It mainly affects equipment. Generally, refineries do not require high acid value, but customers who buy refined oil will not buy oil with high acid value.
1. The high acid value of the oil product corrodes the unit and reduces the service life of the equipment;
2. When the acid value of transformer oil rises, the conductivity of transformer oil will be improved and the insulation performance of oil will be improved. When the operating temperature is high, the solid fibrous insulation materials will age, especially the low molecular acid content will increase. When there is water in the oil, the insulation level of the electrical equipment will decline, and the operating life of the equipment will be shortened.
3. The increase of the acid value of engine oil indicates that the oil quality is aging. The naphthenic acid soaps and other substances formed in the oil can promote the emulsification of the oil, damage the lubricating performance of the oil, cause wear and heat of the machine parts, and affect the safe operation of the equipment.
4. The increase of acid value of fire-resistant oil during operation will reduce the volume resistivity of fire-resistant oil, cause corrosion of servo valve and threaten the safe operation of the unit.
