1油耗不断增加
1. Increasing fuel consumption
(1)不良反应:搅拌车油耗不断增加。
(1) Adverse reaction: the fuel consumption of mixer truck is increasing.
(2)病情原因:油耗增加的原因很多。但常见又容易被忽略的是对轮胎气压的检查。轮胎胎压不足不仅会导致行驶阻力增加,造成油耗上升,还会影响轮胎的使用寿命。
(2) Cause of illness: there are many reasons for the increase in fuel consumption. But the common and easily overlooked is the inspection of tire pressure. Insufficient tire pressure will not only increase driving resistance and fuel consumption, but also affect the service life of tires.
(3)绿色保养:自备胎压测量器,经常检查轮胎气压。切记不要忘记备胎的检查,以免急需更换备胎时,才发现备胎不能使用。气温高时胎压会比平时高一些,冷天或阴凉处测量的胎压比较准确。轮胎每行驶1万km要互换位置,避免前后磨损程度相差太大。如果需要更换磨损严重的轮胎,好2个或4个一起更换,纹路相同的轮胎可以前后交叉更换。另外,折线花纹的轮胎有助于节省燃油。
(3) Green maintenance: bring your own tire pressure gauge and check the tire pressure frequently. Remember not to forget the inspection of the spare tire, so as to avoid finding that the spare tire cannot be used when it is in urgent need of replacement. When the temperature is high, the tire pressure will be higher than usual. The tire pressure measured in cold days or in the shade is more accurate. The positions of tires shall be changed every 10000 km to avoid too large difference between front and rear wear. If you need to replace seriously worn tires, replace 2 or 4 tires together. Tires with the same grain can be replaced crosswise. In addition, broken line tires help to save fuel.

2动力性能下降
2. Power performance degradation
(1)不良反应:发动机动力性能下降,油耗增加,喷嘴堵塞。
(1) Adverse reactions: the engine power performance decreases, the fuel consumption increases, and the nozzle is blocked.
(2)病情原因:很可能是由于长时间未更换机油、机油滤清器、空气滤清器和汽(柴)油滤清器造成了油料燃烧不充分,发动机积炭较多等而致。
(2) Cause of illness: it is likely that the engine oil, oil filter, air filter and steam (diesel) oil filter have not been changed for a long time, resulting in insufficient oil combustion and more carbon deposition in the engine.
(3)绿色保养:建议机油、机油滤清器,每行驶约5000km更换一次,空气滤清器和汽(柴)油滤清器每行驶1万km时需更换,否则空气、燃油和机油中的杂质会造成零件磨损和油路堵塞,从而影响发动机正常运转。
(3) Green maintenance: it is recommended to replace the engine oil and oil filter every 5000km, and replace the air filter and steam (diesel) oil filter every 10000km, otherwise the impurities in air, fuel and engine oil will cause parts wear and oil circuit blockage, thus affecting the normal operation of the engine.
3冷却液滴漏
3 coolant drip
(1)不良反应:车下滴漏出一滩莫名其妙的液体,且冷却液的液面高度下降。
(1) Adverse reaction: a pool of inexplicable liquid drips out under the car, and the liquid level of coolant drops.
(2)病情原因:通常情况下,造成滴漏的原因是连接冷却液箱和发动机间的橡皮管有裂缝。
(2) Cause of illness: usually, the cause of leakage is a crack in the rubber tube connecting the coolant tank and the engine.
(3)绿色保养:变质的冷却液防锈品质下降,不但容易导致散热器、管路、软管等部件的损坏,而且因冷却液的主要成分是乙二醇,滴漏到地上表2混凝土搅拌车工作装置常见故障分析及排除方法也会造成环境和空气污染。通过目测很难判断冷却液是否变质,所以要定期更换冷却液,切莫等到出现故障再去修理。一般建议混凝土搅拌车每行驶4万km或2年须更换冷却液,另外每2年须更换冷却风扇皮带。
(3) Green maintenance: the deterioration of the antirust quality of the coolant will not only easily lead to the damage of the radiator, pipeline, hose and other components, but also cause environmental and air pollution because the main component of the coolant is ethylene glycol, which drips to the ground. Table 2 common fault analysis and troubleshooting methods of the working device of the concrete mixer will also cause environmental and air pollution. It is difficult to judge whether the coolant is deteriorated by visual inspection, so replace the coolant regularly and do not wait until there is a fault. It is generally recommended that the coolant of the concrete mixer should be replaced every 40000 km or 2 years, and the cooling fan belt should be replaced every 2 years.
4发动机不启动
4 engine does not start
(1)不良反应:多次点火,发动机不启动。
(1) Adverse reaction: multiple ignition, engine does not start.
(2)病情原因:发动机启动是靠电瓶的电流推动火花塞点火完成,因而启动系统出现故障,很可能是由于电瓶生锈或者电瓶液滴漏造成。
(2) Cause of illness: the ignition of the spark plug is completed by the current of the battery when the engine is started. Therefore, the failure of the starting system may be caused by the rust of the battery or the dripping of battery liquid.
(3)绿色保养:每1~2个月要查看电瓶内的电瓶液是否充足。如果不足,可添加蒸馏水至适当高度。目前乘用车大都采用免维护电瓶,不可擅自加水。此外,每年都要检查一下电瓶的正负端接点有无生锈或污浊的现象。
(3) Green maintenance: check whether the battery liquid in the battery is sufficient every 1 ~ 2 months. If not enough, add distilled water to the appropriate height. At present, most passenger cars use maintenance free batteries, and water cannot be added without authorization. In addition, check whether the positive and negative terminal contacts of the battery are rusty or dirty every year.

5排气噪声增加
5 increase of exhaust noise
(1)不良反应:发动机排气的噪声增加,废气排放量也超标。
(1) Adverse reaction: the noise of engine exhaust increases and the exhaust emission exceeds the standard.
(2)病情原因:发动机的废气经高温发生氧化作用,很可能导致排气系统泄漏。
(2) Cause of illness: the exhaust gas of the engine is oxidized at high temperature, which is likely to lead to leakage of the exhaust system.
(3)绿色保养:检查排气系统的管路、接口处(特别是消音器)是否被废气腐蚀,接口垫有没有被冲坏。若发现排气系统泄漏应及时修理或更换泄漏部件。每年检查1次不仅可以保证排气系统正常运转,更重要的是减少尾气对环境的污染。
(3) Green maintenance: check whether the pipelines and interfaces of the exhaust system (especially the muffler) are corroded by waste gas and whether the interface pad is washed out. If the exhaust system leaks, repair or replace the leaking parts in time. Checking once a year can not only ensure the normal operation of the exhaust system, but also reduce the pollution of tail gas to the environment.
