Technical Field

The invention relates to a centrifugal machine, in particular to a centrifugal machine with long service life.

Background

Centrifuges are machines that utilize centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. The centrifuge is mainly used for separating solid particles from liquid in suspension or separating two liquids which have different densities and are not mutually soluble in emulsion (for example, separating cream from milk), and can also be used for discharging liquid in wet solid.

The transmission motor of the existing centrifuge can deviate after being used for a period of time, so that the motor shaft can be abraded or damaged, and the discharging efficiency is low and the use is not facilitated during discharging.
