有时，沼气发动机组在不使用时会被搁置很长时间。错位时间长了，再启动就容易失灵。那么沼气发动机长期放置的注意事项如下：

Sometimes, biogas engine units are left unused for a long time. If the misalignment time is too long, it is easy to malfunction when restarted. So the precautions for long-term placement of biogas engines are as follows:

1.在进气口加入少量水机油，盘车使其附着在活塞顶部、气缸套内壁和气门密封面上，将气门设置在关闭状态，使气缸套与外界隔绝。

1. Add a small amount of engine oil to the intake port and rotate it to adhere to the top of the piston, the inner wall of the cylinder liner, and the valve sealing surface. Set the valve to the closed state to isolate the cylinder liner from the outside world.

2.当确定沼气发动机不会长时间使用时，要尽可能排干冷却水和润滑油。让沼气发电机组干净。

When it is determined that the biogas engine will not be used for a long time, it is necessary to drain the cooling water and lubricating oil as much as possible. Keep the biogas generator clean.

3.盖住空气滤清器、排气管和油箱，防止灰尘落入。

3. Cover the air filter, exhaust pipe, and fuel tank to prevent dust from falling in.

4.确保沼气发动机组清洁。去除表面的灰尘和油污。

4. Ensure the cleanliness of the biogas engine unit. Remove surface dust and oil stains.

5.取下沼气发动机的气门盖，用刷子涂上少量无水机油，刷在摇臂等部位。

5. Remove the valve cover of the biogas engine, apply a small amount of anhydrous engine oil with a brush, and brush it on the rocker arm and other parts.

6.沼气发动机应放置在通风良好、干燥和清洁的地方。严禁与化学品(如化肥、农药)一起存放。

6. Biogas engines should be placed in well ventilated, dry, and clean areas. It is strictly prohibited to store it together with chemicals such as fertilizers and pesticides.

下面沼气发电机组厂家总结在选购沼气发电机组时的几点建议：

Below are some suggestions from biogas generator manufacturers when purchasing biogas generators:

1.根据沼气产量，选择合适的装机容量，防止机械设备闲置或沼气浪费;

1. Select appropriate installed capacity based on biogas production to prevent idle mechanical equipment or biogas waste;

2.1000KW左右的沼气发生器市场占有率高，价格高，维护、检修、保养费用相对较低;

2. Biogas generators with a power of around 1000KW have a high market share, high prices, and relatively low maintenance, repair, and upkeep costs;

3.当采用多台发电机组时，宜采用1000KW左右的同一规格型号，以减少运行费用和备件储存。量少的时候选功率小一点的。如1000KW加1.500 kW，以便在气源变化较大时调节输出功率，保证发电机组在70%以上功率输出.

When multiple generator sets are used, it is advisable to use the same specification and model of around 1000KW to reduce operating costs and spare parts storage. When the quantity is small, choose one with lower power. Add 1.500 kW to 1000KW in order to adjust the output power when the gas source changes significantly, ensuring that the generator set outputs more than 70% of its power
