High-Pressure Water Piling / Hydro Jetting for Piling – Application Fields
▲Technical Principle The high-pressure water stream (typically at pressures between 150-400 Bar or even higher) generated by a pump is ejected through special nozzles installed at the pile tip or along the pile side. These high-velocity water jets serve two main purposes: 1. Lubrication and Resistance Reduction: They scour the interface between the pile and the soil, creating a slurry lubrication layer that significantly reduces skin friction. 2. Cutting and Soil Breaking: They directly impact, cut, and liquefy the soil stratum below the pile tip, reducing end-bearing resistance and allowing the pile to penetrate more easily. ▲Core Application Fields 1.Application Description: This is the most classic application. When driving open-ended pipe piles or H-piles, the water jet (often inserted inside the pile or attached to its side) simultaneously scours the soil inside and around the pile. This drastically reduces driving resistance and prevents damage or deformation of the pile head from prolonged hammering. Especially suitable for thick sand layers. 2. Application Description: Driving PHC piles into dense sand or stiff clay layers encounters enormous resistance and easily damages the pile head. Hydro jetting effectively lubricates the pile shaft, assists in penetrating hard layers, significantly improves driving efficiency, and protects the...

Heat Exchanger High-Pressure Water Automatic Cleaning Device: An Efficient and Intelligent Maintenance Solution
In the industrial sector, the maintenance of heat exchangers has always been a critical and challenging task. The advent of high-pressure water automatic cleaning systems has revolutionized this field, offering unparalleled efficiency and precision. Heat exchangers are indispensable in industries such as petroleum, chemical, thermal power, and metallurgy. However, during operation, the inner walls of their densely packed pipe networks are prone to scaling and fouling. These deposits not reduce heat transfer efficiency but also increase energy consumption and even pose safety risks like leaks or explosions . Traditional cleaning methods, such as manual scrubbing or chemical cleaning, are often inefficient, time-consuming, and potentially damaging to the equipment. Chemical cleaning also carries the risk of environmental pollution and requires careful handling of corrosive agents . The Core Advantages of High-Pressure Water Automatic Cleaning Technology High-pressure water automatic cleaning technology utilizes the impact force of high-velocity water jets to remove scale, dirt, and other deposits from heat exchanger pipes. This method eliminates the need for chemical solvents, making it an environmentally friendly solution that avoids secondary pollution .
