Dongfeng Tianjin 15CBM Cleaning and Sewage Suction Truck

A vacuum truck refers to a specialized vehicle that utilizes a high - power vacuum system to suck, collect, and transport liquid waste, sludge, sewage, and other viscous or solid - liquid mixed pollutants. It plays a crucial role in environmental sanitation, municipal engineering, and industrial waste treatment, significantly improving the efficiency and cleanliness of pollutant cleanup operations, while avoiding secondary pollution to the surrounding environment.

Working principle:

After the vacuum pump is started, it creates a strong negative pressure inside the sealed sewage tank. Through the suction hose connected to the tank, the vehicle is positioned at the pollutant collection point, and the hose is inserted into the sewage, sludge, or other waste. Under the action of the negative pressure, the waste is rapidly sucked into the sealed tank. During the suction process, the filter device inside the tank prevents large solid impurities from entering the vacuum pump and damaging the equipment. After the tank is filled with waste, the vacuum pump is stopped, and the vehicle drives to the designated disposal site. Then, by opening the discharge valve at the bottom or rear of the tank and using the pressure inside the tank (which can be increased by a compression device if necessary) or gravity, the collected waste is discharged into the corresponding treatment facilities, completing the entire process of waste collection and transportation.
