From thermal power to nuclear and hydro-power generation, the efficiency of fluid machinery is important. At the heart of these systems lie the pumps—specifically, multistage centrifugal pumps designed for high flow and high head applications. The performance of these pumps is not just determined by the motor, but critically by the hydraulic components inside, with the casting guide vane body playing a decisive role in energy conversion.
The function of the casting guide vane body in high-head Applications:
In high-pressure boiler feed pumps or condensate pumps used in power generation, the fluid exits the impeller at high velocity. The casting guide vane body is the stationary component responsible for capturing this high-velocity fluid and efficiently converting its kinetic energy into potential energy (pressure) while directing it to the next stage.
For pumps requiring high head, the internal geometry of the casting guide vane body must be flawless. Surface roughness or dimensional inaccuracies can lead to turbulence, cavitation, and significant hydraulic losses. This is why standard casting methods often fail to meet the rigorous demands of the modern energy industry.
Why "Steel Only" Matters in Power Generation?
Unlike low-pressure agricultural or municipal pumps that might use cast iron, power plant pumps operate under extreme conditions. High temperatures in thermal power plants and radiation concerns in nuclear facilities demand superior materials.
Dalian Jiachuang Metal Manufacturing Co., Ltd. focus exclusively on steel. We do not process grey iron or ductile iron.
Our expertise lies in:
Carbon Steel: For standard high-pressure piping and pump casings.
Martensitic & Austenitic Stainless Steel: Essential for corrosion resistance in cooling loops.
High-Temperature Alloys: Such as Inconel and Hastelloy, which are capable of withstanding the extreme thermal stress found in steam turbines and nuclear reactors.
Our Manufacturing Edge: Alkaline Phenolic Resin Sand.
To achieve the intricate internal channels required for a high-efficiency casting guide vane body, Dalian Jiachuang utilizes advanced Alkaline Phenolic Resin Sand technology.
Located in Dalian, Liaoning Province, our 30,000-square-meter facility houses a production line equipped with a 15t/h mobile sand mixer and a 12t/h fixed sand mixer. This technology offers distinct advantages for energy sector castings:
High Dimensional Accuracy: Crucial for the complex curvature of guide vanes.
Excellent Surface Finish: Reduces friction losses inside the pump, directly contributing to the "high flow" capability.
Hot Tearing Resistance: vital when casting high-grade steel alloys that are prone to thermal defects.
Capacity and Quality Assurance:
With nearly 300 employees, including 2 senior engineers and over 30 technical professionals, we bridge the gap between design and durability. Our melting capacity, featuring multiple 0.5T, 1T, 3T, and 5T intermediate frequency induction furnaces, allows us to handle both prototype development and mass production for large-scale energy projects. whether it is for a coal-fired plant or an LNG receiving terminal, our casting guide vane bodies are tested to ASME, ASTM, and ISO standards to ensure zero failure rates.
