High pressure water dredging machine is an efficient and environmentally friendly pipeline dredging equipment, widely used in various fields such as life, commerce, industry, and municipal engineering. It uses high-pressure water jet technology to remove blockages in pipelines and has a wide range of applications. The high-pressure dredging machine uses high-pressure water jet technology to dredge and clean pipelines. It pressurizes water to several hundred kilograms through a high-pressure water pump, and then sprays it out at high speed through a dredging nozzle, using the impact force of the water flow to remove dirt, silt, and other obstacles inside the pipeline.
