Centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Centrifugal fans are widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; cooling and cooling in air conditioning equipment and household appliances Ventilation; drying and selective delivery of grains; air source of wind tunnel and inflation and propulsion of hovercraft, etc.
The lubrication system is an important part of the centrifugal fan. Under normal conditions, it helps to protect the normal operation of the centrifugal fan. Once there is a problem with the lubrication system, the operating capacity of the centrifugal fan will be greatly reduced, even affecting the normal operation of the entire production equipment. Therefore, the lubrication system of the centrifugal fan requires strict protection to ensure that the normal operation of the centrifugal fan and the production equipment are not affected.
Special attention should be paid when choosing the quality of lubricating oil. It is an important guarantee for the operation of the centrifugal fan lubrication system. Cheap lubricating oil mixed with moisture cannot be used.
Different filters are installed in centrifugal fans. Their function is mainly to filter out the debris that enters a part of the external environment of the centrifugal fan lubrication system and some impurities that occur during the operation of the centrifugal fan to prevent them from entering the oil tank. Affect the centrifugal fan and cause equipment wear. The filter needs timely inspection and regular cleaning. The air filter cleaning needs to unscrew the nut and clean the filter sponge inside.
The lubrication system of the centrifugal fan will also show a state of disrepair and aging. When the lubrication system of the centrifugal fan is overhauled, it is necessary to check the aging status of some of its components to ensure that each component is within the normal range of use to ensure the normal operation of the lubrication system . The lubricating oil model of the centrifugal fan lubrication system can be confirmed with the centrifugal fan manufacturer. Different centrifugal fan manufacturers use different types of lubricants.
