Polycrystalline diamond-bearing technology offers an innovative solution for pumping applications operating in harsh drilling fluid environments.
Our PCD bearings for mud motors in downhole drilling tools and other bearing applications.
Examples include drilling turbines, mud motors, and other down-hole rotating tools. There are two main types: PDC radial bearing, and PDC thrust bearing.
High thermal conductivity: It can reduce the local extreme temperature that causes bearing degradation and avoid damage to bearing materials caused by high heat generated during bearing startup or shutdown.
High Load: Can operate effectively at a fairly high speed and load range.
For example: In some oil and gas drilling, diamond bearings can operate 100-6000 rpm at loads up to 60,000 lbs.
Wear-resistant and high-temperature resistant: Diamond material has an extremely low friction coefficient (friction coefficient is between 0.01 and 0.03) and can operate at high temperatures (the current maximum temperature is 233°C)
High fracture toughness: Bearing materials with excellent fracture toughness reduces the likelihood of damage due to impact loads
High corrosion resistance: not affected by corrosive substances in the application environment, for example, not affected by natural or mud chemicals present in drilling
Simplification: Diamond bearings do not need to be specially lubricated during use.
Since seals and independent lubrication systems are not required, equipment and components can be simplified.
Long life: Because the diamond surface is hard and wear-resistant, it can extend the life of the bearing.
The service life is more than 6 times that of traditional tungsten carbide bearings or other carbide bearings (TC bearings).
