What's the harm of excessive viscosity of lubricating oil?
What is the harm of too much viscosity of lubricating oil? Viscosity (viscosity) is the primary index of selecting lubricating oil for equipment (lubricant grade and brand). What harm will it do if viscosity is not selected properly? If the viscosity is too large, the fluidity of the lubricating oil will be insufficient, and the parts that need to be lubricated will not be fully wetted. The main hazards are as follows:
1. The internal friction of lubricating oil is intensified, the oil is overheated, the oxidation deterioration of lubricating oil is accelerated, the service life of oil is shortened, and oxidation by-products such as paint film and oil sludge are generated. The friction resistance in the operation of the machine increases, which leads to the increase of energy consumption and the increase of temperature in the operation of the machine.
2. The poor circulation of lubricating oil leads to the insufficient lubrication of equipment, and the oxidation and deterioration of lubricating oil will also lead to poor lubrication, resulting in wear and even equipment failure, and shortening the service life of equipment components.
3. It is difficult to cold start when the temperature is low, which leads to dry friction damage of the equipment during cold start.
4. Bubbles are easily generated in the lubricating oil, and the demulsibility (oil-water separation performance) of the lubricating oil is affected
