Vacuum Sewage Truck (commonly known as Sewage suction truck) is a special sanitation vehicle equipped with vacuum pump, used to suck, transport and discharge sewage, sludge, mud and wastewater.
A Vacuum Sewage Truck is a dedicated municipal sanitation vehicle designed with a high-performance vacuum pumping system. It creates negative pressure inside the sealed tank to suction sewage, sludge, slurry, sewage waste and other liquid-solid mixtures from sewers, septic tanks, drainage pipes and sewage pits. The collected waste is stored in the tank and transported to designated treatment areas for unloading. This vehicle is widely applied in urban sanitation, environmental protection, municipal engineering and rural sewage treatment.
Body Structure Description
Its storage tank is constructed with thickened high-strength carbon steel integrated stamping and welding structure, adopting integral sealing and pressure-resistant design to bear negative pressure suction and hydraulic discharging
Advantages:
1.High working efficiency:Adopts vacuum negative pressure suction mode, with fast suction and discharge speed, which can quickly clean sewage, sludge and blockages.
2.Wide application range:Suitable for sewer, septic tank, sewage pit and other scenarios, capable of handling various liquid and solid mixed wastes.
3.Good sealing & environmental protection:The fully sealed tank avoids leakage and odor overflow, reducing secondary pollution.
4.Flexible & labor-saving:Integrates suction, storage and transportation, reducing manual operation and lowering labor costs.
5.Stable performance:Equipped with mature vacuum and hydraulic systems, with stable operation and long service life.
