Low-temperature auxiliary heating start-up device of explosion-proof diesel engine for coal mine

Abstract

The invention provides a low-temperature auxiliary heating start-up device of an explosion-proof diesel engine for a coal mine, and belongs to the technical field of explosion-proof diesel engine start-up assistance. An explosion-proof diesel engine vehicle is used in a coal mine underground auxiliary transportation system; in winter, the outdoor temperature is low and the start-up is difficult; the explosion-proof engine is frequently selected to run all night; not only is the waste of resources is caused, but also the engine is in an unsupervised state and relatively severe potential safety hazards exist; in the later period, several manufacturers apply a ground glow plug technology to the explosion-proof diesel engine; and although the start-up performance is improved to a certain degree, such a severe fault that the explosion-proof engine is damaged is caused. According to the low-temperature auxiliary heating start-up device of the explosion-proof diesel engine for the coal mine, a low-temperature air auxiliary heating device is additionally arranged behind an air inlet fence, so that the temperature of a fuel mixture can be increased; a low-temperature engine oil auxiliary heating device is additionally arranged on an oil pan; the two auxiliary heating devices are controlled through an ECU device; and consequently, the resistance to all friction pairs in the diesel engine is reduced, the start-up performance of the explosion-proof diesel engine is improved, the waste of diesel oil for the whole-night running of the explosion-proof diesel engine is reduced, and the coal mine safety management is improved.

Description

technical field [0001] The invention relates to the technical field of low-temperature start-up of explosion-proof diesel engines, and more specifically relates to a low-temperature auxiliary heating start-up device for explosion-proof diesel engines used in coal mines. Background technique [0002] The explosion-proof diesel engine vehicles used in the underground auxiliary transportation system of coal mines have a very harsh working environment. Coal mines are concentrated in northern areas such as Inner Mongolia, northern Shaanxi, and Shanxi. In winter, the outdoor temperature is low, and it is very difficult to start the explosion-proof diesel engines. No shutdown, to avoid the difficult situation when starting the next day, the explosion-proof engine is in working condition throughout the night, which not only causes a waste of resources, but also the vehicle engine is in an unsupervised state throughout the night, which is one of the risk factors for coal mine safety p...
