Why does the fan of the central feeding system not rotate and vibrate excessively?

The central feeding system is designed for the production of plastic products in the injection molding workshop, realizing uninterrupted unmanned continuous molding operation. When using the central feeding system for feeding, the fan often does not rotate and vibrates excessively. What is the reason?

1、 Why does the fan of the central feeding system not rotate?

1. The power supply is not connected and the power cord is loose.

2. Overload is generally caused by air filter blockage, exhaust pipe blockage, and handling collision and rotor leaning.

3. The fan head is damaged or there is foreign matter stuck in the fan.

2、 Why does the fan of the central feeding system vibrate too much?

1. The fan impeller is stable and damaged.

2. The bearing is worn or damaged.

3. The side clearance of the gear is too large, misaligned, and fixed loosely.

4. Foreign objects and dust cause the impeller to collide with the impeller, the impeller and the casing, and the solid bolts are loose.
