瓦斯发电机组拆卸需要遵守哪些原则?

返回 2021.09.10 来源:http://www.huannengpower.com
瓦斯发电机组的拆卸工作看起来简单,实际上并不是一件很容易的事情。如果不注意各零件间的连接关系以及拆卸方法,很可能会造成机组零件的损坏,从而影响修理工作的正常进行。那么瓦斯发电机组拆卸需要遵守哪些原则?
The disassembly of gas generator set looks simple, but in fact it is not an easy thing. If you do not pay attention to the connection relationship between parts and the disassembly method, it is likely to cause damage to the parts of the unit, thus affecting the normal progress of repair work. So what principles should be observed in the disassembly of gas generator set?
1.放净柴油、机油及冷却水
1. Drain the diesel, engine oil and cooling water
2.坚持先外部后内部,先附件后主体,先拆连接部们后拆零件,先拆总成后拆组合件、合件及零件的原则。
2. Adhere to the principle of external first and then internal, accessories first and then main body, connecting parts first and then parts, assembly first and then assemblies, assemblies and parts.
拆卸的注意事项
Precautions for disassembly
1.一定在机器完全冷却的情况下进行。否则由于热应力的影响,会使气缸体、气缸盖等机件产生变形、致使影响内燃机的各种性能。
1. It must be carried out when the machine is completely cooled. Otherwise, due to the influence of thermal stress, the cylinder block, cylinder head and other parts will be deformed, which will affect the performance of the internal combustion engine.
2.在拆卸气缸盖、连杆轴承盖、主轴承盖等零部件时,其螺栓或螺母的松开,必 须按一定次序对称均匀地分2~3次拆卸。不允许松完一边再松另一边的螺母或螺栓,否则,由于零件受力不均匀而使零件产生变形,有的甚至产生裂纹而损坏。
2. When disassembling cylinder head, connecting rod bearing cap, main bearing cap and other parts, the bolts or nuts must be disassembled symmetrically and evenly for 2 ~ 3 times in a certain order. It is not allowed to loosen the nut or bolt on the other side after loosening one side, otherwise the parts will be deformed due to uneven stress, and some will even be damaged due to cracks.
3.认真做好核对记号工作。对有记号的零件记下来,没有记号的应做上记号。记号应打在易于看到的非工作面上,不要损伤装配基准面,以便尽量保持机器原有的装配关系。有些零件,如发电机上各导线的接头等,可用挂牌子等方法进行标号。
3. Carefully check the marks. Note down the marked parts, and mark those without marks. The mark shall be marked on the easily visible non working surface without damaging the assembly datum plane, so as to maintain the original assembly relationship of the machine as far as possible. Some parts, such as the connector of each conductor on the generator, can be labeled by hanging a brand and other methods.
4.拆卸时不能猛敲打,正确使用各种工具,特别是专用工具。比如,拆卸活塞时应尽量使用活塞环装卸钳,拆卸火花塞应使用火花塞套筒,且用力不能过猛。否则容易使自己的手受伤,并且容易损坏火花塞。
4. Do not knock violently during disassembly, and use various tools correctly, especially special tools. For example, piston ring handling pliers shall be used as much as possible when removing the piston, and spark plug sleeve shall be used when removing the spark plug, and the force shall not be too strong. Otherwise, it is easy to hurt your hand and damage the spark plug.
除此之外,拆卸前的准备工作也十分重要。比如说准备好各种工具:开中扳手、梅花扳手、活动扳手、十字旋具、手钳、手锤等;准备好维修配件及各种垫片等等。
In addition, preparations before disassembly are also very important. For example, prepare all kinds of tools: middle wrenches, ring wrenches, adjustable wrenches, cross screwdrivers, pliers, hammer, etc; Prepare maintenance parts and various gaskets, etc.
