Common wind turbine bearing failures include

Introduction Common wind turbine bearing failures include excessive bearing temperature rise, abnormal bearing noise, etc. Excessive temperature rise, bearing noise, bearing burnt, etc. are all causes of wind turbine bearing failure.

Common wind turbine bearing failures include

The bearing temperature rises too high, the bearing makes abnormal noise, etc. Excessive temperature rise, bearing abnormal noise, bearing burning, etc. are all causes of wind turbine bearing failure. The main troubleshooting methods include shutdown and inspection in response to abnormalities, regular cleaning or bearing replacement, etc. Bearings for wind turbines mainly include yaw bearing assemblies, blade main shaft bearings, transmission bearings, and generator bearings. The bearing structures mainly include four-point contact ball bearings, crossed roller bearings, cylindrical roller bearings, and spherical rollers. sub-bearings, deep groove ball bearings, etc.

Do the fans have high voltage fans and low voltage fans?

The generator will generate a lot of heat when it rotates to generate electricity. Cold air must pass between the stator and the rotor, so there will be fan blades at one end of the generator. The high-speed fan blades will blow out the cooling air. , there must be a grid-like net (mostly circular and closed) outside it, which is the generator windshield, which protects the fan blades to prevent objects from falling on the fan blades.

Low voltage and high voltage refer to the driving motor of the fan and have no direct relationship with the fan. Smaller motors are driven by 380V power supply, while many high-power motors are designed to be driven by high-voltage electricity, which are so-called high-voltage motors. The current passed by a high-voltage motor with the same power is much smaller than that of a low-voltage motor, which is beneficial to the heat generation and service life of the motor. Some people want high-voltage electric drive. I guess they want you to change the original 380V motor of the fan to a 6000V high-voltage motor (the original 380V motor cannot be driven by high-voltage power supply). If your factory's motor is outsourced, There should be no difference between a low-voltage motor and a high-voltage motor for you. As long as the high-voltage motor you replace has the same speed and power as your original 380V motor, it has nothing to do with the fan. However, it is not ruled out that the journal and center height of the high-voltage motor may be different from the original 380V. In that case, your fan may need to appropriately change the size of the fan hub shaft diameter hole during manufacturing and installation (perhaps the hole diameter of the belt pulley). and motor base height.
