    Lubricant manufacturer -Domestic lubricating oil manufacturers - anti lubricating oil (multiple pictures)
    Lubricant manufacturer , Brand of lubricating oil , Oil franchise agent Misunderstanding of lubricating oil adding skills

    Automobile lubricating oil is used frequently in maintenance. Brand of lubricating oil In addition to protecting the engine and reducing the frequency of oil change, the domestic Lubricant manufacturer It can also save fuel costs. In this season, automobile lubricating oil manufacturers should also pay attention not to cause automobile failure due to improper use of lubricating oil. The following is a brief introduction to the misunderstanding of lubricating oil adding skills.

    More oil can be added

    The amount of lubricating oil should be controlled between the upper and lower scales of the dipstick. No matter how good the brand of lubricating oil is, adding too much will increase the stirring resistance of crankshaft connecting rod and increase the fuel consumption.

    Misunderstanding 2: when the oil turns black, it's time to change the oil

    For the lubricating oil without detergent dispersant, it is indeed a sign that the oil has been seriously deteriorated. However, the lubricating oil used in modern automobile is generally added with a static decomposition agent. This kind of lubricating oil is easy to turn black after using for a period of time, but the oil is not completely deteriorated.

    Misunderstanding 3: lubricating oil is often added without changing

    It is correct to check the lubricating oil frequently, but it can only make up for the shortage of oil quantity, but can not completely compensate the loss of lubricating oil performance. Good lubricating oil brand in the use process, due to pollution, oxidation and other reasons, the quality will gradually decline, and there will be some consumption, so that the quantity will be reduced.

    Error 4: additives are useful

    The real lubricating oil is a finished product with various engine protection functions. The formula already contains a variety of additives. Adding other additives by oneself can not bring extra protection to the vehicle, but easily react with the chemical substances in the engine oil, resulting in the decline of the comprehensive performance of the engine oil.

    I hope the above introduction will help you. After learning the above knowledge, I believe you will treat your car well in the future.












    Mechanism of organic molybdenum

    The mechanism of lubricating and reducing friction of organic molybdenum is mainly related to the polished surface of friction pair. On the surface of friction pair, chemical reaction occurs at each point of high load pressure, which promotes the decomposition of organic molybdenum, and decomposes molybdenum disulfide and some phosphates, sulfides, nitrides, etc. these products are dispersed in the oil solvent, adsorbed and deposited on the friction surface, and molybdenum disulfide forms a film covering the wear resistance So as to reduce friction, anti-wear and lubrication.

    Nitrogen modified organic molybdenum is a kind of physical and chemical reaction film formed on the friction surface of lubricating parts under mild working conditions. Under the harsh working conditions of high speed, high temperature and high pressure, organic molybdenum is decomposed into nano scale molybdenum disulfide chemical reaction film, which is stacked on the metal surface with layered microcrystalline structure. The thickness of each layer is 0.625 nm, and the inter layer distance is 1.32nm. This kind of nano scale chemical reaction film can change the movement mode of metal friction surface from sliding friction to rolling friction, greatly reduce the friction coefficient, double the pressure performance, and have a long-term lasting effect.

    Organic molybdenum additives have been widely used in foreign countries, mainly in the fields of internal combustion engine lubricating oil and turbine engine lubricating oil. Many literatures have shown that organic molybdenum containing nitrogen has synergistic effect on friction reduction and antiwear with these sulfur-containing additives such as detergents and dispersants, extreme pressure agents (sulfurized isobutylene, sulfurized fatty oil, etc.) and phosphite.

    The engine oil is no longer required to be sealed by the new engine oil, which can be used to seal the engine oil more and more. On the other hand, the precise structure of lubricating oil for the lubricating effect of higher requirements, therefore, organic molybdenum additives such as attention and praise.



    The factors causing the aging of lubricating oil include: gas influence, additive disappearance, imported lubricating oil manufacturer, oil oxidation, decomposition, light component evaporation, solid effect, liquid influence and radiation effect.

    1、 The existence of moisture in the lubricating oil, the lubricating oil manufacturer, at the same time, will act with additives in the 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 is adjusted too large, and the leakage steam of the shaft seal runs 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. During the normal operation of the unit, the tightness of the shaft seal is affected, and the steam leakage of the shaft seal runs into the bearing chamber along the shaft, which is the root cause of water inflow in the oil.

    b. The shaft seal teeth are lodging and the sealing effect is reduced, resulting in water in the oil. In the process of adjusting the radial clearance of shaft seal, the radial clearance of shaft seal is too small, which makes the sharp teeth of shaft seal collide with the rotor due to rotor expansion and shaft system vibration during the start-up process of the unit, and the sharp teeth fall down 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. The suction effect of the turning gear or the coupling wheel turns the air blast, causing the local negative pressure in the bearing box and sucking in the 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 all dissolved in oil but not in water, the polar groups have a certain affinity for water at a certain speed, which increases the difficulty of oil-water separation and promotes oil emulsification.

    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, it cannot be separated from oil.
