Abstract
A kind of diesel generating set, comprise diesel engine and with the generator of the coaxial setting of bent axle of described diesel engine, described bent axle is provided with the flywheel with fan blade, described flywheel outer installment has the wind scooper with intake grill and exhaust outlet.Because the bent axle of the present invention's diesel engine is provided with the flywheel that is used to cool off diesel engine, the rotation of bent axle drives flywheel and rotates, make air outside enter after flywheel forms cooling air by the intake grill of wind scooper, cooling air is blown out by the exhaust outlet of wind scooper again, carry out air-cooled to diesel engine, the heat that diesel generating set produces is discharged outside the unit casing, reached the purpose of lasting wind cooling temperature lowering.
Description
Technical field
The present invention relates to a kind of diesel generating set, relate in particular to a kind of air-cooling device of diesel generating set.
Background technique
Diesel generating set is a kind of small power generation equipment, and it is to be that fuel is the dynamic power machine that prime mover drives generator for electricity generation with the diesel engine with diesel oil etc.A whole set of unit generally is made up of with parts such as storage battery, protective gear, emergent cabinets diesel engine, generator, control box, fuel tank, starting and control.Integral body can be fixed on location use on the pedestal, also can be contained on the trailer and use for moving.Diesel generating set is because its volume is little, flexible, light, comprehensive, be convenient to operation and maintenance, so be widely used in departments such as mine, railway, open-air building site, road traffic maintenance and factory, enterprise, hospital, as standby power supply or interim power supply.
The working principle of diesel generating set is the Diesel Driven generator operation, is electric energy with the Conversion of energy of diesel oil.In diesel engine cylinder, fully mix with the high-pressure atomization diesel oil that oil nozzle ejects through the clean air after the air-strainer filtration, extruding lower volume at piston stroking upward is dwindled, temperature raises rapidly and reaches the burning-point of diesel oil, diesel oil is lighted, and mixed gas acutely burns, and volume expands rapidly, promote descent of piston, be called " acting ".Each cylinder is acting successively in certain sequence, and the thrust that acts on the piston has become the strength that promotes the bent axle rotation through connecting rod, thereby drives crankshaft rotating.
With the coaxial installation of brushless synchronous alternator and crankshaft of diesel engine, just can utilize the rotation of diesel engine to drive the rotor of generator, utilize " electromagnetic induction " principle, generator will be exported induction electromotive force, just can produce electric current through the load circuit of closure.
Yet because the diesel generating set of prior art does not have flywheel and with the lead wind scooper of casing outside of cooling air, temperature is higher when causing diesel generating set in working order, has directly influenced the proper functioning of diesel generating set and the normal output of rated power.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide a kind of diesel generating set, flywheel on it can carry out wind-force cooling to diesel engine, the outside of the cooling air guiding casing that wind scooper can form flywheel, and temperature is higher when having prevented that diesel generating set is in working order.
The present invention can be implemented by the following technical programs:
A kind of diesel generating set, comprise diesel engine and with the generator of the coaxial setting of bent axle of described diesel engine, described bent axle is provided with the flywheel with fan blade, described flywheel outer installment has the wind scooper with intake grill and exhaust outlet.
The exhaust outlet of described wind scooper is connected with blower cover.
The exhaust outlet of described wind scooper is positioned at the top of described flywheel.
Described wind scooper is positioned at a sidepiece of diesel generating set.
Compared with the prior art the present invention has following advantage: the bent axle of the present invention's diesel engine is provided with the flywheel that is used to cool off diesel engine, the rotation of bent axle drives flywheel and rotates, make air outside enter after flywheel forms cooling air by the intake grill of wind scooper, cooling air is blown out by the exhaust outlet of wind scooper again, carry out air-cooled to diesel engine, the heat that diesel generating set produces is discharged outside the unit casing, reached the purpose of lasting wind cooling temperature lowering.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Wherein:
1, diesel engine; 11, bent axle; 2, flywheel; 3, wind scooper; 31, intake grill; 32, exhaust outlet; 4, blower cover.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the invention are elaborated:
As shown in Figure 1, a kind of diesel generating set, comprise diesel engine 1 and with the generator of the bent axle 11 coaxial settings of described diesel engine 1, described bent axle 11 is provided with the flywheel 2 with fan blade, described flywheel 2 outer installment have the wind scooper 3 with intake grill 31 and exhaust outlet 32.
Because the bent axle 11 of the present invention's diesel engine 1 is provided with the flywheel 2 that is used to cool off diesel engine, the rotation of bent axle 11 drives flywheel 2 and rotates, make air outside enter after flywheel 2 forms cooling air by the intake grill 31 of wind scooper 3, cooling air is blown out by the exhaust outlet 32 of wind scooper 3 again, carry out air-cooled to diesel engine 1, the heat that diesel generating set produces is discharged outside the unit casing, reached the purpose of lasting wind cooling temperature lowering.
The exhaust outlet 32 of described wind scooper 3 is connected with blower cover 4, and blower cover 4 is guided cooling air into diesel engine.
The exhaust outlet 32 of described wind scooper 3 is positioned at the top of described flywheel 2.
Described wind scooper 3 is positioned at a sidepiece of diesel generating set.
The foregoing description only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this art can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
