Technical Field
[0001] The utility model belongs to the technical field of wind turbine dynamic balance debugging equipment, and in particular relates to an impeller integral dynamic balance testing device. Background Art
[0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Range hoods work based on the principle of fluid dynamics. A centrifugal fan installed inside the range hood absorbs and exhausts oil smoke, and uses a filter to filter out some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute, and a motor that drives the impeller to rotate. When the impeller rotates, negative pressure suction is generated at the center of the fan, sucking the oil smoke under the range hood into the fan. After being accelerated by the fan, it is collected by the volute and guided to be discharged outdoors.
[0003] Before the fan is used, the impeller rotation needs to be calibrated for dynamic balance. After the impeller is installed in the volute, the entire volute needs to be dynamically balanced, which results in a long installation and debugging time. Summary of the invention
