Description

Technical Field

[0001] The utility model relates to a cover plate, in particular to a novel fan cover plate, belonging to the technical field of fan accessories. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and deliver gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas delivery machinery in China. The fans usually refer to ventilators, blowers, and wind turbines.

[0003] Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and conveying of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc.

[0004] When the fan starts working, the vibration of the bearing is very small, but as the running time increases, the dust in the fan will adhere to the impeller unevenly, gradually destroying the dynamic balance of the fan and gradually increasing the bearing vibration. Once the vibration reaches the maximum value of 11mm / s allowed by the fan (the maximum allowable value expressed by the amplitude value is as follows), the fan must be shut down for repair (remove dust accumulation and redo dynamic balance). Existing fans need to use fan covers during production. However, most of the existing fan covers are one-piece cover structures made of metal materials, and their overall structural strength and impact resistance are poor, and they are prone to collision deformation, which affects their service life.
