Automatic control method for vacuum oil injection

The invention relates to an automatic control method for vacuum oil injection, which comprises the following steps of: acquiring temperature values of oil in an oil tank and a vacuum oil filter by using a temperature sensor, acquiring a deformation value of the oil tank by using a deformation sensor, and receiving and storing the temperature values and the deformation value by using a PLC (Programmable Logic Controller) control system; the PLC control system controls operation of the vacuum unit and the vacuum oil filter according to the temperature value, the deformation value and the technological process, and the audible and visual alarm gives out warning, alarming and dangerous deformation prompt information according to the temperature value and the deformation value. And the PLC control system displays the temperature value, the deformation value, the operation states of the vacuum unit and the vacuum oil filter, the process flow information and the alarm information in real time.
