CENTRIFUGAL

OPERATING INSTRUCTION

  1. General :
  2. The centrifugal fans for air blowing in factory, restaurant, blast furnace, winnowing of village and combustion place.
    The centrifugal fans have the advantages of great air in volume : power economy, low-noise, stability in operation and high efficiency. Before departure from factury, all centrifugal fans have stood a severe test and enabled to ensure the product quality.

  3. Use:
    1. To avoid burning-out centrifugal fans winding, verify that voltage and frequency at the nameplate must tally with local supply voltage.
    2. Period to switch on, see if the blades touch cylinder wall. When abnormality is found out, seek the causeand eliminate it.
    3. Period to switch on, see if the rotating direction of blades tally with technical specification in order to avioid accident caused by loosening of not locking blades.
  4. Cautions :
    1. Yellow ang green line of single phase is for earth line.
    2. The reliable earthling is necessary to ensure safety during operation.
    3. Never use the centrifugal fans where there have acid or explosive gases.
    4. Replace lubricant in bearings after 1500 hours operating.
    5. Storage :
  5. Preserve the centrifugal fans in clean, dry and ventilated place where have no exist acid, alkali or other erosive gas.
