Large Casting Part Wind Driven Generator Housing

Technical Description of Wind Driven Generator Housing

The casting-driven Generator housing is the core structural component in the industrial-driven Generator system. A precision casting process makes it and is mainly used to support the Wind Driven Generator impeller, guide the airflow direction and provide protection for the internal transmission components. Its design combines the principles of fluid mechanics and the concept of mechanical structure optimization. It plays a key role in the efficient ventilation and gas delivery systems in the fields of energy, electricity, metallurgy and chemical industry.

1. Material and Process Characteristics of Wind Driven Generator Housing

Mainstream products are mostly made of HT250 gray cast iron or QT450 ductile iron and are formed by sand casting or lost foam casting. Gray cast iron has good shock absorption and wear resistance, while ductile iron has increased the tensile strength by 30%-40% while maintaining the casting advantages. Advanced smelting technology enables the surface roughness of the casting to be controlled within Ra12.5μm, and the wall thickness tolerance can reach CT8 level precision, effectively ensuring the dimensional stability of the product.

2. Structural Design Features of Wind Driven Generator Housing

The shell adopts an volute flow channel design, and the cross-sectional area of the flow channel increases according to the law of equal annular volume, ensuring smooth airflow and reducing kinetic energy loss by more than 18%. The main structure is equipped with radial reinforcement ribs, and the thickness of the key pressure-bearing parts is increased to 1.3 times the reference wall thickness, and the static load capacity can reach 10kN/m². The air inlet and outlet flanges are strictly processed according to ISO5801 standards and equipped with sealing grooves and positioning stoppers to ensure the air tightness of the system. The built-in guide baffle and silencer cavity design reduces the working noise by 6-8dB(A) compared with the traditional welded shell.

3. Performance Advantages of Wind Driven Generator Housing

1. The overall casting structure eliminates the risk of stress concentration in the weld, and the fatigue life is increased by 3 times

2. The precision molding process ensures that the flow channel line deviation is ≤0.5mm and the aerodynamic efficiency is increased by 12%

3. The double-wall hollow structure is equipped with heat dissipation fins to achieve temperature rise control ≤35K

4. The standardized interface design is compatible with the GB/T 19075 standard impeller assembly

4. Application Adaptability of Wind Driven Generator Housing

The product specifications cover the DN200-DN2000 caliber range and are suitable for 4-72, 9-19 and other series of centrifugal Wind Driven Generators. For special working conditions, high-temperature resistant alloys (working temperature ≤650℃) or duplex stainless steel materials (corrosion resistance grade C4) can be selected. The surface can be shot, peened, or nitrided to improve the service life in harsh environments significantly.

The casting Wind Driven Generator Housing has passed the ISO9001 quality management system certification. With the intelligent machining production line, it has achieved large-scale production with an annual production capacity of 200,000 sets, showing excellent reliability in scenes such as desulfurization Wind Generators in thermal power plants and central ventilation Wind Generators in mines.
