The beneficial effects of the utility model:
The set air-air intercooler of the utility model is in order to the fresh air of cooling supercharging (after testing air temperature can be reduced to 50 ℃ following), increased inlet air density, for automatically controlled anti-explosion diesel engine firing chamber provides more air, make burning more fully thoroughly.Not only improved the power of diesel engine for this reason, and realized discharge clean, reached the good result of energy-saving and emission-reduction.Also further optimize the performance of existing automatically controlled anti-explosion diesel engine, be more conducive to operation application under ore deposit.
Accompanying drawing explanation
Accompanying drawing 1 is the automatically controlled anti-explosion diesel engine structural representation of the absolutely empty middle cold type of the utility model;
Accompanying drawing 2 is the structural representation of the utility model assembly air-air intercooler;
Accompanying drawing 3 is the structural representation of water-cooled exhaust-gas turbocharger described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are further described:
As shown in Figure 1,
The utility model comprises diesel engine body 1 and automatical control system thereof, also comprises the assemblies such as air-air intercooler 2 and cooling water tank 3 thereof, water-cooled exhaust-gas turbocharger 4, air-strainer 5, emission-control equipment 6, air inlet bellows 7, exhaust expansion bellows 8, air inflow anti-explosion fence 9, exhaust explosion fence 10.In figure, also mark to install the utility model automatical control system flame-proof type control box 11 and in order to install automatical control system power supply system at flame-proof type power pack 12.As seen from the figure, the waste gas that the discharge manifold of diesel engine body is discharged enters water-cooled exhaust-gas turbocharger, under the promotion of waste gas inertia impulsive force, the turbine compression of the other end, the fresh air sucking from air-strainer 5, and enter air-air intercooler 2 through air inlet bellows 7, in view of air-air intercooler 2 and cooling water tank 3 effects, air cooling-down in air-air intercooler 2, density and pressure increase, through air inflow anti-explosion fence 9, enter engine combustion indoor, owing to obtaining sufficient air, make burning more abundant, improved the power of diesel engine.And the waste gas that enters water-cooled exhaust-gas turbocharger is after exhaust expansion bellows 8, waste gas treatment tank 6 purified treatment, be disposed in atmosphere through exhaust explosion fence 10 in the mode of steam.
