What is the difference between a sewage suction truck and a fecal suction truck?

The most intuitive difference between a sewage suction truck and a fecal suction truck is:

The rear door of the sewage suction truck can be opened 90 degrees, and the sludge can be dumped out by itself.

The fecal suction truck has no back door, only a fecal opening.
Due to the different substances shipped, the functions vary greatly, and of course the prices are also different.

Common point: both sewage suction trucks and fecal suction trucks are sanitation vehicles, and the key components are vacuum pumps. Both can be used to clean manure and sewage sludge.

Differences: Because of the differences in the structure of the two vehicles, the specific uses and prices are very different.

The sewage suction truck adopts a round tank body, the rear can be opened, and the tank body is lifted by a hydraulic cylinder for sewage discharge.

The structure of the fecal suction truck is relatively simple, using an oval tank body, the rear head is sealed, and the pressure generated by the vacuum pump is used to discharge the sewage.

The above is the biggest difference in the structure of the sewage suction truck and the fecal suction truck, which leads to the following differences:

1. Affected by the structure and shape of the tank, the vacuum degree and suction of the fecal suction truck are not as large as those of the sewage suction truck.

2. The sewage suction truck uses the pressure difference of the vacuum pump to discharge the sewage. Due to the position of the sewage outlet, the larger stones cannot be discharged and cannot be used for the dredging work of the larger objects.

3. The sewage suction truck adopts a hydraulic top-opening sewage discharge structure, and the sewage discharge efficiency and sewage discharge effect are better.

4. Influenced by domestic usage habits, users in the north use more sewage suction vehicles, and users in the south use fecal suction vehicles more commonly.

Generally speaking, the performance of the sewage suction truck is better than that of the fecal suction truck, and it is easy to use and has a low failure rate. However, due to the difference in structure and components, the cost of the sewage suction truck is much higher than that of the sewage suction truck. When choosing, you need to consult the manufacturer of the sewage suction truck in detail according to the specific use.
