Description of HOWO sewage pump truck
Chassis and Powertrain
✦ Heavy Duty Chassis: Utilizes a Sinotruk 6×4 dual axle chassis, paired with a 10 speed gearbox and pneumatic brakes, offering excellent load bearing capacity and strong stability in complex road conditions, meeting the requirements for long distance transport under full load.
✦ High Power Engine: The vehicle is equipped with a 400 horsepower water cooled turbocharged diesel engine, providing ample power to ensure stable driving speeds and provide stable power output for the vacuum pump.
Tank
✦ Tank Material: The tank is made of Q235 carbon steel, which is corrosion resistant and wear resistant, it can hold sewage, sludge, and industrial wastewater. The sealed structure prevents leakage during transportation.
✦ Large Capacity Design: This tank has a volume of 20CBM and is equipped with a hydraulic lifting structure. During unloading, the tank tilts and unloads itself, eliminating the need for manual cleaning and improving transfer efficiency.
Vacuum Suction System
✦ High Efficiency Suction: With the help of a pressure difference created by a vacuum negative pressure of up to 93%, the vehicle can quickly extract solid liquid mixtures such as sludge; at the same time, its vacuum pump works stably and has a good suction capacity for various viscous sludge.
✦ Operating Capacity: The vehicle's vertical suction lift exceeds 9 meters and its horizontal suction lift reaches 50 meters, with powerful suction capable of meeting the high efficiency pumping needs of deep wells and remote locations.

Working principle of HOWO vacuum tanker truck
▶ Vacuum Generation: A rotary vane pump or liquid ring pump extracts air from the sealed tank. ▶ Pressure Differential: The pressure inside the tank is lower than the atmospheric pressure outside. ▶ Material collection: External pressure forces waste into the tank through a suction pipe. ▶ Safety System: Float and shut-off valves prevent overflow and protect the pump. ▶ Discharge: Material is discharged from the tank by gravity or pressurization.
Application scenarios
Applicable Operating Scenarios:
Municipal Sanitation: Pumping and removing sludge and waste from urban sewers, septic tanks, and rainwater wells. Residential Property Management: Regular cleaning of septic tanks and grease traps in residential areas. Industrial and Mining Areas: Transfer of wastewater from factory wastewater ponds, sedimentation tanks, and mud/waste liquid. Construction Sites: Cleaning of construction mud, water accumulation in foundation pits, and sludge.

FAQ
Q: Why can't the vacuum truck suck up the sludge?
A: ① Air leakage in the pipeline, damage to the suction hose, or negative pressure leakage; ② Water accumulation in the water air separator or blockage of the antioverflow valve; ③ Insufficient oil or wear in the vacuum pump. Repairing the pipeline seals and cleaning the filter element will solve the problem.
Q: How to maintain a vacuum pump on a daily basis?
A: Regularly change the special lubricating oil for vacuum pumps; drain the water accumulated in the separator after each operation; prevent sewage from flowing back into the pump body, and greatly extend the service life of the pump.
Q: Is it okay to work outdoors in the rain?
A: Yes, the entire vehicle's electronic control system and pump body are waterproofed, but it is strictly forbidden to immerse the suction pipe in deep water and to prevent rainwater from flowing back into the tank.
Q: Do hot/rainy tropical regions require special modifications?
A: For tropical regions, optional features include a high temperature resistant vacuum pump, a thickened cooling system, and waterproofing of all vehicle wiring. For cold regions, low temperature engine oil and a preheating device are provide.
