How to use lubricating oil, how to use lubricating oil?

1. Moderate dosage.

Most of the transmission components such as transmissions, reducers, and steering gears of motor vehicles are oil-immersed. If the lubricating oil filling exceeds the specified limit, the stirring resistance of the gear during operation will increase, which will cause power loss and increase fuel consumption. Therefore, the amount of lubricating oil must be moderate.

In addition, some people stuff the inner cavity of the wheel with grease when maintaining and repairing the wheel hub bearings of motor vehicles, thinking that the more grease, the better. In fact, adding too much grease to the wheel hub will have many adverse consequences, one is to increase the running resistance of the bearing; the second is to affect the heat dissipation of the bearing; Third, the grease melted due to high temperature may penetrate into the brake drum and cause motor vehicle brake failure. Therefore, "hollow hub lubrication" should be implemented, that is, only grease needs to be applied on the bearing, and no grease is stuffed in the cavity, which can not only ensure the lubrication effect, but also save 5 grease.

2. Control the viscosity.

In fact, high-viscosity lubricants can increase mechanical friction losses. Especially at start-up, because the oil has poor fluidity at low temperatures, the frictional resistance is large, which increases the power loss and increases the fuel consumption. If a lower viscosity lubricant is used, the friction consumption inside the oil can be reduced without increasing the wear of the parts.

According to the test, the viscosity of the engine oil is reduced by one level, and the fuel saving rate of the engine is 1%-3%. Therefore, lubricating oil with lower viscosity should be used on the premise of ensuring lubrication.

3. The price should be considered.

Some drivers want to save money, often only see the price of oil and immediate maintenance expenses, and ignore the increased repair costs in the future. When choosing a lubricating oil, the quality grade of the lubricant should be selected according to the speed, the size of the load, and the type of gear transmission. The performance indicators of high-grade lubricating oil are superior, so it can significantly extend the service life of the machine and the oil change interval, and reduce the maintenance cost.

Especially when a motor vehicle is fully loaded for a long time and works in poor road conditions, it is best to use a lubricant quality grade that is one grade higher than that specified in the manual.

The correct use of lubricating oil plays an extremely important role in improving the operating performance of the unit, prolonging the service life of the unit, and saving economic expenses. Therefore, it is necessary to pay attention to the following when using it.

1) Regular inspection and timely replacement.

With the passage of time of the machine, the lubricating oil in the refrigeration system will continue to change qualitatively, so regular sampling and laboratory analysis, or color and phase comparison inspection, when the oil quality changes to a certain extent, it should be replaced in time. Under normal circumstances, the lubricating oil in the refrigeration system should be changed once a year.

2) Oil change requirements.

Look for the brand of new oil change, it is best not to easily change the brand of refrigeration oil, and it is strictly forbidden to use general engine oil instead of refrigeration oil.

Before replacement, all the oil in the system is released, and some new oil is added, and all the old oil remaining in the system is washed and released, so as to prevent the original oil from destroying the performance indicators of the new oil and affecting the service life of the unit.

When changing the oil, try to drain the remaining oil from the oil cooler. Thoroughly remove sediment and rust in the oil tank and air extraction device, and disassemble, inspect and clean the oil pump and filter to ensure that the replaced lubricating oil is clean and pure, and well lubricated.

3) Precautions to be taken when using the product.

During the shutdown of the unit, when the lubricating oil and refrigerant coexist in the system, the oil lubricating oil should be energized and heated to keep the oil temperature within the specified range.

In winter, when lubricants and refrigerants coexist within the system, how they are managed should be determined by the type of aircraft. Centrifugal chillers, especially centrifugal chillers with R11 as the refrigerant, should keep the electric heater energized to stabilize the oil temperature within the specified range. The screw and piston chillers can not be energized to the electric heater, and then turn on the power supply of the oil heater before use, heat for 24h, and then start the machine.

