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 t

Example Embodiment

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] figure 1 Shown is the overall structure diagram, the position and connection relationship of each part must be correct, and the installation should be firm.

[0018] The water-cooled radiator is equipped with a fan to dissipate heat. The water-cooled radiator is connected to the left and right water-cooled superchargers through the left and right exhaust manifolds. After the water is pressurized, it enters the water-air cooler, and the middle is connected by a pipeline to form a double cycle cooling inside and outside. It can act as a fire retardant.

[0019] All connecting pipes must be unblocked.

[0020] figure 2 Shown is the structure diagram of the exhaust manifold. There are two exhaust manifolds. The left and right exhaust manifolds have the same structure.

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...
