled vehicle and control system. In winter, the storage tanks, nozzles and pumps in the northern region need to be equipped with insulation and heating systems to work normally. Dust suppression mainly uses the interaction between hydraulic system and electric control system, that is, mobile spraying equipment injects spraying liquid into the liquid storage tank of the liquid distribution station and goes to the spraying point by itself; When the train passes, the photoelectric detection system begins to identify the traction locomotive. After the traction locomotive passes, it sends a signal, and the controller controls the transmission hydraulic system to rotate the liquid distribution pipe orthogonal to the carriage, and at the same time starts the liquid pump to start spraying. And adjust the flow of the liquid pump to meet the design spraying standard. The photoelectric detection system sends a signal to PLC between the train hooks, and controls the stepper motor or servo motor to rotate the shielding roller to stop spraying and spraying through the transmission connection device. When the train passes completely, the equipment stops spraying.
Chassis configuration: Dongfeng Tianjin Guowu chassis, Cummins 180 HP engine, wheelbase 4700mm, 6-speed gearbox, 9.00 steel tire with spare tire, ABS.
Upper configuration: water tank volume: 1 1.3 cubic meters. The inside of the fuel tank is anticorrosive. The tank steel plate is made of Q235 carbon steel. Standard 1 antiaircraft gun, gravity valve and fire connector, 2 water pipes and high-power self-priming pump. Optional 60-80m sprayer.
Optional configuration: medicine tray, indoor pneumatic operation, large duckbill 1 pair, Honda pump, cannon, long warning light, tank side with gate, spraying device, Veyron small pump/large pump, LED arrow light installed behind the tank; Full-vehicle large-caliber ball valve; Anti-rust and anti-corrosion treatment can also be selected in the tank.
Function configuration: It is equipped with front pavement flushing spraying device, rear fan-shaped dustfall spraying device, spraying devices on both sides, rear working platform and green water spray gun installed on the platform (the spray shape of the gun can be adjusted), which can continuously adjust the direct, large, medium and Mao Mao rain. The maximum range can reach 28 meters, the vertical suction distance is 6.5 meters, and the lift force 14 meters. In addition, an efficient vehicle-mounted air supply sprayer was installed. With fire interface and self-flow valve, it can be self-suction and self-discharge.
Multi-directional chart shows:
Dongfeng Tianjin 60m multifunctional fog gun vehicle;
1. The generator set is large and installed behind the cab.
2. Silent cover to protect the generator set, waterproof and dustproof, and reduce noise.
3. The finite element analysis method is used to optimize the tank, which makes full use of the vehicle space. The water tank has a large volume and passed the strict reliability test. The inside of the tank is treated with anti-corrosion and anti-rust, which is more durable.
4. The rear platform is widened and the carbon steel plate at the bottom is encrypted.
5. The wiring of the fog gun electric control box is assembled by a professional electrician, which is safer and has a higher safety factor, and it is not easy to leak electricity and short circuit, which is no better than that of a small factory. The sprayer is equipped with an emergency stop button, which is safe and reliable to operate.
6. Gun barrels are equipped with devices to reduce noise and not disturb people.
7. The fog gun has independent patents, compact structure, long range, fine fog droplets and large coverage area, and can be operated manually or remotely.
8. Completely low emission: because there is no auxiliary engine, the emission is reduced, which fully meets the current national V standard.
9. Long service life and low maintenance cost: the vehicle structure design is reasonable and the maintenance is convenient; The vehicle runs stably, always in the best running state, with longer service life and low maintenance cost.
