Application of High-Pressure Pumps in Sewer Jetting Vehicles
The high-pressure pump is the core component of a sewer jetting truck, generating a high-pressure water jet to clear blockages and sediment buildup inside pipes. The following table will help you quickly grasp an overview of how high-pressure pumps are used in jetting trucks:
| Application Dimension | Key Takeaways |
|---|---|
| How it works | Using a high-pressure pump, normal-pressure water is pressurized to form a high-speed water jet, which then impacts, cuts, and removes blockages such as oil stains, sludge, and scale from the inner walls of pipelines via a specially designed nozzle. |
| Performance parameters | Work pressure typically ranges from 16 to 22 MPa (e.g., 16–19 MPa, 20 MPa, 22 MPa), and some models can deliver flow rates of up to 400 L/min. |
| Technological Advantages | Highly efficient unclogging (compared to traditional methods, efficiency can be improved by up to 80%), thoroughly clean (restoring pipe interiors to their original pristine condition), widely applicable (suitable for various pipe diameters and complex operational conditions), and safe and environmentally friendly (eliminating the need for manual entry into wells while also preventing chemical reagent contamination). |
| Key Components | It mainly includes high-pressure pumps (such as plunger pumps), high-pressure hoses, and specially designed nozzles tailored for different clogging scenarios; some models even integrate a wastewater recycling system. |
? How It Works and Technological Evolution
The high-pressure pump plays a crucial role in sewer jetting vehicles, and its technology continues to advance:
Basic Working Principle High-pressure pumps (such as plunger pumps) pressurize ordinary tap water, generating A highly concentrated, high-speed water jet These water streams are ejected through specially designed nozzles, harnessing their immense impact energy to… Impact, cavitation, abrasion, wedge splitting, crushing, and delamination It acts on blockages within the pipeline—such as oil stains and sediment—in various ways, thereby achieving the purpose of unclogging and cleaning.
Diverse real-world application scenarios
High-pressure pump suction trucks can adapt to a variety of complex operating environments:
Regular Pipe Cleaning : Cleaning city sewers, industrial wastewater pipes, and more.
Tackling Stubborn Blockages and Specialized Structures : For Persistent blockage (Such as stubborn oil stains, clumps, and deposits), the new high-pressure pulsed water jet technology delivers remarkable results. . When handling cases like " Inverted Siphon "When dealing with special pipeline structures like pipelines buried deep underground—structures that are inaccessible to conventional equipment and manual intervention—high-pressure sewer cleaning vehicles, with their ultra-high-pressure water jets (impacting at over 20 MPa), emerge as an effective solution." 。
Multi-functional tasks : Many high-pressure cleaning vehicles also Can be equipped with a water-spraying device ,兼具 Greening irrigation, mist spraying for dust suppression, and pavement washing Functions such as these can even be used in emergencies. Firefighting , achieving multi-purpose functionality in a single vehicle.
? Summary
The high-pressure pump, serving as the "heart" of the sewer jetting vehicle, utilizes high-pressure water jet technology to provide a method that Efficient, environmentally friendly, and highly adaptable The pipeline unclogging solution. With the application of new technologies such as pulsed high-pressure pumps and sewage circulation systems, the efficiency of high-pressure unclogging operations—and their ability to handle complex working conditions—will continue to improve.
We hope the information above helps you gain a more comprehensive understanding of how high-pressure pumps are used in sewer jetting vehicles. If you have further questions about specific equipment models or more detailed application scenarios, feel free to reach out anytime.
