When the diesel generator is running, it will generally be fixed at a position before running. If it is not fixed well, the vibration phenomenon during the movement will bring trouble to the operation of the diesel generator, and even cause the diesel generator to stop running in case of failure.

1、安裝地點需通風良好，發電機端應有足夠的進風口，柴油機端應有良好的出風口。出風口面積應大于水箱面積1.5倍以上。

1. The installation site shall be well ventilated. There shall be sufficient air inlet at the generator end and good air outlet at the diesel engine end. The air outlet area shall be more than 1.5 times larger than the water tank area.

2、安裝地的周圍應保持清潔，避免在附近放置能產生酸性、堿性等腐蝕性氣體和蒸汽的物品。有條件的應配置滅火裝置。

2. The surroundings of the installation site shall be kept clean and articles that can produce acidic, alkaline and other corrosive gases and vapors shall not be placed nearby. If possible, fire extinguishing devices shall be equipped.

3、在室內使用，必須將排煙管道通導室外，管徑必須≥消音器的出煙管直徑，所接之管路的彎頭不宜超過3個，以保證排煙暢通，并應將管子向下傾斜5-10度，避免雨水注入；若排氣管時垂直向上安裝的，則必須加裝防雨罩。

3. For indoor use, the smoke exhaust pipe must be connected to the outside, the pipe diameter must be ≥ the diameter of the smoke outlet pipe of the silencer, and the elbows of the connected pipeline should not exceed 3 to ensure smooth smoke exhaust, and the pipe should be inclined downward by 5-10 degrees to avoid rainwater injection; If the exhaust pipe is installed vertically upward, a rain cover must be installed.

4、基礎采用混凝土時，在安裝時須用水平尺測其水平度，使機組固定于水平的基礎上。機組與基礎之間應有專用防震墊或用底腳螺栓。

4. When the foundation adopts concrete, the levelness must be measured with a level ruler during installation to fix the unit on a horizontal foundation. Special shockproof pads or foot bolts shall be provided between the unit and the foundation.

5、機組外殼必須有可靠的保護接地，對需要有中性點直接接地的發電機，則必須由人員進行中性接地，并配置防雷裝置，嚴禁利用市電的接地裝置進行中性點直接接地。

5. The unit shell must have reliable protective grounding. For generators that need neutral point direct grounding, professionals must conduct neutral grounding and configure lightning protection devices. It is strictly prohibited to use the grounding device of municipal power for neutral point direct grounding.

6、發電機與市電的雙向開關必須分開。

6. The two-way switch between the generator and the mains must be separated.

柴油發電機為什么隔一段時間就要保養呢？因柴油發電機組長期處于靜態，機組本身各種材料會與機油、冷卻水、柴油、空氣等發生復雜的化學、物理變化，可能導致機組出現如下故障。

Why should diesel generators be maintained at intervals? Due to the long-term static state of the diesel generator set, various materials of the unit will undergo complex chemical and physical changes with engine oil, cooling water, diesel, air, etc., which may lead to the following faults of the unit.

1、水進入柴油機，由于空氣中水氣在溫度的變化發生冷凝現象，結成水珠掛附在油箱內壁，流入柴油，致使柴油含水量超標，這樣的柴油進入發動機高壓油泵，會銹蝕精密耦合件柱塞，嚴重的會損壞機組，定期維護即有效可避免。

1. When water enters the diesel engine, the water vapor in the air condenses due to the change of temperature, forms water droplets, hangs on the inner wall of the oil tank and flows into the diesel, resulting in the water content of the diesel exceeding the standard. When such diesel enters the engine high-pressure oil pump, it will rust the plunger of the precision coupling and seriously damage the unit. Regular maintenance can be effectively avoided.

2、機油變質，機油的保持期（二年）發動機的機油是機械潤滑作用，而機油也有一定的保持期，長時間存放，機油的物理化學性能會發生變化，造成機組工作時潤滑狀況惡化，容易引發機組零件損壞，所以潤滑油要定期更換。

2. The engine oil deteriorates and the retention period of the engine oil (two years) the engine oil is mechanical lubrication, and the engine oil also has a certain retention period. If it is stored for a long time, the physical and chemical properties of the engine oil will change, resulting in the deterioration of the lubrication condition of the unit during operation, which is easy to cause the damage of unit parts, so the lubricating oil should be replaced regularly.
