Product Specifications

Technical details and manufacturing context for Suction Box

Definition
The suction box is a critical component within industrial systems that utilizes vacuum pressure to efficiently collect, contain, and transport particulate materials, powders, or granular substances from various process points to designated collection or processing areas, ensuring material flow continuity and preventing contamination or loss.
Working Principle
The suction box operates by connecting to a vacuum source that creates negative pressure within its enclosed chamber. When material enters through the inlet, the pressure differential draws it into the box where it accumulates or passes through to connected transport lines. Internal baffles or filters may separate materials from the air stream, while discharge mechanisms allow controlled material release when vacuum is released or through mechanical means.
Common Materials
Stainless Steel, Polypropylene
Technical Parameters
  • Air flow capacity at specified vacuum level (m³/h) Standard Spec
Components / BOM
  • Inlet Port
    Entry point for materials being suctioned into the box
    Material: Stainless Steel
  • Vacuum Connection
    Interface for connecting to vacuum source or system
    Material: Stainless Steel
  • Discharge Valve
    Controls material release from the suction box
    Material: Stainless Steel with elastomer seals
  • Pressure Relief Valve Optional
    Safety device to prevent over-pressurization
    Material: Stainless Steel
Engineering Reasoning
0.8-1.2 bar vacuum (80-120 kPa absolute pressure)
0.65 bar vacuum (65 kPa absolute pressure) at 20°C ambient
Design Rationale: Cavitation-induced impeller erosion due to vapor bubble collapse at NPSHa < 3.0 m
Risk Mitigation (FMEA)
Trigger Filter clogging exceeding 150 Pa pressure drop
Mode: Motor overload trip at 110% rated current for 30 seconds
Strategy: Differential pressure sensor with automatic bypass at 120 Pa
Trigger Seal degradation from abrasive particles > 50 μm concentration
Mode: Vacuum loss below 0.9 bar at maximum flow rate
Strategy: Cyclone separator with 99% efficiency at 25 μm cut-point

Frequently Asked Questions

What materials are available for the suction box in paper manufacturing?

Our suction boxes are available in stainless steel for high durability and corrosion resistance, or polypropylene for chemical resistance and lighter weight applications in paper manufacturing processes.

How does the suction box create negative pressure for material transport?

The suction box connects to a vacuum system through the vacuum connection port, creating controlled negative pressure that efficiently collects and transports paper materials, fibers, or waste through the industrial system.

What safety features are included in the suction box design?

Each suction box includes a pressure relief valve to prevent over-pressurization, along with a discharge valve for controlled material release and an inlet port designed for optimal flow and system integration.

Can I contact factories directly on CNFX?
