?發電機組換件修補是很重要的一個環節，零部件選取的是否適宜、修補技能是否正確都與發電機組能否正常作業嚴密相關。下面來介紹下瓦斯發電機組換件修理的經驗：

The replacement and repair of generator set is a very important link. Whether the selection of parts is appropriate and the repair skills are correct are closely related to whether the generator set can operate normally. The following is the experience of replacement and repair of gas generator set:

1、裝配須注意清潔。若裝配時機體內部混械雜質和塵土、油泥，不僅會加快零件磨損，而且還容易引起油路堵塞，產生燒瓦抱軸等事故。如更換新噴油器時須在80℃的干凈中清除防銹油，并作滑動試驗后再裝配使用。

1. Pay attention to cleaning during assembly. If there are mixed mechanical impurities, dust and oil sludge in the body during assembly, it will not only accelerate the wear of parts, but also easily cause the blockage of the oil circuit, and lead to accidents such as burning the bearing and holding the shaft. When replacing a new fuel injector, the antirust oil must be removed in a clean water at 80 ℃, and then assembled for use after a sliding test.

2、注意裝配技術要求。修理人員一般對氣門間隙、軸瓦間隙等是比較重視的，但對有些技術要求卻常常被忽視，如安裝氣缸套時，上平面應高出機體平面0.1毫米左右，否則就會發生氣缸漏氣或連續沖壞氣缸墊的故障。

2. Pay attention to the assembly technical requirements. The repair personnel generally pay more attention to the valve clearance and bearing bush clearance, but some technical requirements are often ignored. For example, when installing the cylinder liner, the upper plane should be about 0.1 mm higher than the plane of the body, otherwise the cylinder will leak or the cylinder gasket will be damaged continuously.

3、注意有些配合件要成對更換。噴油器針閥偶件、柱塞副和出油閥副三大精密偶件要成對更換，這一點一般能做到。但對其它一些配件卻不注意成對更換，如更換齒輪時，只更換磨損較嚴重的一個，裝配后由于嚙合不好，噪聲加大，磨損加劇，使用壽命將大大縮短。又如更換氣缸套時，也應更換活塞和活塞環等。

3. Note that some mating parts should be replaced in pairs. The needle valve pair, plunger pair and outlet valve pair of the fuel injector should be replaced in pairs, which can generally be done. However, some other accessories are not replaced in pairs. For example, when replacing the gear, only one with severe wear will be replaced. After assembly, the service life will be greatly shortened due to poor meshing, increased noise and increased wear. For example, when replacing the cylinder liner, the piston and piston ring should also be replaced.

4、變型產品的零部件不一定通用。有的機廠生產某種型號的變型產品的不少零部件是不通用的。如S195B型機的曲軸，主軸承、缸套、活塞、進排氣門、氣門導管和氣門彈簧等零部件不通用。

4. Parts of variant products are not necessarily universal. Some machine factories produce many parts of a certain type of variant products that are not universal. For example, the crankshaft, main bearing, cylinder liner, piston, intake and exhaust valve, valve guide and valve spring of S195B engine are not universal.

5、同一型號的不同加大件(配件)不通用。在采用修理尺寸法時，可選用加大尺寸的零件，但須認準是加大哪一級的零件。如次磨曲軸后只能選用加大0.25毫米的軸瓦，若選用加大0.5毫米的軸瓦，軸瓦的刮削量加大，不僅浪費時間，而且保證不了修理質量，也會大大降低軸瓦的使用壽命。

5. Different enlarged parts (accessories) of the same model are not common. When the repair dimension method is adopted, the parts with larger size can be selected, but it is necessary to identify which level of parts are enlarged. For example, after grinding the crankshaft, only the bearing bush with an increase of 0.25 mm can be selected. If the bearing bush with an increase of 0.5 mm is selected, the scraping amount of the bearing bush will increase, which not only wastes time, but also can not guarantee the repair quality, and will greatly reduce the service life of the bearing bush.

6、防止零件錯裝、漏裝。就單缸機而言就有一千多個零件，而且大多數有一定的安裝位置及方向要求，如不注意，就容易錯裝或者漏裝。如渦流室鑲塊位置裝反，燃油不能直接通過起動噴孔，使發動機起動困難或根本不能起動。

6. Prevent wrong and missing parts. For single-cylinder engines, there are more than 1000 parts, and most of them have certain installation position and direction requirements. If you do not pay attention, it will be easy to install or miss. If the swirl chamber insert is installed reversely, the fuel cannot directly pass through the starting nozzle, making it difficult or impossible for the engine to start.
