1. You should know that the urea used for loading is for diesel vehicles, and most mixer vehicles use diesel engines. Because diesel will emit harmful gas nitrogen oxides, which will cause environmental pollution. Long term inhalation of this waste gas will cause great harm to human body. In order to reduce this hazard, truck urea should be added to the mixer truck with diesel engine. The addition of vehicle urea has a catalytic effect. Chemical reaction occurs to convert nitrogen oxides into nitrogen and water to be discharged.

2、自動(dòng)上料攪拌車排放達(dá)標(biāo)離不開車用尿素。車用尿素是一種柴油車尾氣處理液。車用尿素主要用于吸收柴油車尾氣中的氮氧化物，也是SCR工作過程中的關(guān)鍵環(huán)節(jié)。

2. Urea for start-up is indispensable for the automatic feeding mixer to reach the emission standard. Vehicle urea is a kind of diesel vehicle exhaust treatment fluid. Vehicle urea is mainly used to absorb nitrogen oxides in diesel vehicle exhaust, and it is also a key link in the working process of SCR.

3、車用尿素對車輛的動(dòng)力和油耗起著關(guān)鍵作用。如果不給車加尿素，或者使用純度不夠、質(zhì)量差的尿素溶液，都會導(dǎo)致發(fā)動(dòng)機(jī)自動(dòng)減速。同時(shí)，劣質(zhì)車用尿素會污染SCR催化反應(yīng)罐中的催化劑，造成后處理系統(tǒng)部件的損壞。您知道，后處理系統(tǒng)的維護(hù)成本可能相當(dāng)昂貴。這種做法不僅增加了對環(huán)境的破壞，也增加了攪拌車的使用成本。

3. Vehicle urea plays a key role in vehicle power and fuel consumption. If urea is not added to the vehicle, or urea solution with insufficient purity and poor quality is used, the engine will slow down automatically. At the same time, inferior automotive urea will pollute the catalyst in the SCR catalytic reaction tank and cause damage to the components of the aftertreatment system. As you know, the maintenance cost of the aftertreatment system can be quite expensive. This practice not only increases the damage to the environment, but also increases the use cost of the mixer.

攪拌車使用尿素的誤區(qū)

Misunderstanding of using urea in mixer truck

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)后會產(chǎn)生一系列雜質(zhì)，對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.

有人說我不用農(nóng)用尿素，所以加水也沒壞處。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!

部分自動(dòng)上料攪拌車用戶會通過屏蔽柴油尾氣處理液來降低油耗，從而降低購買柴油尾氣處理液的成本以節(jié)省資金。這種認(rèn)識是錯(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，反而會增加SCR系統(tǒng)的油耗。因?yàn)槿绻鸖CR系統(tǒng)出現(xiàn)故障，會導(dǎo)致發(fā)動(dòng)機(jī)扭矩限制，從而增加燃油量。

Some users of automatic loading mixer will reduce fuel consumption by shielding diesel exhaust treatment liquid, so as to reduce the cost of purchasing diesel exhaust treatment liquid 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.

很多司機(jī)為了省錢而用便宜的尿素車用，覺得沒關(guān)系，只要加了就行。通過更換去離子水，用普通水生產(chǎn)的不合格車用尿素含有很多超標(biāo)雜質(zhì)。長期使用會造成過濾器堵塞，降低SCR系統(tǒng)的霧化效果，甚會因雜質(zhì)過多而損壞尿素。泵。

Many drivers use cheap urea to save money. They think it doesn't matter. Just add it. By replacing deionized water, the unqualified vehicle urea produced with ordinary water contains many excessive impurities. Long term use will cause filter blockage, reduce the atomization effect of SCR system, and even damage urea due to excessive impurities. Pump.
