Cabinet centrifugal fan: simple introduction of what to buy tips?

   Centrifugal fan is a mechanical equipment that increases air pressure and supplies steam body with the help of mechanical kinetic energy keying in. It is widely used in natural ventilation, dust discharge and refrigeration of processing plants, coal mines, tunnel construction, FRP cooling towers, cars, ships and buildings. Natural ventilation and induced draft fan for heating furnace and furnace. Refrigeration and natural ventilation in machinery and equipment of air-conditioning systems and electrical products; Grains drying and selection; Wind tunnel air source and hovercraft, such as pumping and propelling. According to the direction of the vapor flow, the centrifugal fan can be divided into centrifugal fan, axial fan, oblique flow (mixed flow) and scattered flow. First, the purchase level of customers in the purchase of centrifugal fans, should choose the products of centrifugal fan manufacturing enterprises with well-known brands, there are two reasons: first, the product quality of centrifugal fans is guaranteed; Second, although the price is likely to be relatively high, the environmental protection and energy saving effect of the centrifugal fan of the brand enterprise is very good, and the application cost is much lower. 1. Only when the centrifugal fan is completely normal can it operate. In addition, it is necessary to ensure that the working voltage is stable, prohibit the phase break operation, and the power supply system must be dedicated line, and temporary line power supply system can not be used for a long time. 2. The natural environment should always be kept clean and tidy, the surface of the centrifugal fan should be cleaned, and there should be no dirt in the inlet and vent. Clear the dust and other dirt in the centrifugal fan and pipe on time. 3. The centrifugal fan should be stored in a dry and impetuous natural environment to prevent the motor from moisture return. When centrifugal fans are stored outdoors, waterproof and rainproof measures should be taken. In the whole process of storage and transportation, the centrifugal fan should be avoided to bump against to prevent the centrifugal fan from being damaged. 4. When the centrifugal fan appears abnormal sound, the motor gets hot seriously, the casing inductively starts, the switch trips and can not be started in the whole process of operation, it should be shut down and checked immediately. In order to ensure safety, maintenance is not allowed in the operation of the centrifugal fan. After maintenance, the trial operation should be carried out for about five minutes, and the operation should be started after confirming that there is no abnormal situation.
