Description
Technical field
The present invention relates to a kind of mute diesel generator 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.
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 generator 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.
Diesel generating set can produce the noise of 95～110db usually when operation, if do not take necessary noise reduction measure, the noise of unit operation will cause serious harm to surrounding environment.Diesel generating set is the complex machines of multiple sound source, different along with set structure pattern and size, running operating mode, each sound generation source is different to the influence of overall noise, generally speaking, each noise like of unit is roughly arranged in the following order: exhaust sound, combustion noise or mechanical noise, fan noise, induction noise.Wherein exhaust sound is the major component of engine air aerodynamic noise, and its noise is generally wanted the high 10～15db of ratio engine complete machine, is the part that at first needs to carry out noise reduction control.Therefore in order to protect and to improve environmental quality, must control noise.
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 mute diesel generator set, it has two intake grills and an exhaust outlet forms two air-guiding aisles, when air communication is crossed air-guiding aisle, sound wave reaches the quiet purpose of eliminating the noise because friction and viscous resistance become heat energy.
The present invention can be implemented by the following technical programs:
A kind of mute diesel generator set, comprise frame, diesel engine and with the generator of the coaxial setting of bent axle of described diesel engine, offer first intake grill, second intake grill, exhaust outlet on the described frame, be provided with ventilation case, wind-guiding case, wind scooper, guard shield induced draft plate in the described frame, described first intake grill, ventilation case, wind-guiding case, exhaust outlet form first air-guiding aisle successively, and described second intake grill, wind scooper, guard shield induced draft plate, wind-guiding case, exhaust outlet form second air-guiding aisle successively.
Described frame comprises metallic case and the noise reduction cotton that is arranged on the described metallic case inwall.
Also be provided with damping device in the described frame, described damping device is made up of vibration damper plate and the rubber pad that is fixedly installed on the vibration damper plate.
Described bent axle one end is provided with the flywheel with fan blade, and described flywheel is between the wind scooper and guard shield induced draft plate of second air-guiding aisle.
Compared with the prior art the present invention has following advantage:
The present invention is directed to the major component of noise in the diesel generating set, promptly at first consider the control exhaust sound, on frame, offer first intake grill, second intake grill, exhaust outlet, form two intake grills and two air-guiding aisles of an exhaust outlet formation in the frame, when air communication is crossed air-guiding aisle, sound wave is because friction and viscous resistance become heat energy, thereby controlling noise reaches the quiet purpose of eliminating the noise.Compared with prior art, the noise when greatly reducing unit operation has reduced the influence that surrounding environment is caused.
