Embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
Consult Fig. 1, shown in Figure 2; A kind of super-silent diesel generating set that the utility model provides; This unit adopt efficient sound absorbing material and with the noise reduction silencer of vanguard technology industrialized production to advance, ventilation channel and vent systems carried out noise reduction process, mainly comprises motor (10), generator (11), generator set controller (12) and noise reduction structure four major parts such as (13).
The noise reduction structure of unit (13) comprises the quiet cover of body (14), air intake passage (17), ventilation channel (20) and silencing apparatus four parts such as (21).The quiet cover employing of body stickup thickness is that the steel plate of the gum pad pasting acoustical cotton of 35mm is made, and the noise that has produced when having absorbed unit work efficiently intercepts noise and outwards propagates; The air intake guiding of the air mass flow that needs when venetian blind is worked unit gets into air intake noise reduction case, weakens equipment acoustic noise directly to external radiation; The casing that air intake noise reduction case (16) is made up of 6 anechoic sheets; Anechoic sheet (23) is divided into uniform air channel, 7 roads with air intake; Effectively the noise of absorption air flow generation and equipment acoustic noise are to external radiation, and anechoic sheet is the noise that produces when trapezoid shaped helps reducing air flow for two sections; A central diaphragm (22) is installed on the unit radiator, air intake and the air draft of unit separated, can stop the higher air draft backflow of temperature; Air draft noise reduction case by 7 be arranged in parallel, the anechoic sheet (24) that staggers each other in the position constitutes, and forms effective air draft space, help the diffusion of air draft and absorb the air draft noise; Netted air draft ventilated port is arranged on the quiet cover end face, helps the higher air draft of temperature and upwards discharges.Exhaust silencer is made up of the secondary composite muffler that impedance adds the sound-absorbing type; Dissipative muffler is in pipeline, to arrange sound-absorbing porous material; When air communication was crossed dissipative muffler, sound wave just caused air and the vibrations of fiber fines in the sound-absorbing material hole, because friction and viscous resistance; Acoustic energy becomes heat energy and absorbs, thereby plays the noise elimination effect; Reactive muffler is used to subdue narrow band noise and low, mid-frequency noise; Utilize difform pipeline and resonant cavity to carry out suitable combination; By means of pipeline section and shape variation and reflection and interference effect that the acoustic impedance that causes does not match and produced, reach the purpose of attenuate acoustic noise.
The unit intelligent controller adopts the ATmega64 chip to form control wiring, rotating speed, oil pressure, water temperature, DC electrical source voltage and the working time etc. of control motor.
The utility model unit has adopted advanced Optimal Structure Designing, environment friendly acoustical absorption material and multistage impedance to add active noise reduction such as sound-absorbing type composite muffler technology, and the noise of power 48kW unit is reduced to 60-65dB, has realized super-silent function.This technological scheme is equally applicable to 6 ~ 400kW unit.Unit has adopted intelligent controller, has realized that unit moves automatically, detects, controls, protection and functions such as long-haul telemetry, remote control and remote signalling.
Embodiment: following noise reduction technology with the super-silent diesel generating set of the super-silent diesel generator group profile of TC66 type.The basic building block of the quiet cover of body is that the gum pad pasting acoustical cotton that liner 35mm is thick (the following unit of 16KW is used 25mm) is made absorbent treatment on the thick steel plate of 2mm.Air intake passage is made up of air intake venetian blind and air intake noise reduction case, and the wind deflector length of venetian blind is 50mm, and incoming air area just guarantees that when design the gas handling system of motor and the cooling system of unit have enough fresh airs to suck; Wind deflector is " Z " font, and spacing is 50mm, and air intake wriggles through wind deflector and enters in the unit; Weaken equipment acoustic noise directly to external radiation; The noise reduction case is by 6 casings that anechoic sheet is formed that are arranged in parallel, and two ends are trapezoid shaped, lower resistance; Make air flow more smooth and easy, noise reduction is better.Ventilation channel is made up of row air intake noise reduction case and vent hole, air draft noise reduction case by 7 be arranged in parallel, casing that the anechoic sheet that staggers each other in the position is formed, the anechoic sheet two ends are trapezoidal; Adjacent two are staggered each other, form more spacious ventilation channel, make the air discharging more smooth and easy; Noise reduction is better; Vent hole is made up of the square hole of several 30mm * 30mm, is positioned at the end face of quiet cover, helps hot air and upwards discharges.Silencing apparatus adopts the secondary impedance to add sound-absorbing type composite muffler, and the one-level silencing apparatus is a dissipative muffler, around the pipeline that use sound-absorbing material filling exhaust is passed through; Secondary muffler is an impedance silencer, the silencing apparatus that uses reactive muffling unit and sound-absorbing material to constitute respectively; Composite muffler places within the quiet cover of body, has not only increased the noise elimination effect of silencing apparatus but also make that super-silent diesel generating set outward appearance is more attractive in appearance.
