An overview of the suction truck and its principle
Suction truck is a new type of sanitation garbage truck, which can collect, remove and eliminate sludge and sewage, and prevent secondary pollution. Suction truck can be self suction and self drainage pipeline. It has the advantages of faster working speed, large volume and convenient transportation. Transportation of excreta, slurry, petroleum and other liquid chemicals in the current technology, the sewage treatment vehicle uses the mechanical pumping time pump shell of the sewage treatment vehicle, especially suitable for the suction of sludge, sludge, sand and gravel in the sewer, transportation and discharge of large bricks and objects. In the whole process of suction, the suction plastic hose is immersed in the liquid surface from beginning to end. After the gas in the sludge tank is sucked in, it becomes thinner and thinner because it cannot be filled, so the working pressure in the tank is less than the atmospheric pressure. The sludge is under the working pressure in the air, and it enters the sludge tank according to the sludge. Hygroscopic tube. Or because the siphon is close to the bottom of the storage tank, and the gas is continuously discharged into the sludge tank, because there is no development direction, the gas is reduced, resulting in the working pressure in the storage tank is higher than the atmospheric pressure. Under the effect of air compression, the sludge is discharged according to the siphon and breathing pipe outside the tank.
Joint dredger
However, at present, the key technology of sewage treatment vehicle is to use atmospheric pressure to pump sludge. The aspect ratio of sludge has some shortcomings. The scope of pumping is about 8 meters, and it is difficult to achieve more than 10 meters. When dealing with higher vertical depth requirements, the current sewage pumping trucks seem to have significantly reduced pumping capacity. For example, under the condition that the vertical depth of sludge must be 25 meters, the environmental pollution absorption capacity of the current sewage pumping truck enterprises is greatly reduced.
Therefore, in order to better deal with the technical problems, an integral sewage suction truck with high adsorption capacity, high efficiency and thorough sludge cleaning is proposed.


The suction truck adopts the mechanical pump of China's leading technical suction truck, which has large adsorption capacity and long suction range. It is especially suitable for the suction, transportation and discharge of sediment in the sewer pipe, especially for the suction of slurry, sludge, gravel, bricks and other large objects in the sewer pipe.
The special type of combined dredger is composed of retarder, rotating shaft, vacuum pump, working pressure tank hydraulic press, pipeline network system software, vacuum meter, fecal window, hand washing and disinfection equipment, etc. the following vehicle is equipped with high-power vacuum pump and high-quality hydraulic transmission system. The tank can be formed by aluminum die casting at one time, and the tank can be put back Double track dump truck. The waste in the tank can be dumped immediately according to the rear cover plate. It has the characteristics of high vacuum value (higher adsorption capacity than the manure suction truck), large loading capacity, high efficiency and more common main uses.
The suction truck and the suction truck have the same basic principle, but the suction truck and the suction truck have different main uses. The difference depends on the fact that the tank body of the sewage truck is an annular tank, which has a closer structure, can withstand higher working pressure and higher adsorption capacity, and can be used to collect and transport sewage and sludge.
