沼气发动机是一种很便捷的自发电装置，该设备在不用的时候会长时间的放置。在长时间错误的放置后，再次启动就容易出现故障。那么沼气发电机组停机及长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?

沼气发电机组停机

Shutdown of biogas generator set

卸载：在关闭沼气发电机组之前，先卸载负载。

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

怠速运转：以额定转速运转几分钟，初冷后，将怠速/额定切换开关置于“怠速”位置，使机组怠速运转，降低水温和油温。

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.

切断气源：当机组“水温”、“油温”降至60℃以下时，关闭手动气阀。剩余的气体可使设备运行1或2分钟。用完气体后，机组自动停机。

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.

关机后，关闭控制屏面板上的按键。

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

除工作场所发生飞车或可燃气体等不可预见的事故外，在正常情况下严禁带载停机。

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.

停机后如需长期存放，应将沼气发电机组的冷却水和油放掉，清洗机组表面，并在相关部位涂上密封油，以防零件生锈。

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.

紧急停机。发电机组正常运行，不按正常停机步骤停机，即为紧急停机。主要有两种情况：（1）发电机组因超速、低油压等故障会报警并自行停机。(2)在运行过程中，当遇到危及人员和设备安全的紧急情况时，发电机操作人员按“急停”按钮，手动使机组停机。

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.

紧急停机处理措施：切断电源，用车刀手动转动曲轴，同时用手动油泵抽油。机组水温、油温降至60℃以下后，停止检查和处置。

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.

沼气发电机组长期放置

Long term placement of biogas generator set

在进气口加入少量水和油，摇动汽车使其粘附在活塞顶部、缸套内壁和气门密封面上，并将气门置于关闭状态以分离缸套来自外界。

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.

当确定沼气机长期不用时，应尽量放掉冷却水和润滑油。保持沼气发电机组清洁。

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.

盖好空气滤清器、排气管和油箱，防止灰尘落入。

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

必须保证沼气机组的清洁。清除表面的灰尘和油污。

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

拆下沼气发动机的气门盖，用刷子蘸取少量无水油，刷在摇臂上，直至接触到零件。

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.

沼气发电机组应放置在通风良好、干燥、清洁的地方。严禁与化学品（如化肥、农药等）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.).
