Product Specifications

Technical details and manufacturing context for Centrifugal Wheel Assembly

Definition

The centrifugal wheel assembly is a critical component within a Marine Hull Plate Shot Blasting Machine. It is responsible for accelerating abrasive shot or grit via centrifugal force and directing it onto steel hull plates to remove rust, mill scale, and old coatings, preparing the surface for subsequent painting or treatment. This assembly is designed for continuous operation in demanding environments, with materials such as high-chromium cast iron and alloy steel used for wear-resistant parts. Key parameters include a wheel diameter of 250–500 mm, blade width of 40–120 mm, maximum speed of 1800–3600 rpm, abrasive flow rate of 100–500 kg/min, motor power of 5.5–30 kW, operating voltage of 380–690 V AC (IEC 60038), frequency of 50–60 Hz (IEC 60038), maximum operating temperature of 80–120 °C, noise level of 85–105 dB(A) at 1 m (ISO 3744), weight of 50–200 kg, blade hardness of 58–62 HRC (ASTM E18), and balancing grade of G6.3–G2.5 (ISO 21940-11). These values are reference ranges and must be confirmed for the specific model and application. The assembly operates by rotating at high speed; abrasive media fed into the center is captured by blades and ejected outward at high velocity. Proper selection requires consideration of workpiece material, desired surface finish, and production rate. Interfaces include motor mounting, abrasive feed inlet, and discharge opening. Verification questions should address actual operating conditions, such as abrasive type and size, and confirm that the assembly meets required standards. Maintenance signals include increased vibration, noise, or reduced blasting efficiency, indicating blade wear or imbalance. Failure boundaries include exceeding maximum speed or temperature, which can cause bearing failure or structural damage. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The assembly rotates at high speed. Abrasive media fed into the center of the rotating wheel is captured by blades or vanes. Centrifugal force accelerates the media outward along the blades and ejects it at high velocity through an opening or nozzle towards the target workpiece. The kinetic energy of the abrasive particles impacts the surface, removing contaminants and preparing it for coating.

Frequently Asked Questions

What is the typical wheel diameter range for this assembly?

The wheel diameter is typically in the range of 250–500 mm, but the exact value depends on the specific model and application. Always confirm with the manufacturer or supplier.

What materials are used for the wear parts?

The materials on file include high-chromium cast iron and alloy steel. These are chosen for wear resistance, but the exact grade and treatment should be verified with the supplier.

What standards are relevant for balancing and noise?

Balancing grade is specified per ISO 21940-11 (G6.3–G2.5), and noise level is measured per ISO 3744 (85–105 dB(A) at 1 m). These are reference standards; actual compliance must be confirmed.

How should I verify that the assembly meets my requirements?

You should confirm the actual parameters (e.g., speed, flow rate, motor power) with the legal manufacturer or supplier, and ensure they match your operational needs and any applicable standards.
