Embodiment Construction

[0023] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0024] The explosion-proof diesel engine cooling circulation system includes the diesel engine main engine cooling circulation system and the exhaust cooling circulation system, that is, two sets of cooling circulation water circuits, which are driven by two water pumps to circulate the coolant, and the coolant is not shared. The two sets of circulating waterways share a fan, and the two radiators are overlapped and fixed together, such as figure 1 shown.

[0025] The cooling circulation system of the main engine of the diesel engine is composed of the cooling structure of the diesel engine, the water pump of the diesel engine, and the main radiator to form a closed circulation water circuit. The outlet of the water pump is connected to the water inlet of the diesel engine cooling structure, the water outlet c of the diesel engine cooling stru...

Abstract

The invention belongs to the technical field of the explosion-proof diesel engines, and specifically relates to a cooling circulatory system of an explosion-proof diesel engine for coal mine. The cooling circulatory system of the explosion-proof diesel engine for coal mine solves the problem that the existing cooling circulatory system of the explosion-proof diesel engine is poor in applicability and capable of affecting the operation of the body of the diesel engine. The cooling circulatory system of the explosion-proof diesel engine for coal mine comprises a diesel engine host cooling circulatory system and an exhaust cooling circulatory system, namely two independent cooling circulatory water routes in which the cooling liquid is driven to circulate by two water pumps, respectively, a fan shared by the two cooling circulatory water routes and a hydraulic driving mechanism for the fan. The host and the exhaust system of the diesel engine can be cooled more rationally by the cooling circulatory system, and the high-temperature phenomenon, and the problems of whole device not available and even diesel engine damage due to high temperatures are avoided.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof diesel engines, and can be applied to inflammable and explosive working environments powered by diesel engines such as coal mines, metal mines, petrochemicals, and food processing, and specifically relates to a cooling circulation system for explosion-proof diesel engines used in coal mines. technical background [0002] The surface temperature of the explosion-proof diesel engine system used in coal mines needs to be lower than 150°C, so the cooling circulation system needs to cool the exhaust system after cooling the main engine of the diesel engine. With the development of explosion-proof rubber-tyred vehicle technology and the diversified needs of application fields, there must be a new cooling cycle system to meet the development needs of explosion-proof rubber-tyred vehicles. At present, the technical solutions commonly used in domestic explosion-proof diesel engine cooling circulati...
