    Lubricant manufacturer -Lubricating oil manufacturer investment - anti lubricating oil:
    Lubricant manufacturer , Brand of lubricating oil , Oil franchise agent What is the function of lubricating oil?

    Lubricating oil is used in various types of machinery to reduce friction, protect machinery and processing parts of the liquid lubricant, mainly for lubrication, cooling, rust prevention, cleaning, sealing and buffering.

    1. Reduce friction and wear, reduce friction resistance to save energy, reduce wear to extend mechanical life and improve economic benefits;

    2. Cooling, the friction heat should be discharged from the machine at any time;

    3. Sealing, which is required to prevent leakage, dust and gas channeling;

    4. Anti corrosion and anti rust, and the friction surface shall be protected from oil deterioration or external erosion;

    5. Clean and wash, and remove the scale on the friction area;

    6. Stress dispersion buffering, load dispersing, shock mitigation and shock absorption;

    7. Kinetic energy transmission, hydraulic system, remote control motor and friction stepless speed change, etc.












    Brand of lubricating oil Label of

    The meaning of SAE label: SAE is the abbreviation of "society of motor vehicle engineers" in English. The label at the back of SAE indicates the viscosity value of lubricating oil, such as sae5w-40, in which w stands for winter winter, while the number in front of W represents the active viscosity at low temperature. The smaller the value, it indicates the low-temperature activity of engine oil, The number at the back of W is the viscosity of oil at 100 degrees. The higher the number, the better the viscosity.

    The meaning of API label: API is the abbreviation of "American Petroleum Association". The label after API indicates the quality grade of lubricating oil brand.

    API oils are divided into three categories:

    1. The initial series of "s" represents the engine oil for oil generator, and the standards are: API SA, Sb, SC, SD, Se, SF, SG, SH, SJ, SL, SM

    2. The initial series of "C" represents diesel engine oil, and the standards are API Ca, CB, CC, CD, CE, CF, Cf-2, CF-4, CG-4, CH-4

    3. When the letters "s" and "C" exist together, it indicates that the engine oil is universal for gasoline and diesel. The meaning of the letter after s or C indicates that: from "Sa" to "Sn", the environmental protection grade of lubricating oil brand will be better than that of the former one. The more letters the letter is, the higher the environmental protection grade is. Most of the oil grades in lubricating oil brands are above SF grade, and the oil with high environmental protection level is "Sn".

    After understanding the label meaning of lubricating oil brand, do you know more about lubricating oil? If you need it, Lubricant manufacturer Welcome to inquire about our brand of lubricating oil.


    The factors causing the aging of lubricating oil include: the influence of gas, the disappearance of additives, the oxidation and decomposition of oil, the evaporation of light components, the influence of solid, liquid and radiation.

    1、 The existence of moisture in lubricating oil will attract the investment of lubricating oil manufacturers. At the same time, it will act with additives in oil to promote its decomposition, resulting in equipment corrosion. Therefore, the main cause of water in lubricating oil is found, that is to say, the main cause of oil emulsification is found. The main causes of water inflow in oil are analyzed as follows: 1

    a. The radial clearance of the shaft seal was adjusted too large, and the leakage steam of the shaft seal ran into the bearing chamber along the shaft, resulting in water in the oil. During unit maintenance, in order to avoid rubbing shaft seal teeth due to over critical speed vibration or rotor thermal expansion during unit maintenance. Generally, the shaft seal clearance is increased when adjusting the shaft seal. In the unit, the leakage of water into the shaft seal is the fundamental reason for the leakage of oil into the shaft seal.

    b. The shaft seal teeth are lodging and the sealing effect is reduced, resulting in water in the oil. In the process of shaft seal radial clearance adjustment, if the shaft seal radial clearance is too small, shell lubricating oil manufacturer makes the shaft seal sharp teeth rub with the rotor due to rotor expansion and shaft system vibration during the start-up process of the unit, and the sharp teeth are lodging and the sealing effect is reduced, resulting in shaft seal steam leakage and steam flowing into the bearing chamber along the shaft.

    c. The excessive steam supply pressure of shaft seal into steam header makes the shaft seal chamber become positive pressure, resulting in shaft seal leakage.

    d. The suction pressure of the shaft seal steam extractor is insufficient, and the suction pipe is blocked, resulting in insufficient negative pressure, which causes the steam to escape along the shaft and cause the shaft seal steam leakage.

    e. Negative pressure, or suction gear box caused by the suction of steam. In addition, the output of the exhaust fan of the main oil tank is too large, which increases the negative pressure of the bearing chamber, makes the shaft seal leak steam, and is easier to enter the lubricating oil system.

    f. The joint surface of the cylinder is deformed and the sealing is not tight, resulting in steam leakage and entering the bearing chamber, so that water is carried in the oil.

    g. Abnormal operation parameters lead to high pressure of cooling water side and oil side pressure of oil cooler, and oil cooler leakage.

    2、 Air dissolved in oil, especially at high temperature, will accelerate the oxidation of oil. In the operation of steam turbine, naphthenic acid soap, colloid and other substances produced due to the gasification and deterioration of oil products are emulsifiers, which make the oil easier to emulsify.

    3、 The emulsification of turbine oil is also related to the performance of additives in the oil. Turbine oil additives are mostly compounds or mixtures with certain surface activity. In the molecular structure of these substances, one end is a non-polar group with lipophilic property, and the other end is a hydrophilic polar group with certain surface activity. Although they are not necessarily water-soluble, they are not necessarily water-soluble, but have the ability of oil-water separation.

    4、 Stir vigorously. When the steam turbine rotates at high speed, the oil and water are stirred intensively and fully, presenting a turbid liquid. At this time, the hydrophilic polar group has the opportunity to fully affinity with water, when the affinity is large, it will be firmly combined with water. And because the lipophilic non-polar group can be dissolved in the oil, the water and oil can be combined together through the action of this substance. Therefore, water cannot be separated from oil at this time.
