After chamber 206, after resistance coil heats, temperature is increased and is controlled at 65-75 DEG C cold oil, since temperature raises the production of oily viscosity
Raw huge decline, mobility enhance rapidly.Resistance coil after being powered simultaneously generates electromagnetic field, under the magnetic force, deep fat
In metallic particles or impurity containing metal moved along magnetic line of force direction, 209 table of permanent magnet is pushed under electromagnetic force
Face absorption is fixed, and realizes the separation of metal impurities.At this point, carrying the deep fat of nonmetallic inclusion from electromagnetic heating filter 2
Oil outlet 203 is discharged, and enters in centrifugal filter 1.
The operation principle of centrifugal filter：After hot oil medium enters centrifugal filter 1, rotor starts rotation, filter core 109 carried out
Filter, under the centrifugal force and filter core double action that rotor generates, nonmetallic inclusion and remaining metal impurities are by further from warm
It is filtered out in oil.When 109 pressure difference of filter core exceeds tolerance band, centrifugal filter 1 starts self-cleaning.Deep fat passes through 1 mistake of centrifugal filter
