　　1.燃气91看片神器下载内燃机的中修

　　1. Intermediate maintenance of internal combustion engine in gas generator set

　　内燃机中修使邻近大修间的一次有计划性的修理，主要是为了平衡各机件间使用期限的不同，以保证或延长大修的间隔时间。其作业范围介于小修与大修之间，一般情况下是更换或维修1～2各主要总成，同时检查其余总成的技术状况，并排除故障，进行必要的紧定和调整工作。

　　Internal combustion engine maintenance refers to a planned repair between adjacent major maintenance rooms, mainly to balance the different service life of various components, in order to ensure or extend the interval between major maintenance. Its scope of work is between minor and major repairs, generally involving replacing or repairing 1-2 major assemblies, while checking the technical condition of other assemblies, troubleshooting, and performing necessary tightening and adjustment work.

　　【燃气91看片神器下载中修基本内容是】：更换机油和燃油滤清器的滤芯；调整喷油泵（高压油泵）和喷油器（嘴）的喷油质量，研磨出油阀组件；拆修活塞连杆组、调速器、水泵和机油泵等；更换活塞、连杆铜套。轴瓦、气门、气门弹簧及锁片等；校正发动机压缩比等。

　　The basic content of repairing a gas generator set is to replace the oil and fuel filter elements; Adjust the fuel injection quality of the fuel injection pump (high-pressure fuel pump) and fuel injector (nozzle), and grind the fuel valve assembly; Dismantle and repair piston connecting rod assembly, governor, water pump, and oil pump, etc; Replace the piston and connecting rod copper sleeve. Bearing shells, valves, valve springs, and locking plates, etc; Correct engine compression ratio, etc.

　　2.发电机的中修流程

　　2. Medium repair process of generator

　　发电机的中修为每半年左右或其累计工作满1000h进行。除完成发电机小修的内容外，还有如下内容：检查滑环和电刷装置、检查滑环（或换向器）和电刷装置的状况，进行必要的情节、修正和测量。

　　The maintenance of the generator should be carried out every six months or after a total of 1000 hours of operation. In addition to completing minor repairs on the generator, there are also the following tasks: checking the slip ring and brush device, inspecting the condition of the slip ring (or commutator) and brush device, and making necessary adjustments, corrections, and measurements.

　　① 清洁工作

　　① Cleaning work

　　集电环或换向器、电刷和刷握各接触导电表面应无油、无垢、无碳末、光洁明亮并接触良好。

　　The contact conductive surfaces of the collector ring or commutator, brush and brush holder should be free of oil, dirt, carbon powder, smooth and bright, and have good contact.

　　【注意】：擦拭时，要用柔软、干燥、清洁而无毛头的布块，可蘸少许汽油（或酒精）。尤其注意刷握内和集电环或换向器的根部（焊线头的肩部下面）和云母槽内的清洁。

　　【 Attention 】: When wiping, use a soft, dry, clean and lint free cloth, which can be dipped in a little gasoline (or alcohol). Pay special attention to cleaning the inside of the brush holder, the root of the collector ring or commutator (under the shoulder of the welding wire head), and the mica groove.

　　② 磨光与修圆

　　② Polishing and rounding

　　集电环和换向器的外圆表面应十分光滑，一般呈暗棕色。若发现有烧伤痕迹、发黑或轻微的机械划伤等应进行磨光。其方法是：用00号细玻璃砂纸（或金刚砂布）一条，再找一块宽度合适的硬木板，用木板把砂纸压紧在集电环或换向器外圆面上，然后低速转动电机转子，一直磨到外圆面光滑为止，最后进行认真的清洁工作。

　　The outer surface of the collector ring and commutator should be very smooth, generally dark brown in color. If burn marks, blackening, or minor mechanical scratches are found, they should be polished. The method is to use a piece of 00 grit fine glass sandpaper (or diamond cloth), then find a suitable width hardwood board, press the sandpaper onto the outer surface of the collector ring or commutator with the wooden board, and then rotate the motor rotor at low speed until the outer surface is smooth, and finally perform a thorough cleaning work.

　　【注意】：磨光操作中，注意切断定、转子绕组的电路，以免触电或带电运转。如机电环或换向器外面面灼伤严重或者失圆（已不是正常的圆柱形而摇摆严重时），应当取出转子，在车床上转车外圆面——修圆，注意其表面粗糙度达到要求，修圆后的换向器还要下刻云母片，并进行清洁处理。

　　[Attention]: During the polishing operation, pay attention to cutting the circuit of the rotor winding to avoid electric shock or live operation. If the outer surface of the electromechanical ring or commutator is severely burned or out of roundness (when it is no longer a normal cylindrical shape and swings severely), the rotor should be removed and the outer surface of the commutator should be turned on a lathe - rounding, paying attention to its surface roughness to meet the requirements. After rounding, the commutator should also be engraved with mica sheets and cleaned.

