Summary of common failure analysis of vibrating screen

1. Shaft fracture

The main reasons for the shaft fracture are as follows:

① Long-term metal fatigue.

② The tension of the V-belt is too large.

③The  axis material is poor.

2, transmission failure

①Radial and lateral spacing control is unreasonable, the spacing is too small, it is easy to cause wear between the bay and related components, and ultimately lead to transmission failure.

3, the bearing temperature is too high

If the bearing temperature is too high, it will not directly affect the production immediately. However, if the high temperature is maintained for a long time, it will inevitably have a great impact on the service life of the bearing.

① Working hours are too long.

② Insufficient lubricating oil.

4, constantly simmering oil during use

① The vibration source center line produces motion.

② Internal and external pressure difference.

③ The sealing gland is loose.

④parts are lubricated with thin oil.

5, the screen surface aging speed is faster

The factors affecting the aging of the screen surface are mainly the structural form, material and tension of the screen surface.
