Special quiet speaker

Diesel generator sets with silent speakers are used for a great deal of their noise. In particular, hotels, high-end living areas, shopping malls and other places demanding environmental noise is an indispensable emergency equipment. For high-power units due to their own noise, only to achieve a larger amount of noise reduction to make the unit noise to meet the current environmental requirements. Silent generator sets can be placed indoors, can also be placed directly outside.
Product Details

Diesel generator sets / low-noise diesel generator sets comply with relevant national standards such as GB2820-90. Low-noise diesel generator sets include low-noise workstations, low-noise automatic generator sets, low-noise automotive power stations and low noise trailer power stations. Low-noise diesel generator set has the advantages of stable performance, reliable operation, low emission and low fuel consumption rate.fTp柴油发电机组租赁,发电机组租赁,东莞发电机出租,江苏发电机组租赁,浙江发电机组出租,静音型发电机组租赁,特种集装箱,定制

Unit noise reduction facilities
1, vibration damping facilities, diesel engines and generators and bridge between the use of high-performance shock absorbers to reduce vibration noise.
2, noise cover, using four to five layers of sound-absorbing material noise enclosures, technology is mature, sound-absorbing noise, the effect is obvious.
3, into the wind anechoic body, three layers of sound-absorbing material maze wind anechoic body, both to ensure adequate access to fresh air, but also effectively sealed the noise outside Yang.
4, exhaust muffler body, three layers of sound-absorbing material maze exhaust muffler body, both to ensure smooth ventilation, but also effectively sealed the spread of noise.
5, exhaust muffler, impedance composite muffler used, greatly reducing the emission of exhaust noise, emissions can meet the national standard.
6, the power cable connection using a fixed junction box structure, directly connected outside the box.
In addition, the structure of the acoustic enclosure door is similar to that of the acoustic enclosure. The window is double-glazed, and the doors and windows and the acoustic enclosure are tightly sealed to seal the noise to the maximum extent.
 
Features Description
1, Significant low noise performance, unit noise limit of 75dB (A) (1m away from the unit).
2, the overall design of the unit is compact, small size, novel and beautiful appearance.
3, multi-layer shield impedance mismatch noise enclosures.
4, efficient noise reduction multi-channel exhaust, into the exhaust passage, to ensure adequate power unit performance.
5, large-scale impedance muffler.
6, high-capacity fuel.
7, ad hoc fast open cover, easy maintenance.
structure:
Machine small size, light weight, compact structure. Soundproof hood handsome in appearance, disassembly is simple, easy to operate units. Supporting the brand-name diesel engines and brand generators and all solid seal automatic voltage regulator, excellent performance, reliable operation.
performance:
Noise (distance to unit 1M); ≤ 80db or 75db (sound pressure level); steady state voltage regulation: ≤ ± 1%, ≤ ± 0.5%; transient voltage regulation: ≤ + 20%, + 15% State frequency adjustment rate: ≤ 5%; Transient frequency adjustment rate: ≤ ± 10%; No-load voltage setting range: ≥ (95-105)% Un.
Technical Parameters:
Rated voltage: 400V; Rated speed: 1500r / min; Rated frequency: 50Hz; Rated power factor: 0.8 (lag).
Silent diesel generator sets, diesel generator sets is the introduction of foreign low-noise generators and engine technology and well-designed; advanced design concepts, the full range. In addition to a series of diesel generator sets, diesel generator sets of various functions, but also has the following characteristics: low noise unit, the overall body compact, small footprint; box all removable structure, the box made of steel splicing, Surface coated with high-performance anti-rust paint, both with noise and rain-proof function; box with multi-layer barrier impedance mismatch within the muffler structure, built-in large impedance muffler. Cabinet structure design is reasonable, the tank has a large capacity inside the tank, left and right at the same time with two access doors, in order to troubleshoot the unit; the same time in the box there is an observation window and the unit emergency stop fault button to observe the operation of the unit Situation and the unit in the event of an emergency to the fastest speed down to avoid damage to the unit
1. Noise standards in line with ISO374.
2. The interior uses a special silencer material, built-in silencer to make the structure compact. Good ventilation and radiation protection structure
3. Special handling of the box, fully adapted to all-weather use.
4. The rational position of the box set the observation window for easy observation and operation.
5. Special set of shock absorbers, the unit quiet and peaceful operation
6. High-capacity base fuel tank eliminates the need for installation and connection.
