As the pace of China's modern urban construction accelerates and the scale of cities continues to expand, the corresponding demand for infrastructure construction also grows. The water consumption in cities is increasing, and so is the drainage volume. Consequently, there is a growing workload in the management, maintenance, repair, and dredging of sewage pipes. Among these tasks, sewage pipe dredging is particularly crucial and has become a task that cannot be ignored by relevant departments. Due to frequent issues such as residents indiscriminately pouring sewage and other debris into sewage pipes, as well as cement mortar from construction sites, these debris often precipitate and accumulate. Excessive accumulation can lead to pipe blockages. If not cleaned and dredged in a timely manner, sewage overflow can occur, polluting the environment, causing economic losses, and posing inconveniences to residents' lives.
The working principle involves using a high-pressure pump to convert the mechanical energy of the power source into pressure energy. Water with high-intensity pressure passes through the small holes of a high-pressure nozzle, where the pressure energy is converted into kinetic energy, forming a high-speed micro-fine water jet. This jet uses its powerful impact force to clean the object being washed, stripping and removing dirt, thus achieving the purpose of cleaning.
During actual work, water is pressurized and fed into the pipeline cleaning nozzle. Relying on the reactive force generated by the high-pressure water jet, the pipeline cleaning nozzle and high-pressure hose move in opposite directions together, simultaneously cleaning the pipe wall. The water stream sprayed out by the nozzle flushes the residual sediment on the inner wall of the pipeline to the downstream inspection well, where it is then suctioned away by a suction truck. This cleaning method is suitable for sewage pipes of various diameters. Pure water, after passing through a purification device, can also be recycled, significantly reducing cleaning costs.
The sewage pipeline dredging equipment boasts several advantages, including ease of operation, high work efficiency, environmental friendliness and non-pollution, wide application range, and energy conservation. Its cleaning length can reach up to 150 meters, and it can navigate through two right-angle bends for a cleaner cleaning. The pipe retractor utilizes a hydraulic automatic retractor, making operation more convenient. The use of a low-speed motor and an Italian crankshaft piston pump ensures its ability to work continuously for extended periods. The visual pressure and adjustment system facilitates its application in various pressure segments, and it is equipped with a high-density water inlet filtration system.
