1.将车用尿素中加水
1. Add water to vehicle urea
有人说,我不使用农用尿素,加水总没有什么害处吧。这你就大错特错了,要知道水中也是含有杂质的,而这些杂质很容易形成固体物,从而导致柴油尾气处理液喷嘴堵塞,这对6方混凝土搅拌车SCR系统的伤害是不可逆转的!
Some people say that I don't use agricultural urea. There's no harm in adding water. This is a big mistake. You should know that the water also contains impurities, which are easy to form solids, resulting in the blockage of the nozzle of diesel tail gas treatment liquid, which will cause irreversible damage to the SCR system of 6-square concrete mixer!
2.认为劣质车用尿素便宜就行
2. Think inferior vehicle urea is cheap
很多司机为了省钱使用廉价的车用尿素,觉得无所谓,只要加了就行。通过代替去离子水,而使用普通水生产出的不合格车用尿素中含有很多超标的杂质,长期使用的话,会导致滤清器堵塞,降低SCR系统雾化效果,杂质过多甚会损坏尿素泵。
Many drivers use cheap car urea to save money. They think it doesn't matter. Just add it. The unqualified vehicle urea produced by using ordinary water instead of deionized water contains many excessive impurities. If used for a long time, the filter will be blocked, the atomization effect of SCR system will be reduced, and too many impurities will even damage the urea pump.
3.认为加车用尿素会增加油耗
3. It is considered that adding vehicle urea will increase fuel consumption
一些6方混凝土搅拌车使用者会通过屏蔽柴油尾气处理液来减少其油耗,从而缩减购买柴油尾气处理液的费用,以此来节省开支。这种认知是错误的,其实SCR系统是不参与搅拌车的传动和油的燃烧的,这样反而会促使SCR系统增加油耗。因为如果SCR系统出现故障,会导致发动机限扭,进而增加燃油量。
Some users of 6-square concrete mixer truck will reduce their fuel consumption by shielding diesel exhaust treatment liquid, so as to reduce the cost of purchasing diesel exhaust treatment liquid, so as to save expenses. This cognition is wrong. In fact, the SCR system does not participate in the transmission and oil combustion of the mixer, which will increase the fuel consumption of the SCR system. Because if the SCR system fails, it will cause the engine torque limit and increase the fuel volume.
4.认为车用尿素就是农用尿素
4. It is considered that vehicle urea is agricultural urea
很多人认为车用尿素和农用尿素是一样的,混着用是可以的,但是这种想法是错误的。因为车用尿素的配比是有严格要求的,一般是由32.5%高纯尿素和67.5%的去离子水组成,而农用尿素的颗粒物、金属离子、矿物质等杂质是非常多的。如果6方混凝土搅拌车使用农用尿素,经过SCR系统反应会产生一系列杂质,这对SCR系统会造成致命的损伤,其直接后果就是更换SCR后处理系统。
Many people think that vehicle urea and agricultural urea are the same, and it is possible to mix them, but this idea is wrong. Because there are strict requirements for the ratio of vehicle urea, which is generally composed of 32.5% high-purity urea and 67.5% deionized water, while there are many impurities such as particles, metal ions and minerals in agricultural urea. If agricultural urea is used in the 6m3 concrete mixer, a series of impurities will be generated through the SCR system reaction, which will cause fatal damage to the SCR system, and the direct consequence is to replace the SCR post-treatment system.
