Deformation of the fan blades on the hydrogenerator rotor will have the following effects on the generator.
1. The motor cooling fan blades are broken and the motor cannot dissipate heat effectively. As the temperature increases, the motor becomes hot and the aging of the insulation in the stator is accelerated.
2. If the fan blades are partially damaged, it will cause unbalanced operation, the motor will vibrate, and the stability of the machine base will be damaged.
Physical field simulation scenes related to hydraulic generators include: water flow scene, water wheel blade scene, magnetic field scene, field scene electrical and the mechanical scene.
1. Water flow scenario: To simulate water flow, factors such as speed, pressure, flow rate and direction of flowThe flow of water must be taken into account.
2. Waterwheel blade scene: To simulate the stress of the waterwheel blade, factors such as the force of water flow on the blade, the shape and material of the blade should be considered.
3. Magnetic field scenario: To simulate the distribution and changes of the magnetic field, factors such as the shape, material and magnetism of the magnet must be considered.
4. Electric field scenario: To simulate the distribution and changes of the electric field, factors such as generator structure, material and electrical properties of the cable must be considered.
5. Mechanical scene: To simulate mechanical motion, factors such as speed, moment of inertia, friction and bearing support of the waterwheel must be considered.
Thanks to these simulation scenarios, the productionEnergy consumption, efficiency, speed and other performances of the hydrogenerator under different operating conditions can be predicted. At the same time, the generator design can also be optimized based on the simulation results to improve its performance and reliability.
