1. Before starting the oil purifier, set the vacuum degree and control temperature. The vacuum degree of the electric contact vacuum gauge is set between -0.07 ~ 0.09mpa according to the different altitude, and the temperature of the temperature controller is generally set at 45 ~ 65 ℃.

2. Open the valve on the intake pipe of the vacuum pump, start the vacuum pump, and pay attention to the rise of vacuum.

3. When the vacuum degree reaches the set vacuum degree, the electric contact is turned on; The oil inlet solenoid valve opens automatically, that is, the oil inlet starts, and the heater is put into use at the same time. (Note: the use of the heater is controlled by the set value of the temperature controller and the two-way control of the oil inlet solenoid valve, that is, the heater can be put into use only when these two conditions are met at the same time.)

4. When the oil level reaches the lower limit of the infrared oil level automatic control instrument on the oil level gauge after the oil enters the vacuum tank, the internal relay contact of the infrared oil level automatic control instrument is turned on, the oil outlet solenoid valve is automatically opened, the oil pump is automatically opened, and the oil outlet begins to discharge oil; 

If the oil level exceeds the upper limit of the infrared oil level automatic control instrument on the oil level gauge, the oil inlet solenoid valve will automatically close and stop oil inlet, so as to avoid oil leakage of the vacuum tank; If the oil level is lower than the lower limit of the infrared oil level automatic control instrument on the oil level gauge, the oil pump will automatically stop oil drainage. So as to ensure the automatic control of the whole oil filtering process.

5. After the machine works normally and the oil circulates for several times, samples can be taken from the sampling port for testing.
