  What should be paid attention to in the detection method of centrifugal fan?

  Misoperation of centrifugal fans is related to personal safety and the orderly development of manufacturing. However, the structure of the centrifugal fan is very complicated, mainly composed of an air inlet, an electric damper, a centrifugal impeller, a motor and an exhaust port. In different situations, the actual effect of the centrifugal fan is different. How to adjust the centrifugal fan to the best condition? First of all, this is a mechanical device that uses the input chemical energy to increase the air pressure and transport the steam in parallel. This is a driven fluid machine. The high-speed centrifugal impeller is used to accelerate the steam body, and then reduce the speed, change the water intake, and convert the mechanical energy into gravitational potential energy. So our inspection of centrifugal fans is very important. So what should be paid attention to in the detection method of centrifugal fan?

centrifugal fan types

  The centrifugal fan allows the motor to be started with extra power or with reduced voltage. The current when the motor is started with extra power is about 5-7 times the extra voltage. The reduced voltage starting torque is proportional to the operating voltage square meter. Use step-down to start.

  At the time of trial operation, check whether the wiring method and the same wiring method are the same; check whether the operating frequency of the switching power supply of the centrifugal fan with the balance of supply and demand, the volume of the electrical components are in compliance with the regulations, and whether the switching power supply is open or in the same position.

  During the trial operation, there were about two people in total, each operating the switch power supply and observing the running status of the centrifugal fan, and immediately shut down the machine for inspection if found to be abnormal.

  During the trial operation of the two-speed centrifugal fan, first start the low-speed gear to see if the rolling direction is appropriate; when starting the high-speed, be sure to restart the centrifugal fan after it is stationary to prevent the formation of power switch jump and motor damage.

  When the centrifugal fan exceeds all normal speed ratios, the input current of the centrifugal fan should be accurately measured, and the operating current cannot exceed its extra voltage. If the extra voltage is exceeded, check the operating voltage that balances supply and demand.

  The extra motor power required by the centrifugal fan means that under the necessary load, it is best to close the gate valve on the inlet or outlet pipes of the centrifugal fan during trial operation, and gradually open the gate valve after operation. Pay attention to the operating current of the centrifugal fan Is the extra voltage exceeded?

  Proper conditioning can improve the high efficiency of the centrifugal fan. Improve people's productivity. During the service life of centrifugal fans, normal protection and maintenance are indispensable for proper conditioning, and learning proper conditioning can make it stronger in operations. Centrifugal fans are dedicated to the sales and solutions of axial fans and centrifugal fans.
