Parameter characteristics of Dongfeng Tianjin washing and sweeping truck

Functional characteristics of Dongfeng Tianjin washing and sweeping truck
1. Function introduction
1) The truck setRoad sweeper,sprinklerwithHigh pressure cleaning truckThe functions are integrated, and the functions of cleaning, high-pressure cleaning, road washing and sewage collection can be completed in one operation.
2) Adopt the operation device arrangement of "two vertical sweeps in the middle + wide suction nozzle in the middle (built-in high pressure water spray rod) + high pressure side spray rod in the middle". It has many functions such as pavement cleaning, pavement scrubbing, high-pressure cleaning, curb scrubbing, garbage collection, sewage recycling, high-pressure spraying and road separation wall cleaning.
3) Adopting advanced intelligent control method, when operating, only after selecting the operating mode, the start and stop of each operating mechanism are automatically controlled by the program. The operation modes include full washing and sweeping operation, left washing and sweeping operation, right washing and sweeping operation, full sweeping operation, left sweeping operation, right sweeping operation and pure suction operation.
4) Equipped with advanced voice prompt alarm device, which can accurately broadcast various safety prompts and broken downs. The whole vehicle has a reverse protection device, which can automatically retract the working device when reversing.
5) Adopt a center-mounted double-suction super-wide suction nozzle with a diameter of 180mm. Its built-in long row of high-pressure water spray rods have small ground clearance and large water impact force, which can directly send sewage to the suction port, with less operation splash and high sewage absorption rate. It can also adjust the washing angle of the long row of nozzles on the road surface according to the pollution of the road surface to make the cleaning effect better.
6) The auxiliary engine is equipped with a vehicle clutch. When starting and stopping, the cylinder drive clutch is disengaged, and it is connected after a delay. The separation and engagement of the clutch is automatically controlled by the electronic control system without manual operation, which effectively avoids damage to the fan, high-pressure water pump, and engine.
7) The high-pressure water pump is imported from Germany. When the high-pressure water pump is started and the working water valve is switched, the water pump can automatically unload. Through the triple protection of air circulation, safety valve and overflow valve, it can effectively prevent damage to the high-pressure water pump.
8) The anti-overflow alarm device and high-pressure spray cleaning device are installed in the garbage bin. The anti-overflow alarm device can prevent the sewage from overflowing from the suction pipe and cause secondary pollution; the high-pressure spray cleaning device can automatically clean the sewage tank after dumping the garbage, which greatly reduces the labor intensity of the operator. The rear part of the truck is equipped with a mechanical automatic winding and washing reel, equipped with 18m high pressure hose, which can be used forCleaning truck Body and other equipment and facilities.
9) There is a low water level sensor alarm system in the water tank, which automatically alarms when there is no water to prevent the water pump from being damaged by water shortage.
10) A high-definition surveillance probe is installed on the right sweep pan and the rear of the trash bin, and a high-definition LCD display is installed in the cab. The screen can be switched to the right sweep pan and the rear of the trash bin. During operation, you can scan the tray The working conditions and the quality of the whole vehicle operation are monitored.
11) The hydraulic system gear pump adopts domestic high-quality pumps with reliable performance. The valve manufacturer is one of the most professional hydraulic component manufacturers inter Euro ly recognized.
12) A manual pump is added to the hydraulic system, so that when the system encounters special circumstances, such as the auxiliary engine cannot work normally, the manual pump can be used to complete the dumping of garbage and the reset of each hydraulic cylinder. With anti-hydraulic leakage function.
13) The electrical system adopts PLC program automatic control, and the controller adopts German original imported brand, with reliable performance.
2. Features introduction
1) Adopting Dongfeng Tianjin DFL1160BX5 Type II vehicle chassis modification, the engine is Cummins Euro IV emission. The auxiliary engine is Cummins EQB160-20;
2) Adopt the arrangement of clean water tank in front and garbage bin in rear, semi-enclosed auxiliary engine compartment, left and right corner doors + double side doors, easy access for personnel, compact overall structure and convenient maintenance;
3) The grounding pressure of the side sweeping brush system adopts a spring adjustment method, and the sweeping grounding pressure can be adjusted at any time according to the road conditions during work to reduce the wear of the sweeping brush;

4) High-pressure water pumps and water nozzles are all imported products. The water pump is a stainless steel pump head with a pressure of up to 160 Bar and a maximum flow of 154 L/min, which has a better washing effect on the road;
5) The hydraulic valve in the hydraulic system adopts electromagnetic reversing valve, which is neatly arranged and easy to maintain. The hydraulic motor adopts imported brand products. The hydraulic system of the whole vehicle runs reliably, the action is sensitive and effective, and there is no creeping phenomenon of moving components;

6) Special high-pressure centrifugal fan, the maximum air volume can reach 12000m3/h, the blade material is made of special steel, and its special blade shape is extremely difficult to wear;
7) The unique side sweeping brush anti-collision mechanism can effectively protect the side sweeping brush mechanism and avoid damage caused by the flushing device hitting the teeth at any time;
8) Adopting the working method of sweeping first, scouring later, and absorbing again, it can sweep, scour and absorb garbage and sewage at one time. There is no dust and no water after pavement operation;
9) The high-pressure water circuit is equipped with a quick plug-in anti-freezing water blowing device interface to prevent the water circuit components from being damaged by freezing at low temperatures in winter;

10) The trash bin is made of stainless steel plate, which has excellent anti-corrosion performance;
11) The key components of electrical components adopt high-quality imported components, and the operation control adopts one-key operation, which can realize 9 operation modes, and the control adopts PLC programming controller;
12) Adopting cylinder drive and electric automatic control of vehicle clutch to ensure that the auxiliary engine starts without load, stops without load, and prolongs the service life;
13) Equipped with a flushing winch and flushing gun with automatic retractable function, the flushing gun has a large flow rate and high pressure, which can forcefully flush local oily areas and can flush small advertisements;

14) With voice alarm device, it can realize broken down self-diagnosis function;
15) A row of high-pressure nozzles are installed on the rear protective fence, which has the function of spraying and reducing dust;

16) With low pressure flushing function, the maximum flushing width can reach 24m.
17) The box body adopts triangular bending shape, with novel appearance and high strength.
