浙江杭州宁波温州嘉兴湖州绍兴金华舟山柴油发电机维修[教育] 柴油发动机怎样维修保养 How to repair and maintenance of diesel engine 季节性保养检查内容中，有一些项目可能或不可能归入按照行车里程数或工作小时数来确定的保养日程中， 但下述内容在一年内需进行一次或两次。 Seasonal maintenance inspection content, some projects may or may not be classed as according to the driving mileage or hours of work to determine the maintenance schedule, but the following a year inside need one or two times. (一)清洗冷却系(秋季) ( a ) cleaning cooling system ( Autumn) 冷却系必须清洁以使其工作正常。系统中的水垢降低了它从水套吸收的热量和向散热器排出的热量。使用 清洁的水以避免堵塞散热器和缸体中几百条细小的水道。对于被水垢和沉积物堵塞了的散热器芯、加热器 芯、机油冷却器和汽缸体中的水道，用化学清洗剂清洗、中和和冲洗。 The cooling system must be clean and in order to make it work properly. System scale reducing it from the water jacket heat to the radiator heat. The use of clean water to prevent clogging radiator and cylinder of hundreds of tiny channel. The scale and sediment blocking the radiator core, a heater core, oil cooler and a cylinder body of water, with chemical cleaning agent cleaning, neutralization and washing. 1(化学清洗 如果铁锈和水垢多了，就应对系统进行化学清洗。使用一种好的冷却系清洗剂，如硫酸氢钠 或草酸，然后是中和剂和冲洗。 The 1 chemical cleaning if rust and scale more, addressing system for chemical cleaning. The use of a good cooling system cleaning agent, such as sodium or oxalic acid, and neutralizing agent and flushing. 2(压力冲洗 2pressure washing 在加人防冻剂之前先要冲洗散热器和汽缸体，或在用过的或大修过的柴油机上加装水过滤器。 In addition to antifreeze before flushing the radiator and the cylinder body, or in used or overhaul of diesel engine with water filter. 压力冲洗散热器时，打开上下软管接头并拧紧散热器盖。在上下水管接头上使用软管接头可以方便工作。 将水枪喷嘴连到下水管让水充满散热器。然后逐步加大气压以免胀裂散热器芯子。停止进气，让散热器重 新进满水，然后又加气压，如此反复进行，直到从散热器出来的水变清为止。 Pressure flush radiator, open the hose connector and tighten the radiator cap. In the upper and lower water pipe joints using a hose joint can be convenient to work. The water gun nozzle connected to a sewer pipe to let the water filled with radiator. Then gradually increase the pressure to avoid splitting the radiator core. Air, let the radiator to water flooded into, and then added pressure, so repeatedly, until the flowing out from the heat radiator water clean. 注意;在开始使水流出时不要使用过大的气压，以免胀裂散热器芯子。 Attention; at the beginning of the water outflow when do not use too much pressure, so as to avoid splitting the radiator core. 沉积物和脏物，除了积沉在散热器芯子中外，也沉积在汽缸体的槽、坑中。卸下节温器，用水冲洗汽缸体， 将下面出水口关小直到汽缸体中充满了水。施加空气压力迫使水从下面出水口流出。如此反复进行，直到 流出的水变清为止。 Sediment and dirt, in addition to deposition in the radiator core joint, also deposited in the cylinder groove, pit. Remove the thermostat, the rinse water cylinder body, the water outlet to close small until the cylinder body filled with water. Applying air pressure forces the water from below the water outlet. So repeatedly, until out of the water clean. (二)更换水管(需要时) ( two) to replace the pipe ( when needed) 检查机油滤清器和冷却系统的软管和软管接头，看有无渗漏及损坏。损坏了的软管的碎片进入冷却系统或 润滑系统会限制甚至堵塞散热器芯子的细小水道和机油冷却器，部分地停止了循环，所以需要时更换之。 Check the engine oil filter and cooling system of the hose and hose connections, see there is no leakage and damage. Damage to the hose fragments into the cooling system and lubrication system can limit or even blocked radiator core small waterways and oil cooler, partially stopped circulation, so need replacement. 三)检查冷起机预热器(秋季) Three) check the cold engine preheater ( Autumn) 从进气歧管上靠近电热塞处卸下1,8in管螺塞，按第(一)部分所述检查预热器工作情况。 From the intake manifold near the electric plug unloaded 1/ 8in pipe plug, according to article ( a ) part of the examination work of preheater. 检查自动百叶窗和自动风扇(秋季) Check the automatic shutter and automatic fan ( Autumn) 自动百叶窗和自动风扇的开关温度应当调到所使用的节温器开关温度范围。表11—24为一般使用的自动 百叶窗和自动风扇的调整范围。82,91~C(180,195~F)的节温器只和在86~C关闭、在91~C打开的自动 百叶窗配套工作。 