Sewage suction trucks and fecal suction trucks, as special vehicles for sanitation, are distinguished by function: sewage suction trucks are new types of sanitation vehicles that collect and transfer sludge and sewage to avoid secondary pollution.
The fecal suction truck is mainly used in special vehicles for cleaning and cleaning in septic tanks, sewage ditches and sewers. Although the two models differ only by one word, they have completely different characteristics and functions .
Appearance : the shape of the tank is different
From the appearance and production process, the tank used by the sewage suction truck is a round tank, while the tank used by the sewage suction truck is designed as an oval turtle-back tank; the two models are in the tank body. There are four anti-wave partitions inside, which can avoid the unstable factors caused by the shaking of the liquid in the pipe due to the movement of the vehicle during transportation; the tank foot of the sewage suction truck is designed with a high and thick bottom. , So as to facilitate the convenience in the process of use.
In addition, the upper part of the tank body of the fecal suction truck is designed with a safety guardrail, which can protect the staff during walking. The rear of the tank body of the sewage suction truck is designed with a rear cover, which can be opened and closed when needed. The rear cover of the tank body of the suction truck cannot be opened. Therefore, the suction truck is relatively better than the sewage suction truck. The car’s sewage capacity is weaker.
Functional configuration : vacuum pump differentiation
Secondly, from the perspective of the vacuum pumps of the two special vehicles, the vacuum pump configuration of the sewage suction truck is higher than that of the fecal suction truck.
In the process of sucking the sewage, small bricks, broken stones and some sludge can be sucked away, but The fecal suction truck cannot clean these things, and the fecal suction truck can only extract liquid with suspended matter .
Affected by the structure and shape of the tank, the vacuum and suction power of the suction truck is not as large as that of the sewage suction truck. The suction range of the suction truck is ≥ 7m , and the suction range of the sewage suction truck is ≥ 10m.
The tank body of the suction truck is fixed on the car and can only be discharged by the pressure difference of the vacuum pump or the pipeline is self-draining; the rear of the tank body of the sewage suction truck can be opened, and the liquid lifting function is used. it is good.
Application difference : sewage suction truck is more widely used than fecal suction truck
The sewage suction truck can complete all the tasks of the fecal suction truck, but some tasks of the fecal suction truck cannot be completed.
Affected by usage habits, users in the north use sewage suction trucks more, and users in the south generally use sewage suction trucks . In actual use, the performance of the sewage suction truck is far better than that of the suction truck, and its operating range also exceeds the operating range of the suction truck, so when choosing a sewage vehicle, you should make the necessary choices according to your needs.
