"Substitute parts" are used for long
In the use of maintenance vehicles, some drivers use long-term alternatives for "similar" items when they find that some "small pieces" are damaged or missing. In general, “substitute parts†are only suitable for use in emergency situations, and long-term use can easily lead to other vehicle failures. Therefore, the "substitute parts" are not used for long.
1. Bolt, Cork, Rag Replacement Drain switch When the drain switch is damaged or missing, some drivers replace it with bolts, corks, and rags. This is not conducive to the need for winter water discharge of the vehicle and may result in inadvertent cooling water discharge. As soon as possible, an accident with a cracked engine component occurred. Therefore, when the drain switch is damaged, it must be replaced promptly.
2. Asbestos wire or cotton yarn replaces copper gaskets. Copper gaskets are installed on injectors and spark plugs to prevent high-pressure fuel gas from leaking in the engine combustion chamber. It also has good heat dissipation. Some pilots found leaks at the copper gaskets. They did not repair or replace the gaskets, but instead used an asbestos or cotton yarn to wind the leak to increase the seal. It is possible to do this in an emergency, but if used for a long time, the injectors and spark plugs will overheat due to poor heat transfer and will work poorly, and even cause the injectors and spark plugs to sinter; at the same time, they will change the injectors to extend the cylinder head. The height of the bottom plane changes the injection distance of diesel fuel, which is not conducive to the full combustion of fuel.
3. Ordinary bolts instead of special bolts Bolts for engine connecting rods, cylinder heads, fuel injectors, flywheels, chassis transmission shafts, etc., are all special bolts for special machining that can withstand large torques and ensure that the connections are tight and reliable. The use of ordinary bolts instead of long-term use can easily lead to tensile deformation or even fatigue fracture, resulting in mechanical damage.
4. "Coarse" bolts instead of "fine" bolts Some "small" bolts with small pitches have anti-loosening function and are used for more critical connection points. If the "coarse teeth" bolt is used as a substitute, it may loosen and cause the connection to fail due to the lack of anti-loosening function, resulting in failure of the parts to be damaged.
5. The flat pad instead of the spring pad spring pad plays an important role in preventing the loosening of the bolt, and the flat pad has no such function. If flat washers are used instead of spring washers, it is easy to loosen the bolts and cause damage.
6. Different types of plungers or injectors are used instead. Some drivers found that the individual plungers or injectors did not work properly when repairing the injection pump or injector. Due to the lack of accessories of the same type, other commonly used Model accessories instead. Due to the large differences in the diameter, effective stroke, spray cone angle, range, and pressure of different types of plungers and injectors, prolonged use will result in unstable operation of the diesel engine and insufficient power.
7. Large-capacity batteries instead of small-capacity batteries Some drivers use high-capacity batteries instead of the original small-capacity batteries in order to ensure that the vehicle can be started smoothly. This will cause the engine on the locomotive to undercharge the large-capacity battery, so that the battery is in a lossy state for a long time, which will damage the service life of the battery.
8. Different specification models of triangular tape substitutes or uses different types of triangular tapes instead, because the triangular tape length, elasticity, and different contact surfaces of the pulleys cause uneven force, leading to premature damage; at the same time, it leads to fans and pumps. , Pulleys, etc. work poorly or the bearing is damaged early.
9. Non-standard high-pressure fuel pipe substitute When the multi-cylinder diesel high-pressure fuel pipe is damaged individually, there is no replacement of the same type of fuel pipe, and a high-pressure fuel pipe is randomly found to be installed. Due to the change of the inner diameter and the length of the tubing, the amount of oil supplied by the cylinder and the time of the oil supply may be changed, resulting in unstable operation of the diesel engine and reduced power. Therefore, when an individual high-pressure fuel pipe is found to be damaged, the same type of standard oil pipe should be replaced.
10. A variety of oil substitutes or mixed use such as steam engine oil, diesel engine oil, hydraulic oil, transformer oil, etc. can substitute or use each other, which can easily lead to changes in oil properties, which is not conducive to lubrication, cooling, sealing, rust, power transmission needs General gear oil instead of hyperbolic gear oil can lead to early damage of the hyperbolic gear. Hyperbolic gear oil instead of ordinary gear oil will lead to early corrosion and wear of ordinary gears; individual driver diagrams facilitate the use of oil or ordinary hydraulic oil instead of braking. Liquid, these oils have poor resistance to air resistance, which increases the air resistance of the brake line and makes the brake work unreliable.
Hyaluronic Acid Filler Injection can be filled in the space between body's cells and collagen fibers. Nowadays it is widely used as filling material in plastic surgery. Filler hyaluronic acid can also be used to make the contours of the human body, such as nose, abdomen, abundance of chin, abdomen, cheek, etc. The treatment is both simple and safe. Therefor it is becoming one of the most popular micro-shaping materials. Nowadays sexy lips are becoming more and more popular. Many women want to have sexy lips through the plastic surgery. Therefor lip wrinkle filler becomes good choices to many beauties as lips fillers.
