Led outdoor advertising vehicle how to select oil
You should all know the importance of the LED outdoor advertising car engine, and the oil is also the oil that can maintain the normal operation of the engine. The oil used in LED outdoor advertising vehicles is the lubricant that our factory says. The main function of oil is to form an oil film in the components of the engine of the LED advertising car, and it can reduce the friction of the parts. Reduce the degree of wear. The choice of motor oil is very important for LED outdoor advertising vehicles. If the oil is not properly selected, it will not be able to achieve good protection. The consequences will be unthinkable. So how can LED outdoor advertising vehicles have the right choice of suitable engine oil?
1, each year to the summer temperature will reach 35-42 degrees Celsius, so hot weather is simply suffering, but in the LED outdoor advertising engine's internal operating temperature of 100 degrees Celsius when compared, that 3 40 is simply a cloud. When choosing LED outdoor advertising vehicle oil in the summer, you can not worry too much about the temperature effect, you only need to take into account the viscosity of the oil, generally the oil viscosity used in the summer should not be too large, you can select the oil marked SAE40 can.
2, now LED outdoor advertising vehicle oil standards only API and related standards such as SEA, under normal circumstances, the engine oil manufacturer is unlikely to be based on a particular model and then go to research and development of oil. So, when buying oil, someone å¿½æ‚ when you say that this is a professional car oil or only original oil, and so on, then it is best to restrain themselves, because these situations are basically non-existent. The oil on the surface of the package is marked with the original motor oil, most of them are produced by the engine oil manufacturer's agent processing, and there is no difference with the general market opportunities for sales.
3, because the coldest winter will be at minus ten degrees, this temperature will affect the use of LED outdoor advertising vehicle oil performance, so choose the LED outdoor advertising vehicle oil in the winter, you need to choose some Oils with better low-temperature fluidity, if used in the south, can be marked with 5W and 10W engine oils. If it is in the north, it is more appropriate to select 0W engine oil.
Variable Attenuator
CNI provides 3 kinds of variable attenuators for different application.The circular variable attenuator can make the optical density linearly varies around a 0°-270° circle for measuring Laser energy farthest. As for the square one, the optical density linearly varies across the length for measuring laser energy. Also the high power variable attenuator is available for customization.
