If the high-pressure fan does not rotate, it is necessary to solve the problem from the basic point of the power supply first, and use the elimination method according to the following methods:
1. If the power supply is not connected, or the wire connected is damaged or disconnected, use a power cord that meets the requirements, and it is prohibited to use a power cord that is too thin.
2. Check whether the connector is installed properly, whether it is firm, whether it is loose, whether there is a bad contact, affecting the conductivity, etc. Sometimes, it looks like it is installed, but there is no good contact with the connecting piece, and it will not rotate. In this case Some customers have encountered it before.
3. If the motor is not working, check whether the motor is damaged. Every high-pressure fan of our company will be energized and run for inspection when leaving the factory, so this situation generally does not occur, but it does not rule out that the logistics will be damaged during transportation. It can be checked with inspection tools.
4. The internal impeller of the high-pressure fan is damaged or stuck. If stuck, the motor will make a buzzing sound after power on, but it will not rotate. If the tool fluctuates, it will definitely not be able to be moved.
5. The bearing is damaged and locked, and the fan needs to be disassembled to replace the bearing.
6. If it is a single-phase 220v fan, then the capacitor may be damaged, causing the motor to fail to start, just replace a capacitor.
