柴油發電機組是往復式運轉機械，運行是將產生較大的震動。因此，基礎是安裝中主要的部分，其作用是：

Diesel generator sets are reciprocating machinery that will generate significant vibrations during operation. Therefore, the foundation is the main part of installation, and its role is to:

支撐柴油發電機組及其他輔助部件的重量；

Support the weight of the diesel generator set and other auxiliary components;

吸收機組在運行中產生的不平衡力，保持發動機、發電機和隨機輔助設備之間的安裝距離；

Absorb the unbalanced forces generated by the unit during operation, maintain the installation distance between the engine, generator, and random auxiliary equipment;

將機組的震動和周圍結構隔離，以減少機組振動對機房和附近建筑物造成的影響。

Isolate the vibration of the unit from the surrounding structure to reduce the impact of unit vibration on the computer room and nearby buildings.

一、機組安裝對基礎的要求

1、 Requirements for foundation during unit installation

支承整臺機組的重量和機組運行時不平衡力所產生的動態沖擊負載；

Support the weight of the entire unit and the dynamic impact load generated by unbalanced forces during unit operation;

具有足夠的剛度和穩定度，以防止變形而影響柴油發動機和主交流發電機及附件等的同軸度；

Having sufficient stiffness and stability to prevent deformation from affecting the coaxiality of the diesel engine, main AC generator, and accessories;

基礎不能和其它建筑物的地基相連；

The foundation cannot be connected to the foundation of other buildings;

基礎的寬度及深度應滿足要求；

The width and depth of the foundation should meet the requirements;

保證基礎的水平度及一定的光滑度；

Ensure the level and smoothness of the foundation;

有條件的的用戶可預留排污槽，以便廢水、污油等及時流走；預留發電機配電輸出電纜溝。

Conditional users can reserve sewage tanks to facilitate the timely flow of wastewater, dirty oil, etc; Reserve cable trenches for generator distribution output.

通常，混凝土安裝基礎是一種可靠簡便的安裝方式，建議用戶優先采用。當澆筑混凝土底座時，應確保混凝土的表面平整、沒有任何損傷，建議用戶結合使用水平儀或類似儀器進行機組及其排氣系統的安裝。

Usually, concrete installation foundation is a reliable and convenient installation method, and it is recommended that users prioritize it. When pouring concrete bases, it is necessary to ensure that the surface of the concrete is flat and free from any damage. It is recommended that users use a spirit level or similar instrument for the installation of the unit and its exhaust system.

二、減振基礎

2、 Vibration reduction foundation

如發電機組已裝備有內置或外置減振裝置（康爾信機組均已具備），同時樓板及周圍的支撐結構的承重強度能承受（機組總重的1.8 倍+混凝土底墊的重量），機組可不再做減振基座。

If the generator set is already equipped with built-in or external vibration damping devices (which are already available in Kongxin units), and the load-bearing strength of the floor slab and surrounding support structures can withstand (1.8 times the total weight of the unit+the weight of the concrete foundation pad), the unit can no longer be used as a vibration damping base.

三、基礎的常見做法

3、 Common basic practices

將設備基礎范圍內底板鑿毛，其四周底板面鑿去混凝土保護層，露出的鋼筋與設備基礎鋼筋焊接，高度為150～200mm；

Chisel the bottom plate within the scope of the equipment foundation, remove the concrete protective layer from the surrounding bottom plate surface, and weld the exposed steel bars with the equipment foundation steel bars, with a height of 150-200mm;

地基周圍沒邊比機組地盤每邊各長出150～300mm；

There is no edge around the foundation that is 150-300mm longer than each side of the unit site;

地基厚度由上面基礎原公式確定，如果使用的地腳螺釘深度取H=0.05m；

The thickness of the foundation is determined by the original formula above, and if the depth of the foundation screw used is H=0.05m;

地基底部與機房地面間留200mm的槽，槽內以充滿部分瀝青混凝土密封形成減震層；

A 200mm groove should be left between the bottom of the foundation and the ground of the computer room, and the groove should be filled with asphalt concrete to form a shock absorber layer;

地基表面應進行防水，防油處理，基坑地面應夯實；

The surface of the foundation should be treated with waterproofing and oil resistance, and the ground of the foundation pit should be compacted;

機組的地腳螺栓可以一次性澆筑，也可以預留孔進行二次澆筑，螺釘位置尺寸應根據生產廠商提供的準確尺寸確定。

The anchor bolts of the unit can be poured in one go or reserved holes for secondary pouring. The position and size of the screws should be determined based on the accurate size provided by the manufacturer.
