Washing and sweeping trucks refer to vehicles that are responsible for cleaning, washing, and cleaning roads in urban areas, national highways, highways, etc. The vehicle is equipped with two brush disks and a wide suction cup in the middle, or four-disk sweeping and rear suction port type road operations vehicle.
product description:
Sweeping truck is a new generation of road cleaning and sweeping truck restructured by adopting the second-class chassis of Dongfeng, Isuzu, JAC, BYD, and Dongfeng.
The vehicle can be used as a road sweeper alone for road cleaning and suction operations; it can also be used as a high-pressure washing vehicle for road surface cleaning and suction operations;
It can also be used as a cleaning vehicle with a combination of road cleaning suction and high-pressure flushing to achieve multiple combinations of cleaning, washing, and pumping to meet the various needs of different users. The vehicle can be widely used in urban main roads And the washing and cleaning operations of viaducts.
working principle:
The washing and sweeping truck adopts two brush trays in the middle, a wide suction cup in the middle, and a V-shaped high-pressure flushing frame with anti-collision and obstacle avoidance functions to form a washing and sweeping belt larger than 3.5 meters.
Cummins EQ6BT5.9-118 auxiliary engine is used. At this stage, there is also a driving device that uses electric power as the power to be horizontally placed in the middle of the frame, and a suction fan controlled by a pneumatic clutch device is arranged on the left side of the power compartment.
The water tanks and trash bins made of stainless steel are all constructed with square tiles. The water tank is divided into two parts, one is a front independent water tank, which is assembled at the front of the power bin; the other is a water tank arranged at the front of the trash bin, which can be lifted and lowered simultaneously with the trash bin and the power bin cover.
The dustbin with lifting function is equipped with a high-pressure flushing nozzle, which makes the unloading easier and clean. The power bin cover that can be lifted with the trash can makes the maintenance of the power system extremely convenient.
The use of well-known and high-quality supporting components in Europe and the United States makes the vehicle performance better and more reliable.

Operation tutorial:
The washing and sweeping vehicle sprays high-pressure water for cleaning operations, so the use and operation methods are wrong, which may lead to human accidents, and should be operated with caution.
(1) If the silt is not cleaned once, the cleaning and sweeping can be repeated.
①. During the cleaning operation, if the pressure is stable, to protect the pressure gauge, the pressure gauge switch can be turned off. However, as soon as there is a change in working conditions, the pressure gauge switch should be turned on immediately to monitor the pressure change
②. If the water level is at a dangerous level, immediately stop the operation and add water;
(2) Retreat and clean the car
①. One person operates the hose holder to protect the high-pressure hose
②. Insert the tube reel handle into the “retracted” position, and insert the high-pressure hose by rotating the tube reel counterclockwise;
③. Adjust the speed of the pipe according to the amount of sludge by adjusting the speed knob;
④. Open the tube washing needle valve;
⑤. Increase the hand throttle to make the water pump clean at 1000-1200 rpm again;
⑥. When the nozzle is close to the entrance, lower the throttle so that the water pump rotates at a short speed until the sewer is cleaned;
(3) The parking position of the washing and sweeping vehicle during sewer cleaning operations
①. The cleaning vehicle should be parked in a straight line at the sink well of the sewer. If the parking position is not appropriate, the operation efficiency will be reduced at the same time, and the hose life should be replaced;
②. The cleaning vehicle should be parked at the downstream wellhead of a section of sewer to be cleaned, and the vehicle should be parked downstream;
a. When the pipeline is completely cooled and the sediment is deposited, the cleaning operation should be started from the caisson at the most downstream of this section;
b. Generally, cleaning operations can be started from the upstream caisson;
(4) Drive operation of water pump of washing and sweeping vehicle
Some things should be checked before driving:
Operation cabinet:
①. Place the hand throttle in the “small” position;
②. Set the high-pressure three-way valve to the “backwater” position;
Hydraulic system:
①. Whether the fuel tank is filled with enough oil;
②. Whether the two stop valves under the fuel tank are open;
Waterway system
①. Whether the water tank is filled with clean water;
②. Whether the termination valve is open;
③. Whether there is a blockage on the filter;
④. Check the amount of lubricating oil in the gasoline tank of the water pump;
Key points: place the handle of the coiling tube at the “stop” position; place the speed control pointer at the “slow” position; place the pressure gauge switch at the “off” position;
place the tube washing at the “off” position; after confirming that the above dimensions are in the correct position , Start the engine, move the water pump clutch lever on the transfer case back, the water pump can rotate at low speed;
(5) General precautions for washing and sweeping vehicles
①. During the operation, the operator shall not leave the operation cabinet, and the armor shall deal with the unexpected accident in time;
②. When working, first use the pipe holder to send the nozzle into the pipeline, and then open the three-way valve, not close to the nozzle, so as not to hurt people;
③. Do not use high pressure for water delivery, car washing, and wall cleaning;
④. Clean water should be used. Excessive sewage can prolong life and cause cavitation when used;
(6) Water supply method for water tank of washing and sweeping vehicle
①. Before supplying water, check and clean the filter;
②. Screw one end of the water delivery belt into the fire hydrant or water supply truck, and screw the other end into the water tank on the right side of the water tank;
③. When power is supplied, the water level can be observed from the water level gauge on the dashboard.
Performance characteristics:
● The road surface is scrubbed by the combination of scrubbing and high-pressure cleaning, garbage collection, sewage recycling, and hydraulic tipping and unloading.
● Adopt auxiliary engine or electric motor and hybrid power system to drive high-pressure water pump, fan and working device.
● Integrate the functions of a road sweeper and a high-pressure cleaning vehicle to realize the completion of cleaning, high-pressure cleaning, garbage and sewage collection in one operation.
● It has many functions such as road cleaning, road scrubbing, high-pressure cleaning, curb scrubbing, garbage collection, sewage recycling, spraying and road separation wall cleaning.
● It has a technologically advanced high-pressure waterway control system. When the high-pressure water pump starts and the working water valve is switched, the water pump can automatically unload.
● It adopts the operation device arrangement mode of “center-mounted two vertical sweepers + center-mounted wide nozzle built-in high-pressure water spray rod + center-mounted high-pressure side spray rod”, which is the first in China.
Compared with other arrangements, it has the characteristics of centralized operation equipment, constant distance between nozzles and the ground, continuous and smooth operations such as scrubbing-flushing-sewage absorption, less splashing, high sewage absorption rate, large cleaning width, and high cleaning efficiency.
● Adopt special sweeping disc and sweeping brush with patented technology, which can simultaneously scrub the road surface, curb, curb facade and upper surface.
● The left and right high-pressure side spray rods and suction nozzles are arranged in a “V” shape, hydraulically operated and retracted, and the “V”-shaped angle and the angle of the high-pressure water nozzle can be adjusted. The water flow has a large impact force and can efficiently collect sewage. There are anti-collision and automatic reset functions.
● The suction nozzle has a built-in long row of spray rods, the nozzle has a short distance from the ground and the impact force of the water flow is large, which can directly send sewage to the suction port.
According to the pollution of the road surface, the washing angle of the long row of nozzles can be adjusted to achieve the best cleaning effect.
● 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 causing secondary pollution;
The high-pressure spray cleaning device can automatically clean the sewage tank after dumping garbage, which greatly reduces the labor intensity of the operator.
● 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.
● The high-pressure water pump, key hydraulic components, electrical components and high-pressure nozzles are imported from well-known brands.