Nano lubricants are BAI in atomic, molecular DU

The friction and wear behaviors and lubrication behaviors at the relative rotating interface are studied at scale, and the microscopic friction and wear capacity is revealed.

The discipline of designing and preparing lubricants and friction-resistant materials on the nanoscale. It is sent out with the development of nanoscience and technology, and is the most active in the field of tribology research since the 90s, and it is also the most cutting-edge content in the intersection of materials science and tribology. It is driven by the need for high-tech development, and the continuous emergence of modern testing technology has also promoted the development of nanotribology.

Many tribological problems in high technology put forward higher requirements for anti-wear, anti-friction and lubrication. However, the inorganic nanoparticles have poor oil solubility, and the nanoparticles are generally dispersed in the base oil by the action of dispersants or with the help of strong stirring and ultrasonic dispersion. However, due to the small particle size and high surface energy of nanoparticles, the dispersion and stability of nanomaterials in lubricating oil have become one of the main problems limiting their application in lubricating oil additives.

The selection of surface modifier should not only consider its oil soluble dispersibility and stability, but also consider the good tribological properties of the surfactant in the oil after desorption. At present, the main surface modifiers used are: dialkyl dithiophosphoric acid (DDP), alkyl phosphate vinegar, stearic acid, oleic acid, EHA, N-containing organic compounds, etc.

I have personally done destructive testing with Compton nanolubricants. The test car was a dilapidated Yamaha Swift Light 150 water-cooled** car (license plate number Yu B 93359). The car has been using Zhengzhou's Hengyun lubricating oil after my hand overhaul, after running 40,000 kilometers again, there was a situation of burning oil and smoking, with the consent of the owner, replaced with Compton nano lubricating oil, until the vehicle can not drive--- can barely maintain idle speed, but can not add oil:

Put the oil in the engine and it dries; Disassembling the engine, the cylinder and piston were not strained, but the cam head of the cam was completely worn, the peach-shaped part was almost smoothed, the entire peach-shaped cam was almost round, and the rocker arm had no obvious signs of wear and burn. This shows that the effect of nano lubricating oil is still good, so some friends may ask why the cam is completely worn? This is because the overhaul is an ordinary cam used, and the quality is average, almost iron, and there is no rigidity.

My own HK250 also used Compton nano oil after replacing the cam rocker, and after driving 5000 kilometers, I checked the cam rocker part, showing a normal mirror working surface with no wear marks.

As for what the manufacturer boasts, it is commercial use, exaggerated. My opinion is that the use of nano lubricating oil must be true, and the oil change mileage can be appropriately extended, and it cannot be used all the time without changing.

Another characteristic of nano lubricants: the permeability is very strong, and the gaskets and oil seals on the engine will leak if they are slightly defective.

Purely practical experience, not a manufacturer gunner. I am not responsible for any loss caused by your use of other nano lubricants.

1. The principle of mixing 1) In general, mixing should be avoided as much as possible, otherwise it is difficult to accurately examine the quality of oil products. 2) Oils can be mixed under the following conditions: The quality of similar products is basically similar, or high-quality oil is mixed with low-quality oil and is still used in the original use of machinery and equipment.

It is necessary to adjust the viscosity and other physical and chemical properties of the oil, and use different grades of the same oil to mix with each other, such as HL-32 and HL-68 hydraulic oil blended into No. 46. Different types of oils, if you know that the two kinds of mixed oils are without additives, or one of them is without additives, or the two oils are added with additives but do not react with each other, they can generally be mixed, but the quality of the high-quality oil will be reduced after mixing. 3) For oils that do not know the performance, if they really need to be mixed, it is required to do a mixing test before mixing (such as taking two oils to be mixed with 1:

1. The volume ratio is mixed and heated and stirred evenly), observe whether the mixed oil has abnormal phenomena such as peculiar smell or precipitation, if it is found that the peculiar smell or precipitation is generated, it can not be mixed. If there is a conditional unit, it is best to determine the main physical and chemical properties of lubricating oil before and after mixing. 4) Pay attention to the use of mixed oil.

