Industry Applications

These castings are used in wastewater treatment, pneumatic conveying, chemical processing, and other industries, making them versatile for international markets.

WALKSON's Roots Blower Housing Castings are high-quality components precision-engineered for industrial applications, ensuring durability, high efficiency, and extended service life in Roots Blower systems. These castings are essential for air and gas handling across diverse industries, providing the structural framework that encloses the rotors and maintains the blower's integrity under high-pressure conditions.

Function

The primary function of the Roots Blower Housing Casting is to house the rotors and ensure the blower's structural integrity. It must withstand harsh environments, high pressures, and corrosive substances, making it essential for the blower's reliable operation. The casting ensures smooth airflow, minimizes friction, and prevents inefficiencies, contributing to the blower's overall performance and longevity.

Materials

WALKSON offers Roots Blower Housing Castings in a range of materials to suit different application needs, all compliant with international standards:

· Gray Iron: Compliant with ASTM A48 and EN 1561, offering excellent machinability, cost-effectiveness, and vibration damping properties. ASTM A48 Class 30, for example, is commonly used, with a minimum tensile strength of 30,000 psi, suitable for general engineering applications (ASTM A48).

· Ductile Iron: Compliant with ASTM A536 and EN 1563, providing higher strength, ductility, and resistance to wear and tear for more demanding applications. Grades like ASTM A536 65-45-12 offer a balance of strength and toughness, ideal for high-pressure environments (ASTM A536).

· Special Alloys: Available for applications requiring high strength, corrosion resistance, or other specialized properties, such as stainless steel for corrosive environments.

The choice of material depends on the application's requirements, with gray iron being cost-effective for less demanding conditions and ductile iron preferred for higher strength and durability.

Manufacturing Process

WALKSON employs a modern and standardized manufacturing process to produce high-quality castings:

· Casting: Utilizing state-of-the-art casting techniques, including sand casting or investment casting, to produce precise and defect-free components. Sand casting is commonly used for its cost-effectiveness, while investment casting ensures high precision for complex geometries.

· Finish Machining: Advanced CNC technology is used for meticulous finish machining, ensuring smooth surfaces, perfect tolerances, and seamless integration into blower systems. This step is crucial for achieving the required dimensional accuracy and surface finish.

· Quality Control: Rigorous inspection and testing at every stage to ensure compliance with international standards and customer specifications, including dimensional checks and material analysis.

The process is designed to minimize defects and ensure consistency, with each casting undergoing multiple quality checks to meet industry standards.

International Standards

All manufacturing processes adhere to the following international standards:

· ASTM A48 for gray iron castings, covering general engineering use where tensile strength is a major consideration (ASTM A48).

· ASTM A536 for ductile iron castings, specifying properties for spheroidal graphite iron (ASTM A536).

· EN 1561 for gray iron castings, detailing requirements for grey cast iron with lamellar graphite (EN 1561).

· EN 1563 for ductile iron castings, specifying properties for spheroidal graphite cast irons (EN 1563).

These standards ensure that the castings meet the highest quality and performance criteria, making them suitable for a wide range of industrial applications.

Testing Procedures

To guarantee the highest quality, WALKSON conducts comprehensive testing procedures, including:

· Tensile Testing: To verify the material's strength, ensuring it can withstand operational stresses. Conducted using universal testing machines, as required by ASTM A48 and ASTM A536.

· Hardness Testing: To ensure compliance with specified hardness levels, using Rockwell or Brinell hardness testers, as per EN 1561 and EN 1563.

· Dimensional Inspection: Using Coordinate Measuring Machines (CMM) to check for accuracy in dimensions, ensuring perfect fit and function within blower systems.

· Pressure Testing: To simulate operational conditions and ensure the casting can withstand required pressures, using hydraulic or pneumatic test rigs.

· Non-Destructive Testing (NDT): Such as ultrasonic testing to detect internal defects without damaging the casting, conducted with ultrasonic flaw detectors, as per ASTM E114 and EN 12668.

Specific testing protocols are implemented as required by applicable standards, ensuring the castings meet or exceed industry expectations. Clients are welcome to witness these tests, and third-party inspectors designated by the client are accommodated to ensure transparency and trust.
