        靜音發(fā)電機組在前期和后期的安裝

        返回 2024.06.06 來(lái)源:http://www.elmasticar.com 0

        靜音發(fā)電機組在前期生產(chǎn)后期的安裝中有很多需要注意的地方。靜音發(fā)電機組除具備系列柴油發(fā)電機組各項功能外,還具備以下特點(diǎn):機組噪音低,總體機構緊湊,占用空間??;箱體全部為可拆卸式結構,箱體采用鋼板拼接而成,表面涂有高性能防銹漆,同時(shí)具備降噪和防雨功能;箱體內部采用多層屏障阻抗錯配式消聲結構、內置式大型阻抗式消音器。箱體結構設計合理,箱體內部設有大容量油箱,左右同時(shí)設有兩扇檢修門(mén),以便機組故障檢修;同時(shí)在箱體上開(kāi)有觀(guān)察窗和機組緊急停機故障按鈕,以便觀(guān)察機組的運行情況及在機組出現緊急情況時(shí)以最快的速度停機避免機組受到損壞。今天我們談?wù)勳o音發(fā)電機組在消音器的選擇上,以及后期幾個(gè)系統設置要求。

        There are many things to pay attention to during the installation of silent generator sets in the early and later stages of production. The silent generator set not only has various functions of a series of diesel generator sets, but also has the following characteristics: low unit noise, compact overall structure, and small space occupation; The entire box body is a detachable structure, made of steel plates spliced together and coated with high-performance anti rust paint on the surface, while also having noise reduction and rain protection functions; The interior of the box adopts a multi-layer barrier impedance mismatch type noise reduction structure and a built-in large impedance type muffler. The box structure is designed reasonably, with a large capacity oil tank inside the box and two maintenance doors on both sides for easy maintenance of unit faults; At the same time, there is an observation window and an emergency stop button on the box to observe the operation of the unit and to stop the unit as quickly as possible in case of emergency to avoid damage to the unit. Today we will talk about the selection of silencers for silent generator sets and several system settings requirements in the later stage.

        1、噪音水平

        1. Noise level

        柴油發(fā)電機組產(chǎn)生的噪音應能有效地衰減,以滿(mǎn)足當地法規及安裝地的要求??赏ㄟ^(guò)正確地選擇消音器來(lái)實(shí)現:

        The noise generated by diesel generator sets should be effectively attenuated to meet local regulations and installation requirements. It can be achieved by selecting the muffler correctly:

        工業(yè)型:  可衰減12至18dBA

        Industrial type: can attenuate 12 to 18dBA

        住宅型:  可衰減18至25dBA

        Residential type: can attenuate 18 to 25dBA

        臨界型:  可衰減25至35dBA

        Critical type: can attenuate 25 to 35dBA

        2、排煙系統設置

        2. Smoke exhaust system settings

        盡可能降低排煙系統的背壓值。過(guò)高的背壓會(huì )負面影響燃燒效率,增加排氣溫度,從而導致發(fā)動(dòng)機功率損失,縮短其工作壽命。因此,應盡量縮短煙管長(cháng)度,減少彎頭個(gè)數,減少消音器阻力及增大煙管直徑。

        Try to reduce the back pressure value of the smoke exhaust system as much as possible. Excessive back pressure can negatively affect combustion efficiency, increase exhaust temperature, and lead to engine power loss, shortening its working life. Therefore, the length of the smoke pipe should be shortened as much as possible, the number of bends should be reduced, the resistance of the muffler should be reduced, and the diameter of the smoke pipe should be increased.

        3、排煙出口定位

        3. Smoke exhaust outlet positioning

        最方便的出口并非最佳的位置,設計師應綜合考慮風(fēng)向、建筑物設計、布局、距離及排煙流速等因素。應避免排煙進(jìn)入任何重要的鮮風(fēng)入口(窗、門(mén)、進(jìn)風(fēng)口、柴油發(fā)電機組燃燒新鮮空氣入口、柴油發(fā)電機組冷卻通風(fēng)入口等),防止新鮮空氣遭受排煙的污染;還應減少煙囪噪音對工人及鄰里的影響以及排煙中含帶的粉塵在相鄰建筑上的堆積。

        The most convenient exit is not the optimal location, and designers should consider factors such as wind direction, building design, layout, distance, and smoke exhaust flow rate comprehensively. Smoke exhaust should be avoided from entering any important fresh air inlet (windows, doors, air intakes, fresh air inlet for diesel generator set combustion, cooling and ventilation inlet for diesel generator set, etc.) to prevent fresh air from being contaminated by smoke exhaust; It is also necessary to reduce the impact of chimney noise on workers and neighbors, as well as the accumulation of dust contained in smoke exhaust on adjacent buildings.

        4、管路設計

        4. Pipeline design

        所有的排煙管路應得以良好支撐和固定。

        All smoke exhaust pipes should be well supported and fixed.

        無(wú)支撐的消音器不能安裝在柴油發(fā)電機組排煙歧管或柴油發(fā)電機組增壓器出口處。

        Unsupported silencers cannot be installed at the exhaust manifold or turbocharger outlet of diesel generator sets.

        煙管與柴油發(fā)電機組之間應安裝軟連接,以吸收管道的熱脹冷縮、機組的位移及振動(dòng),減少煙管對機組及煙管之間的重壓;軟連接應盡可能靠近機組排煙出口(增壓器或排氣歧管)。

        A soft connection should be installed between the smoke pipe and the diesel generator set to absorb the thermal expansion and contraction of the pipeline, the displacement and vibration of the unit, and reduce the heavy pressure of the smoke pipe on the unit and between the smoke pipes; The soft connection should be as close as possible to the exhaust outlet of the unit (turbocharger or exhaust manifold).

        排煙終端應安裝防雨帽、遮蓋物及其它防雨設計以防止雨雪進(jìn)入。接近機組的煙管部分應安裝有冷凝水收集器及排水閥。

        Smoke exhaust terminals should be equipped with rain caps, covers, and other rainproof designs to prevent rain and snow from entering. The smoke pipe near the unit should be equipped with a condensate collector and drainage valve.

        建議機組不與火爐、鍋爐或者其它設備共用排煙管道。運行中設備排放的炭塵、冷凝物的堆積會(huì )對非運行機組造成損害,被動(dòng)驅動(dòng)的增壓器因缺乏潤滑將導致軸承故障。

        It is recommended that the unit does not share smoke exhaust pipes with furnaces, boilers, or other equipment. The accumulation of carbon dust and condensate emitted by equipment during operation can cause damage to non operating units, and passive driven boosters may cause bearing failures due to lack of lubrication.

        5、長(cháng)度

        5. Length

        盡可能縮短排煙系統長(cháng)度,從而減少系統的阻力(背壓),更利于 煙氣排放;減少氣體冷凝機會(huì ),降低煙氣程度。

        Shorten the length of the smoke exhaust system as much as possible to reduce the resistance (back pressure) of the system, which is more conducive to smoke emission; Reduce the chance of gas condensation and reduce the degree of smoke.
