We have entered a tense and orderly working state again. At this time, if the natural gas generator unit suddenly does not rotate, it will bring great trouble to the work, especially the production and manufacturing units. If we delay the work, we will delay the delivery date. This is a loss for the manufacturer. Therefore, if the natural gas generator unit suddenly does not rotate, it is necessary to come up with a reasonable and effective solution. Generally speaking, the sudden non rotation of natural gas generator set is due to the following two aspects:

1.是较长时间停放后一次启动，发电机不能转动。

1. The generator cannot rotate when it is started after parking for a long time.

2.天然气发电机组在运行中出现异常响声突然熄火，再启动时发电机不能转动。

2. The natural gas generator unit suddenly stalls due to abnormal noise during operation, and the generator cannot rotate during restart.

如果出现上述两个方面的问题，我们应当考虑是什么原因导致造成的。

If the above two problems occur, we should consider what causes them.

1.燃气发电机组在运行过程中突然出现异响并导致熄火，原因多为：抱瓦、黏缸、曲轴或连杆折断导致发电机不能启动。如果进气门和出气门卡死，以至于不能进气、出气，或者是活塞项部有异物，也会造成启动时发电机不转动而无法启动。

1. Abnormal noise occurs suddenly during the operation of gas-fired generator unit and leads to flameout. The main reasons are: bearing, sticking cylinder, broken crankshaft or connecting rod, resulting in failure to start the generator. If the inlet valve and outlet valve are stuck so that the inlet and outlet cannot be started, or there is foreign matter at the piston neck, the generator will not rotate and cannot be started during startup.

2.天然气发电机组如果停滞长时间不用，一次使用也会出现故障：比如蓄电池极柱接触不良，启动线路未接通或蓄电池线路内部断路，线路不通；蓄电池存电量不足，不能带动启动机旋转等。或启动线路本身有断路之处；启动机磁力开关有故障；启动机齿轮未能与发电机飞轮齿圈啮合而导致启动不了。

2. If the natural gas generator set is not used for a long time, it will also fail in one use: for example, the battery pole is in poor contact, the starting line is not connected, or the internal circuit of the battery line is open, and the line is not connected; The storage capacity of the battery is insufficient to drive the starter to rotate, etc. Or there is an open circuit in the starting line itself; The magnetic switch of the starter is faulty; The starter gear fails to mesh with the flywheel ring gear of the generator, resulting in failure to start.

如果天然气发电机组突然不转动了，我们可以以以下两种方式调整：

If the natural gas generator set suddenly stops rotating, we can adjust it in the following two ways:

一是可分别对极柱，蓄电池线路、启动机磁力开关、启动线路进行检修。

First, the pole column, battery circuit, starter magnetic switch and starting circuit can be overhauled respectively.

二是针对上述可能出现的故障部位，应分别拆检发电机曲轴箱、气门室罩盖以及汽缸盖。

Second, for the above possible fault parts, the generator crankcase, valve cover and cylinder head shall be disassembled and inspected respectively.
