In the wheel maintenance of self loading mixer, a few mixer drivers, in order to prevent the bolts and nuts on the wheel from rusting, apply lubricating oil on the bolts and nuts with ingenuity during installation. However, this practice is not only wrong, but also brings some hidden dangers to the driving safety of self loading mixer. After the bolt and nut are tightened, they are self-locking. However, the self-locking coefficient between them becomes smaller and the self-locking performance decreases after applying lubricating oil. When the self feeding mixer runs at high speed, the bolts and nuts are easy to loose or even fall off, which leads to the driving accident of the self feeding mixer.

不要用水沖洗車(chē)身

Do not flush the body with water

內(nèi)部夏天到了，常見(jiàn)私家車(chē)主們一邊用水沖洗車(chē)身，一邊用抹布擦拭，在此要提醒攪拌車(chē)司機(jī)的是：車(chē)身內(nèi)部不要用水直接沖洗。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、通孔非常多。用水沖洗后，要么沉積在凹槽內(nèi)不易干燥，要么從通孔處流到自動(dòng)上料攪拌車(chē)變速箱等部件上產(chǎn)生銹蝕。尤其是密封性能較好的自動(dòng)上料攪拌車(chē)更不能用水直接沖洗車(chē)身內(nèi)部。正確的方法是用濕抹布擦拭，但要避免積水。

When summer comes to the interior, it is common for private car owners to wash the car body with water while wiping it with a cloth. Here, we should remind the mixer driver that the interior of the car body should not be washed directly 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. 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 of automatic feeding mixer and other parts to produce corrosion. In particular, the automatic feeding mixer with good sealing performance can not directly wash the interior of the car body with water. The correct method is to use a wet cloth to wipe, but to avoid water.

不同品牌的冷 卻液不要混合使用

Do not mix different brands of coolant

誰(shuí)都知道自動(dòng)上料攪拌車(chē)發(fā)動(dòng)機(jī)冷 卻液不足時(shí)應(yīng)及時(shí)添加，但司機(jī)是否把不同品牌的冷 卻液溫在一起使用了呢?如果是，勸司機(jī)還是趁早把冷 卻液放掉，重新添加同一品牌的冷 卻液。因?yàn)椴煌放频睦?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)自動(dòng)上料攪拌車(chē)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。由于不同品牌的冷 卻液所用的防腐劑不同，所以不能混合使用。

Everyone knows that when the engine coolant of automatic feeding mixer is insufficient, it should be added in time, but does the driver use the coolant temperature of different brands together? If so, advise the driver to drain the coolant as soon as possible and add the same brand of coolant again. Because the chemical properties of different brands of coolant may vary greatly. For example, the preservative which is useful for ferrous metals often corrodes the aluminum products of automatic feeding mixer; However, the preservatives suitable for aluminum alloy are harmful to ferroalloy. As different brands of coolant use different preservatives, it can not be mixed.

電噴車(chē)啟動(dòng)時(shí)不要踩油門(mén)

Don't step on the accelerator when the EFI car starts

啟動(dòng)自動(dòng)上料攪拌車(chē)發(fā)動(dòng)機(jī)前踩幾腳油門(mén)，是許多駕駛員的習(xí)慣，尤其是在冬季冷車(chē)啟動(dòng)時(shí)。但這種啟動(dòng)方法卻不適用于電噴轎車(chē)。裝有電控噴油裝置的自動(dòng)上料攪拌車(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)發(fā)動(dòng)機(jī)的溫度、工況自動(dòng)調(diào)整供油量，使自動(dòng)上料攪拌車(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，自動(dòng)上料攪拌車(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，否則反而使自動(dòng)上料攪拌車(chē)發(fā)動(dòng)機(jī)啟動(dòng)不好。

It is a habit for many drivers to step on the accelerator before starting the engine of the automatic feeding mixer, especially when it is cold in winter. But this starting method is not suitable for EFI cars. The automatic feeding 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 engine, so that the automatic feeding mixer engine can start smoothly, that is, the fuel injection control device can automatically increase the fuel supply amount when the cold car starts. Therefore, there is no need to step on the accelerator when the automatic feeding mixer engine starts, let alone continuously step on it before starting, otherwise, the automatic feeding mixer engine will not start well.
