In the wheel maintenance of self loading mixer truck, in order to prevent the bolts and nuts on the wheel from rusting, a few mixer truck drivers apply lubricating oil to the bolts and nuts during installation. However, this practice is not only wrong, but also brings certain hidden dangers to the driving safety of self loading mixer truck. After the bolt and nut are tightened, they have self-locking characteristics with each other. When the lubricant is applied, the self-locking coefficient between them becomes smaller and the self-locking performance decreases. When the self loading mixer truck runs at high speed, the bolts and nuts are easy to loosen or even fall off, resulting in a driving accident of the self loading mixer truck.

不要用水沖洗車身

Do not flush the body with water

內(nèi)部夏天到了，常見私家車主們一邊用水沖洗車身，一邊用抹布擦拭，在此要提醒攪拌車司機的是：車身內(nèi)部不要用水直接沖洗。因為駕駛室內(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上料攪拌車變速箱等部件上產(chǎn)生銹蝕。尤其是密封性能較好的自動上料攪拌車更不能用水直接沖洗車身內(nèi)部。正確的方法是用濕抹布擦拭，但要避免積水。

When summer comes, it is common for private car owners to wash the body with water and wipe it with a rag. Here, we should remind the mixer driver that the interior of the body should not be washed directly with water. Because the bottom of the floor rubber pad in the cab is not "flat", there are many grooves and through holes under the floor rubber pad in the cab due to structural needs. After washing with water, it either deposits in the groove and is not easy to dry, or flows from the through hole to the gearbox and other parts of the automatic feeding mixer to produce corrosion. In particular, the automatic feeding mixer with good sealing performance cannot directly flush the interior of the vehicle body with water. The correct method is to wipe with a wet rag, but avoid ponding.

不同品牌的冷卻液不要混合使用

Do not mix different brands of coolant

誰都知道自動上料攪拌車發(fā)動機冷卻液不足時應(yīng)及時添加，但司機是否把不同品牌的冷卻液溫在一起使用了呢?如果是，勸司機還是趁早把冷卻液放掉，重新添加同一品牌的冷卻液。因為不同品牌的冷卻液其化學(xué)性能可能相差懸殊，比如對黑色金屬有用的防腐劑，卻常常對自動上料攪拌車鋁制品有腐蝕作用;而適用于鋁臺金的防腐劑則對鐵合金有害。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 the automatic feeding mixer truck is insufficient, it should be added in time, but has the driver used the coolant temperature of different brands together? If so, advise the driver to drain the coolant as soon as possible and add the coolant of the same brand again. Because the chemical properties of different brands of coolants may vary greatly, such as preservatives useful for ferrous metals, but they often corrode the aluminum products of automatic feeding mixer trucks; The preservative suitable for aluminum Taijin is harmful to ferroalloy. Since different brands of coolant use different preservatives, they cannot be mixed.

電噴車啟動時不要踩油門

Do not step on the accelerator when starting the EFI vehicle

啟動自動上料攪拌車發(fā)動機前踩幾腳油門，是許多駕駛員的習(xí)慣，尤其是在冬季冷車啟動時。但這種啟動方法卻不適用于電噴轎車。裝有電控噴油裝置的自動上料攪拌車發(fā)動機與普通化油器式發(fā)動機不同，它的噴油控制裝置能根據(jù)發(fā)動機的溫度、工況自動調(diào)整供油量，使自動上料攪拌車發(fā)動機順利啟動，即在冷車啟動時，噴油控制裝置能自動增加供油量。所以，自動上料攪拌車發(fā)動機啟動時，沒有必要踩油門，更不要在啟動前連續(xù)急踩，否則反而使自動上料攪拌車發(fā)動機啟動不好。

It is the habit of many drivers to step on the accelerator before starting the engine of the automatic feeding mixer, especially when the vehicle is started cold in winter. However, this starting method is not suitable for EFI cars. The engine of the automatic feeding mixer equipped with the electronic control fuel injection device is different from the ordinary carburetor engine. Its fuel injection control device can automatically adjust the fuel supply according to the engine temperature and working conditions, so that the engine of the automatic feeding mixer can start smoothly, that is, when the cold vehicle starts, the fuel injection control device can automatically increase the fuel supply. Therefore, it is not necessary to step on the accelerator when starting the engine of the automatic feeding mixer, let alone continuously step on it before starting, otherwise the engine of the automatic feeding mixer will not start well.
