Vacuum Manifold for Vacuum Table Systems

Product Specifications

Technical details and manufacturing context for Vacuum Manifold

Definition

The vacuum manifold is a critical component within a vacuum table system that serves as a central distribution hub. It connects the main vacuum pump or source to multiple individual vacuum ports or zones on the table surface, allowing for efficient and controlled vacuum distribution across the entire work area. This enables secure holding of materials during machining, cutting, or assembly processes. The manifold is typically manufactured from aluminum alloy, stainless steel, or engineering plastics, with the aluminum version often featuring a 6061-T6 grade and hard anodizing for wear resistance. It is designed to operate within a vacuum range of -0.1 to 0 MPa (relative to atmospheric pressure) and a temperature range of -20 to 80 °C. The number of ports can vary from 4 to 12, with port sizes ranging from G1/8 to G1/2 BSPP, and the main inlet size from G1/2 to G1 BSPP, conforming to ISO 228-1. The maximum allowable leak rate is ≤1×10⁻⁵ Pa·m³/s as per ISO 27895. Dimensions typically range from 100–300 mm in length, 50–150 mm in width, and 30–80 mm in height, with a weight of 0.5–2.5 kg depending on port count and size. The manifold may incorporate valves or dampers to control vacuum flow to specific zones, enabling selective material holding and optimized energy usage. For proper selection, engineers must verify the required number of ports, port sizes, main inlet size, and operating pressure to match the specific vacuum table design. It is essential to confirm model-specific values and standards with the legal manufacturer or supplier before procurement, as the listed parameters are reference ranges and not guaranteed for every configuration.

Working Principle

The vacuum manifold operates by creating a sealed distribution network. When the vacuum pump generates negative pressure, the manifold distributes this vacuum evenly through its internal channels to multiple outlet ports. Valves or dampers may be integrated to control vacuum flow to specific zones, allowing for selective material holding and optimized energy usage. The manifold's internal design ensures minimal pressure drop and uniform distribution across all ports, subject to the specified leak rate. Proper sealing and material integrity are critical to maintain the required vacuum level and prevent leakage.

Frequently Asked Questions

What is the typical number of ports on a vacuum manifold?

The number of ports typically ranges from 4 to 12, depending on the model and application. The exact count should be confirmed with the manufacturer for your specific vacuum table design.

What materials are commonly used for vacuum manifolds?

Common materials include aluminum alloy (often 6061-T6), stainless steel, and engineering plastics. The aluminum version may have a hard anodized surface treatment for wear resistance.

What is the operating pressure range for this manifold?

The operating pressure range is -0.1 to 0 MPa, where 0 MPa is atmospheric pressure. This indicates a vacuum range from -0.1 MPa to atmospheric pressure.

How do I verify the leak rate and standards compliance?

The maximum allowable leak rate is ≤1×10⁻⁵ Pa·m³/s as per ISO 27895. For verification, you should request test reports or certificates from the manufacturer and confirm that the specific model meets these requirements.
