攪拌車車用尿素誤區(qū)你犯了多少？
車用尿素就是柴油車尾氣處理液，主要用于吸收柴油車尾氣中的氮氧化物，在攪拌車、隨車吊中十分常見。關(guān)于車用尿素經(jīng)常存在一些認知誤區(qū)。
Vehicle urea is diesel vehicle exhaust treatment fluid, mainly used to absorb nitrogen oxides in diesel vehicle exhaust, which is very common in mixer and truck mounted crane. There are some misunderstandings about vehicle urea.
誤區(qū)一：車用尿素就是農(nóng)用尿素
Error 1: Vehicle urea is agricultural urea
很多人認為車用尿素和農(nóng)用尿素是一樣的，混著用是可以的，這種想法是錯誤的，車用尿素的配比是有嚴格要求的，一般是由高純尿素和去離子的水組成，而農(nóng)用尿素的顆粒物、金屬離子、礦物質(zhì)等雜質(zhì)非常多，如果混凝土攪拌車使用農(nóng)用尿素，經(jīng)過系統(tǒng)反應(yīng)一系列雜質(zhì)，會對統(tǒng)造成致命的損傷，直接后果就是更換后處理系統(tǒng)，那就得不償失了。
Many people think that vehicle urea and agricultural urea are the same and can be mixed. This idea is wrong. There are strict requirements for the proportion of vehicle urea, which is generally composed of high-purity urea and deionized water. There are many impurities in agricultural urea, such as particles, metal ions and minerals. If agricultural urea is used in concrete mixer, it will undergo a series of reactions Impurities will cause fatal damage to the system, and the direct consequence is to replace the post-processing system, which is not worth the loss.
誤區(qū)二：柴油尾氣處理液加水
Mistake 2: adding water to diesel tail gas treatment solution
有人說，我不使用農(nóng)用尿素，加水總沒有什么害處吧，這你就大錯特錯了，要知道水中也是含有雜質(zhì)的，而這些雜質(zhì)很容易形成固體物，從而導(dǎo)致尾氣處理液噴嘴堵塞，這對系統(tǒng)的傷害是不可逆轉(zhuǎn)的。
Some people say that if I don't use agricultural urea, there is no harm in adding water. You are very wrong. You should know that there are impurities in the water, and these impurities are easy to form solids, which will cause the nozzle of tail gas treatment liquid to be blocked. The damage to the system is irreversible.
誤區(qū)三：加柴油尾氣處理液會增加油耗
Mistake 3: adding diesel exhaust treatment fluid will increase fuel consumption
一些專用車使用者會通過屏蔽柴油尾氣處理液來減少其油耗，從而縮減購買柴油尾氣處理液的費用，以此來節(jié)省開支。這種認知是錯誤的，其實系統(tǒng)是不參與混凝土攪拌車的傳動和油的燃燒的，反而會促使系統(tǒng)增加油耗是因為系統(tǒng)出現(xiàn)故障，從而導(dǎo)致發(fā)動機限扭，進而增加了燃油量。
Some special vehicle users will reduce their fuel consumption by shielding diesel exhaust treatment fluid, so as to reduce the cost of purchasing diesel exhaust treatment fluid, so as to save money. This kind of cognition is wrong. In fact, the system does not participate in the transmission and oil combustion of the concrete mixer truck. On the contrary, it will increase the fuel consumption of the system because of the system failure, which leads to the engine torque limit and thus increases the fuel consumption.
誤區(qū)四：劣質(zhì)柴油尾氣處理液實惠無害
Misunderstanding 4: low quality diesel exhaust treatment fluid is affordable and harmless
柴油尾氣處理液本身不高，劣質(zhì)的之間的差別不大，很多司機為了省錢使用廉價的柴油尾氣處理液，覺得無所謂，有加就行。代替去離子水而使用普通水生產(chǎn)出的不合格柴油尾氣處理液中含有很多超標的雜質(zhì)，長期使用，會導(dǎo)致濾清器堵塞，柴油尾氣處理液輸送管道和噴嘴，降低系統(tǒng)霧化效果，雜質(zhì)過多甚會損壞尿素泵。
The price of diesel exhaust treatment fluid itself is not high, and there is little difference between inferior ones. In order to save money, many drivers use cheap diesel exhaust treatment fluid, and feel that it doesn't matter. Just add it. The unqualified diesel tail gas treatment liquid produced by using ordinary water instead of deionized water contains a lot of excessive impurities. Long term use will lead to filter blockage, pipeline and nozzle of diesel tail gas treatment liquid, reduce the atomization effect of the system, and excessive impurities will even damage the urea pump.
