The vacuum oil filter has the characteristics of small size, light specific gravity, convenient movement, low noise, long continuous working time, stable performance and convenient operation. It is an ideal device for filtering water, gas and impurities in transformer oil, turbine oil, engine oil, hydraulic oil and other oils in power plants, power stations, substations, electrical appliances manufacturers, and industrial and mining enterprises. Vacuum oil filters can be used for on-site filtration and replenishment of various oil-immersed transformers, oil-immersed current transformers, voltage transformers, turbine oil, engine oil, hydraulic oil, lubricating oil and oil-free relays. It can be used for on-site hot oil circulation drying of the above-mentioned equipment, especially suitable for oil-immersed current and voltage transformers and oil-free circuit breakers. This machine can be used for on-site vacuum oil filling, oil replenishment and equipment vacuuming of sealed oil-immersed equipment. This machine can also be used for the regeneration and purification of slightly degraded transformer oil, so that its performance can reach the standard of qualified oil.
The working principle of the vacuum oil filter: The vacuum oil filter is designed according to the different boiling point of water and oil. It consists of a vacuum heating tank fine filter, condenser, primary filter, water tank, vacuum pump, oil drain pump and electrical cabinet.
The air in the tank is drawn out to form a vacuum. Under the action of atmospheric pressure, the external oil enters the primary filter through the oil inlet pipe to remove larger particles, and then enters the heating tank. After heating, 40~75 oil passes through the automatic oil drift valve to automatically control the balance of the oil entering the vacuum tank. The heated oil is separated into semi-mist by the rapid rotation of the jet wing, the water in the oil is quickly evaporated into steam, and the steam is continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled, and then returned to the raw water for discharge. The oil in the vacuum heating tank is discharged into the fine filter by the oil drain pump, and the particulate impurities are filtered out through the oil filter paper or the filter element to complete the entire process of the vacuum oil filter to quickly remove the impurities, moisture and gas in the oil, so that the clean oil is discharged from the oil outlet .
