自动上料搅拌车容易被忽视的常识性错误

概述:在自上料搅拌车的车轮维修中,少数搅拌车司机为了防止车轮上螺栓螺母生锈,安装时别出心裁地将螺栓螺母都涂上润滑油,殊不知这种做法不仅错误,而且给自上料搅拌车行车安 全带来一定
在自上料搅拌车的车轮维修中,少数搅拌车司机为了防止车轮上螺栓螺母生锈,安装时别出心裁地将螺栓螺母都涂上润滑油,殊不知这种做法不仅错误,而且给自上料搅拌车行车安 全带来一定的隐患。螺栓和螺母拧紧后,相互间具有自锁的特性。而涂上润滑油后,二者之间的自锁系数变小、自锁性能下降。在自上料搅拌车高速行驶时,螺栓螺母很容易松动乃脱落,从而引发自上料搅拌车行车事故。
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.
不要用水冲洗车身
Do not flush the body with water
内部夏天到了,常见私家车主们一边用水冲洗车身,一边用抹布擦拭,在此要提醒搅拌车司机的是:车身内部不要用水直接冲洗。因为驾驶室内地板胶垫的下面可不是“一马平川”,结构上的需要使驾驶室地板胶垫下面的凹槽、通孔非常多。用水冲洗后,要么沉积在凹槽内不易干燥,要么从通孔处流到自动上料搅拌车变速箱等部件上产生锈蚀。尤其是密封性能较好的自动上料搅拌车更不能用水直接冲洗车身内部。正确的方法是用湿抹布擦拭,但要避免积水。
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.
不同企业的冷 却液不要混合使用
Do not mix different brands of coolant
谁都知道自动上料搅拌车发动机冷 却液不足时应及时添加,但司机是否把不同企业的冷 却液温在一起使用了呢?如果是,劝司机还是趁早把冷 却液放掉,重新添加同一企业的冷 却液。因为不同企业的冷 却液其化学性能可能相差悬殊,比如对黑色金属有 用的防腐剂,却常常对自动上料搅拌车铝制品有腐蚀作用;而适用于铝台金的防腐剂则对铁合金有害。由于不同企业的冷 却液所用的防腐剂不同,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.
电喷车启动时不要踩油门
Don't step on the accelerator when the EFI car starts
启动自动上料搅拌车发动机前踩几脚油门,是许多驾驶员的习惯,尤其是在冬季冷车启动时。但这种启动方法却不适用于电喷轿车。装有电控喷油装置的自动上料搅拌车发动机与普通化油器式发动机不同,它的喷油控制装置能根据发动机的温度、工况自动调整供油量,使自动上料搅拌车发动机顺利启动,即在冷车启动时,喷油控制装置能自动增加供油量。所以,自动上料搅拌车发动机启动时,没有必要踩油门,更不要在启动前连续急踩,否则反而使自动上料搅拌车发动机启动不好。
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.
