Graphite Carbon Blades for Vacuum Pumps

Graphite carbon blades for vacuum pump blades, also known as vacuum pump rotary vanes, are graphite blades installed on the vacuum pump impeller. The graphite blades are driven by the motor to rotate at high speed to compress the air and achieve a vacuum state in the pump.
Graphite carbon blades are currently the main material for vacuum pump blades.

Product Introduction

Graphite carbon blades are currently the main material for vacuum pump blades.

Features

One of the main advantages of graphitic carbon blades is their excellent wear resistance. These blades are made of high-quality isostatically pressed high-purity graphite material and can withstand long-term high-speed rotation without wear or damage. Therefore, it has a longer service life than blades made of other materials, helping to reduce the operating costs of companies that use vacuum pumps for a long time.

In addition to durability, graphite blades also maintain the overall efficiency of the vacuum pump through smooth, efficient operation. This means businesses using graphite vane vacuum pumps can reduce operational downtime, thereby increasing productivity and profitability.

Perhaps one of the most compelling reasons for using graphitic carbon blades in vacuum pumps is their environmental friendliness. Unlike other vacuum pump blade types that are difficult to dispose of, graphitic carbon blades are designed to be easily recycled or disposed of in an environmentally friendly manner.

Overall, if you are looking for a quality, efficient, and environmentally friendly solution for your vacuum pump blade needs, graphitic carbon blades are definitely worth considering.

The role of graphite blades in vacuum pumps

Generally, rotary vane vacuum pumps are equipped with graphite blades, which is one of the accessories to obtain the vacuum source when the vacuum pump is vacuumed. The rotary vane of the vacuum pump will produce friction when the pump body is not running, and it is easy to cause the wear, fracture and expansion of the graphite blades of the vacuum pump without vacuum pump oil lubrication. As a result, the vacuum degree is insufficient, and the vacuum degree cannot go up. Therefore, there are requirements for graphite blade material in vacuum pumps.

The graphite rotor blade material requires high flexural strength, and is not easy to deform and bend when operating under oil-free starting and high inlet pressure; The density is smaller than that of iron, the centrifugal force required is small, the wear of the cylinder wall is reduced, and it is directly meshed with the metal; High temperature resistance; The coefficient of thermal expansion in the length direction is small, which is equivalent to that of cast iron, so the tolerance of this direction can be considered in the design of cast iron, the expansion coefficient in the thickness direction is large, the hardness is high, and the friction factor of oil lubrication is small, and it is wear-resistant and durable under the premise of full lubrication of oil.

When the motor drives the graphite rotor vane pump, the blades are pressed outward against the circular inner wall of the graphite rotor due to centrifugal force. Due to the eccentricity of the graphite rotor at this time, the capacity of the inlet and exhaust sides of the vane pump is different. The capacity of the inlet side becomes larger and the capacity of the exhaust side decreases, so the air flows into the suction chamber and is sent by the graphite blades to the pump outlet, creating a vacuum at the interface of the pump.
