The transportation and storage requirements for smooth oil are:
(1) Bulk oil products
1. Containers containing and storing smooth oil need to be clean and hygienic.
2. The transportation and storage of transformer oil and turbine oil demand "special tank line", other oil products should be set up according to three major categories of engine oil, hydraulic oil, gear oil storage and transportation equipment.
3. Special attention should be paid to avoiding the incorporation of moisture and impurities during the transportation and storage process.
4. The storage period of bulk smooth oil usually does not exceed half a year.
5. The density of smooth oil is about 0.75~0.95g/cm lighter than water and insoluble in water; the flash point (opening) of smooth oil is usually higher than 150 °C; it is a combustible item; the storage and transportation process should focus on avoiding The outflow pollutes the environment and burns on fire.
6. Indicate the name, trademark, grade, quantity and date of storage.
7. The same oil product produced by different manufacturers can not be mixed; if non-mixed storage is not possible, it should be done before the "mixed-pair experiment" to recognize that there is no adverse reaction.
.ǘ) Bottled oil
1. The oil handling truck stops the rough operation; the height of the oil accumulation should be appropriate; avoid the risk of attack or crush the product.
2. Special attention should be paid to avoiding the incorporation of moisture and impurities during the transportation and storage process.
3. The shelf life of barreled smooth oil can be longer than in bulk; but usually do not exceed one year.
4. Dissimilar oils should be separated and marked with clear name, trademark, grade, quantity and warehousing; avoid mistakes when shipping.
Smooth oil application process
ã„’å”¬â”¤è ¡ stealing hard
Smooth oil selection is the primary link in the application of smooth oil; it is the key to ensure the equipment is smooth and fully slick oil function.
1. The selection of smooth oil should be summarized into the following three elements:
(1) Working conditions (ie working conditions) when the mechanical equipment is actually used,
(2) The designation or referral of the manufacturer of the mechanical equipment,
(3) Rules or referrals for smooth oil manufacturers.
2. Selection of smooth oil function target
(1) Viscosity and viscosity is the target of classification and classification of various smooth oils; it has a resolutional meaning for quality discrimination and determination. The equipment is selected with smooth oil viscosity according to the drawing or accounting data to check the relevant chart.
(2) Pour point pour point is the target that directly indicates the low temperature fluidity of smooth oil storage and operation. It has been proved that the application temperature of smooth oil is usually 5~10 °C higher than the pour point.
(3) Flash point flash point is the goal of smooth oil storage and operation is a safe target; together as a target for handling smooth oil fractions and volatility at the time of production. The criterion for smooth oil flash point target rule is to retain 1/ according to safety rules. 2 safety factor; that is, 1/2 higher than the actual operating temperature. If the engine oil tank bottom oil temperature does not exceed 120 °C; therefore, the regular engine oil flash point is 180 °C minimum.
(4) The selected functional targets of the functional targets are more numerous; the distance between the different types of samples is very different; the working conditions of the equipment, the needs of the manufacturer, and the rational resolution of the oil products should be summarized and analyzed. Efforts should be made to satisfy both the smooth skill requirements and the economics. .
(ii) Replacement of smooth oil
1. The slick oils of the different sample types have their own special functions or differences. Therefore, the smooth and oily oil should be used correctly and reasonably; the substitutes should not be used.
2. Guidelines for smooth oil substitution
(1) Try to use the same type of oil or oil near the function.
(2) The viscosity should be appropriate; the viscosity of the substitute oil should not exceed ±15% of the original oil. Priority should be given to the oil with a slightly higher viscosity for substitution.
(3) Quality is low and low.
(4) When choosing alternative oils, we should also pay attention to the environment and working temperature of the equipment.
(3) Mixed use of smooth oil
1. Different kinds of sample kinds of trademarks, different manufacturers, new and old oil should try to avoid mixing. The following oils are sure to stop mixing.
(1) Military special oils and special oils cannot be mixed with other oils.
(2) Oils with anti-emulsification requirements should not be mixed with oils without anti-emulsification requirements.
(3) Anti-ammonia turbine oil must not be mixed with other turbine oils.
(4) Zn-containing anti-wear hydraulic oil cannot be mixed with anti-silver hydraulic oil.
(5) Gear oil cannot be mixed with worm gear oil.
2. The following conditions can be mixed:
(1) The same quality of the same manufacturer is near the product.
(2) The same manufacturer has the same kind of trademark products.
(3) Oils of different types; if they know that the two components are mixed, they do not contain additives.
(4) There are no abnormal phenomena and significant functional changes in the mixed oil samples.
