The Development ANG Design Of Oil Fever Engineerring

"Oil fever" is in the environment of low winter temperatures, we use a number of technical measures or means of power generation in the diesel locomotive and passenger car using0#diesel oil. In fact, we should use the negative sign of diesel.This is to save and0#diesel oil minus the price difference between diesel fuel, thereby reducing costs.Diesel condensation point depends on his label:0#diesel condensation point is4℃,-10#is-5℃,-20#is-14℃, and their flash point is65℃.Because of these characteristics of diesel, if you want to achieve "Oil fever", it is necessary to maintain the appropriate temperature of diesel fuel above its condensation point.After analysis, if the diesel locomotive and passenger car diesel power generation temperature maintained at10℃, and the diesel tank maintained at about45℃, it can achieve "Oil fever". This can guarantee its security, and to prevent burning or explosion hazards of diesel, also, to ensure that its temperature is lower than the flash point.In the past,"Oil fever" of Harbin, Shenyang Northern Railway Administration, it is used the method of electric heating. It has some problems, such as:"depot heating equipment power (up to295KW), consume a lot of power, making the increase in costs to increase","security risk". To solve these problems, combined with Lanzhou Railway Bureau’s actual situation of depot reform. We can use the nearby boiler heat.The program uses133℃,0.2MPA and above saturated steam. First, we use a heat exchanger, the water becomes110℃,0.2MP saturated water, Second, we use hot water, through another heat exchanger, the temperature of the lower diesel heat to45℃the high temperature hot oil about, This realization of the diesel heating.If you use hot water boilers, hot water boiler can be directly used for direct heat exchange with the diesel. diesel heating can achieve the same technical requirements. Also, you can save a heat exchanger to reduce the part of the investment. BY use of boiler heat.lt successfully implement to the "Oil fever" in Lanzhou section of the vehicle repair, bridge maintenance section.Two years to run. safe, it’s reliable and efficient highlighting. In actual, this system is used very well. The design and development of the engineering characteristics of the "Oil fever":First, using the existing boiler heat to save operating costs and capital investment; second, it becomes simple, efficient, high degree of automation. At the same time, it can be used for solve all aspects of the problem with0#diesel oil in the winter cold weather, and maintain a good flow characteristics. To the normal requirements for the implementation of Northern Railways, It has accumulated experience in similar works.
