Vacuum Pump Graphite Rotor Vane, Oil Pump Rotor
The graphite rotor rotating nozzle is made from high purity graphite, graphite rotor specifications for Φ 70 mm to 250 mm, specifications for impeller Φ 85 mm to 350 mm, high purity oxidation resistance of graphite rotor with high strength, high temperature resistant, corrosion resistant aluminum flow characteristics.
The shape of the impeller is streamlined, which can reduce the resistance during rotation, and the friction and scouring force between the impeller and aluminum alloy liquid is relatively small.Thus, the degassing rate is above 50%, the smelting time is shortened and the production cost is reduced.Widely used in aluminum alloy foundries and aluminum products factories.
1.Introduction
Our Metal or Resin Impregnated Graphite Parts are widely used in equipments of modern industry, such as seal rings for centrifugal pumps reacting kettle for chemical engineering, hydraulic generators and rotate baking furnaces; piston rings and bushings for compressors oxygen machines and bellows, bearings for screen motors and other types of instruments; slides for motors, subways and mine brushes of electrical machinery and slides for trolleybuses, etc.
2. Specialties graphite (graphite mold, graphite crucible, graphite block, graphite rod…
Specialty carbon graphite materials include medium grain graphite, fine grain graphite, and ultra-fine grain graphite.
Specialty carbon products (Carbon specialties) will realize the carbon's extensive potential. They are high-performance products that underline the development of key industries such as electronics, machinery, and metallurgy. They are also used in cutting-edge fields of science such as semiconductors aviation and the aerospace industry.
Feature
1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, so as to ensure the reliability of product quality.
2. Corrosion resistance: Even and fine basic design will delay the erosion of crucible.
3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out.
4. Acid resistance: The adding of special materials will greatly improve the quality of crucible, especially its index of acid resistance., and will prolong the service life of graphite crucible.
5. High heat Conduction: High content of fixed carbon ensures the good heat conduction, shorten the time of dissolution, and remarkably reduce the energy consumption.
6. Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metals when dissolving.
7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality
Application
In the aluminum and zinc casting industries, nitrogen, argon or carbon tetrachloride are injected and sprayed into molten metal through graphite rotors for dehydrogenation. It can eliminate the bubbles inside the castings and improve their inner quality. Injects inert gases into the Metallic solution .
