Advantages and characteristics of the multi-stage centrifugal fan of Hangzhou AFL Electric Co., Ltd.

  Hangzhou AFL Electric Co., Ltd. Environmental Technology Co., Ltd. is a manufacturer specializing in the production of various types of fans. The multi-stage centrifugal fans produced provide well-equipped control systems. Multi-stage centrifugal fans are widely used in sewage treatment, smelting blast furnaces, coal washing plants, and mines. Flotation, chemical gas production, vacuum and other fields can also be used to transport other special gases. Let's take a look at the advantages of the multi-stage centrifugal fan of Hangzhou AFL Electric Co., Ltd.

centrifugal fan vs axial fan

  Advantages and features:

  1. Compact structure: beautiful appearance, good stability, convenient installation and maintenance.

  2. Smooth operation: The optimized design of the impeller reduces the axial force to a minimum, and there is an efficient impeller, and the static and dynamic balance correction is carried out to make the whole machine run smoothly.

  3. Low noise: When the blower is running, there is no mechanical friction, and reasonable blade formation is adopted to minimize the sound. The noise produced by the multi-stage centrifugal fan is high-frequency noise, as long as there are obstacles, it can be soundproof, so there is almost no noise outside the fan room.

  4. Oil-free machinery: The blower bearings are lubricated with lubricating oil, and the bearing life is more than 2 years. The fan does not produce oil and gas during operation.

  5. Impeller: The impeller adopts a special compound linear shape, which reduces internal leakage and improves volumetric efficiency.

  6. Easy to adjust: the butterfly valve on the inlet side adjusts the flow.

  7. Drive mode: Driven by two-stage asynchronous motor. Depending on the user's power grid, motors of different voltages can be used.

  8. Sealing: Labyrinth seals are installed outside the inlet ring of each impeller, between stages and at both ends of the casing to prevent gas leakage.

  9. Cooling: The exhaust bearing seat has a water-cooled structure. Due to the gradual compression of the gas by the impeller, the temperature of the exhaust casing is much higher than the intake casing. There is an air-cooled or water-cooled device in the exhaust bearing seat to extend the service life of the bearing.

  10. Transmission mode: It adopts coupling transmission. According to different equipment and technology, different transmission modes can also be selected.

  "Practice is the only criterion for testing truth." Through the following cases, we can better understand why our multi-stage centrifugal fan of Hangzhou AFL Electric Co., Ltd. has certain advantages.

  Case 1: Printing and dyeing wastewater treatment project. Jiashan Yongquan Knitting and Dyeing Co., Ltd. used to cooperate with other companies in the past and used other manufacturers' multi-stage centrifugal fans. After half a month of normal use, various problems occurred one after another, and normal aeration could not be carried out and production was delayed. After working with us for 15 years, after re-selecting and rectifying our company, and using our multi-stage centrifugal fan, no problems have occurred so far.

  Case 2: Papermaking wastewater treatment project. The daily wastewater treatment capacity of Fuyang Yongjin Paper Co., Ltd. reaches 5,000 tons. After the cooperation, the multi-stage heart blower of our Hangzhou Aifuluo Electric Co., Ltd. has been running well, with stable aeration and up to standard.>>>MORE centrifugal fan PRODUCTS
