The high pressure cleaning vehicle is modified on the basis of the second type of original chassis, and the upper part is a tank body, and a high pressure water pump is configured to work. The width of jet cleaning is 2.5m-3.5m, which can be arbitrarily controlled. When the telescopic boom shrinks, it can achieve the dual-flow enhanced cleaning, which is suitable for cleaning the city's roads and squares; the left and right corner sprays are suitable for cleaning road edges. , fence barriers, sidewalks, etc. The principle of the high-pressure road washing vehicle: The water pump is driven by the original hydraulic system of the carrying vehicle. HPW high-pressure water pump is used as a water source, and with various special high-efficiency nozzles, KPL series cleaning equipment has powerful cleaning capabilities. Due to the very high output pressure, the unit wash area of ​​the KPL series equipment is very low in water consumption. Several high-pressure nozzles work side by side to not only thoroughly clean the road, but also to sweep the trash and ash soil to the desired location like a bulldozer. Due to the small amount of water used, the road surface will dry quickly after being clear. What is more worth mentioning is that since the water consumption per unit area is small, only a small vehicle can be used to complete a large area of ​​street cleaning, thereby reducing the pressure on crowded urban traffic. First, the performance characteristics of high-pressure road cleaning vehicles are as follows: 1. Automatic control of the cleaning process. The KPL street cleaning system reliably and simply cleans trash and ash soil mud under the fully automatic control and cooperation of supporting wheels and rotating nozzles. 2. High pressure, water saving When the water pressure reaches 90-200 bar, the water consumption per square meter will be less than 1 liter. In this way, a large area of ​​streets can be cleaned with a small water tank, which saves water and energy, reduces the number of water additions, and improves work efficiency. In addition, such a small amount of water will not form a stream on the ground, and the road surface can dry quickly. Second, the high pressure road cleaning car features and advantages 1. The cleaning width of the water jet rack is 2.3m-3.5m, which can be arbitrarily controlled. When the telescopic boom shrinks, it can realize double-flow enhanced cleaning and is suitable for cleaning urban roads and squares; 2. Spray system, can spray dust, adjust air humidity and spray air disinfectant; 3. Low-pressure flushing and water cooling; with independent forward (water), after-spray device; green irrigation and auxiliary fire fighting function. 4. Compared with human cleaning, nearly 4 tons of water is saved per kilometer. In the past, 40 people per kilometer of pedestrian walkway needed to be completed, which took 5 hours to complete, and only 3 persons were required to clean the sidewalk cleaning vehicle within 1 hour. Third, the operation of attention 1. Requirements for water When the high-pressure cleaning vehicle uses a river ditch or a pond as a water source, pay attention that all the ends of the suction pipe do not enter the water. In order to avoid inhaling stones or more sand and drift debris, the suction pipe end is generally provided with a filtering device, and it is forbidden to remove the filtering device during the water absorption. If the water source is shallow, it is necessary to dig up the water absorption area in advance so as to ensure that it does not contain impurities and air. 2. Add water diversion Every time the centrifugal pump absorbs water, a certain amount of water must be added to the pump. After the addition, the water inlet must be closed. When the self-priming pump is used for the first time, it is necessary to add water, and it is unnecessary to add water afterwards. 3. The inlet pipe must be vacuumed The water inlet system must maintain a certain degree of vacuum before it can suck water into the tank. The inlet pipe system must be sealed reliably, the hose can not be damaged, the hard pipe can not have cracks, otherwise it will have a phenomenon of air leakage, which will result in the situation that it cannot suck water. 4. Parking gear Before the high-pressure cleaning vehicle is absorbing water or before the operation, the power take-off device must be stopped while parking. 5. Winter water release Before the advent of winter, the water in the pumps and pipes should be vented to prevent freezing. The northern part of the country is generally no longer under construction during the severe winter. Therefore, after the construction is completed, the water in the pump and the water pipe will be drained immediately to prevent future problems. 6. Regular discharge The storage tank of the high-pressure cleaning vehicle is provided with a sewage pipe, and the inlet of the pipe is the lowest point of the water tank. After a period of use, the discharge pipe switch should be opened periodically to remove the accumulated debris from the tank until the water becomes clear. Fourth, the maintenance steps Before cleaning, the body surface temperature should be cooled below 60°C, and the ambient temperature should be maintained at 0-40°C. The water gun is more than 15 cm away from the body paint surface. The order of flushing is from the roof to both sides. When rinsing the grille part in front of the car, misty water flow should be used, and the water column should not be flushed against the fins of the water tank or condenser. If the plastic arch cover is installed at the mudguard, it should be removed and cleaned, and the mudguard should be thoroughly cleaned. , Fender inside. 1. It is to clear away the remains of the car body. You can use the all-round descaling water to wipe with a clean cotton cloth. Then wring out the dustless cotton cloth with the car wash liquid, dry the car paint along the direction perpendicular to the car's driving direction. Car wash on the surface. Finally, rinse the car wash thoroughly with plenty of clean water, and dry it with a synthetic sheepskin towel. Wipe dry to achieve the whole car water-free traces, glass stainless 2. High-pressure water gun cleaning is to use the high-pressure water gun to wash away the dirt that is contaminated on the surface of the car body from top to bottom, then rinse the back of the car body, and finally wash the lower part of the car. This step is to pay attention to the need to fully flush the chassis and thoroughly clean the edges, bends, fenders, etc. Particular care should be taken to thoroughly clean the sand and dirt from the wheels, brake discs, fenders, front grilles, door frames, and skirts. 3 is to wipe, use a car wash sponge shampoo car shampoo, wipe the body again, if contaminated objects are not easy to remove, you can repeatedly wipe, pay attention to wipe the body up and down the sponge to be used separately, so as not to scratch the body under the sand paint body paint. Then rinse with high-pressure water, in particular, to clean the seams at the car seams, foam at the corners, etc. 4. Apply liquid to spill the shampoo car wash on the body. There are two methods, one is to use multi-functional high-pressure foam washing machine, spray evenly, to the upper and lower regularly shaking nozzle; the second is manual preparation, that is, according to a certain proportion of shampoo car wash liquid, do not use washing powder, soapy water, Dewaxing detergent.
