Sewage suction truck VS fecal suction truck

A suction truck is a specialized vehicle mainly used for cleaning and cleaning in environments such as septic tanks, sewage ditches, and sewers. The key components of both sewage suction trucks and fecal suction trucks are vacuum suction pumps, which use the pressure difference generated by the operation of the vacuum pump to suction flowable waste. However, the sewage suction truck adopts a circular tank body with high strength and high vacuum degree, ensuring that the tank body is not flattened during operation. The back cover of the tank body can be opened by hydraulic pressure, and the entire tank body can be lifted or lowered by hydraulic pressure. The structure of the suction truck is relatively simple, using an elliptical tank body that requires less suction than the suction truck. The rear head seal cannot be opened, and the pressure generated by the vacuum pump is used for discharge or self discharge. This is the difference between a sewage truck and a sewage truck.

A suction truck is a new type of environmental sanitation vehicle that integrates collection, transportation, transfer, cleaning, and prevention of secondary pollution. The suction truck has a large capacity and can achieve self suction and self discharge, with high work efficiency. It is suitable for the transportation of substances such as feces, mud, and crude oil.

The sewage suction truck adopts high-quality vacuum pumps with high suction power and long suction range, which are particularly suitable for the suction, transportation, and discharge of sediment in sewers, especially mud, silt, stones, bricks, and other objects.

The main power source for the suction pump in the sewage truck comes from the engine, which is transmitted to the vacuum pump through the gearbox, power take-off, and transmission shaft. Due to the fact that the suction hose is always immersed in the dirt, when the vacuum pump extracts the air from the sealed tank, the air inside the tank becomes increasingly thin due to the lack of replenishment, creating negative pressure. The dirt enters the tank through the suction hose under atmospheric pressure. When discharging pollutants, the vacuum pump injects atmospheric pressure from outside the tank into the tank, and uses the air pressure to discharge the pollutants from outside the tank.

Characteristics of vacuum pump:

1. The vacuum degree is relatively high;

2. Can extract dusty gases, condensable gases, and steam water mixtures;

3. Equipped with a pump stop and oil return prevention device, making it easy to restart;

4. The exhaust port is equipped with an oil mist trap to avoid environmental pollution;

5. Can maintain high rotational speed even under low pressure.
