In seasons, car maintenance is essential. If the car does not do the corresponding maintenance before entering the winter, it will have very serious wear and tear, which is equivalent to the amount of wear for years of more running under normal maintenance. How can we choose the right product for the car? In autumn and winter, the drop in temperature is more pronounced. In the case of low temperatures, ordinary products become thicker and less fluid. As a result, it takes longer to reach the required lubrication area, which makes the vehicle less easy to start and wear. Therefore, in autumn and winter, it is better to choose a product with a lower viscosity of the base oil so as to continue to bring good lubrication to the car engine. Winter and summer oil is preferred First of all, the choice should be based on the requirements of the selection, neither the use of excessively high-grade engine oil on the less demanding nor the use of lower-grade engine oil on the higher requirements. The selection can be increased by one level on the basis of the manufacturer's recommendation, or the performance of the selected synthetic oil can be better. Second, you should try to choose winter and summer oil. No matter how the temperature changes, the oil can maintain a stable lubrication performance and play a better protective role. Again, choose according to the situation. If it is new or in good condition, use less viscous motor oils such as 0W-40, 5W-40, and 10W-40 as much as possible to make the flow faster and reduce wear on startup. Finally, if it is in the hot season or has been worn to a certain extent, we must use high-viscosity oil, such as 15W-50, which is conducive to the formation of a thick oil film, maintain the pressure of the oil, and reduce oil consumption. Do not add too much The more oil is not added, the better. If too much, it will increase the crankshaft's resistance to rotation, reduce the output power, and those excess oil will enter the combustion chamber combustion, causing the vehicle to burn oil, smoke blue smoke, so that fuel consumption increases. After the combustion of the oil, the residue will accumulate on the wall of the combustion chamber, reducing the space of the combustion chamber, thereby reducing the compression ratio of the engine; at the same time, it will also accelerate the wear of the cylinder and the piston, thereby reducing the service life of the vehicle. Therefore, when adding, it must be kept slightly lower than the maximum scale of the oil dipstick; in addition to grasp the oil model, oil change season, performance and many other factors. Do not add additives In general, we do not recommend adding additives to the oil. Because its constituent parts are composed of base oils and additives, its formulation has been subjected to various tests and screening, and the addition of additives may be counterproductive. For example, it contains unique anti-wear additives, and its anti-wear properties have been tested to be 50% higher than the APISM standard. If anti-wear additives are added on this basis, the anti-wear properties may be slightly higher, but they are more likely to occur. Anti-wear additives and additives produce chemical reactions that not only reduce the original cleaning and anti-wear functions, but also increase sludge and coke, affecting performance and service life. Filter paper can be distinguished To identify the advantages and disadvantages, generally pay attention to several points: The first is observation. If the oil is clear and yellow-brown, the quality is better; if the color is cloudy or emulsified, it means that there is more water; if the oil has a burning odor, it indicates that it is oxidized prematurely or mixed with other oils. The second is to check for deposits. The third is that the oil can be dropped on the iron plate or the exhaust pipe above 110°C. If there is a popping sound, the oil contains water. The fourth is to drop the oil on the filter paper and control it with a spot map. Under normal circumstances, good quality oils should be suitable for viscosity, neutralization, oxidation stability, wear resistance and corrosion resistance. At present, there are a lot of fake fish on the market, the owner must be carefully identified, it is recommended to the designated dealers, large brand gas stations or repair shops to buy oil or oil change.
Tricone bits, first created during the Great Depression, represented a significant leap forward in drilling technology. Tricone drill bits are the go-to solution for almost any well digging, from everything to simple water wells to industrial scale oil extraction. Tricone bits come in several different varieties, and can deal with a wide range of different rock formations. Most tricone bits are either Mill Tooth bits, or TCI bits (TCI stands for Tugnsten Carbide Insert), and there is an ideal tricone bit for soft, medium, or hard rock formations. It is important to know the type of formation you are drilling in when selecting a drill bit.
Soft rock formations consist mainly of sand, clay, limestone or shale and are ideal for drilling with Mill Tooth Tricone bits. When working with soft formations you can use either sealed bearing or open bearing mill tooth tricone bits, depending on the scope and duration of your project. Sealed bearing tricone bits are longer lasting, but generally more expensive due to the precision work required to protect the bearings. Open bearing bits, on the other hand, are not as well protected and will wear out more quickly, however they are cheaper to manufacture. Tricone bits designed for soft rock generally have longer protruding teeth, [A" shaped teeth, or chisel shaped buttons. In all cases the teeth will be more widely spaced for tricone bits that are designed with soft formations in mind.
If you`re drilling in calcites, dolomites, hard limestones, and some hard shale you`ll need a tricone bit designed for medium rock formations. You may want a TCI Tricone bit. To better understand why tungsten carbide is ideal it`s useful to know about its properties. First discovered in 1927, Tungsten carbide is an exceptionally strong and hard material, this allows it to withstand higher speeds for more rapid drilling. Additionally tricone TCI bits are much more capable at absorbing the significant amounts of heat generated without damaging the tricone drill bit. Medium formation bits have teeth that are far closer together than what you see with soft formation drill bits. Additionally the teeth are less protruding, although they may still come in a similar range of shapes.
Hard rock formations are hard and abrasive formations usually made up of hard shale, calcites, mudstones, chert, pyrite, granite, quartzite, and cherty lime stones. The difficulties of drilling in this material make a TCI tricone bit all but mandatory. The exceptional hardness and strength of TCI [buttons" for the drill bits allow them to endure very difficult drilling conditions. As with all tricone bits there is an option between sealed bearing and open bearing. Sealed bearing bits are considerably more protected from wear and tear and therefore suitable for much more use before being replaced. Gauge protection can also significantly increase the lifespan of a tricone drill bit. Bits designed for hard formations continue the trend of less protruding teeth placed closer together. The teeth will be very short and placed very closely together. This results in a much slower drilling speed than you would get with medium or soft formation drill bits, however if you are drilling through hard rock strata you don`t have much choice.
Hopefully the above information has given you an idea of which tricone bit is ideal for the various rock formations you may have to contend with. For particularly advanced or ambitious projects you will want to carefully consider the type of tooth, additional kinds of seals, the importance of gauge protection, and estimated duration of the project in addition to the rock formation.
