瓦斯发电机组初次运转，长期停放后再次运转或日常工作启动，启动前做好以下工作，使机组处于良好状态。下面来讲讲相关的准备工作吧。

The gas generator set operates for the first time, operates again after long-term parking or starts up for daily work. Before starting, the following work shall be done well to keep the unit in good condition. Now let's talk about the relevant preparations.

（1）机组及配套辅助系统零部件应齐全、完整、各紧固联接部位联接正确、牢固；油、气、水管路密封良好，不泄露，电路安全、可靠。旋转件部位附近不准有杂物。

(1) Components of the unit and supporting auxiliary system shall be complete and complete, and all fastening and connection parts shall be correctly and firmly connected; The oil, gas and water pipelines are well sealed without leakage, and the circuit is safe and reliable. No sundries are allowed near the rotating parts.

（2）润滑系统

(2) Lubrication system

①检查油底壳机油油位是否符合使用规定刻度位置，否则应补加机油。所用机油牌号应符合使用维护说明书规定；亦可用公司批准使用的其他牌号机油。不同牌号的机油不能混用。

① Check whether the oil level of the oil pan conforms to the specified graduation position, or add oil. The brand of oil used shall comply with the provisions of the operation and maintenance manual; Other brands of engine oil approved by the company can also be used. Oils of different brands cannot be mixed.

②当站内环境温度≤5℃时，应将机油预热至20℃，且禁止使用明火预热。

② When the ambient temperature in the station is ≤ 5 ℃, the engine oil shall be preheated to 20 ℃, and open flame preheating is prohibited.

（3）冷却系统

(3) Cooling system

检查膨胀水箱内的冷却液液面是否达到规定位置，同时检查冷却液状况，并根据需要添加防锈油或防冻液等添加剂。当环境温度低时，应将冷却液预热至20℃。

Check whether the coolant level in the expansion tank reaches the specified position, check the coolant condition, and add additives such as antirust oil or antifreeze as required. When the ambient temperature is low, the coolant should be preheated to 20 ℃.

（4）进气系统

(4) Air intake system

①检查气源压力是否符合机组工作规定压力范围，供气管路、阀门是否渗漏并作处理。

① Check whether the air source pressure conforms to the specified pressure range of the unit, and whether the air supply pipeline and valve leak and handle them.

②发电机组进气控制系统是否运动灵活，辅助运动部位应及时补加润滑脂。

② Whether the air inlet control system of the generator set moves flexibly, and the auxiliary moving parts shall be filled with lubricating grease in time.

（5）启动系统

(5) Starting the system

检查启动柜或蓄电池电缆连接是否正确，是否接触良好、紧固可靠。电源应接通。

Check whether the starting cabinet or battery cable is connected correctly, whether it is in good contact and fastened reliably. The power supply should be connected.

（6）盘车

(6) Turning gear

手动或电动预供油，用盘车工具盘转曲轴至少两圈，检查机组曲轴等主要部件是否工作顺畅，不得有卡碰及其他异常现象。

For manual or electric pre oil supply, turn the crankshaft for at least two turns with turning tool, and check whether the main components such as the unit crankshaft work smoothly, without jamming or other abnormal phenomena.

（7）检查相序

(7) Check phase sequence

若机组并网或并联运行，运行前应用相序表进行相序检查，确保机组间的相序或机组与电网的相序相同。

If the units are connected to the grid or operated in parallel, the phase sequence meter shall be used to check the phase sequence before operation to ensure that the phase sequence between the units or between the units and the grid is the same.
