Pollution absorbing vehicles: analysis of the hardcore technology of urban "cleaners"

In the hidden corners of urban underground pipelines, septic tanks, sewers, and rainwater wells, there is a type of "cleaner" who accompanies sludge and sewage all year round, but silently guards urban hygiene - it is the sewage truck. Today, we unveil the technological veil of this "environmental sanitation artifact" from core components, working scenarios to operating principles。

The powerful function of the sewage suction truck relies on the combination of precision designed components:

Vacuum suction pump: As the "heart", it generates negative pressure through high-speed rotation, with a maximum vacuum degree of -0.08MPa, far exceeding ordinary suction trucks. Equipped with an anti overflow valve design to avoid sewage backflow during operation.

Pressure tank body: It adopts a circular sealing structure formed by one-time die-casting, which is resistant to high pressure and can be discharged in a rear opening manner. The tank is equipped with a visual pollution window (connector) to monitor the loading capacity in real-time.

Hydraulic system:

Drive the rear cover of the tank to open and dump, and the double top hydraulic rod can easily dump 10 tons of waste.

Intelligent control system:

The four-way valve accurately switches the suction and discharge modes, the water gas separator filters harmful gases, and the pressure gauge monitors the status inside the tank in real time
