　　一、沼气发电机组启动前检测

　　1、 Pre start inspection of biogas generator set

　　①检查沼气管路内沼气压力应介于3kPa-8kPa，甲烷含量应大于50%（体积），压力波动小于0.5kPa，沼气成分中硫的含量小于200mg/m3，无明显的臭鸡蛋味；无液态成分，湿度小于40%；（硫和水份过高，应更换脱硫脱水剂）；

　　① Check that the pressure of biogas in the biogas pipeline should be between 3kPa-8kPa, the methane content should be greater than 50% (volume), the pressure fluctuation should be less than 0.5kPa, the sulfur content in the biogas components should be less than 200mg/m3, and there should be no obvious rotten egg odor; No liquid components, humidity less than 40%; (If the sulfur and moisture are too high, the desulfurization and dehydration agent should be replaced);

　　②用肥皂水检查沼气管道各接头处无漏气现象；③检查机组接地线是否接地良好，负载线是否存在松动；

　　② Check for any air leaks at the joints of the biogas pipeline using soapy water; ③ Check whether the grounding wire of the unit is well grounded and whether the load line is loose;

　　④检查机油油位是否在标示刻度线以内，若不够请加同型号机油至标示线以内位置；

　　④ Check if the oil level is within the marked scale line. If it is not enough, please add the same type of oil to the position within the marked line;

　　⑤检查冷却液是否在水箱盖以下3cm左右，不足请加冷却液至上述位置；

　　⑤ Check if the coolant is about 3cm below the water tank cover. If it is insufficient, please add coolant to the above position;

　　⑥检查启动电瓶电压25-26V，液面应高出极板10-15mm（免维护电池除外）；（如果是12V电池供电，电瓶电压应为13-14V）；

　　⑥ Check the starting battery voltage of 25-26V, and the liquid level should be 10-15mm above the electrode plate (except for maintenance free batteries); If powered by a 12V battery, the battery voltage should be 13-14V;

　　⑦查传动皮带张力用手在皮带中部压下10-15mm为宜；

　　⑦ It is advisable to manually press down 10-15mm in the middle of the belt to check the tension of the transmission belt;

　　⑧检查发电机组负载开关位置，开关应处于关闭的状态的“OFF”位置（非常重要！）。
