How to debug the centrifugal fan performance in order to achieve the best

The last one we talked about the fan electrical industry will reshuffle the cards, so we need constant innovation, developing new products can not be eliminated, and today we explain how to debug the centrifugal fan in order to achieve the best performance.
  1, the fan required generator power is required to determine the conditions for centrifugal fan breeze chassis, air inlet fully open, power is larger. The air inlet fully open to continue to run the generator to protect the risk. The fan test hours is best to open the valve in the fan outlet or inlet trajectory run after valve hastily closed, until you reach the required conditions, and pay attention to the fan running DC above the additional DC.
  2, the fan to reach the deformity speed should be measured fan input DC deformities, the centrifugal fan is running DC is useless to override its additional DC. If the running DC override its additional DC voltage should be confiscated need whet her deformity.
  , Two-speed fan test hours, you should start low speed, accuracy confiscated filled position; must wait to start high-speed fan movement after launch, to prevent high-speed reverse shrouded sparked switches tripping and generator damage.
  4, this number of the trial placement of not less than two, a master power,air grille one person to inspect the fan operation, I found extremely signs of immediate stop raids; the first to raid shrouded location accuracy; fans at the end of operation, it should be immediately confiscated each phase running DC balance , DC is above the additional DC; if abnormal signs should be down to the raid. Run for five seconds, stop the raids fan incomparable signs to confirm that no extremely signs switched.

&nbs p; 5, the centrifugal fan try working hours should be carefully browse product annotated book, raid received a report that approach is consistent with receiving the report, map; should be carefully raid event of the need to fan power voltage are consistent with the provisions of power is phase or in phase, the catering The material components of quantitative match requirements.
  6, the fan allows full voltage starter or step-down automatically, it should be noted, DC full voltage start about 5-7 times the additional DC voltage starting torque and voltage is inversely proportional to the square, when the grid quantitatively insufficient, should receive the reduced voltage starting.
