with many years of marine engineering experience, Hengli can provide stable and reliable solutions for all kinds of dredging equipment, better products, help dredging equipment to improve efficiency, safety and reliability.

In the customer20 square bucket type dredging equipment project in the middle, Hengli Hydraulics has overcome difficulties such as no reference cases and water-facing operations, providing customers with a one-stop solution, including 16 sets of V30D520 main pump, a full set of hydraulic cylinders and control valve group. This set of "combined punches" concentrates all the power on the bucket to achieve a maximum depth of 22 meters.

Power Heart V30D520 heavy duty pump

in the power core configuration of this project, 16 groups of main pump units are selected. Hengli Germany InLine V30D 520 high performance large displacement piston pump. The plunger pump is famous for its advanced manufacturing technology and excellent performance. It has the characteristics of high pressure, heavy load, flexibility, intelligence, energy saving and environmental protection, which ensures the stable and reliable operation of the main pump unit, provides continuous strong power for dredging equipment, and ensures its continuous and efficient operation in high-intensity operation.

V30D520 pump pressure rating is400bar the instantaneous maximum pressure can reach450bar. At the same time, the V30D520 pump adopts the through-shaft drive form, compact structure, and can achieve a breakthrough in higher power density ratio.

Wisdom Center hydraulic control valve group

the large bucket of dredging equipment also has a higher standard for precision control under high flow and high pressure. Hengli Hydraulic is the 20-square project. Provides 3 sets of large hydraulic control valve groups with high precision and high response control performance, they ensure the stability and accuracy of bucket operation and smooth and coordinated movement.

Of these, 204WRKE Series Pilot Operated Proportional Reversing Valve as the main force, it shows the advantages of large flow capacity, high working pressure, good static performance, fast dynamic response and reliable action.

Efficient execution full set of customized hydraulic cylinder

hydraulic cylinder is the main executive component to ensure the bucket digging action is strong, accurate and stable. Hengli Hydraulic can provide customers with a complete set of products such as boom, stick, bucket hydraulic cylinder, etc. Hengli's special high corrosion-resistant composite plating process can also ensure that the hydraulic cylinder has a longer service life in the freshwater splash zone.

With its deep technical accumulation and fearless innovative spirit, Hengli Hydraulics opens the way in the no-way and makes the tide in the deep water area. In the future, Hengli Hydraulic will continue to cultivate fluid power and control technology, and contribute more reliable, efficient and intelligent "China Hydraulic Power" to global engineering projects"
