高剪切转子-定子组件

基于 CNFX 目录中多个工厂资料的聚合洞察,高剪切转子-定子组件 在 化学制造 行业中通常会围绕 标准工业配置 到 重载生产要求 进行能力评估。

技术定义与核心装配

一个典型的 高剪切转子-定子组件 通常集成 Rotor 与 Stator。CNFX 上列出的制造商通常强调 Stainless Steel 316L 结构,以支持稳定的生产应用。

A precision mechanical assembly designed to generate intense shear forces through the high-speed rotation of a rotor within a closely fitted stator, creating micro-scale mixing and emulsification.

技术定义

Within the Methyl Emulsion production system, this assembly serves as the core mechanical component responsible for creating stable emulsions. It operates by rapidly rotating the rotor at high speeds within the stationary stator, generating intense shear forces that break down methyl compounds and other ingredients into microscopic droplets, ensuring uniform dispersion and stable emulsion formation critical for product consistency and quality.

工作原理

The rotor rotates at high speeds (typically 3,000-10,000 RPM) within the stationary stator. The narrow clearance between rotor and stator creates intense shear forces that break down fluid components into micron-sized droplets. This mechanical energy input creates cavitation and turbulence, facilitating rapid emulsification of methyl compounds with other formulation ingredients.

常见问题

What are the primary applications of this high-shear rotor-stator assembly in chemical manufacturing?

This assembly is designed for applications requiring intense shear forces, including emulsification of immiscible liquids, dispersion of solids into liquids, particle size reduction, and creating stable suspensions in chemical production processes.

Why is Stainless Steel 316L used in the construction of this assembly?

Stainless Steel 316L offers superior corrosion resistance against harsh chemicals, high-temperature stability, and excellent mechanical strength, making it ideal for chemical manufacturing environments where purity and durability are critical.

How does the rotor-stator design achieve micro-scale mixing and emulsification?

The high-speed rotation of the rotor within the closely fitted stator creates intense hydraulic shear and turbulence, breaking down particles and droplets to micron or sub-micron levels through mechanical energy transfer, resulting in uniform mixing and stable emulsions.
