Component Specifications

Definition
A suction port is a precisely engineered inlet component in ejector nozzle systems designed to generate negative pressure through the Venturi effect. It serves as the primary entry point where materials are drawn into pneumatic conveying streams, featuring optimized geometry to minimize pressure drop while maximizing flow efficiency. The component typically includes mounting interfaces, sealing surfaces, and flow conditioning elements to ensure reliable operation in industrial material handling applications.
Working Principle
The suction port operates on the Venturi principle where high-velocity compressed air passing through a constricted section creates a low-pressure zone at the inlet. This pressure differential generates suction force that draws materials into the conveying stream. The port's geometry is designed to maintain laminar flow conditions and prevent material accumulation or clogging during operation.
Materials
Typically manufactured from stainless steel (AISI 304/316), aluminum alloys (6061-T6), or engineered polymers (PTFE, PEEK) depending on application requirements. Materials must exhibit corrosion resistance, wear resistance, and compatibility with conveyed materials.
Technical Parameters
  • Port Diameter 10-100 mm
  • Surface Finish Ra ≤ 1.6 μm
  • Connection Type Flanged, threaded, or quick-connect
  • Pressure Rating Up to 10 bar
  • Vacuum Capacity Up to 0.8 bar negative pressure
  • Temperature Range -20°C to 150°C
Standards
ISO 1219, DIN 24300, ISO 5599
