Abstract

The invention discloses a large-air-volume energy-saving silencing type induction fan. The large-air-volume energy-saving silencing type induction fan comprises a shell, a volute arranged in the shelland an impeller arranged in the volute, a first air inlet is formed in one end of the shell, a first air outlet is formed in the other end of the shell, and a driving motor used for driving the impeller to rotate is arranged at the top of the shell. A first cavity is formed in the side wall of the shell, the first cavity is filled with a silencing layer, and a guide assembly capable of pulling the silencing layer to move in the first cavity is arranged in the first cavity. A cover plate is arranged in the first cavity. Under the arrangement of the silencing layer, vibration noise generated bygas flowing is absorbed, noise generated when the fan works is effectively lowered, and the influence of the fan on the outside is reduced.

Description

technical field

[0001] The invention belongs to the technical field of fans, in particular to a large-volume, energy-saving and noise-absorbing induction fan. Background technique

[0002] The induced fan is to send the fresh air supplied from outside to the required area through several indoor induced fans step by step, and to send it to the required area under the condition of no air duct, and at the same time induce the exhaust gas tissue to be discharged from the exhaust fan. It is a kind of to cost-effective ventilation. It is mainly used for ventilation and air conditioning in large-volume ventilation places such as parking garages, subway depots, joint maintenance warehouses, sports and commercial venues, and large factory buildings; since no ventilation ducts are used, the operation mode of the induction fan system can be adjusted According to different ventilation needs or smoke exhaust requirements, the intelligent control system can be used to change the organiza...
