Fuel heating system and control method for railway air-conditioning generator car suitable for alpine environment

Abstract

The invention relates to a railway air conditioner dynamo van fuel oil heating system and control method suitable for a high and cold environment. The railway air conditioner dynamo van fuel oil heating system suitable for the high and cold environment comprises two diesel engine sets and two oil tanks, and further comprises at least two fuel oil heating devices and a controller. The fuel oil heating devices are communicated to the cooling water pipelines of the two diesel engine sets through water inlet pipes and water outlet pipes respectively, the fuel oil heating devices are communicated to the two oil tanks through oil inlet pipes and oil outlet pipes respectively, each water inlet pipe, each water outlet pipe, each oil inlet pipe and each oil outlet pipe are respectively provided with a control valve used for enabling a pipeline to be connected or disconnected, the fuel oil heating devices and the diesel engine sets can be combined freely to work, and heat exchange devices used for oil and cooling water to carry out heat exchange and oil pumps are arranged in the fuel oil heating devices. The railway air conditioner dynamo van fuel oil heating system suitable for the high and cold environment can carry out heating on the fuel oil in the fuel oil tanks of an air conditioner dynamo van ceaselessly, and guarantee the continuous and stable work of a diesel generator, the problem that the fuel oil in the fuel oil tanks cannot flow normally due to the fact that the temperature is too low in minus 60 DEG C extreme low temperature environment in winter can be solved, and energy sources can be saved fully.

Description

technical field [0001] The invention relates to a railway air-conditioning generator car, in particular to a fuel heating system and a control method for a railway air-conditioning generator car suitable for the alpine environment of passenger cars. Background technique [0002] At present, for some passenger cars used in alpine regions, the air-conditioned generator cars are powered by diesel units. The international intermodal bus passes through Siberia. The passenger cars need to operate in the extremely low temperature environment of -60°C in winter, while the diesel engines of the generator cars are non-electric. Therefore, in the design process of the diesel generator set and auxiliary system of the international transport generator car, there is a problem of how to ensure the normal and economical operation of the diesel generator set when the diesel generator set works in the extremely low temperature environment in winter. [0003] At present, railway generator cars...

AI Technical Summary

Problems solved by technology

[0003] At present, railway generator cars use fuel electric heaters to heat fuel oil, but the fuel heating of generator cars operating in alpine regions requires a lot of heat, and the heating capacity of existing electric heaters is far from enough, and If the fuel heating device fails, the fuel system cannot work normally due to the low temperature, and the reliability is poor
