Six advantages and disadvantages of vacuum oil filter for insulating oil
(1) mechanical filter block type oil filter: low price, low filtration accuracy and easy plugging of filter elements. It is mainly used for the basic oil pumping unit.
Vacuum oil filter: vacuum oil filter machine is also known as vacuum high efficiency filter machine, oil filter machine, vacuum oil purifying machine with small volume, light weight, convenient movement, low noise, long continuous working time, stable performance, easy operation and so on. It is the ideal equipment to filter the water, gas and impurities in the liquid of transformer oil, turbine oil, oil, hydraulic oil and so on in all the power plants, power stations, substations, electrical appliances manufacturing plants, refineries, petrochemicals and other industrial and mining enterprises.
3. Centrifugal oil filter: removal of free water and large particle impurity effect is better, but because of high speed rotation, too loud noise, low safety, now basically do not use.
(4) electrostatic filter oil filter: using the principle of electrostatic adsorption, removal of impurities such as metal and oil sludge, open structure, non blockage, high filtering precision, the ability to remove water is less than the vacuum. However, with the use of automatic temperature control oil and water separator, it can not only remove water well, but also better remove impurities. After heating, the impurity particles are more easily separated from the oil liquid. It is mainly used in the operation of the hydraulic station and the hydraulic test bench for the high cleanliness of the oil liquid.
Magnetic suction oil filter: cheap, small structure, no power, generally used in hydraulic pipeline. However, the scope and purification capacity of the impurity are limited.
Combination of various principles: for a combination of specific work design, but the use of a huge structure, high cost and maintenance costs, the effect is not too significant, so the scope is very small, very limited.
Matters needing attention
1. If conditions permit, the incoming oil of the unit is best connected to the lowest point of the tank so as to ensure the proper filtration of pollutants and water.
2, this machine adopts high efficiency special vacuum separation tower, when the water is more water, the vacuum degree should not be too high, so as to avoid vaporization volatilization too fiercely, even appear the injection phenomenon of the exhaust port of the front stage pump. After a few times of circulation, the vacuum degree can be gradually increased with the decrease of the water in the oil.
