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.是較長時間停放后一次啟動，發電機不能轉動。

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

2.天然氣發電機組在運行中出現異常響聲突然熄火，再啟動時發電機不能轉動。

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

如果出現上述兩個方面的問題，我們應當考慮是什么原因導致造成的。

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

1.燃氣發電機組在運行過程中突然出現異響并導致熄火，原因多為：抱瓦、黏缸、曲軸或連桿折斷導致發電機不能啟動。如果進氣門和出氣門卡死，以至于不能進氣、出氣，或者是活塞項部有異物，也會造成啟動時發電機不轉動而無法啟動。

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.天然氣發電機組如果停滯長時間不用，一次使用也會出現故障：比如蓄電池極柱接觸不良，啟動線路未接通或蓄電池線路內部斷路，線路不通；蓄電池存電量不足，不能帶動啟動機旋轉等。或啟動線路本身有斷路之處；啟動機磁力開關有故障；啟動機齒輪未能與發電機飛輪齒圈嚙合而導致啟動不了。

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.

如果天然氣發電機組突然不轉動了，我們可以以以下兩種方式調整：

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

一是可分別對極柱，蓄電池線路、啟動機磁力開關、啟動線路進行檢修。

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

二是針對上述可能出現的故障部位，應分別拆檢發電機曲軸箱、氣門室罩蓋以及汽缸蓋。

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