The impeller's inertia is much larger than when it is static

 Electric. The direct connection drive is directly connected by the motor and the Ruz Drum fan through the coupling, but it cannot change the speed of the fan and the air volume of the fan. This connection method avoids the replacement and adjustment of the triangular belt, improves mechanical efficiency, supporting facilities, supporting facilities The motor is a level 4 motor and a 6 -level motor. 

The specifics depends on the pressure and air volume of the Rocky fan needed by the customer. Dive transmission: Advantages: The range of the fan is large, and the traffic is closer to the application needs. Disadvantages: The transmission requires tight force to add additional force to the fan shaft end. Direct transmission: Advantages: The fan shaft has no side force, and the transmission power can be great.

 Disadvantages: Directly connect with the motor, less speed can be optional. In most cases, the fan displacement is too large, and the bypass pipeline is required to be empty, and the power consumption is wasteful.I do n't know if you have encountered the problem of turning the Rogez Drum Fan. Although this situation is rare, it still exists. 

The specific reason is to share with you below! Two quotes are often inverted by other spare fans due to the strict imported leaves. The reversing of the drumming fan is because the rotation direction of the impeller is the opposite of the rotating magnetic field of the motor nail. The starting current is large, and the impeller's inertia is much larger than when it is static. 

The current and time are more, so the inverted turning fans cannot be inverted. In order to start the reversal fan, we must first let the reverse impeller be restrained. For example, add a baffle to the entrance of the reversal fan, or use external forces to prevent the impeller from rotating, and then start.
