There are many places that are easy to be ignored in the maintenance of automatic feeding mixer. Let's take a look at the aspects below.

一、二者之間的自鎖系數(shù)變小、自鎖性能下降。在攪拌車(chē)高速行駛時(shí)，螺栓螺母很容易松動(dòng)乃至脫落，從而引發(fā)行車(chē)事故。不要用水沖洗車(chē)身，因?yàn)橄奶鞖鉁馗?，很多司機(jī)選擇用水沖洗車(chē)身，在拿干凈的抹布擦拭，但其實(shí)車(chē)身內(nèi)部是不能用水來(lái)沖洗的。因?yàn)轳{駛室內(nèi)地板膠墊的下面可不是“一馬平川”，結(jié)構(gòu)上的需要使駕駛室地板膠墊下面的凹槽、通孔很多。

1、 The self-locking coefficient becomes smaller and the self-locking performance decreases. When the mixer is running at high speed, the bolts and nuts are easy to loose or even fall off, which leads to traffic accidents. Don't wash the car body with water. Because of the high temperature in summer, many drivers choose to wash the car body with water and wipe it with a clean cloth. However, the interior of the car body can't be washed with water. Because the bottom of the floor mat in the cab is not flat, there are many grooves and through holes under the floor mat in the cab due to the need of structure.

用水沖洗后，要么沉積在凹槽內(nèi)不易干燥，要么從通孔處流到變速箱等部件上產(chǎn)生銹蝕。尤其是密封性能較好的轎車(chē)不能用水直接沖洗車(chē)身內(nèi)部。

After washing with water, either it is deposited in the groove and not easy to dry, or it flows from the through hole to the gearbox and other parts to produce corrosion. Especially for cars with good sealing performance, the interior of the car body cannot be washed directly with water.

正確的方法是用濕抹布擦拭，但要避免積水。不同的冷卻液不要混合使用不同的冷卻液其化學(xué)性能可能相差懸殊，比如對(duì)黑色金屬有用的防腐劑，卻常常對(duì)鋁制品有腐蝕作用;而適用于鋁臺(tái)金的防腐劑則對(duì)鐵合金有害。由于不同的冷卻液所用的防腐劑不同，所以不能混合使用。

The correct method is to use a wet cloth to wipe, but to avoid water. Do not mix different coolants. The chemical properties of different coolants may vary greatly. For example, preservatives are useful for ferrous metals, but they often corrode aluminum products; However, the preservatives suitable for aluminum alloy are harmful to ferroalloy. Due to the different preservatives used in different coolant, it can not be mixed.

二、啟動(dòng)時(shí)不要踩油門(mén)：?jiǎn)?dòng)攪拌車(chē)發(fā)動(dòng)機(jī)前踩幾腳油門(mén)，是許多攪拌車(chē)駕駛員的習(xí)慣，尤其是在冬季冷車(chē)啟動(dòng)時(shí)。裝有電控噴油裝置的攪拌車(chē)發(fā)動(dòng)機(jī)與普通化油器式發(fā)動(dòng)機(jī)不同，它的噴油控制裝置能根據(jù)攪拌車(chē)發(fā)動(dòng)機(jī)的溫度、工況自動(dòng)調(diào)整供油量，使攪拌車(chē)發(fā)動(dòng)機(jī)順利啟動(dòng)，即在冷車(chē)啟動(dòng)時(shí)，噴油控制裝置能自動(dòng)增加供油量。所以，攪拌車(chē)發(fā)動(dòng)機(jī)啟動(dòng)時(shí)，沒(méi)有必要踩油門(mén)，更不要在啟動(dòng)前連續(xù)急踩，否則反而使攪拌車(chē)發(fā)動(dòng)機(jī)啟動(dòng)不好。

2、 Don't step on the accelerator when starting: it's the habit of many mixer drivers to step on the accelerator before starting the mixer engine, especially when it's cold in winter. The mixer engine equipped with electronic control fuel injection device is different from the ordinary carburetor engine. Its fuel injection control device can automatically adjust the fuel supply amount according to the temperature and working condition of the mixer engine, so that the mixer engine can start smoothly. That is to say, the fuel injection control device can automatically increase the fuel supply amount during the cold start. Therefore, there is no need to step on the accelerator when the mixer engine starts, let alone continuously step on it before starting, otherwise, the mixer engine will not start well.

三、不要給自動(dòng)上料攪拌車(chē)的輪胎螺栓螺母涂油在車(chē)輪維修中，少數(shù)司機(jī)為了防止攪拌車(chē)的車(chē)輪上螺栓螺母生銹，安裝時(shí)別出心裁地將螺栓螺母都涂上潤(rùn)滑油，殊不知這種做法不僅錯(cuò)誤，而且給攪拌車(chē)行車(chē)安全帶來(lái)的隱患。螺栓和螺母擰緊后，相互間具有自鎖的特性。

3、 Don't oil the wheel bolts and nuts of the automatic feeding mixer. In wheel maintenance, in order to prevent the wheel bolts and nuts of the mixer from rusting, a few drivers apply lubricating oil on the bolts and nuts with ingenuity during installation. However, this practice is not only wrong, but also brings hidden danger to the driving safety of the mixer. After the bolt and nut are tightened, they are self-locking.
