INDUSTRY COMPONENT

Vacuum System Connection

Vacuum system connection for multi-stage evaporators ensuring leak-tight seals and efficient vapor transfer between stages.

Component Specifications

Definition
A specialized industrial component designed to create and maintain vacuum-tight connections between successive stages of a multi-stage vacuum evaporator train. It facilitates the transfer of vapor from one evaporation chamber to the next under controlled vacuum conditions, ensuring minimal pressure drop and preventing air ingress that would compromise evaporation efficiency. These connections typically incorporate flanges, gaskets, and sealing mechanisms rated for high vacuum applications.
Working Principle
Operates by creating a sealed pathway between evaporator stages using vacuum-rated flanges and gaskets. The connection maintains the pressure differential established by the vacuum pump system, allowing vapor to flow from higher-pressure stages to lower-pressure stages while preventing atmospheric air from entering the system. Proper alignment and clamping force ensure uniform gasket compression for consistent sealing performance across thermal cycles and mechanical vibrations.
Materials
Stainless steel (AISI 316L or 304L) for corrosion resistance, with vacuum-rated elastomer gaskets (Viton, EPDM) or metal gaskets (copper, aluminum) for high-temperature applications. Flange surfaces often have machined grooves for O-rings or spiral-wound gaskets.
Technical Parameters
  • Leak Rate <10^-9 mbar·L/s
  • Size Range DN25 to DN500
  • Surface Finish Ra ≤ 0.8 μm for metal seals
  • Connection Type Flanged (ISO-KF, CF, ASA)
  • Pressure Rating High vacuum (<10^-3 mbar)
  • Temperature Range -20°C to 200°C
Standards
ISO 2861, DIN 28403, ASME B16.5

Frequently Asked Questions

What is the most critical factor in vacuum system connection performance?

Leak integrity is paramount. Even minor leaks can significantly reduce vacuum levels, increasing energy consumption and compromising evaporation rates. Proper gasket selection, surface preparation, and torque application during installation are essential.

How often should vacuum connections be inspected?

During routine maintenance cycles (typically every 6-12 months), or whenever system performance degrades. Inspect for gasket compression set, flange surface damage, and signs of corrosion. Helium leak testing is recommended for critical applications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
