The running state of the centrifugal cooling fan is not only reflected in the use skills and maintenance measures of the fan in the later period, but the focus must not be neglected. Some preparations before commissioning are used to judge the reasonable location according to the application place of the fan and provide a good installation environment And the correct installation position is a crucial step for them to function.
1. First check the working position of the centrifugal fan, the necessary parameters of the fan work and the model of the fan, etc.
2. Jog the motor for trial operation and check whether the rotation direction of the fan rotor is consistent with the rotation direction marked on the nameplate of the fan. If they are inconsistent, it is necessary to switch the position of any two phases of the power cord after the power is turned off and then try again.
3. Before use, read this instruction manual and understand the various requirements and working conditions of the fan.
4. Carefully check whether the electrical system is intact. Whether the wiring is correct, and whether there is loose connection or virtual connection during transportation.
5. Check whether the motor rotates in compliance with the regulations after the motor is wet.
6. The test fan must run smoothly and have sufficient lubrication. The vibration and temperature rise of the fan bearing room meet the requirements before they can be used.
7. Do not put tools or any other items in the position of the main bearing box, ensure that the tools and other items around the equipment should be stored in an orderly manner, and maintain a good relationship and smooth passage.
8. Carefully observe whether the installation and preparation of the fan is in place. Once it is found that any situation that does not meet the installation and use specifications must be resolved in time, otherwise the fan will easily appear in various situations problem.
