　Now all walks of life use centrifugal fans, because the machinery that can help us to raise the gas pressure and can discharge gas, the equipment is also very widely used in the field to help the industry's ventilation, dust and cooling.

Structure composition.

　① Transmission group: consists of spindle, bearing box, coupling, etc. The spindle is made of high-quality carbon steel; the bearing box is composed of rolling bearings and water-cooled bearings, equipped with thermometer and oil level indicator.

　②Housing: good wear resistance, heat and moisture resistance, galvanized steel plate as a whole or surface spraying, can be lifted out of the rotor after disassembly, easy and reliable maintenance.

③Impeller: the blade is coated with wear-resistant coating, is forward multi-winged circular arc, riveted with the front and middle discs, made of galvanized plate, parts are formed by one press, high precision; corrected by balance, smooth running, low noise, good startability ......

　④Air inlet: the structure is convergent streamline, bolted to the front cover group, mounted on both sides of the fan, with a curved cross-section parallel to the axial direction.

　⑤ Motor: low-noise three-phase asynchronous motor is used to reduce transmission losses and improve the overall efficiency of the centrifugal fan, and the speed can be adjusted with the help of three-phase regulator or frequency conversion to achieve the purpose of flexible change of air volume.

The blade working surface processing into serrated, change the hollow blade for solid blade, blade welding anti-wear block and other methods, these can be in a certain degree to reduce the impeller wear

How to do the appropriate maintenance work for the fan?

2021-09-15

Fan as a common factory equipment, for friends working in the factory will not feel unfamiliar, in fact, the fan because of the frequent and continuous work, so it is easy to have some damage, usually for the fan must do a good job related to maintenance work to

How to choose a low-noise centrifugal fan, which points need to know?
