Advantages of cleaning the suction pump of the sewage truck
The suction pump of the cleaning and suction truck has the following advantages:
1. Efficient sewage suction capacity: The cleaning and suction truck adopts a high-performance vacuum sewage pump, which has the characteristics of fast suction speed and long suction range. It can quickly suck the sediment, sludge, wastewater, etc. in the pipeline into the tank, effectively solving the problems of urban drainage pipeline blockage, sewage treatment plant sludge cleaning, etc.
2. Energy saving and environmental protection: Based on the adoption of new foreign technologies and equipment, pipeline dredging vehicle has taken the lead in developing and introducing high flow and high vacuum jet suction technology, which has increased the suction depth of the vehicle from 9 meters underground to 20 meters underground, greatly improving the applicability and operating range of the vehicle. At the same time, the sewage treated by the suction truck can meet the national discharge standards, truly achieving energy-saving, efficient, and environmentally friendly operations.
3. Multifunctionality: The cleaning and suction truck can be equipped with a water circulation pump, sprinkler system, or high-pressure cleaning pipeline dredging device according to customer needs, achieving multi-purpose use and saving customers' purchase costs. In addition, the sewage suction truck can also perform pipeline dredging operations, further expanding its application scope.
4. Easy to operate and low maintenance cost: The cleaning and suction truck is easy to operate and has low maintenance costs, making it suitable for operations in various corners of the city. Its design is reasonable, using a high-power water ring vacuum pump with strong suction capacity and the ability to operate for a long time. Even with half pipe suction, it can ensure processing speed.
The common problems and solutions for cleaning the suction pump of a sewage truck mainly include the following:
1. The suction pump does not suck or has a small suction force:
a. Anti overflow valve blockage: Check whether the anti overflow valve is blocked by dirt and clean the blockage.
b. Leakage: Check the sealing condition of all parts to ensure that there is no leakage.
c. The water temperature in the water circulation pump's water tank is too high: replace the cold water or ensure that the water tank switch is turned on.
d. Blockage in the inlet pipe of the sewage pump: Clean the inlet pipe to ensure unobstructed flow.
2. Insufficient suction of sewage pump:
a. If there is no oil or too little oil in the vacuum pump: add 1-2 liters of engine oil.
b. The system is blocked by dirt: completely disassemble and clean the suction pipeline system, and remove the blockage.
c. Excessive system leakage: Identify and repair the leakage point.
d. Softening of oil suction and return pipes: replace hard pipes or reinforce hoses.
3. Suction pump malfunction:
a. Wear or poor sealing: Check and replace worn parts or sealing rings.
b. Import pipeline blockage: Clean the import pipeline to ensure unobstructed flow.

Working principle and maintenance suggestions of suction pump:
The working principle of the sewage suction pump includes water and gas circuits, and the suction and discharge of pollutants are achieved through the cooperation of the water circulation pump and the sewage suction pump. To ensure the normal operation of the suction pump, it is recommended to regularly check the wear of each component, replace worn parts in a timely manner, and maintain good sealing at all locations to avoid air leakage. In addition, regularly clean the inlet and suction piping systems to prevent blockages and ensure the normal operation of the system.
