A Few Common Sense Tips for Selecting Industrial Lubricants—Let’s Take a Look!

The selection of lubricating oils is a crucial step in the use of lubricants, serving as the key to ensuring proper equipment lubrication and fully harnessing the performance of the lubricant. 1. When selecting lubricating oils, one should comprehensively consider the following three factors: (1) The actual operating conditions of the mechanical equipment (i.e., service conditions); (2) The specifications or recommendations provided by the manufacturer of the mechanical equipment; (3) The regulations or recommendations issued by the lubricant manufacturer. 2. Selection of Lubricant Performance Indicators: (1) Viscosity: Viscosity is an indicator used for classifying and grading various lubricating oils, playing a decisive role in quality identification and determination. The viscosity of lubricating oil for equipment should be determined by consulting relevant charts based on design or calculated data. (2) Pour Point: The pour point is an indirect indicator of the low-temperature fluidity of lubricating oils during storage, transportation, and use. Experience has shown that the operating temperature of most lubricating oils must be 5–10°C higher than their pour point. (3) Flash Point: The flash point is primarily an indicator of safety during the storage, transportation, and use of lubricating oils; it also serves as a control parameter during production to monitor the distillation range and volatility of the lubricant. The principle for specifying the flash point of lubricating oils is to leave a safety margin of half the specified value according to safety regulations—meaning the flash point should be at least half higher than the actual operating temperature. For example, since the oil temperature in the sump of internal combustion engine oils generally does not exceed 120°C, the flash point of internal combustion engine oils is set below 180°C. (4) Selection of Performance Indicators: There are numerous performance indicators, with significant differences among various types of oils. Therefore, the selection should be made reasonably, taking into account the equipment’s operating conditions, the manufacturer’s requirements, and the product specifications and descriptions. The goal is to meet both lubrication technical requirements and economic feasibility. Substitution of Lubricating Oils: 1. Different types of lubricating oils each have their own unique or distinctive performance characteristics. Thus, it is essential to select lubricating oils correctly and appropriately, avoiding substitutions altogether and strictly prohibiting random substitutions. 2. Principles for Substituting Lubricating Oils: (1) Whenever possible, substitute with oils of the same type or with similar performance characteristics. (2) The viscosities of the substituting oils should be comparable; the viscosity of the substituting oil should not deviate from that of the original oil by more than ±15%. Preference should be given to oils with slightly higher viscosity for substitution. (3) Substitute with oils of higher quality whenever possible. (4) When selecting substitute oils, also pay attention to the equipment’s environmental conditions and operating temperatures. Mixing of Lubricating Oils: 1. It is best to avoid mixing oils of different grades, from different manufacturers, or between new and old oils. The following oils are prohibited from being mixed: (1) Military special oils and dedicated lubricants must not be mixed with other oils. (2) Oils requiring anti-emulsification properties must not be mixed with oils that do not require such properties. (3) Anti-ammonia turbine oils must not be mixed with other turbine oils. (4) Zinc-containing anti-wear hydraulic oils must not be mixed with anti-silver hydraulic oils. (5) Gear oils must not be mixed with worm gear oils. 2. Internal combustion engine oils often contain a wide variety of additives in large quantities, with varying performance characteristics. Caution is required when mixing oils whose performance characteristics are unknown, to avoid adverse consequences or even equipment lubrication accidents.
