技术定义与适配语境
典型 分配流浆箱 会按材料、尺寸公差、适配关系和失效风险在 造纸 中评估。

The Distribution Manifold is a critical hydraulic component within the headbox of a paper machine, designed to receive pulp slurry from the inlet and distribute it uniformly across the full width of the forming section. It ensures consistent fiber distribution, basis weight profile, and sheet formation quality by controlling flow velocity, pressure, and turbulence through precisely engineered internal channels and flow conditioning elements.

定义
The Distribution Manifold is a critical hydraulic component within the headbox of a paper machine, designed to receive pulp slurry from the inlet and distribute it uniformly across the full width of the forming section. It ensures consistent fiber distribution, basis weight profile, and sheet formation quality by controlling flow velocity, pressure, and turbulence through precisely engineered internal channels and flow conditioning elements.
工作原理
Operates on hydraulic flow distribution principles using internal baffles, channels, and flow straighteners to convert turbulent inlet flow into a uniform, controlled laminar flow across the machine width. Pressure differentials and flow resistance are carefully balanced to achieve even distribution regardless of position across the manifold.

Stainless steel (typically 316L or 304)duplex stainless steels for corrosive applicationswith polished internal surfaces (Ra < 0.8 μm) to prevent fiber hang-up and contamination.
Flow Rate
50-2000 L/min per meter width
Width Range
2-12 meters
Surface Finish
Electropolished to Ra 0.4-0.8 μm
Connection Type
Flanged or welded
Temperature Range
10-90°C
Operating Pressure
0.5-3.0 bar
标准
ISO 9001DIN 11850ASME BPE
