A few things you have to know about industrial lubricants

Industrial lubricants are a technology-intensive product, which must be guided by technology and service. In the sale of industrial lubricants, lubrication management is a very important subject. Only by doing a good job of lubricating oil management, can we correctly use lubricating oil, exert the technical performance of lubricating oil, ensure the normal operation of equipment, extend the life of equipment, save lubricating oil, save energy, and improve economic and social benefits.

Transport and storage of industrial lubricants

(1) Bulk oil products

1. The container containing and storing lubricating oil must be clean and clean;

2. Transport and storage of transformer oil and turbine oil requires "special tank line"; Other oil products should be according to the internal combustion engine oil, hydraulic oil, Gear Oil three categories of products set up storage and transportation facilities;

3. Special attention should be paid to prevent moisture and impurities during transportation and storage;

4. The storage period of bulk lubricating oil is generally not more than half a year;

5. The density of lubricating oil is about 0.75~0.95g/cm lighter than water and insoluble in water, the flash point (opening) of lubricating oil is generally higher than 150 ° C, which is a flammable item, and the storage and transportation process should pay attention to prevent environmental pollution and fire;

6. Indicate the name, brand, grade, quantity and warehousing date;

7. The same oil produced by different manufacturers can not be mixed in principle. If it is not mixed, the "mixing test" should be done first to confirm that there is no adverse reaction before operation.

(2) Oil products in barrels

1. Oil loading and unloading trucks are strictly prohibited from brutal operation, the height of oil stacking should be appropriate, and the number of layers should not be too much, so as to avoid collapse danger or crush the product;

2. Special attention should be paid to prevent moisture and impurities during transportation and storage;

3. The storage period of barrels of lubricating oil can be longer than that of bulk, but generally not more than one year;

4. Different oil products should be stacked separately and marked clearly with the name, brand, grade, quantity and storage, so as to avoid mistakes during delivery.

Ii. Management of industrial lubricating oil use process

(1) Selection of lubricating oil

Lubricating oil selection is the primary link in the use of lubricating oil, which is the key to ensure reasonable lubrication of equipment and give full play to the performance of lubricating oil.

1. The selection of lubricating oil should consider the following three elements:

(1) The working conditions of the mechanical equipment when it is actually used (i.e., working conditions);

(2) the specification or recommendation of the mechanical equipment manufacturer;

(3) Regulations or recommendations of lubricant manufacturers.

2. Selection of lubricating oil performance index

(1) Viscosity

Viscosity is the index of classification and classification of various lubricating oils, which has decisive significance for quality identification and determination. The lubricating oil viscosity selected for equipment is determined by checking the relevant chart for design or calculation data.

(2) Pour point

Pour point is an index that indirectly indicates the low temperature fluidity of lubricating oil during storage and use. Experience has proved that the use of general lubricating oil temperature must be 5 ~ 10℃ higher than the pour point.

(3) Flash point

Flash point is mainly an indicator of the safety of lubricating oil storage and use, and also an indicator of controlling the fraction and volatility of lubricating oil during production. The principle of the lubricating oil flash point index is to leave 1/2 safety factor according to safety regulations, that is, 1/2 higher than the actual use temperature. For example, the maximum oil temperature of the internal combustion engine oil pan does not exceed 120 ° C, so the minimum flash point of the internal combustion engine oil is 180 ° C.

(4) Selection of performance indicators

There are many performance indicators, and the gap between different varieties is wide, so the reasonable decision should be made based on the working condition of the equipment, the requirements of the manufacturer and the description and introduction of the oil. Strive to meet the technical requirements of lubrication and economic reasonable.

(2) Substitution of lubricating oil

1. Different types of lubricating oil have their own particularities or differences in performance. Therefore, the correct and reasonable selection of lubricating oil is required to avoid substitution, and indiscriminate substitution is not allowed.

2. The principle of lubricating oil substitution

(1) Try to substitute the same type of oil or oil with similar performance.

(2) The viscosity should be equivalent, and the viscosity of the substitute oil should not exceed ±15% of the original oil, and priority should be given to the oil with a slightly larger viscosity for substitution.

(3) The quality is high and low.

(4) When choosing alternative oil, attention should also be paid to the environment and working temperature of the equipment.

(3) Mixing of lubricating oil

1. Different types of brands, different manufacturers, new and old oils should be avoided as far as possible. Mixing of the following oils is strictly prohibited.

(1) Military special oil, special oil can not be mixed with other oil products.

(2) Oil with anti-emulsification performance requirements shall not be mixed with oil without anti-emulsification requirements.

(3) Anti-ammonia turbine oil shall not be mixed with other turbine oil.

(4) Anti-wear hydraulic oil containing Zn can not be mixed with anti-silver hydraulic oil.

(5) Gear oil can not be mixed with worm gear oil.

2. The following situations can be mixed:

(1) Similar quality products of the same manufacturer.

(2) The same manufacturer of different brands of products.

(3) Different types of oil products, the two groups of mixing do not contain additives.

(4) Different types of oil after mixed test without abnormal phenomenon and obvious performance changes.

3. The types of additives added to internal combustion engine oil are large and the performance is different; Caution should be exercised in the mixing of oils with unknown properties. So as not to cause adverse consequences or even equipment lubrication accidents.

Three. Lubricating oil pollution control

Lubrication accidents are mainly caused by pollution in addition to improper selection or use of lubricating oil.

1. The substances that pollute lubricating oil are dust, impurities and moisture.

2. The control of pollution degree is very important for the anti-wear performance of hydraulic oil, turbine oil, hydrostatic oil film bearing oil and high-speed bearing oil.

3. Pollution control measures:

(1) The container for the storage and transportation of lubricating oil must be clean, closed, and not in contact with metals such as copper and tin that are easy to promote the oxidation and deterioration of lubricating oil.

(2) The oil should be settled and filtered before being added to the equipment to ensure that the cleanliness reaches above grade 5.

(3) The refueling container shall not be exposed to the atmosphere, especially the oil container shall not be uncovered.

(4) The oil tank storing lubricating oil should be cleaned regularly and polluted in time.

(5) The oil tank or oil tank is equipped with an air filter breathing apparatus, more than 100 mesh filters and dust caps at the refueling port, do a good job of sealing each part, and set the filter and blowdown valve in the appropriate part of the lubrication system.

4. Transformer oil and other electrical oils have high moisture requirements, and the oil should be changed as far as possible when the weather is dry, and the oil should be added to the equipment immediately after opening.