　　③ 下刻云母片

　　③ Engraved mica flakes

　　换向器片间的云母片的高度，正常是应比换向片低0.5～1.2mm，否则应考虑下刻。其方法是：在现场条件下，可用细齿的手锯钢锯条的一段，自制一个前端带钩的小刀，沿云母片沟逐渐下刻，使之高度符合要求为止。

　　The height of the mica pieces between the commutator segments should be 0.5-1.2mm lower than the commutator segments, otherwise the next engraving should be considered. The method is to use a fine toothed hand saw to cut a section of the steel saw blade under on-site conditions, and make a small knife with a hook at the front end. Gradually cut along the mica groove until the height meets the requirements.

　　【注意】：下刻时刀子要锋利，用力要均匀、平稳，下刻完毕要进行磨光和清洁。

　　[Attention]: When engraving, the knife should be sharp, and the force should be even and steady. After engraving, it should be polished and cleaned.

　　④ 电刷装置的调整

　　④ Adjustment of electric brush device

　　电刷是以石墨为主料压制成型的，导电性能好且耐磨，但质脆，不耐重压或撞击。电刷安放在刷握内，要求能上下自由平稳的移动，左右不应有明显的晃动现象，下端面与集电环或换向器的接触面积不小于3/4，且光滑、平整，工作时无跳动，磨损量不应超过电刷原来总高度的2/3。否则应加以调整、研磨或更换电刷。

　　Electric brushes are mainly made of graphite and pressed into shape, with good electrical conductivity and wear resistance, but they are brittle and not resistant to heavy pressure or impact. The electric brush should be placed inside the brush holder and should be able to move freely and smoothly up and down without obvious shaking. The contact area between the lower end face and the collector ring or commutator should not be less than 3/4, and it should be smooth and flat. There should be no jumping during operation, and the wear should not exceed 2/3 of the original total height of the electric brush. Otherwise, the electric brush should be adjusted, ground or replaced.

　　【注意】：电刷和刷握等是与集电环或换向器配套的，更换时不得擅自更换牌号和规格。

　　【 Attention 】: Electric brushes and brush holders are matched with collector rings or commutators, and should not be replaced with different grades and specifications without authorization.

　　⑤ 电刷的研磨

　　⑤ Grinding of electric brushes

　　新电刷或接触面已烧蚀的电刷，必须经过研磨，使之与集电环或换向器贴合良好才能使用。研磨接触面的方法：用00号砂纸一条，让有砂的一面对着电刷，把无砂的一面包着（最好粘住）集电环或换向器的外圆上，并让电刷弹簧压紧电刷，一电机正常运行的方向——逆时针方向转动转子，直到电刷下端面有80%以上与集电环外圆密切接触为止。电刷磨好后不应调换它的安装方向或更换刷握。正是使用前，应经过2～3min的空载磨合，然后再逐渐增加电负荷。

　　New electric brushes or brushes with burnt contact surfaces must be ground to ensure a good fit with the collector ring or commutator before use. Method for grinding the contact surface: Use a piece of 00 grit sandpaper, with the sandy side facing the electric brush. Cover (preferably stick) the non sandy side onto the outer circle of the collector ring or commutator, and press the electric brush spring tightly against the brush. Rotate the rotor counterclockwise in the direction of normal motor operation until more than 80% of the lower end face of the brush is in close contact with the outer circle of the collector ring. After the electric brush is ground, its installation direction or brush holder should not be changed. Before use, it should undergo 2-3 minutes of no-load running in, and then gradually increase the electrical load.

　　全面检查和清洗轴承，中小型电机的转子一般采用滚动轴承，都是用润滑脂润滑，通常，普通型电机采用ZGN-3钙基润滑脂，湿热型电机采用ZL-3锂基轴承脂。一般情况下，电机连续运行1500h左右时，应更换润滑脂，以确保电机正常运行。轴承的工作好坏，直接影响电机的运行可靠性，因此应当注意维护和保养。

　　Thoroughly inspect and clean the bearings. The rotors of small and medium-sized motors generally use rolling bearings, which are lubricated with grease. Generally, ordinary motors use ZGN-3 calcium based grease, while wet heat motors use ZL-3 lithium based bearing grease. In general, when the motor runs continuously for about 1500 hours, the lubricating grease should be replaced to ensure the normal operation of the motor. The performance of bearings directly affects the reliability of motor operation, so maintenance and upkeep should be taken into account.

　　检查电机及各绕组的绝缘 全面检查电机及各绕组的绝缘情况，检查个电气及机械的连接情况。

　　Inspect the insulation of the motor and its windings comprehensively, and check the electrical and mechanical connections.

　　燃气91看片神器下载保养和检修完毕后，应复查一次电机各电气连结和机械安装是否正确与牢固，并用干燥的压缩空气吹净电机内部各处。最后，按正常的启动和运行要求，对其进行空载和负载试验，已确定是否完好无误。

　　After the maintenance and repair of the gas generator set is completed, it is necessary to recheck whether the electrical connections and mechanical installation of the motor are correct and firm, and blow all parts inside the motor with dry compressed air. Finally, according to the normal start-up and operation requirements, conduct no-load and load tests on it to determine if it is intact and error free.
