Product Description Main products include: graphite rings for dynamic sealing, static sealing rings, graphite bearings, lubricating columns, graphite vanes, and mechanical sealing parts impregnated with various metals or resins.Characteristics of graphite for mechanical application: High mechanical strength, corrosion resistance, good wear resistance and self-lubrication. Advantages of Graphite for Mechanical Industry:Corrosion resistance: Graphite materials have good resistance to a variety of corrosive media and can work in a corrosive environment for a long time without being damaged, greatly extending the service life of the seals.Self-lubrication: Graphite materials have unique self-lubricating properties. In the absence of lubricant or when the lubricant is insufficient, self-lubrication can be achieved through the friction of its surface microstructure. This characteristic enables graphite seals to reduce friction resistance, minimize wear, and improve sealing efficiency during operation.Thermal conductivity: Graphite has a high thermal conductivity coefficient, second only to silver, copper, and aluminum, and is the only non-metallic material with a high thermal conductivity rate. Therefore, it can dissipate the generated frictional heat in a timely manner, thereby reducing the temperature of the sealing end face, which is very necessary for improving its reliability and service life. 4. Low linear expansion coefficient: The linear expansion coefficient of graphite is low, approximately 1/2 to 1/4 of that of metals. When the temperature rises, its thermal deformation is small, which is beneficial for maintaining the parallelism of the sealing end face. At the same time, it has good thermal stability, excellent heat resistance, cold resistance, and thermal shock resistance. 5. Compression resilience: After being processed and formed, graphite seals have a certain degree of compression resilience. When subjected to pressure, the seals can undergo elastic deformation to fill the sealing gap and achieve a tight seal. When the pressure is removed, the seals can quickly return to their original shape, maintaining the stability of the sealing performance.6. The applications of mechanical graphite sealing materials are very extensive, mainly used in various mechanical equipment that requires sealing, such as pumps, valves, reaction kettles, and high-temperature equipment such as high-temperature furnaces and kilns. In these devices, graphite sealing materials, with their excellent performance, can effectively prevent medium leakage and ensure the normal operation of the equipment. At the same time, graphite sealing materials are also widely used in the chemical industry. In the face of various corrosive media, graphite sealing materials can provide reliable sealing effects.Graphite sealing ringGraphite sealing ring is a component used for mechanical seals. Its high strength, low friction, high temperature and high pressure resistance and self-lubrication make it an ideal choice for dynamic and static sealing ring materials. It is made from high purity graphite or impregnated resin/metal graphite to achieve superior performance.Graphite sealing rings are divided into static and dynamic sealing rings, with static sealing rings installed on fixed components and dynamic sealing rings installed on rotating shafts. These sealing rings are usually used in applications such as pumps, compressors, and turbines to form a sealing interface that prevents liquid or gas leakage. Therefore, it puts high requirements on the performance of sealing rings, including strength, hardness, porosity, lubrication, and heat resistance.FeaturesSelf-lubrication, low friction.High tensile strength and good thermal shock resistance.High conductivity, low coefficient of thermal expansion.Good chemical & corrosion resistance.Excellent high temperature stability.Graphite Bearing Graphite bearing is a commonly used lubricant part in the industrial machinery and is divided into radial bearing and thrust bearing. Bearing materials include metal, nonmetal and composite materials. Graphite bearing is a sliding bearing with high mechanical equipment performance requirements.Unlike metal bearings, graphite bearing has self-lubrication, qualitative light, high temperature resistance, corrosion resistance and other superior properties. It can not only be used in high temperature, low temperature, high speed and low speed sliding conditions, but also can be used in strongly corrosive gas and liquid media conditions. It is widely used in centrifugal pumps, submersible pumps, liquid pumps, and other mechanical equipment.FeaturesExcellent self-lubrication.High thermal conductivity and thermal stability.Good chemical corrosion resistance.Good wear resistance and high mechanical strength.Graphite Rotors and Vanes - An Essential Part of Vacuum PumpThe working principle of vacuum pump is to compress gas and discharge it by rotating the graphite rotors and vanes. Specifically, as the graphite rotor rotates, the space between the vacuum pump graphite vanes and the pump body continuously changes, thus sucking, compressing, and discharging gas. The main function of the graphite blades is to capture the gas and move it from the low pressure area to the high pressure area when they rotate inside the vacuum pump. The quality, shape, and material of the graphite vanes have an influence on the performance and service life of the vacuum pump.Vacuum pump graphite rotors and vanes have good self-lubrication and wear resistance and can work normally in dry-running state without additional lubricating oil or grease. Therefore, they can effectively avoid the contamination and damage to the vacuum pump caused by lubricating oil or grease. Meanwhile, they have good corrosion resistance and high temperature resistance, and can adapt to harsh working environments, so they are widely used in dry vacuum pumps.FeaturesLow friction, low coefficient of thermal expansion.Excellent self-lubrication.High thermal conductivity and thermal stability.Good chemical corrosion resistance.Wear resistance and high mechanical strength.Technical Data of Graphite for Mecanical ApplicaitonsGradeImpregnated MaterialBulk Densityg/cm3Shore HardnessHsFlexural StrengthMpa≥Compressive StrengthMpa≥Porosity%Coefficient of Thermal Expansion×10/oCAir PressureKGWater PressureMpaMaximum TemperatureoCM126PCopper 2.4 - 2.675802503.066 - 72.4500M116DAntimony 2.2 - 2.575702402.05.56 - 72.4400M252AAluminum 2.140851802.07.56 - 72.4400M254BBabbitt Metal 2.4606416095.56 - 72.4200M116KResin (Phenolic, Furan, Epoxy)1.82 - 2.092752450.85.56 - 72.4200Strict Quality Control Ensures High Quality Products Safe Packing Question and Answer:Q:Are you a manufacturer or trading company?A:We are a manufacture for graphite material and graphite machined products.Q:How can you gurantee the quality?A:We have the most advanced equipments in our Lab and professional quality control team.We can gurantee each batch of the product with the stable quality.Q:Can you offer samples?A: Yes, we offer samples to testQ: Delivery time?A:Around 10 days.
