如今看來(lái)，攪拌車的排放要達(dá)標(biāo)離不開(kāi)車用尿素，下面我們就來(lái)談一談攪拌車使用車用尿素的誤區(qū)有什么，了解充分才能讓好攪拌車的使用更加順利。
Now, it seems that the emission of the mixer truck can not reach the standard without the use of urea for driving. Now let's talk about the misunderstanding of the use of urea for the mixer truck. Only with a full understanding can we make the use of the mixer truck more safe and smooth.
認(rèn)為車用尿素是農(nóng)用尿素
It is considered that vehicle urea is agricultural urea
很多人認(rèn)為車用尿素和農(nóng)用尿素是一樣的，混用也可以，但這種想法是錯(cuò)誤的。由于車用尿素的配比要求嚴(yán)格，一般由32.5%的高純尿素和67.5%的去離子水組成，而農(nóng)用尿素則含有大量顆粒物、金屬離子、礦物質(zhì)等雜質(zhì)。如果混凝土攪拌車使用農(nóng)用尿素，SCR系統(tǒng)反應(yīng)后會(huì)產(chǎn)生一系列雜質(zhì)，對(duì)SCR系統(tǒng)造成致命傷害，直接后果就是更換SCR后處理系統(tǒng)。
Many people think that automotive urea and agricultural urea are the same, and it is OK to mix them, but this idea is wrong. Due to the strict requirements for the proportion of vehicle urea, it is generally composed of 32.5% high-purity urea and 67.5% deionized water, while agricultural urea contains a large number of particles, metal ions, minerals and other impurities. If the concrete mixer uses agricultural urea, a series of impurities will be generated after the SCR system reacts, causing fatal damage to the SCR system. The direct consequence is to replace the SCR post-treatment system.
車用尿素加水
Vehicle urea water
有人說(shuō)我不用農(nóng)用尿素，所以加水也沒(méi)壞處。這是一個(gè)大錯(cuò)誤。要知道，水中也含有雜質(zhì)，而這些雜質(zhì)很容易形成固體，從而導(dǎo)致柴油機(jī)尾氣處理液的噴嘴堵塞。對(duì)SCR系統(tǒng)的損害是不可逆的！
Some people say that I do not use agricultural urea, so adding water is not harmful. This is a big mistake. You should know that the water also contains impurities, which are easy to form solids, resulting in blockage of the nozzle of diesel engine exhaust treatment fluid. Damage to SCR system is irreversible!
認(rèn)為車用尿素會(huì)增加油耗
Thinks that vehicle urea will increase fuel consumption
部分?jǐn)嚢柢囉脩魰?huì)通過(guò)屏蔽柴油尾氣處理液來(lái)降低油耗，從而降低購(gòu)買柴油尾氣處理液的成本以節(jié)省資金。這種認(rèn)識(shí)是錯(cuò)誤的。事實(shí)上，SCR系統(tǒng)不參與攪拌車的傳動(dòng)和油的燃燒，反而會(huì)增加SCR系統(tǒng)的油耗。因?yàn)槿绻鸖CR系統(tǒng)出現(xiàn)故障，會(huì)導(dǎo)致發(fā)動(dòng)機(jī)扭矩限制，從而增加燃油量。
Some mixer truck users will reduce fuel consumption by shielding diesel exhaust treatment fluid, so as to reduce the cost of purchasing diesel exhaust treatment fluid and save money. This understanding is wrong. In fact, SCR system does not participate in the transmission of mixer truck and oil combustion, but will increase the oil consumption of SCR system. Because if the SCR system fails, the engine torque will be limited, which will increase the fuel volume.
認(rèn)為車用劣質(zhì)尿素便宜
Thinks inferior urea for vehicles is cheap
很多混凝土攪拌車司機(jī)為了省錢而用便宜的尿素車用，覺(jué)得沒(méi)關(guān)系，只要加了就行。通過(guò)更換去離子水，用普通水生產(chǎn)的不合格車用尿素含有大量超標(biāo)雜質(zhì)。長(zhǎng)期使用會(huì)造成過(guò)濾器堵塞，降低SCR系統(tǒng)的霧化效果，甚會(huì)因雜質(zhì)過(guò)多而損壞尿素泵。
Many concrete mixer drivers use cheap urea to save money. They think it doesn't matter. Just add it. Through the replacement of deionized water, the unqualified vehicle urea produced with ordinary water contains a large amount of excessive impurities. Long term use will cause filter blockage, reduce the atomization effect of SCR system, and even damage the urea pump due to excessive impurities.
相信大家對(duì)攪拌車使用車用尿素已經(jīng)有了更深的了解，希望這些知識(shí)能給大家?guī)?lái)更多的幫助。更多關(guān)于攪拌車設(shè)備的內(nèi)容您可以關(guān)注我們網(wǎng)站http://www.qirongguanjia.cn咨詢獲取到！
