Functional characteristics and maintenance points of Chengli cleaning and suction truck
Functional characteristics of cleaning and suction trucks：High pressure cleaning and suction trucks have high mission efficiency and strong dredging capabilities. They are a powerful tool for sewer dredging and a good helper for municipal sanitation workers. Make environmental sanitation operations more animalistic and intelligent.
Cleaning and maintenance of sewage suction vehicles; Before cleaning, the surface temperature of the vehicle body should be cooled to below 60 ℃, and the ambient temperature should be maintained between 0-40 ℃. The water gun should be at least 15 centimeters away from the vehicle's paint surface. The order of flushing is from the roof to both ends. When flushing the grille area in front of the car, a misty water flow should be used instead of using a water column to flush against the radiator or condenser fins. If a plastic arch cover is installed at the mudguard, it should be removed and cleaned thoroughly, and the inside of the mudguard and fender should be thoroughly cleaned.
● It is to clean the stubborn traces left on the car body. It can be done by using a universal descaling water and a dust-free cotton cloth to stop careful cleaning, then wringing out the dust-free cotton cloth dipped in car wash fluid, and wiping off the car wash fluid on the paint surface of the car body in a direction perpendicular to the car's movement. At the beginning, rinse the car wash thoroughly with sufficient water and promptly dry the water with a sheepskin towel. Wipe dry until there are no water stains or stained glass on the entire vehicle
●High pressure water gun cleaning is to use a high-pressure water gun to wash away the mud and sand infected on the surface of the vehicle from top to bottom, then rinse the rear of the vehicle, and start washing the lower part of the car. During this process, it is important to wash the chassis one by one and thoroughly clean the edges, bends, mudguards, and other areas. Especially, the wheels, brake discs, fenders, front grille, door frames, and skirts should be thoroughly washed clean of mud, dirt, and debris.
●It is scrubbing. Dip a car wash sponge into shampoo and car wash solution, wipe the car body once. If the infection is not easy to remove, repeat the scrubbing. Pay attention to separating the sponges on the car body to avoid sand particles on the lower part of the car body scratching the paint surface. Then wash with high-pressure spray, especially the foam and other residues at the joints and corners of the car.
●Pour shampoo and car wash solution onto the vehicle body. There are two methods. One is to use a multi-function high-pressure foam cleaner, which should be sprayed evenly and shake the nozzle regularly up and down; The second is artisanal manufacturing, which means producing shampoo and car wash liquid in a certain proportion, and not using laundry detergent, soap water, or dewaxing detergent. Before the arrival of summer, the water pump and pipes should be emptied to prevent freezing and cracking. In the harsh winter in southern China, construction is no longer carried out. Therefore, after the construction is completed, the water pump and pipes are immediately emptied to prevent future problems. Cleaning the car requires constant drainage, and the water storage tank is equipped with a drainage pipe whose outlet is the lowest point of the tank. After a period of use, the drain switch should be turned on regularly to clean the accumulated debris in the tank until the water becomes clear.
