沼氣發動機是一種很便捷的自發電裝置，該設備在不用的時候會長時間的放置。在長時間錯誤的放置后，再次啟動就容易出現故障。那么沼氣發電機組停機及長期放置要做的事情是哪些呢？

Biogas engine is a very convenient self generating device, which can be placed for a long time when not in use. After a long time of wrong placement, it is easy to fail when it is started again. So what are the things to do when the biogas generator unit is shut down and placed for a long time?

沼氣發電機組停機

Shutdown of biogas generator set

卸載：在關閉沼氣發電機組之前，先卸載負載。

Unloading: unload the load before shutting down the biogas generator set.

怠速運轉：以額定轉速運轉幾分鐘，初冷后，將怠速/額定切換開關置于“怠速”位置，使機組怠速運轉，降低水溫和油溫。

Idle operation: operate at the rated speed for several minutes. After initial cooling, place the idle / rated switch in the "idle" position to make the unit idle and reduce the water and oil temperature.

切斷氣源：當機組“水溫”、“油溫”降至60℃以下時，關閉手動氣閥。剩余的氣體可使設備運行1或2分鐘。用完氣體后，機組自動停機。

Cut off the air source: when the "water temperature" and "oil temperature" of the unit fall below 60 ℃, close the manual air valve. The remaining gas can run the equipment for 1 or 2 minutes. After using up the gas, the unit will shut down automatically.

關機后，關閉控制屏面板上的按鍵。

After shutdown, turn off the key on the control panel.

除工作場所發生飛車或可燃氣體等不可預見的事故外，在正常情況下嚴禁帶載停機。

Except for unforeseen accidents such as flying car or combustible gas in the workplace, it is strictly prohibited to stop with load under normal circumstances.

停機后如需長期存放，應將沼氣發電機組的冷卻水和油放掉，清洗機組表面，并在相關部位涂上密封油，以防零件生銹。

If it needs to be stored for a long time after shutdown, drain the cooling water and oil of the biogas generator set, clean the surface of the unit, and apply sealing oil on relevant parts to prevent parts from rusting.

緊急停機。發電機組正常運行，不按正常停機步驟停機，即為緊急停機。主要有兩種情況：（1）發電機組因超速、低油壓等故障會報警并自行停機。(2)在運行過程中，當遇到危及人員和設備安全的緊急情況時，發電機操作人員按“急停”按鈕，手動使機組停機。

Emergency stop. If the generator set operates normally and does not stop according to the normal shutdown steps, it is an emergency shutdown. There are two main situations: (1) the generator set will alarm and shut down automatically due to overspeed, low oil pressure and other faults. (2) During operation, in case of emergency endangering the safety of personnel and equipment, the generator operator shall press the "emergency stop" button to manually shut down the unit.

緊急停機處理措施：切斷電源，用車刀手動轉動曲軸，同時用手動油泵抽油。機組水溫、油溫降至60℃以下后，停止檢查和處置。

Emergency shutdown measures: cut off the power supply, manually rotate the crankshaft with turning tool, and pump oil with manual oil pump at the same time. After the water temperature and oil temperature of the unit drop below 60 ℃, stop inspection and disposal.

沼氣發電機組長期放置

Long term placement of biogas generator set

在進氣口加入少量水和油，搖動汽車使其粘附在活塞頂部、缸套內壁和氣門密封面上，并將氣門置于關閉狀態以分離缸套來自外界。

Add a small amount of water and oil into the air inlet, shake the car to make it adhere to the top of the piston, the inner wall of the cylinder liner and the valve sealing surface, and put the valve in the closed state to separate the cylinder liner from the outside.

當確定沼氣機長期不用時，應盡量放掉冷卻水和潤滑油。保持沼氣發電機組清潔。

When it is determined that the biogas machine is not used for a long time, the cooling water and lubricating oil shall be drained as far as possible. Keep the biogas generator set clean.

蓋好空氣濾清器、排氣管和油箱，防止灰塵落入。

Cover the air filter, exhaust pipe and oil tank to prevent dust from falling.

必須保證沼氣機組的清潔。清除表面的灰塵和油污。

The cleaning of biogas unit must be ensured. Remove dust and oil on the surface.

拆下沼氣發動機的氣門蓋，用刷子蘸取少量無水油，刷在搖臂上，直至接觸到零件。

Remove the valve cover of biogas engine, dip a small amount of anhydrous oil with a brush and brush it on the rocker arm until it contacts the parts.

沼氣發電機組應放置在通風良好、干燥、清潔的地方。嚴禁與化學品（如化肥、農藥等）一起存放。

The biogas generator set shall be placed in a well ventilated, dry and clean place. It is strictly prohibited to store with chemicals (such as chemical fertilizers, pesticides, etc.).
