What is the working principle of vacuum dehydration oil filter machine?

Dec 30,2022

Vacuum oil purifier is designed according to the principle of different boiling points of water and oil. It is composed of vacuum heating tank fine filter, condenser, primary filter, water tank, vacuum pump, oil discharge pump and electrical cabinet. The vacuum pump pumps 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°C passes through Automatic oil drift valve, this valve is to automatically control the amount of oil entering and exiting the vacuum tank to balance. The heated oil is rapidly rotated by the spray wings to separate the oil into semi-mist, and the water in the oil evaporates rapidly into water vapor and is continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled and then returned to the original form of water to be released. The oil in the vacuum heating tank is discharged into the fine filter by the oil discharge pump to filter out particulate impurities through oil filter paper or filter elements, thus completing the vacuum oil filter quickly. The whole process of removing impurities, water, and gas in the oil, so that the clean oil is discharged from the oil outlet.
