Abstract

The invention relates to a cooling device for an explosion-proof diesel engine. The cooling device mainly comprises a water cooling radiator, a water-air intercooler, a flame arrestor, left and right water cooling pressurizers, left and right water cooling exhaust manifolds, internal and external circulating water pumps, left and right exhaust seats, an air inlet pipe, an air outlet pipe, an air exhaust pipe, a water inlet pipe, a water outlet pipe, a water release pipe and a three-way valve, wherein the water cooling radiator and the water-air intercooler are adopted for realizing double cooling, the flame arrestor is used for resisting fire, the double water cooling pressurizers are used for pressurization and the internal and external circulating water pumps are used for water feeding;and a fan is arranged in the water cooling radiator for dissipating heat so that a high-power diesel engine can be well cooled during high-speed running, thereby guaranteeing the safety of running. The device has the advantages of reasonable and advanced design, compact, safe, stable and reliable structure, good use effect and fewer faults, is the ideal cooling device for the high-power diesel engine and can also be used on similar engines.

Description

technical field [0001] The invention relates to a cooling device for an explosion-proof diesel engine, which belongs to the technical field of design and manufacture of explosion-proof diesel engine components. Background technique [0002] A large number of diesel engines are used in coal mines. Because they work in the harsh environment of underground mines, explosion-proof designs for diesel engines are required. [0003] During the operation of a diesel engine, the temperature will gradually rise during diesel combustion and air-assisted combustion, especially the combustion temperature of a high-power diesel engine is 1500 ° C, and the surface temperature can reach 150 ° C, which brings great pressure to the operation of the diesel engine. Potential safety hazards will also damage the parts, promote the aging of the parts, and even cause spontaneous combustion and safety accidents, hindering the normal operation of the diesel engine. [0004] At present, the cooling of...

Problems solved by technology

[0003] During the operation of a diesel engine, the temperature will gradually rise during diesel combustion and air-assisted combustion, especially the combustion temperature of a high-power diesel engine is 1500 ° C, and the surface temperature can reach 150 ° C, which brings great pressure to the operation of the diesel engine. Potential safety hazards can also damage the parts, promote the aging of the parts, and even cause spontaneous combustion and safety accidents, hindering the normal operation of the diesel engine

[0004] At present, the cooling of high-power diesel engines has great disadvantages, and they are not ideal. Especially for high-power engines operating in harsh environments, temperature control has become a major problem.
