5.Working Principle of Product Operation
6.Common accessory images are as follows
7.The following are the after-sales requirements for the product
(1)Maintain the appropriate rotation speed of the oil pump vacuum pump; The rotation speed of the vacuum pump is too high, which intensifies the heating of the rotor; If the speed is too low, it will cause additional impacts on the shipping machine and components, affecting their lifespan. To achieve the appropriate working speed, please adjust the optimal position of the hand throttle according to the pump type in advance.
(2)Self dumping and flipping of cans on flat ground; Dumping cans on sloping roads can cause distortion and deformation of various components, leading to malfunctions, and may also cause rollover accidents. It is also not allowed to top a full can.
(3)When self dumping and flipping the tank, first open the tank body and then the tank door; Before unloading the mud from a self dumping tank, the locking bolt should be loosened first, and the rear tank door should be raised to the required angle. When the tank is fully loaded, it is prohibited to lift the tank when the rear tank door is closed, otherwise there is a risk of overturning.
(4)When the oil pump and vacuum pump take power, the engine idles and the clutch pedal is fully pressed. After turning on the power take-off switch, slowly release the clutch pedal.
(5)When the car is in motion, the high-pressure pump and oil pump are in a stopped state
(6)The vehicle is not allowed to inhale materials larger than the diameter of the rubber hose and transport waste oil and hazardous materials.
(7)When entering the bottom of the self dumping and flipping tank for lifting or maintenance, support rods and safety blocks must be used.
8.Precautions for suction and maintenance
(1)Add diesel engine oil to the suction pump and oil gas separator, and replace the oil between 30 and 40 vehicles. For the second time, if you need more than 40 cars, you can replace them. If there is less oil in the future, you can add oil and change the oil every 3-6 months. The hydraulic oil in the hydraulic system is replaced once a quarter.
(2)If foreign objects and water enter the oil and gas separator, the oil must be replaced. The oil in the oil and gas separator must not exceed the observation hole position or be lower than the three-way position of the oil pipe, otherwise it will damage the vacuum pump.
(3)When the outdoor temperature is below 0 degrees Celsius, use antifreeze engine oil. Use diesel engine oil between 0 and 10 degrees Celsius. If the temperature is above 10 degrees Celsius, replace the closed gear engine oil and check to ensure smooth oil flow.
(4)If the vacuum degree of the new pump is not high during the first use, the reason is that there is no oil in the new pump or there is too little oil, and the pump cannot generate a vacuum during operation. Oil cannot be sucked into the pump from the oil and gas separator. The solution is to add 1-2 liters of engine oil to the new pump. If there is oil in the pump, a vacuum can be generated, and the oil can be sucked into the pump from the oil and gas separator, thereby generating a vacuum.
(5)If the suction truck operates carelessly during operation and sucks sewage too much, it will suck the sewage into the vacuum pump and install it in the water vapor separation, oil vapor separation, and pipeline system at the back, causing the entire system to be blocked by dirt. The entire system will not be able to form a vacuum, and in severe cases, it will damage the vacuum pump. In this case, the suction pipeline system (including the four-way valve and water vapor separator) should be thoroughly disassembled and cleaned, the oil and gas separator, the oil pipe tee, and the inlet and return oil pipes should be cleaned, the contaminated oil should be replaced, and the pollutants in the vacuum pump should be carefully removed.
(6)If the oil is not extracted after cleaning and changing, check whether the balls of the water vapor separator and the anti overflow valve are in the corresponding positions (both the anti overflow valve and the water vapor separator should be at the bottom, and the anti overflow valve is only for protective purposes, not 100% effective. If the air bubble in the tank is too large or there is foreign object on the anti overflow valve ball, it will cause the anti overflow valve to be ineffective). After using the car for a period of time, it is necessary to check whether the universal joint screws are loose and tighten or replace them (the transmission shaft connecting the vacuum pump and power take-off is not within the scope of chassis service as it belongs to the upper part, and users need to regularly check and tighten it).

FAQ
1. What makes the dual high/low pressure water system a significant advantage?
The independent dual-pressure system provides exceptional versatility. The high-pressure mode is perfect for powerful sewer pipe dredging and cutting through tough blockages, while the low-pressure mode is ideal for efficient, wider-area cleaning of surfaces and delicate infrastructure. This allows operators to select the optimal setting for each task, improving results and conserving water and energy.
2. What types of solid waste can it effectively handle in sewer systems?
Our truck is engineered to extract a wide range of solid and semi-solid waste. Its powerful vacuum system and robust design can efficiently suck up challenging debris commonly found in sewers, including mud, silt, stones, bricks, and other deposited solids, making it highly effective for comprehensive pipeline restoration.
3. How does the tank's construction ensure long-term durability?
The tank is built for longevity using fully automatic welding with single-sided welding and double-sided forming, ensuring superior strength and leak-proof integrity. It undergoes a sandblasting and spraying process that creates a highly corrosion-resistant and acid/alkali-resistant coating, protecting it from the harsh chemicals and abrasive materials encountered in daily operations.
4. What is the benefit of the "beef tendon" pipes used on the truck?
The sturdy and durable beef tendon pipes are specifically chosen for their exceptional abrasion resistance, flexibility, and strength. They withstand the suction of abrasive materials like sand and stones and resist cracking under high pressure or in extreme temperatures, significantly reducing maintenance downtime and replacement costs.
5. What does "high vacuum degree" mean for operational performance?
A high vacuum degree refers to the powerful suction force generated by the system. This high level of vacuum allows the truck to lift heavy, wet sludge and materials from significant depths, dramatically increasing the speed and completeness of waste extraction, which translates to faster job completion and more thorough cleaning.
6. Is the 3-cubic-meter capacity suitable for large-scale municipal jobs?
Yes, the 3-cubic-meter tonnage offers an optimal balance. It provides substantial waste-holding capacity for extended work cycles—such as cleaning multiple residential sewer lines or a long stretch of urban drainage—before needing to offload, while maintaining a manageable vehicle size for maneuverability in tight urban and residential areas.
7. How does this truck improve efficiency in sewer and drain maintenance?
Its high-efficiency design combines powerful suction for rapid waste removal with effective high-pressure dredging to break apart blockages. This integrated approach allows a single vehicle and operator to tackle the entire job—from loosening compacted debris to fully extracting it—streamlining operations and reducing time on site.
8. Can it be used for applications beyond standard sewer cleaning?
Absolutely. Its wider application range includes industrial tank cleaning, spill recovery, storm drain maintenance, cleaning sedimentation ponds, and handling slurry or wastewater in agricultural or construction settings. The combination of robust suction and adjustable pressure washing makes it a highly versatile industrial and municipal asset.
9. What safety features are integrated into the system?
Key safety features include vacuum relief valves to prevent over-pressurization, fail-safes on the hydraulic systems, and a secure, stable chassis mounting for all equipment. The corrosion-resistant tank construction also ensures structural safety when handling reactive substances, protecting both the operator and the asset.
10. What kind of after-sales support and warranty is provided?
We offer a comprehensive warranty covering the chassis, specialized components like the pump and vacuum system, and the tank's structural integrity. Our global support network provides access to genuine spare parts (including beef tendon pipes and filter systems), detailed maintenance manuals, and technical assistance to ensure your truck operates at peak performance.
