![]() ![]() All performance will be tested in the dredger when it starts working. The manufacturer must design and manufacture the pump as a prototype and deliver the prototype to the dredger without testing and performance checks. The size of these dredge pumps makes building a laboratory for testing and analysis extremely difficult-if not impossible. Foundries with casting capacity of 50 tons and heavy-steel machinery 6 meters in diameter are required when casting and machining the pump cases. Pumps must be tested and analyzed for efficiency and performance. New design methods are needed to efficiently adapt to the new market demand. Larger suction pipes and dredge pumps must be designed to fill the dredgers in less than two hours. Dredge pump size must increase from 1,400 to 1,600 mm-even 1,800 mm. The 3-D models take into account such performance measurements as flow rate, head and cavitation for many of the pump's components.ĭemand has recently grown in the market for even bigger dredgers. Equipment replacement can eat away at operational efficiency and increase the dredger's overall lifetime costs.įigure 3. Clogged impellers and breaking vanes also pose risks to pump performance. ![]() The soil tends to settle down and slide on the pipe bed, depending on the flow speed.Īnother challenge is that pump parts wear quickly. The pumped water does not behave like a homogenous fluid because of the different viscosities. They must carry water filled with a diverse, dense mixture of solids, including mud, fine sand, coarse sand, gravel, stones and other debris. Dredge pumps also consume the most power during operation, so efforts to reduce the pump's power needs through smarter design are critical.ĭredge pumps involve more complex engineering challenges than water pumps. The dredge pump is a dredger's main component and is critical to achieving production. At its location in the UAE, Dredge Yard engineers develops and supplies dredging and mining equipment such as dredge pumps, ball joints, cutter heads and complete dredgers. ![]()
