The lubrication and maintenance of diesel generator sets is a very important process, but a large amount of inferior oil on the market is mixed with too much moisture, which affects the actual use. First, the oil is heated to 110 to 120 degrees Celsius in a test tube. "PI" signifies water in the oil. If there is water in the oil.

How to identify the authenticity of diesel generator lubricating oil

The oil is heated to 110 to 120 degrees Celsius by indirect heating. When the bubbles in the oil disappear, cool to normal temperature and remove the water. If we unfortunately complain about buying inferior lubricants, we can use the following method to evaporate water.

If the oil has a mild emulsion, use the following method: emulsify the same brand of oil, participate in 1% to 3% of the weight of phenol as an emulsifier, stop stirring and heat to 50 ° C to 80 ° C, and settle for 4 minutes. Hours or longer, after waiting for the oil and water layer, the downstream water is removed and can be used.

If the emulsified mechanism of thickened oil can be treated by air drying method: In the container of emulsified heavy oil mechanism and a clean serpentine heating tube, heating is stopped by saturated steam through a coil, and the temperature of the oil rises to 110 to 120 degrees Celsius, and the container is Clean the air and stop stirring, the water will evaporate. It was not until the essence in the oil disappeared that the recovery returned to a transparent color.

Cargoes with corrosive gases and steam such as acid, alkali, etc. Fire extinguishing devices should be equipped if required. If used indoors, the smoke exhaust pipe must be opened to the outside, the diameter of the smoke pipe must be ≥ the diameter of the smoke pipe, and the pipe connected The elbow failure should exceed 3 to ensure the exhaust smoke circulation, and the pipe should be tilted downward by 5-10 degrees to prevent rainwater intake; if the exhaust pipe is assembled vertically upward, then
