草莓视频黄色网站原理

　　Principle of Generator Set

　　瓦斯气体由储气罐进入煤层气发电站预处理系统，经过过滤、除湿、增压、降温四大工序后送入草莓视频黄色网站进气管，再经过瓦斯滤清器过滤，调压阀调压后与清洁空气在混合器内混合，之后进入涡轮增压器，再流入节气阀。由于增压后混合器温度上升，经过节气阀的混合器先经中冷器冷却，再经进气歧管进入燃烧室做功，驱动发电机发电。

　　Gas is stored in a gas tank and enters the pre-treatment system of a coalbed methane power station. After undergoing four major processes of filtration, dehumidification, pressurization, and cooling, it is sent to the intake pipe of the generator set. It is then filtered through a gas filter and regulated by a pressure regulating valve before being mixed with clean air in a mixer. It then enters the turbocharger and flows into the throttle valve. Due to the temperature rise of the mixer after turbocharging, the mixer passing through the throttle valve is first cooled by the intercooler, and then enters the combustion chamber through the intake manifold to do work and drive the generator to generate electricity.

　　(1)草莓视频黄色网站在启动前应对燃气的浓度、压力、湿度进行检查，基本要求为浓度≥30%，压力为 10~35kPa，湿度≤80%，否则机组将无法启动。

　　(1) Before starting the generator set, the concentration, pressure, and humidity of the gas should be checked. The basic requirements are a concentration of ≥ 30%, a pressure of 10-35kPa, and a humidity of ≤ 80%. Otherwise, the unit will not be able to start.

　　(2）若启动机组未点火报出“超限盘车”故障，说明机组在启动过程中是由燃气的供应量不足导致，首先应检查空燃比设定数值是否合理，其次应注意在盘车时燃油压力的数值是否有变化，若无则说明燃气在管路输送的过程中有中断的地方，检查进气手动阀和燃气电磁阀是否打开。

　　(2) If the starting unit fails to ignite and reports a "over limit turning" fault, it indicates that the unit was started due to insufficient gas supply. Firstly, check whether the air-fuel ratio setting value is reasonable. Secondly, pay attention to whether the fuel pressure value changes during turning. If not, it indicates that there is an interruption in the gas delivery process in the pipeline. Check whether the intake manual valve and gas solenoid valve are open.

　　(3）如果机组正常启动并网后功率不足或功率出现较大范围波动，要确认机组排气温度是否正常。

　　(3) If the power of the unit is insufficient or fluctuates significantly after normal start-up and grid connection, it is necessary to confirm whether the exhaust temperature of the unit is normal.

　　如果排气温度较高，则可能是空气滤芯堵塞，混合气内空气不足引起，应及时更换空气滤芯；

　　If the exhaust temperature is high, it may be caused by a clogged air filter or insufficient air in the mixture. The air filter should be replaced in a timely manner;

　　或燃气燃烧后的气体没有充分排除，也可能导致排气温度升高，检查涡轮增压器是否正常工作；

　　If the gas after combustion is not fully eliminated, it may also cause an increase in exhaust temperature. Check if the turbocharger is working properly;

　　如果排气温度正常，则通过卡连接特电子技师（ET）检查燃油压力的数值，若此数值经常性出现低于 95 则说明燃气管路堵塞，需要进一步根据管路上的压力表来分段判断具体部位出现堵塞，并及时处理。

　　If the exhaust temperature is normal, check the fuel pressure value through the electronic technician (ET) connected to the card. If this value frequently drops below 95, it indicates that the gas pipeline is blocked. Further segmentation is needed based on the pressure gauge on the pipeline to determine the specific locations of the blockage and handle it in a timely manner.
