全自動(dòng)攪拌車(chē)多使用在工程建筑中，為我們的現(xiàn)代化建設(shè)作出了重大貢獻(xiàn)，攪拌車(chē)屬于專用車(chē)的一種，很多的攪拌車(chē)都出自“專汽之都”湖北隨州，它是由專用車(chē)底盤(pán)和上裝組成的，雖然是專用車(chē)，但是它跟其它車(chē)輛一樣也會(huì)偶爾出現(xiàn)故障，那么攪拌車(chē)一般會(huì)出現(xiàn)哪些故障呢？
Fully automatic mixer trucks are commonly used in engineering and construction, making significant contributions to our modernization construction. Mixers are a type of specialized vehicle, and many of them come from Suizhou, Hubei, the "capital of specialized automobiles". They are composed of a specialized vehicle chassis and upper body. Although they are specialized vehicles, they also occasionally malfunction like other vehicles. So what are the common faults of mixer trucks?
對(duì)于全自動(dòng)攪拌車(chē)出現(xiàn)的故障，我們首先必須要了解故障出現(xiàn)的性質(zhì)，結(jié)合攪拌車(chē)的車(chē)齡，這個(gè)故障是持續(xù)很長(zhǎng)時(shí)間了還是突然出現(xiàn)的；空車(chē)和重載時(shí)故障是否依然存在；轉(zhuǎn)速不同時(shí)故障有沒(méi)有差別，以上這些因素都是要考慮的。
For the malfunction of a fully automatic mixer truck, we must first understand the nature of the malfunction, and based on the age of the mixer truck, whether the malfunction has persisted for a long time or suddenly appeared; Whether the fault still exists when the vehicle is empty or overloaded; Whether there are differences in faults when the speed is different, all of these factors need to be considered.
要知道攪拌車(chē)的罐體重心是在軸線上，正常狀態(tài)下罐體的運(yùn)行是平穩(wěn)的，但是如果積料或者運(yùn)轉(zhuǎn)不均勻，就會(huì)導(dǎo)致罐體重心偏移，罐體在運(yùn)行中就會(huì)出現(xiàn)抖動(dòng)，那么積料造成的抖動(dòng)故障表現(xiàn)在以下兩個(gè)方面：
It should be noted that the center of gravity of the tank body of the mixer truck is on the axis, and under normal conditions, the operation of the tank body is stable. However, if there is material accumulation or uneven operation, it will cause the center of gravity of the tank body to shift, and the tank body will shake during operation. The shaking fault caused by material accumulation is manifested in the following two aspects:
1.罐體抖動(dòng)呈現(xiàn)周期性變化，2.罐體轉(zhuǎn)動(dòng)抖動(dòng)沒(méi)有規(guī)律，此時(shí)檢查油箱油液是否渾濁，減速機(jī)是否有損壞導(dǎo)致油液混入金屬顆粒。
1. The shaking of the tank body shows periodic changes, and 2. The shaking of the tank body is irregular. At this time, check whether the oil in the tank is turbid, and whether there is damage to the gearbox that has caused the oil to mix with metal particles.
故障具體分析：
Specific fault analysis:
液壓系統(tǒng)本身在輸出功率時(shí)是有聲音的，尤其是在大功率輸出時(shí)，所以如果空車(chē)就有大功率輸出的規(guī)律性噪音時(shí)，應(yīng)排除是罐體積料方面的原因，在重載時(shí)，如果負(fù)載過(guò)大超出系統(tǒng)溢流閥的設(shè)定值，系統(tǒng)就會(huì)溢流，此時(shí)液壓系統(tǒng)就會(huì)產(chǎn)生急劇的嘯叫聲，同時(shí)油溫會(huì)快速升高，一般機(jī)械原因的噪音會(huì)隨著發(fā)動(dòng)機(jī)的轉(zhuǎn)速提高而產(chǎn)生。
The hydraulic system itself produces sound when outputting power, especially during high-power output. Therefore, if there is regular noise from high-power output when the vehicle is empty, it should be ruled out that it is due to the accumulation of material in the tank body. During heavy loads, if the load exceeds the set value of the system overflow valve, the system will overflow, and at this time, the hydraulic system will produce a sharp howling sound, while the oil temperature will quickly rise, Generally, mechanical noise can occur as the engine speed increases.
如果攪拌車(chē)出現(xiàn)重載時(shí)無(wú)力的情況，此時(shí)應(yīng)拆開(kāi)濾芯檢查，如果在濾芯內(nèi)發(fā)現(xiàn)金屬粉末、銅沫甚至大塊金屬物，即可斷定是液壓泵或馬達(dá)磨損。
If the mixer truck becomes weak during heavy loading, the filter element should be disassembled for inspection. If metal powder, copper foam, or even large metal objects are found inside the filter element, it can be concluded that the hydraulic pump or motor is worn.
其實(shí)很多的攪拌車(chē)故障在駕駛室內(nèi)部的儀表盤(pán)上也是可以看出來(lái)的，大家只要在平時(shí)多加注意，及早的發(fā)現(xiàn)故障并處理，就不會(huì)因故障而耽誤攪拌車(chē)作業(yè)。您有需求就來(lái)我們網(wǎng)站http://www.mothernature2u.com咨詢吧！
In fact, many mixer truck faults can also be seen on the dashboard inside the driver's cab. As long as everyone pays more attention in daily life, discovers and handles faults early, they will not delay the mixer truck operation due to faults.
