DFAC 6CBM Vacuum Tank Vehicle

The cleaning and sewage-absorbing vehicle has the functions of Flushing, dredging, sewage-absorbing and anti-discharging. The role of the sewage suction truck: collection, transfer cleaning transport sludge, sewage, avoid secondary pollution of the new sanitation vehicles, sewage suction truck can self-absorption self-discharge, work fast, large capacity, convenient transportation, it is suitable for collecting and transporting liquid substances such as feces, mud and crude oil. The working principle of the sewage suction truck: as the dung suction hose is always immersed in the liquid surface, the air in the dung tank becomes thinner and thinner after being sucked because it can not be replenished, thus causing the pressure in the tank to be lower than the atmospheric pressure, the fecal liquid is used under atmospheric pressure and enters the container through the fecal suction hose. Or, because the siphon is close to the bottom of the tank, air is continuously discharged into the dung tank and compressed because there is no way out of the tank, so that the pressure in the tank is higher than the atmospheric pressure, and the Dung liquid, under the action of the Compressed air, passes through the siphon, the dung suction hose is discharged from the tank.
