Durable High-Efficiency Graphite Rotor for Aluminum Degassing Graphite Rod Graphite Shaft High Temperature Graphite Rotor Product

Product Description

Product Description
Graphite rotor is a commonly used critical component in vacuum pumps, especially in environments with high vacuum or corrosive gases. It is typically employed in rotary vacuum pumps, such as molecular pumps and turbo molecular pumps.
Material: Graphite rotors are made from graphite, a material known for its excellent high-temperature resistance, chemical stability, and mechanical strength. This enables graphite rotors to operate in various harsh vacuum environments.
Structure: Graphite rotors usually feature a design with rotational symmetry, allowing for the uniform extraction of gases during operation. They may consist of a series of spiral or helical shapes, contributing to the efficiency of the vacuum pump.
Product Features
High Temperature Resistance: Graphite rotors exhibit excellent resistance to high temperatures, enabling them to operate effectively in high-temperature environments without failure. This makes them particularly well-suited for applications that involve handling high-temperature gases or operating under elevated temperature conditions.
Corrosion Resistance: High-purity graphite typically demonstrates outstanding resistance to corrosion, providing an advantage in handling corrosive gases or chemicals.
Lightweight: Graphite is a relatively lightweight material, aiding in reducing rotor inertia, making it easier to achieve high-speed rotation, and enhancing pump efficiency.
Self-Lubrication: Graphite possesses self-lubricating properties, reducing friction, extending the lifespan of graphite rotors, and decreasing maintenance requirements.
Thermal Conductivity: Graphite exhibits excellent thermal conductivity, aiding in the uniform dispersion of heat in high-temperature environments and preventing overheating.
Stability: Graphite rotors typically exhibit stable mechanical performance during operation, maintaining stable operational status over extended periods.
Manufacturability: Graphite is relatively easy to machine, allowing for the manufacturing of various complex shapes to accommodate different pump designs and requirements.
Wide Applications: Due to its superior properties, graphite rotors find extensive applications in areas such as vacuum pumps, gas separation, and the chemical industry, among others.
Product Usage Ensure the graphite rotor is clean and free from contaminants before use. Carefully install the graphite rotor, ensuring proper insertion and alignment. Confirm correct installation of the graphite rotor before starting the rotating equipment. Physical And Chemical Index
