Influencing factors of unclean filtration by vacuum oil filter

       Influencing factors of unclean filtration by vacuum oil filter The vacuum oil filter is designed according to the different principles of the boiling points 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 vacuum pump pulls 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 an inlet pipe to remove larger particles, and then enters the heating tank, and passes through the oil at 40~75℃ after heating. Automatic oil drift valve, this valve automatically controls the balance of the amount of oil entering the vacuum tank. The heated oil is separated into a semi-mist by the rapid rotation of the spray wings. 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 water to be released. 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 filter element, thereby 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. The main factors affecting the work of the oil filter: 1. the oil is not up to standard Insulating oil requires high-precision filtration to achieve a high insulation value, and most vacuum oil filters have much more extensive requirements for impurities. 2. Oil viscosity High-viscosity oil cannot pass through the fine filter of the vacuum oil filter. It can be filtered out if the precision is reduced. However, if the cleanliness of the oil is emphasized and the precision filter is used, the operating cost of the vacuum oil filter will increase. Because the filter element is often clogged, frequent cleaning or even replacement of the filter element is required. 3. increase or decrease the axial pressure Increase the axial pressure of the vacuum oil filter, so that the oil can pass through the filter screen faster, but the filter element is often crushed by this. 4. the oil filter hole is blocked The vacuum oil filter needs to be cleaned frequently to keep the machine clean. The connecting bolts of the motor and the bracket of the vacuum oil filter should be checked frequently to avoid loosening. Lubricating oil should be frequently added to the compression screw nut. 5. Control of oil capacity The vacuum oil filter is working according to the oil filter capacity. After circulating filtering 2 to 3 times the amount of oil, unscrew the oil nozzle and take out the oil sample for testing until it is qualified. 6, too much oil mark When the vacuum oil filter is working, pay attention to the oil level. If there is too much oil in the oil pan, open the oil return valve, drain the oil in the oil pan, and then close the oil return valve.
