Working principle of vacuum oil filter

The vacuum oil purifier is designed according to the different boiling points of water and oil. It consists of a vacuum heating tank fine filter, a condenser, a primary filter, a water tank, a vacuum pump, an oil drain pump and an electrical cabinet. The vacuum pump draws out the air in the vacuum tank to form a vacuum. Under the action of atmospheric pressure, the external oil enters the primary filter through the inlet pipe to remove larger particles, and then enters the heating tank. After heating, the oil at 40~75 ℃ passes through. Automatic oil float valve, this valve is to automatically control the balance of oil in and out of the vacuum tank. The heated oil is separated into a semi-mist by the rapid rotation of the jet wing, and the water in the oil is rapidly evaporated into water vapor and continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled and then returned to the original water and released. The oil in the vacuum heating tank is discharged into the fine filter by the oil discharge pump to filter out the particulate impurities through the oil filter paper or filter element, so as to complete the vacuum oil filter quickly. The whole process of removing impurities, moisture and gas in the oil makes the clean oil drain out of the machine from the oil outlet.
