Industrial damping energy-saving fan

Abstract

The invention relates to an industrial damping energy-saving fan which comprises a fan body, a chassis, a motor, first fan blades and a dual-mass flywheel device. The fan main body is arranged on the chassis; the first fan blade is coaxially provided with a shaft rod; the dual-mass flywheel device is arranged in the fan body, and the input end and the output end of the dual-mass flywheel device are coaxially connected with an output shaft of the motor and a shaft rod of the first fan blade correspondingly. According to the industrial damping and energy-saving fan, the dual-mass flywheel device is arranged to be connected with the motor and the first fan blades, so that the inherent frequency between the motor and the first fan blades is reduced, and circumferential vibration of the tail ends of the first fan blades caused by resonance generated under the condition that the fan runs at a low speed or the rotating speed is suddenly changed is avoided; therefore, vibration and non-uniform resistance when the first fan blade works are greatly reduced, energy consumption of the fan is reduced, the purpose of saving energy is achieved, the situation that parts in the fan are damaged due to vibration is effectively reduced, the service life of the fan is greatly prolonged, and meanwhile noise of fan transmission is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of energy-saving fans, in particular to an industrial shock-absorbing energy-saving fan. Background technique [0002] The industrial fan is a common industrial machine widely used in industrial plants, logistics storage, waiting rooms, exhibition halls, gymnasiums, supermarkets, etc. as a common industrial machine for space ventilation and personnel cooling. The industrial fan can push a large amount of air to the ground, forming a horizontal movement of the airflow layer at a certain height on the ground, thereby promoting the overall air circulation. The maximum diameter of the large-scale industrial fan can reach 7.3 meters. The streamlined first fan blade manufactured by aerodynamic principles and advanced technology can drive a large amount of air with only 1.5KW, and generate a large area of ​​natural breeze system, which plays a role in ventilation and ventilation. Dual function of cooling. Compare...

Problems solved by technology

[0003] However, there are often large-scale equipment in operation in industrial plants and other places, and large-scale equipment produces strong vibrations under operating conditions, especially in places such as construction sites, where the vibration amplitude is greater, but the shock resistance of industrial fans themselves is poor; the shock resistance performance is poor A small fan will cause the first fan blade to be subjected to non-linear or uneven resistance, which will increase the energy consumption of the motor and make the internal parts of the fan easily damaged
