The actual function difference between vacuum suction sewage truck and fecal suction truck

Fecal suction truck

Vacuum sewage suction truck and fecal suction truck are the two most commonly used special vehicles in the sanitation industry. Although these two models have only one word difference in their names, are there any differences between them? Is it just that the name is different? Below, Chengli Special Automobile Co., Ltd will explain in detail the main functional differences between the vacuum sewage suction truck and the fecal suction truck and the model technology.

 

1. The shape and process comparison of vacuum sewage suction truck and fecal suction truck:

 

In terms of the shape of the tank, the vacuum sewage suction truck adopts a circular tank body, and the fecal suction truck adopts an oval turtleback design. Although the two kinds of tank bodies are different in shape, they both have the advantages of good stability and not easy to deform;

 

Both the vacuum sewage suction truck and the fecal suction truck are equipped with 4 anti-wave partitions, and the circular manholes are arranged in a staggered arrangement between the partitions. This makes the vacuum suction truck and the fecal suction truck liquid to the tank body during operation. The internal impact is greatly reduced, making the vehicle more maneuverable.

 

The tank body of the vacuum sewage suction truck is fixed on a special frame, and the tank feet are designed according to the structure of the front high and the low rear. This makes the sewage outlet at the rear of the tank body located at the lowest point after the tank body is installed, and the sewage inside the tank body is discharged more thoroughly . Observation hole seats are set on the front and rear heads of the tank, and transparent polyethylene plates are installed and fixed to observe the water level of the sewage inside the tank at any time.

 

Both sides of the upper part of the vacuum sewage suction truck and the fecal suction truck are welded with safety guardrails, which play a role of safety protection when the staff walks on the top. A reinforcing plate is welded on the inner wall of the cylinder at the insertion end of the suction pipe inside the tank to prevent the corrosive liquid from impacting the tank for a long time and causing premature damage to the tank.

 

The rear cover of the tank body of the vacuum sewage suction truck can be opened, and the entire tank body can be hydraulically lifted or lowered, which makes the vacuum sewage suction truck more thorough. The back cover of the tank body of the suction truck cannot be opened, and the sewage is mainly discharged through the vacuum pressure difference, and the sewage discharge capacity is weaker than that of the vacuum suction truck.

 

2. Comparison of vacuum sewage suction truck and vacuum pump of fecal suction truck

 

The vacuum sewage suction pump equipped with the vacuum sewage suction truck has a higher vacuum degree and a stronger suction force than the fecal suction truck pump. The vacuum sewage suction truck can absorb gravel, small bricks, and sludge. The fecal suction truck is mainly used for cleaning and transporting sewage , Feces, sludge and liquid mixed with small suspended debris.

 

From the above two main aspects, it can be seen that the operating range of the suction truck is much smaller than that of the suction truck due to the tank design and the configuration of the suction pump. Simply put, the vacuum suction truck has all the functions of the suction truck, so Although the price of vacuum sewage suction trucks is higher than that of fecal suction trucks from the perspective of one-time investment, in the long run, it is wise to choose vacuum sewage suction trucks for users who require high suction and sewage capacity. Therefore, when choosing to unblock the vehicle, communicate with the sales staff of the manufacturer and learn more about the configuration and purpose of the vehicle. This will enable you to buy the most practical vacuum suction truck or fecal suction truck. Effectively avoid the waste of low-requirement and high-configuration vehicles, and avoid the impact of high-requirement and low-configuration on later use.
