How vacuum trucks mainly work?

Because the feces hose is always immersed in the liquid surface cloth, the air in the feces tank is pumped, because it can not be replenished and more and more thin, resulting in the pressure in the tank is lower than the atmospheric pressure, dung liquid is used under atmospheric pressure, through the suction hose into the tank, Or because the siphon pipe is close to the bottom of the tank, the air is constantly discharged into the tank, because it has no way out and is compressed, resulting in the pressure in the tank is higher than the atmospheric pressure, feces liquid is under the action of compressed air, through a siphon tube, suction hose discharged from the tank. Vacuum trucks can be self-absorbing and self-draining. It has the advantages of fast working speed, large capacity, and convenient transportation. Transport of feces, mud, crude oil, and other liquid substances In the existing technology, sewage vehicles use the vacuum pump of sewage vehicles to empty the pump body, especially suitable for sewers, especially sludge, sludge, stone extraction, transport, and discharge of large brick objects. During the suction process, the suction hose is always immersed in the liquid surface. When the air in the sludge tank is inhaled, it becomes thinner and thinner because it cannot be replenished, so the pressure in the tank is lower than the atmospheric pressure, and the sludge is under pressure in the atmosphere, which enters the sludge tank through the sludge. Absorbent pipes. Or because the siphon is close to the bottom of the tank and the air is constantly being discharged into the sludge tank, the air is compressed because there is no way out, causing the pressure in the tank to be higher than the atmospheric pressure. Under the action of compressed air, sludge is discharged through siphons and suction pipes outside the tank. 

 

The main part size of the vacuum truck

In vacuum trucks in general, the pump tubes used are typically between 1 and 4 inches (2.5 to 10 cm) in diameter, but this may also vary depending on the job. 

 

Vacuum trucks work mainly by pumps

The pump on the vacuum truck can be operated by the power output shaft (PTO) of the vehicle engine or by a special motor. The power output shaft is usually a flower key drive shaft connected to the vehicle drive train. When the truck is stationary, the power can be cut off from the wheels and transferred to the power output shaft. This driveshaft can power a variety of different projects, such as pumps on vacuum trucks. The power output shaft on a vacuum truck can be used to drive the pump with leather, although hydraulics are sometimes used, if the vacuum unit is mounted on a trailer or the base of a pickup truck, it may not be feasible to use PTO in this case, usually using a small gasoline engine to drive the vacuum pump. This is sometimes referred to as a small engine and can also refer to a small gas engine used to start a large diesel engine. 

 

Other accessories for vacuum trucks

For easy pumping, vacuum trucks are usually equipped with some type of lifting arm. The pump tube is secured to the boom, making it easier to place it on materials that need to be pumped. This is often helpful when vacuuming septic tanks in backyards or drilling sites, as equipment or debris prevents the truck from approaching.
