真空泵进出口端口

Vacuum pump inlet/outlet ports are precision-engineered connection points that control gas flow into and out of vacuum systems.

技术定义与适配语境
典型 真空泵进出口端口 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

Inlet/outlet ports on vacuum pumps are critical interface components designed to establish and maintain airtight connections between the pump and external systems. The inlet port serves as the entry point for gases being evacuated from the vacuum chamber, while the outlet port expels compressed gases to the atmosphere or to subsequent processing stages. These ports feature standardized flange configurations, sealing surfaces, and mounting provisions to ensure leak-tight operation under varying pressure differentials.

定义
Inlet/outlet ports on vacuum pumps are critical interface components designed to establish and maintain airtight connections between the pump and external systems. The inlet port serves as the entry point for gases being evacuated from the vacuum chamber, while the outlet port expels compressed gases to the atmosphere or to subsequent processing stages. These ports feature standardized flange configurations, sealing surfaces, and mounting provisions to ensure leak-tight operation under varying pressure differentials.
工作原理
Inlet ports create a pressure differential that draws gases into the pump's compression mechanism, while outlet ports release compressed gases against atmospheric or system backpressure. Both ports utilize precision-machined sealing surfaces and standardized connection interfaces to maintain vacuum integrity and prevent contamination ingress.
材料
Stainless steel (304/316)aluminum alloys (6061-T6)brass (C36000)with optional PTFE or Viton sealing elements. High-vacuum applications may use electropolished stainless steel or aluminum with copper gaskets.
Leak Rate
<10^-9 mbar·l/s
Port Size
DN16 to DN100 (ISO-KF) or 1/4" to 4" NPT
Flange Type

Surface Finish
Ra ≤ 0.8 μm for high vacuum
Pressure Rating
10^-9 to 10^3 mbar
Temperature Range

常见问题

What is the difference between ISO-KF and CF flange connections?

ISO-KF (Klein Flange) uses clamp connections with elastomer seals for medium vacuum (10^-9 to 10^3 mbar), while CF (ConFlat) uses metal gaskets and bolted flanges for ultra-high vacuum applications (below 10^-9 mbar).

How do I prevent leaks in vacuum pump ports?

Ensure proper surface finish (Ra ≤ 0.8 μm), use correct gasket materials (Viton for general vacuum, copper for high vacuum), follow specified torque values during assembly, and perform regular helium leak testing.