2. Changes in physical and chemical properties after mixing 1) Changes in viscosity After mixing two lubricating oils with different viscosities, the viscosity changes, and the range of change is always between the viscosity of the two oils, but it is not a simple arithmetic mean. The viscosity of the two oils is known, and to obtain a mixed oil based on the viscosity between the two, the blending can be carried out according to different blending ratios, and the proportion can be calculated by the following formula: logn=vlog + v log, v, v--the volume of oil A and oil B (to replace 100%, i.e., v+v =1); the viscosity of oil A and oil B at the same temperature (mm2 s); n - viscosity of blended oil at the same temperature (mm2 s). 2) The change of flash point The flash point of the two lubricating oils is mixed, and the flash point will also change, which can be calculated by the following formula P = (XAPA+XBPB+F) 100 formula P - the flash point of the mixed oil is required; xa - the proportion of a kind of oil; PA – the flash point of a type of oil; xb - the proportion of b oil; PB – the flash point of oil B; f - is the harmonic derivative, which is determined according to the data of a and b.

Hello, I am glad to answer for you that most of the transmission components such as transmission, reducer, and steering gear of motor vehicles are oil-immersed. If the lubricating oil filling exceeds the specified limit, the stirring resistance of the gear will increase, which will cause power loss and increase fuel consumption. Therefore, the amount of lubricating oil must be moderate.

When maintaining and repairing motor vehicle wheel bearings, stuff the inner cavity of the wheel with grease, believing that the more grease, the better. In fact, adding too much grease to the wheel hub will have many adverse consequences, one is to increase the running resistance of the bearing; the second is to affect the heat dissipation of the bearing; Third, the grease melted due to high temperature may seep into the brake drum and cause motor vehicle brake failure. Therefore, hollow hub lubrication should be implemented, that is, only grease needs to be applied on the bearing, and there is no need to stuff grease in the cavity, which can ensure the lubrication effect.

Summary. Dear, there is; When adding engine oil, pay attention to the consistency of the added oil and the engine oil as much as possible, and avoid mixing different brands and varieties of engine oil. Lubricating oils include mineral lubricants, synthetic lubricants, semi-synthetic lubricants, etc.

Lubricants consist of hydrocarbons extracted from natural gas and **. There is no clear definition of synthetic oil internationally. Most lubricants contain PAO, which is known as synthetic motor oil.

Pro, the way of using lubricating oil; After stopping the ignition for about ten minutes, pull out the oil dipstick and wipe off the oil stains on the dipstick with a cloth. Insert the dipstick back into the dipstick tube, pull out the dipstick again, and check the oil mark on the dipstick. In general, the oil stain should be between the upper and lower engraved lines of the dipstick, and the middle line should be on the upper side; If the oil stains of the fruit are below the bottom line, it means that the oil volume is insufficient, and the oil dipstick should be constantly pulled out to observe the refueling situation.

1. Disassembly and cleaning: disassemble the screws, gaskets and oil seals required to disassemble the parts, clean the surface of the parts with clean closed solvents and rags, and remove the oil and dirt from the source of the pants. 2. Accessories installation:

Check that the various accessories that need to be installed are correct, and lubricate the surface of the mounting accessories with lubricating oil to reduce friction between the parts. 3. Lubrication: Use lubricating oil as needed, apply lubricating oil at lubrication points (such as bearings, sliding surfaces, etc.), and make it fully penetrate to reduce friction.

4. Cleaning: Use a cleaning oil rag to clean the lubrication parts or surrounding surfaces to prevent the influence of foreign impurities on the lubrication effect. 5. Inspection:

Check the lubrication area to ensure that the lubricating oil is evenly distributed and sufficient to ensure that the lubrication is effective and the fruit is cracked.