Automatic shutter and automatic fan switch temperature shall be transferred to the thermostat switch temperature range. Table 11 -24for the general use of the automatic shutter and automatic fan adjustment range. 82~ 91~C (180~ 195~F ) thermostat only and is closed at 86~C, in 91~C open automatic shutter supporting work. (四)检查节温器和密封垫(秋季) ( four) examined the thermostat and the sealing pad ( Autumn) 从节温器壳上取下节温器，检查它的开关温度(表11—24)。 From the thermostat housing with the thermostat, check its switch temperature (11- 24). 大多数康明斯柴油机装备77,85~C(170,185~F)中温节温器和71,79~C(160,175~F)低温节温器，在 少数情况下由于柴油机使用情况而装备82,91~C(180—195~F)高温节温器。 The majority of Cummins diesel engine equipped with 77, 85~C (170 , 185~F) temperature thermostat and 71~ 79~C (160~ 175~F ) low temperature thermostat, in a minority of cases due to diesel engine usage and equipment from 82 to 91~C (180,195~F ) high temperature thermostat. (五)用蒸汽清洗柴油机(春季) ( five) steam cleaning of diesel engine (spring ) 蒸汽清洗是清洗脏的柴油机或装备的最有效的方法。如果没有蒸气，可使用规定的溶剂清洗柴油机。 Steam cleaning is a cleaning dirty diesel engine or equipment is the most effective method. If there is no steam, can be provided for the use of the solvent cleaning diesel engine. 勿受冲洗喷嘴全部力量的冲击，要保护好所有电气部件和电线。 Not affected by flushing nozzles of the full force of the impact, to protect all electrical components and wires. (六)检查柴油机悬挂装置(春季) ( six) check the diesel engine suspension device (spring ) 柴油机安装螺栓偶尔也会松动使得柴油机悬挂装置和支架很快磨损。因此，需要时上紧所有的螺栓和螺母， 损坏的更换，丢失的补上。 Diesel engine mounting bolts loose occasionally makes diesel engine suspension device and a bracket soon wear. Therefore, need to tighten all bolts and nuts, replacement of damaged, lost to fill. (七)紧固涡轮增压器安装螺母(需要时) ( seven) for fastening turbocharger mounting nut ( when needed) 拧紧所有涡轮增压器安装螺钉和螺母，并查明它们是否确实上紧。上紧安装螺栓和支架可将振动减至最小。 Tighten all the turbocharger mounting screws and nuts, and ascertain whether they really tight. Tighten mounting bolts and the bracket can be reduced to the minimum vibration. (八)检查风扇和皮带轮的安装 (春季) ( eight) : check the fan belt pulley and installation (spring ) 检查风扇是否牢固装好，需要时上紧固定螺钉。检查风扇有无晃动或叶片弯曲。 Check fan is firmly installed, need to tighten set screw. Check fan has no shake or curved blades. 检查风扇毂和曲轴皮带轮是否牢固装好。检查风扇毂皮带轮有无松动和晃动;必要时拆下风扇导向毂来上 紧轴上螺母。上紧风扇支架螺钉。 Check the fan hub and a crank pulley is tightly fitted. Check the fan hub pulley is loose and sway; when necessary, remove the fan hub nut for tightening shaft guide. A fan bracket screws. (九)检查曲轴端隙(春季) ( nine) to check that the crankshaft end gap (spring ) 新的或大修过的柴油机的曲轴端隙应符合表(11—25的规定。磨损了的柴油机的端隙 如果超过表上的磨 损极限，就不能使用。如果柴油机拆开进行修理，就装上新的止推环。 New or reconditioned diesel engine crankshaft end gap should accord with the regulations in table .11 - 25regulations. Wear of diesel engine side if more than a table on the wear limit, cannot use. If the engine apart to repair, will install new thrust ring. 注意:不能抵住减振器外环来撬动。 Note: cannot withstand shock absorber outer ring to move. 检查端隙的办法是将千分表指针抵住扭转减振器或皮带轮的端面，然后抵住减振器或皮带轮的内部和前盖 来撬动。当柴油机装在机组上并和变速器或变扭器装在一起时，必须有端隙。 Check end gap approach is a dial gauge pointer to resist torsional vibration damper or pulley end, then resist the shock absorber or pulley inner and a front cover to move. When the diesel engine is installed in the machine and gearbox or a torque converter mounted together, must have the end clearance. (十)检查热交换器锌塞(春季) ( ten) examination of heat exchanger of Zinc Slug (spring ) 检查热交换器锌塞，如严重腐蚀就要更换。更换的频繁度决定于在热交换器中循环生水的化学反应情况。 Inspection of heat exchanger of Zinc Slug, such as severe corrosion should be replaced. Replacement frequently depends on the heat exchanger circulating water chemistry conditions.
