The working principle, functions, and advantages of a three wheeled fecal suction truck

The three wheeled suction truck is mainly used as a specialized vehicle for cleaning and cleaning in environments such 

as septic tanks, sewage ditches, and sewers. Along with sprinkler trucks and garbage trucks, it is also known as one of 

the three major sanitation vehicles and does not need to pay purchase tax. Below is a brief introduction to the working 

principle, functions, and advantages of a three wheeled fecal suction truck.

working principle:

To operate a vacuum pump, it is necessary to first understand its working principle, in which the source of power and 

stability considerations are particularly important. The power of the vacuum pump comes from the chassis engine. The 

engine is transmitted to the vacuum pump through the gearbox, power take-off, and drive shaft. During the suction 

operation, the vacuum pump extracts air from the sealed tank to create negative pressure, and uses the atmospheric 

pressure outside the tank to press the dirt into the tank through the suction pipe. When discharging, the vacuum pump 

will inject atmospheric pressure from outside the tank into the tank and use air pressure to discharge the pollutants 

outside the tank (the continuous working time of the vacuum pump generally does not exceed 30 minutes).

Function description of fecal suction truck:

Vacuum suction truck configuration: The dedicated part consists of a power take-off, transmission shaft, vacuum 

suction pump, water gas separator, oil gas separator, multi way directional valve, manure tank, manure discharge 

valve, manure suction gun, clean water tank, manure observation window, vacuum pressure gauge, pipeline system, 

etc. This product is used for suctioning feces, sewage, sludge, and liquids mixed with small suspended solids. It has the 

characteristics of high suction efficiency, self suction, self discharge, and direct irrigation. It is widely used in 

environmental sanitation, municipal, agricultural, chemical, industrial and mining enterprises, and property 

communities in large, medium, and small towns. The vacuum suction pump can self suction and discharge.

Advantages:

The three wheeled fecal suction truck has a small volume, and although its load-bearing capacity is relatively weak, 

its flexibility is important. It can be used in small factories, rural areas, urban areas, etc., and some small and 

medium-sized enterprises can reduce their huge car purchase costs. Construction truck is a specialized vehicle mainly 

used for cleaning and sanitation work in environments such as septic tanks, sewage ditches, and sewers. It is one of 

the three major sanitation vehicles, along with sprinkler trucks and garbage trucks.
