Shandong Heli Supercharger Co., Ltd. wishes the motherland a happy birthday, may the mountains and rivers be safe and the country be peaceful and the people be safe!

In fact, speaking of these two supercharging technology is not new, the emergence of turbocharging technology from now has more than 100 years of history, supercharging is earlier, but these two technologies were not provided for cars, the earlier supercharging technology is mainly used for mining and ventilation and industrial boiler intake. Turbocharging is the technology used in the first World War on the aircraft, and later the two technologies slowly entered the automobile industry, with the continuous advance of modern technology, the two have been a hundred years of technology red confusion. When it comes to turbocharging, it will naturally mention natural aspiration, and then produce two gangs, a self-powder and vortex powder, the natural aspiration structure is relatively simple, and turbocharging is equipped with a set of turbochargers on the basis of natural aspiration, which is naturally stronger than self-aspiration in terms of power

1. Marine supercharger uses engine oil for lubrication, the oil needs to reach CD level or above, and must be filtered by full-flow filter, filter size is less than 20u. 2. Turbine supercharger must be lubricated in advance under the following circumstances: downtime is too long or winter; After lubricating oil replacement or repair (including draining lubricating oil). 3. In the engine, within 3 to 4 seconds after starting, the oil inlet of the supercharger needs to display 69+69 kpa(0.7 kgf/cm2) oil pressure. 4, when the engine is running with load, in the Z high torque condition and above, the oil pressure at the supercharger inlet should be in the range of 196-392kpa(2.11-4kgf/cm2), and not less than 69kpa (0). 7 kg force per square centimeter). 5. The inlet temperature of lubricating oil should be lower than 100℃, and the Z height should not exceed 120℃C6. Do not use liquid seals

What condition would the car be in if the turbocharger parts were broken? Let's let Xiaobian explain it to you! Turbocharger accessories blade shaft seal failure phenomenon: total speed of the exhaust gas blue smoke, light when heavy. There is no blue smoke during driving, and the oil is consumed. Second, the exhaust gas recirculation pipe serious blockage fault phenomenon: total speed and driving exhaust blue smoke, refueling is more serious, oil consumption is large. Third, the piston ring, cylinder wall, valve oil seal wear or aging fault phenomenon: the vehicle takes a lot of blue smoke, the turbocharger turbine end has an abnormal sound, the turbocharger turbine end leakage of oil four, turbocharger accessories air duct rupture fault phenomenon: the vehicle fuel door and throttle will have a "pull-up" abnormal sound.

Engineering supercharger has four main advantages :1, improve the engine power. In the case of constant engine displacement, the intake density can be increased to make the engine inject more fuel, thereby increasing the power of the engine. The engine power and torque of the construction mechanical supercharger will be increased by 20% to 30%. On the contrary, under the requirements of the same power output, the cylinder diameter of the engine can be reduced, and the volume and weight of the engine can be reduced. Improve engine emissions. By improving the combustion efficiency of the engine, the turbocharger engine reduces the emission of harmful components such as particulate matter and nitrogen oxide in the exhaust of the engine. It is an indispensable configuration for diesel engines to meet the emission standards above Euro 2, and provides platform compensation function. In some high altitude areas, the higher the altitude, the thinner the air. An engine with a turbocharger can m

Engineering supercharger is the use of engine exhaust gas to drive the turbine. No matter how advanced, it's still a mechanical device. Because it often works at high speed and high temperature, the exhaust gas turbine end temperature of the supercharger is above 600 degrees, and the speed of the supercharger is also very high. Therefore, in order to ensure the normal operation of the supercharger, it is very important to use and maintain it correctly. We should mainly follow the following methods: 1. After the car engine starts, do not step on the accelerator quickly, and the total speed should be three minutes. This is to increase the oil temperature, improve the flow performance, get the turbocharger well lubricated, and then you can increase the engine speed and start driving. This is especially important in winter, when it takes at least five minutes to warm up the car. 2. After the engine has been running at high speed for a long time, it cannot be turned off immediately. The rea

People who buy to install mechanical turbochargers should not be used on cars with turbochargers, and they can certainly be installed on naturally aspirated cars. Since natural inhalation, in the middle of the air intake pipe such a thing, it itself has no power, Z is mostly to change the small direction of the air flow, probably can be understood as the principle of air conditioning in the car to adjust the wind direction, that is, by adjusting the Angle of a set of blades to change the wind direction, it is completely impossible to "pressurize" the speed of the wind through this thing, can only more or less affect and reduce the wind speed. In the intake pipe can only play a negative role of obstruction, which is a small negative effect, but also some, at least these iron sheets reduce the cross-sectional area of the inner diameter of the intake pipe. Be careful when choosing oil. Due to the role of the turbocharger, the air quality and volume entering the combustion chamber

6. Maintenance of the oil seal plate Check the cracks, surface roughness and deformation of the oil seal plate. 7. When the sealing ring is running in the turbocharger, the sealing ring directly has thousands of friction with the relevant moving parts, which will inevitably cause wear. If it is not disassembled, it can still be reliably sealed due to the mutual friction and good coordination. After removal, the thickness of the seal ring can be measured to check for wear. Put the new seal ring into the groove, if the gap exceeds 0.23mm, the oil seal sleeve should be scrapped. The floating bearing retaining ring is a vulnerable seal, and needs to be replaced once it is removed. 8. Air compressor impeller maintenance Air compressor impeller is composed of blade, hub, wheel and wheel cover. When it rotates, the air is compressed under the action of centrifugal force and thrown to the edge of the working wheel

The bearings of turbochargers are usually floating bearings or rolling bearings. High speed turbochargers use floating bearings with high reliability. There is a certain gap between the floating bearing and the rotor journal and the middle housing. In the turbocharger operation, the rotor shaft and floating bearings are all floating in the lubricating oil, and there is no mechanical friction between each other. The lubrication between the rotor shaft and the bearing of the compressor adopts pressure lubrication, and the lubricating oil comes from the rich oil channel of the engine, filtered through the fine filter, and enters the middle housing of the supercharger. If the oil is dirty or deteriorated in use, the floating bearing is not easy to form an oil film, the bearing is easy to be scratched in semi-dry friction, and even overheating causes the bearing to deform or turn blue. If it is scratched, deformed or blue after disassembly, it needs to be replaced. During the inspection, if

Recently, there are often fan messages about turbocharged engines: I heard that turbocharged to about 100,000 kilometers is prone to problems, is this true? How long does it last? Is the maintenance cost high? Today, Tencent, the car to talk about the life of the turbocharged engine. In fact, for the turbocharged engine, the life of the engine itself is relatively long, here is mainly talking about the turbocharged system, this system because of high temperature and high pressure work, so the life of the early product is slightly shorter than the life of the engine part, generally 80,000 to 100,000 kilometers! At present, turbine technology is very mature, so if used and maintained properly, it can basically reach the same life as the engine! The turbocharger is a high-temperature component because the gas that drives it comes directly from the cylinder
