Downhole Mud Motor
As a Downhole tools, Downhole Motor is widely used in Various drilling projects, such as: Vertical Drilling, Directional Drilling, Horizontal Drilling, Coring Drilling, Reaming Drilling, Drilling Tunnels though and etc. Downhole Motor with strong technical performance can increase the working efficiency and increase the drilling economic efficiency.
Downhole Motor is composed of four assemblies of by-pass valve, motor, coupling assembly and drive shaft.
The drilling mud from the Mud pump enter to the motor pass the Bypass Valve, drilling mud get the pressure difference at the output of the motor, the pressure difference push the rotor to rotate, by this way, transfer the torque and speed to the Drive Shaft and drill bits. The motor technical parameters decide the performance of Downhole Motor.
Tungsten Carbide Radial Bearings for Downhole Motor
Downhole Motor is one of the most widely used downhole power tools in oil drilling industry. The Tungsten Carbide Radial Bearings is located in the transmission part and it is a key component which affects the service life of the Downhole Motor. Tungsten Carbide Radial Bearings for Downhole Motor is divided into inner and outer bearing bush. The inner bush is matched and locked with the drive shaft. The outer bush is assembled with the casing of the Downhole Motor. The two parts connect together to get a working surface. It is mainly used for convert the torque and speed of the Downhole Motor passed to the drill bits. During the working process, the Tungsten Carbide Radial Bearings for Downhole Motor is subjected to the axial and radial forces of the Universal Coupling Assembly and the drill bit, and the inner bushing tends to move eccentrically around the outer bushing. The normal failure mode of Tungsten Carbide Radial Bearings for Downhole Motor is cylindrical layer wear. Due to the long-term erosion of sand-containing well fluids, it is required to have good wear and corrosion resistance. With the High temperature furnace sintering process, ZH Tungsten Carbide Radial Bearings sintered body, tungsten carbide powder and hard alloy together.
Advantages of ZH Tungsten Carbide Radial Bearings for Downhole Motor
- Strong anti-wear performance
- Strong erosion resistance
- High hardness
- The sintered layer is firmly bonded to the steel body
- No peeling off block phenomenon
- Lifespan can reach more than 300 hours
Axial Bearing for Downhole Motor
Axial Bearing for Downhole Motor is designed with different pressure angle, and special treatment on the surface to make it more abrasion in the working state. ZH has different types of Axial Bearing for Downhole Motor, such as: Thrust Bearing Stack, Multi-Stage Cylindrical Roller Thrust Bearing, PDC Bearing.
Advantages of ZH Axial Bearing for Downhole Motor
- ZH Axial Bearing for Downhole Motor has High hardness.
- ZH Axial Bearing for Downhole Motor has Thermostable performance.
- ZH Axial Bearing for Downhole Motor has Strong wear resistance.
- ZH Axial Bearing for Downhole Motor has Strong corrosion resistance.
- ZH Axial Bearing for Downhole Motor has long service life, reduce the Drilling cost.
