发动前的准备:发动前先查看调整好整个机组的情况,各个组件的衔接及固定有必要牢靠无误,发动机的冷却水系,电发动系统都衔接牢靠,不滴漏、不松脱,开关灵敏,润滑系杰出,燃气供应系以及点火系都确认正常,否则要立即检修、调整正确方可发动。

Preparations before start-up: check and adjust the whole unit before start-up, the connection and fixing of each component must be reliable, the cooling water system of the engine and the electric power system are firmly connected, no drip, no loosening, the switch is sensitive, the lubrication system is outstanding, the gas supply system and the ignition system are confirmed to be normal, otherwise the engine can be started only if it is repaired and adjusted correctly immediately.

发动后的怠速运转:全部准备正常后,翻开燃气阀门,接上发动电源,翻开钥匙,按下按钮,就可发动机组。当机组发动后,立刻留意机油压力表,必定确保有正常的机油压力,万万不可粗枝大叶。发动后要怠速运转一段时间,一是用以调查遍地、各部件的运转情况是否异常,有无异常声响,有问题立刻处理、处理。怠速运转也是用来使机器升温,特别是冬季,这升温是十分必要的,将十分有利于机器的运用。

After starting idle operation: after all ready for normal, turn on the gas valve, connect the power supply, turn on the key, press the button, you can engine group. When the unit is started, pay attention to the oil pressure gauge immediately. It must ensure that there is normal oil pressure. Never be careless. After starting, idle operation should be carried out for a period of time. First, it is used to investigate whether the operation of all parts is abnormal, whether there is abnormal sound, and deal with problems immediately. Idle speed is also used to make the machine warm up, especially in winter, which is very necessary, will be very conducive to the use of the machine.

正常的负载输出:当经怠速调查,且机组已达到了必定的温度(调查水温表即可)就可以操纵电调“油门”将机组升速到标定的工作转速,调整机组的电压和频率都达到标定值,则可向外界合闸,输出负载。为了确保合闸时外界有负载运用,建议合闸前交将空车的转速(频率)稍稍偏高些。负载变化时,留意调速“油门”手柄,即电子调速器的电位器,适应输出,确保电压和频率的安稳。

Normal load output: When the idle speed is investigated and the unit has reached a certain temperature (the water thermometer can be investigated), the "throttle" can be operated to speed up the unit to the calibrated working speed, and the voltage and frequency of the unit can reach the calibrated value, then the unit can be closed to the outside world and the load can be output. In order to ensure that the external load is used when closing, it is suggested that the speed (frequency) of the empty car should be slightly higher before closing. When the load changes, pay attention to the governor "throttle" handle, that is, the potentiometer of the electronic governor, to adapt to the output, to ensure the stability of voltage and frequency.

1、燃气发电机组机房应远离明火区域;

1. The engine room of gas-fired generating units should be far away from the open fire area.

2、燃气发电机组机房应宽敞、亮堂且要求装置换气扇以确保杰出的通风;

2. The engine room of gas-fired generating units should be spacious and bright, and ventilation fans should be installed to ensure excellent ventilation.

3、燃气发电机组装置时底盘与地基使用平垫铁找平。接触面积应在60%以上,且分布均匀;

3. Flat cushion iron is used to leveling chassis and foundation when gas generator is assembled and installed. The contact area should be more than 60% and evenly distributed.

4、室内装置照明、开关、线路及其电器应选用防爆措施,且固定结实;

4. Explosion-proof measures should be adopted for indoor lighting, switches, circuits and electrical appliances, and they should be fixed and firm.

5、燃气发电机组机房内应符合消防要求,配备灭火器等消防器械;

5. Fire extinguishers and other fire extinguishers should be equipped in the engine room of gas-fired generating units.

6、燃气发电机组机房内装置可燃气体报警装置,可燃气体泄露时能及时发现;

6. A flammable gas alarm device is installed in the engine room of a gas-fired generating unit, which can be detected in time when the flammable gas leaks.

7、60kw以下单台燃气发动机燃气管路的外部首要管道内径应不小于2吋,靠近发动机的部分内径应不小于1吋!60kw以上燃气发电机组则分别是3吋和两吋。且有必要装置燃气阀门(不锈钢球阀)、型放水阀、防回火装置,燃气管路焊接完成应整理焊渣(用高压空气);

The inner diameter of the main external pipeline of a single gas engine under 7 and 60 kW should be no less than 2 inches, and the inner diameter of the part near the engine should be no less than 1 inch. Gas-fired generating units above 60 kW are 3 inches and 2 inches respectively. It is also necessary to install gas valves (stainless steel ball valves), type drain valves and anti-tempering devices. The welding slag (high pressure air) should be sorted out after gas pipeline welding.

8、燃气有必要脱硫、脱水、除尘,其中含流量≤0.25Nm3,氢气≤10%;

8. It is necessary to desulfurize, dehydrate and dust the gas, which contains less than 0.25Nm3 flow rate and less than 10% hydrogen.

9、燃气发电机冷却水有必要用软化水。

9. It is necessary to use softening water for cooling water of gas generator.