3. Internal combustion engine oil participates in a large number of additives; the functions are different, and it is necessary to keep the problem of mixing the functional oils. It is necessary to avoid the adverse consequences and even the smooth operation of the equipment.
(4) Smooth handling of smooth oil pollution except for the selection or application of smooth oil; the first reason is the pollution.
1. The substances that pollute the smooth oil are dust, impurities, and water.
2. The control of pollution degree is very important for the anti-wear function of hydraulic oil, turbine oil, hydrostatic oil film bearing oil and high speed bearing oil.
3. Ways to control pollution:
(1) The container for storing and transporting smooth oil must be hygienic and sealed; and it is not easy to push copper, tin and other metal touches that are easy to promote smooth oil oxidation.
(2) Sedimentation and filtration should be carried out before the oil products participate in the equipment; ensure that the temperature reaches 5 or above.
(3) Refueling containers are not exposed to the atmosphere; special oil containers are not covered.
(4) Oil tanks storing smooth oil should be removed regularly; timely discharge.
(5) Air filter respirator is installed on the oil tank or fuel tank; filter and dust cap of 100 mesh or more are installed at the fuel filler port; seals of each part are made well; filter and drain valve are arranged in the proper part of the smooth system.
4. The oil for electrical appliances such as transformer oil has high demand for water; it should be changed as soon as the climate is dry. The oil should be added to the equipment immediately.
(5) Monitoring of the use of smooth oil The smooth oil will gradually age and change during the application process. This is an inevitable rule. There are two conditions for aging metamorphosis: one is normal aging metamorphosis, and the other is abnormal due to water pollution. The abnormal transformation of the elements. Monitoring the operation of the smooth oil; timely grasping the skill status of the oil; avoiding the smooth occurrence of the equipment; extending the life of the oil product.
1. Monitoring method
(1) View the operator's performance of the equipment "smooth" five specifications.
(2) Sampling and investigating the appearance of the oil; checking the color, transparency, smell, etc. of the oil.
(3) Regularly carry out the physicochemical objectives such as viscosity, flash point, moisture, acid (or alkali value), etc., which can reflect the quality change of the oil.
(4) There is no laboratory capable of performing water blasting experiments and staining experiments.
(5) Analyze with modern instruments. For example, the infrared spectrometer is used to determine the modification of the additive in the oil; the iron spectrometer or ICP emission spectrometry is used to determine the change of the metal abrasive element in the oil. The instrument analysis is convenient and accurate; for large-scale equipment such as generator sets Smooth handling has a very important meaning.
(6) Smooth oil replacement Smooth oil is used after a period of time (months, years, decades); because of its own oxidation and the influence of external factors in the process of application, it will gradually change; function is reduced or changed; it is necessary to order replace.
1. Determination of oil change time
(1) According to the results of the inspection and identification, the oil change time is determined, but the current difficulty is to compare the shortage of various oil products. (2) According to the recommendation of the smooth oil producer and equipment manufacturer, the actual application experience is replaced. .
2. Oil change matters
(1) It is easy to make oil change resolutions; try to extend the period of use of oil products.
(2) Try to contact the maintenance period to change the oil.
(3) Do not easily waste when changing oil; if the oil quality is good; can be used for a little treatment (such as sedimentation filtration; remove water impurities) and then used or used for non-essential equipment. Waste oil should be collected well to facilitate future Re-dispose and avoid polluting the environment.
Avoid slick oil damage Many oil products of Ankang are harmful to the human body; if the skin is not cleaned and cleaned in time, it can cause dermatitis and phlegm; it can cause rash or skin tumor in severe cases. Incorrect or inhaled in the body; Or pneumonia; severe people can incur cancer; therefore, it is extremely important not to get oil on food; don't get into the respiratory tract; don't get oil or oil on the ground; it's not only bad for the country; Personal hygiene.
Animal experiments prove that refined mineral oil smooth oil is less toxic; however, the addition of additive smooth oil is necessary to pay attention to protection. Even if the new oil is non-toxic; the transformation and pollution will add its damage during the application process; Therefore, we must pay attention to not infecting the skin; especially if it is not inhaled or eaten. If it is not taken care of, it should be cleaned with clean water. The smooth oil replaced by the waste oil has been transformed; it can only be disposed of as waste oil; Oil should be disposed of properly; avoid environmental pollution.
1. These waste oils should be collected and disposed of in unison; buckets or bottles containing smooth oil should not be littered and disposed of properly; avoid adverse effects on the environment.
2. Smooth oil oil after application, especially smooth oil with more additives, is difficult to regenerate. But it can usually be burned as fuel oil.
