The invention belongs to the technical field of underground coal mine explosion-proof diesel engines, and provides a preparation method for a low-temperature auxiliary starting device of a mine explosion-proof diesel engine. The preparation method comprises the following steps that a heating rod, a base, an explosion-proof shell, an upper fixed seat, a lower fixed seat and a cylindrical tool are machined and manufactured; the base is enabled to be connected with the lower fixed seat, and meanwhile, the heating rod is put into the lower fixed seat; the upper fixed seat is enabled to be fixed tothe upper surface of the base; pouring is carried out until a high-temperature insulating adhesive is sucked out from an outlet B in the lower fixed seat; the upper fixed seat and the lower fixed seat are removed after the high temperature insulating adhesive is cooled and fixed; a positive pole lug plate, a negative pole lug plate and an explosion-proof cable are installed on the heating rod, then the cylindrical tool is installed on the base, epoxy resin is poured, the cylindrical tool is removed after the epoxy resin is cured, the explosion-proof shell is installed, the explosion-proof shell is sealed through a rubber ring, a gasket and a horn-shaped nozzle, and meanwhile, the explosion-proof cable is drawn out. The preparation method for the low-temperature auxiliary starting device of the mine explosion-proof diesel engine is simple and high in precision, and can be widely used in the field of mine explosion-proof diesel engines.
Description
technical field [0001] The invention belongs to the technical field of underground explosion-proof diesel engines in coal mines, and in particular relates to a preparation method of a low-temperature auxiliary start-up device for explosion-proof diesel engines used in mines. Background technique [0002] Most of the coal mines in our country are mostly distributed in mountainous areas. The lowest temperature in mountainous areas is far below -10°C in winter. Trackless rubber-tyred vehicles powered by explosion-proof diesel engines will have difficulty starting at -5°C. Vortex type explosion-proof diesel engines are particularly prominent. Need Artificially using auxiliary equipment to heat the explosion-proof diesel engine or injecting low-temperature starting fluid into the intake pipe to start the vehicle affects the efficiency of the coal mine explosion-proof diesel engine vehicle in winter. In order to solve the problem of difficult starting at low temperature, the groun...
