Abstract

The invention relates to the technical field of centrifugal ventilators, and discloses a low-pressure centrifugal ventilator. The low-pressure centrifugal ventilator comprises a centrifugal ventilatorbase. A ventilator shell is arranged on one side of the surface of the upper end of the centrifugal ventilator base, an exhaust port is formed in the surface of the upper end of the ventilator shell,a movable plate is arranged at the lower end of the front surface of the ventilator shell, a connecting base is arranged on the other side of the surface of the upper end of the centrifugal ventilator base, a motor box is arranged on the surface of the upper end of the connecting base, a first rotary shaft is arranged in the middle of the surface of one side of the ventilator shell, a supportingring is arranged on the side, close to the ventilator shell, of the outer surface of the first rotary shaft, and a supporting plate is arranged on the surface of the lower end of the supporting ring.According to the low-pressure centrifugal ventilator, the working stability of the device can be improved, the device can be conveniently and rapidly maintained, the working safety of the device is guaranteed, and then it is guaranteed that wind blown by the device can purify air.

Description

technical field [0001] The invention relates to the technical field of centrifugal fans, in particular to a low-pressure centrifugal fan. Background technique [0002] A fan is a machine used to compress and transport gas. From an energy point of view, it is a machine that converts the mechanical energy of the prime mover into gas energy. [0003] The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. The centrifugal fan is widely used in the ventilation of factories, mines, tunnels, cooling towers, vehicles, ships and buildings. , Dust extraction and cooling; ventilation and induced draft of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household electrical appliances; drying and selection of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc. [0004] An existing low-pressure centrifugal fan has som...
