珀金斯發(fā)電機組對機房設(shè)計技術(shù)規(guī)范要求

一：機房地基

1.地基類型：

用于固定機組的底座 / 基座的地面 / 地基對于整個發(fā)電機機房設(shè)計是非常重要的，它必須滿足

A 承受機組凈重并經(jīng)受引擎運轉(zhuǎn)時的振動或重壓；

B 要足夠的堅硬且穩(wěn)定，這樣才不會因發(fā)生變形而對引擎和驅(qū)動裝置的定位造成影響；

C 吸收來自運行組件的振動，且能預(yù)防其傳遞給周圍地板及墻壁等。

2.底土選擇

A 機房底土必須有足夠的承載強度以支撐成套機組加上機組立于其上的混凝土基礎(chǔ)重量；若對底土的承載強度不明，應(yīng)向合格的土木工程師征求意見，以確定混凝土的類型和尺寸；

B 我們提議使用固定的混凝土砌塊，并推薦其平面尺寸是在機組的周 邊有 300 -450mm 的余量；

C 砌塊的表面層高度在 100 -230mm 之間，且形成一個方形底座。

3.混凝土地基

A 砌塊深度的計算方法：

D= 混凝土砌塊深度 單位： M

W= 發(fā)電機總重量 單位： kg

d= 混凝土密度 單位： kg/m ³

（如果此精確值未知， d= 2403.8kg /m ³）

B= 混凝土的寬度 單位： M

L= 混凝土的長度 單位： M

B 混凝土地基

4．多機并機機房中，每臺發(fā)電機必須擁有自己獨立的基座

二．機房布置

１.應(yīng)方便日常護養(yǎng)

２. 機房安裝指導(dǎo)

　　燃油管和接頭避免使用塑料和其它不當(dāng)?shù)牟牧希驗檫@些材料可能會腐蝕，或者破損，造成燃料泄漏燃油管路應(yīng)遠離高溫排氣管排氣系統(tǒng)絕熱，采用絕熱防護罩或絕熱材料包裹 注意：干式的排氣岐管不能用絕熱材料包裹 在機房內(nèi)安裝滅火系統(tǒng)考慮由底殼機油排放措施，在底部準(zhǔn)備積污槽檢查入口是否足夠大，以允許引擎 / 交流發(fā)電機移出提供充足的照明和電源插座屋頂起重橫梁以便維修保養(yǎng)考慮引擎冷卻液排放措施為安全起見，所有旋轉(zhuǎn)軸都要采取相應(yīng)的防護措施。

３. 典型的機房布置應(yīng)具有來自散熱器的熱風(fēng)用導(dǎo)風(fēng)管道排至機房外并且避免回流 排氣系統(tǒng)從屋頂進行支撐，安裝彈性波紋管來隔離引擎和排氣系統(tǒng)熱風(fēng)導(dǎo)出管道，燃油管路和電氣相對引擎和交流發(fā)電機的連接，留有一點的余量日用油箱通過機房外遠置安裝的油庫供應(yīng)在發(fā)動機沒有運行期間，啟動電池必須使用充電器充滿，該充電器可以集成在控制柜內(nèi)。

三．機房通風(fēng)

1．通風(fēng)
　　基本原則是將室內(nèi)熱空氣排出并在盡可能減小回流的情況下導(dǎo)入外面環(huán)境溫度下的空氣目標(biāo)是得到盡可能低的的冷空氣，使它吹過散熱器并排至室外散熱器熱風(fēng)必須通過管道引至通風(fēng)處僅僅將散熱器安裝在接近墻上的開口處，不是合適的安裝。

２.出口 / 入口尺寸

排風(fēng)口應(yīng)該通風(fēng)順暢，并且應(yīng)該比散熱器面積大大約 25%散熱器排風(fēng)管道必須有一段柔性的部分，以隔離振動和運動。對于機組整體安裝在減震器上的懸置方式，這一點尤其重要。進風(fēng)口也應(yīng)該通風(fēng)順暢，并且應(yīng)該比散熱器面積大大約 25%。

Perkins generator set technical specifications for room design
A: room foundation
1 Foundation type:
For fixing the base unit / base floor / foundation for the entire generator room design is very important, it must meet
A unit weight and subjected to withstand vibration or pressure when the engine is running;
B to be sufficiently hard and stable, so that it will not deform and affect the positioning engine and drive unit;
C absorbs vibrations from running components, and can prevent its transmission to the surrounding floor and walls, etc..
2 subsoil choice.
A room subsoil must have sufficient strength to support the complete unit load plus the weight of the unit to stand on the concrete foundation; If the bearing strength of the subsoil is unknown, should consult a qualified civil engineer, to determine the type and size of the concrete;
B We propose the use of a fixed concrete block, and its plane size is recommended in the surrounding units have 300-450mm of headroom;
C block height between the surface layer of 100-230mm, and forming a square base.
3. Concrete foundation
A block depth calculation:
D = depth of concrete masonry units: M
W = the total weight of the generator unit: kg
d = concrete density units: kg / m ³
(If the exact value is unknown, d = 2403.8kg / m ³)
Unit B = width of concrete: M
Unit of length L = concrete: M
B concrete foundation
4. Multi-machine and machine room, and each generator must have its own independent base
Two. Room layout
1 should facilitate daily nursing
2 room installation instructions
Fuel pipe and fittings to avoid improper use of plastics and other materials, because these materials may corrode or damage, resulting in a fuel leak fuel line should stay away from high temperature exhaust pipe exhaust system insulation, the use of insulation or insulation material wrapped shield Note: Dry exhaust manifold extinguishing system can not be installed emission measures considered by the oil pan at the bottom of the tank to check the entrance to prepare the contamination in the engine room is large enough to wrap insulating material to allow the engine / alternator out of the provision of adequate lighting Lifting the roof beams and electrical outlets to consider the engine coolant maintenance emission measures for safety reasons, all axes of rotation should take appropriate protective measures.
3 should have a typical room layout from the evaporator with hot air guide duct and discharged to outside the room to avoid reflux for supporting the exhaust system from the roof, flexible bellows mounted engine and exhaust system to isolate hot export pipeline, fuel line and electrical engines and alternators relative connection, leaving little margin for daily use by tank outside the room away home depot supply installed during engine is not running, start the battery charger must be filled, the charger can be integrated in the control cabinet.
Three. Engine room ventilation
1. Ventilation
The basic principle is to heat the room air is discharged outside the target, and air was introduced at ambient temperature as in the case of reflux is reduced as low as possible to get the cold air to the outdoor side heat sink so that it blows the hot air must pass through the radiator ventilation pipes lead to the radiator just installed close to the wall opening is not suitable installation.
2 outlet / inlet size
Ventilation vents should be smooth and should be more than about 25% of the area is large radiator radiator exhaust pipe there must be a flexible section to isolate vibration and movement. Mounting method for the whole unit is mounted on the shock absorber, which is particularly important. Ventilation inlets should be smooth and should be more than about 25% of the large radiator area.
