Sewage suction vehicles

The sewage suction vehicles is developed by Zoomlion for maintenance of municipal facilities, applicable to cleaning operation of rainwater well, sedimentation well and ditches and suction of sewage and sediment, transport and discharge for oil refining industry, iron and steel industry, chemical industry, real estate management and environmental sanitation industry.


Working principle:

• sewage suction: the sewage tank is vacuumized by vacuum pump driven by chassis engine; when the vacuum hose is inserted into the sludge, the sludge is sucked into the sewage tank ; the sewage is filtered and then flows to the sewer while the sludge is left in the sewage tank; the sludge is sent to specified location and discharge;

• sludge removal: the vacuum pump produces vacuum and high speed air flow in the vacuum hose; when the vacuum hose is inserted into hard sludge containing less water or when aim the vacuum hose at sand and garbage to bring the sand and garbage into the sewage tank via teh high speed air flow.
