水泥自上料攪拌車尿素結(jié)晶什么原因?

來(lái)源:http://m.top2010.cn/ 日期:2023-01-13 發(fā)布人:admin
水泥自上料攪拌車的車用尿素結(jié)晶問(wèn)題一直是朋友們的困擾,它為什么會(huì)結(jié)晶呢?下面小編來(lái)
The problem of urea crystallization for cement self-feeding mixer truck has always been a problem for friends. Why does it crystallize? Let's make up
原因一:使用了劣質(zhì)尿素
Cause 1: use of inferior urea
現(xiàn)在市面上的車用尿素質(zhì)量參差不齊,一些無(wú)良商家為了以低價(jià)來(lái)吸引顧客,用農(nóng)用尿素或者工業(yè)尿素為原料代替專用高純度車用尿素原料生產(chǎn)車用尿素溶液。而一些朋友為了省錢,購(gòu)買這種劣質(zhì)尿素,長(zhǎng)期使用,對(duì)車輛的后處理系統(tǒng)有很大的損害,后期的維修成本更高,得不償失。
At present, the quality of vehicle urea on the market is uneven. In order to attract customers at a low price, some unscrupulous businesses use agricultural urea or industrial urea as raw materials to produce vehicle urea solution instead of special high-purity vehicle urea raw materials. In order to save money, some friends bought this kind of inferior urea and used it for a long time, which would cause great damage to the after-treatment system of the vehicle. The later maintenance costs would be higher, and the gains outweigh the losses.
原因二:尿素溶液不純
Cause 2: the urea solution is not pure
車用尿素液的純凈度是區(qū)分尿素液質(zhì)量?jī)?yōu)劣的重要指標(biāo)。車用尿素溶液雖然看著是透明的液體,但里面含有很多的不溶物,比如縮二脲、縮三脲等,如果這些膠體物質(zhì)含量過(guò)高,會(huì)產(chǎn)生氰尿酸結(jié)晶。
The purity of vehicle urea solution is an important indicator to distinguish the quality of urea solution. Although the vehicle urea solution looks like a transparent liquid, it contains many insoluble substances, such as biuret and biuret. If the content of these colloidal substances is too high, cyanuric acid crystals will be produced.
原因三:用車習(xí)慣不良
Cause 3: bad use habits

很多朋友在用車時(shí),對(duì)SCR后系統(tǒng)的維護(hù)和保養(yǎng)不到位,所以建議大家:
Many friends do not maintain the SCR system properly when using the car, so we recommend that you:
定期更換尿素濾芯,氣驅(qū)尿素泵、空氣輔助式尿素泵以及空氣濾芯;尿素罐內(nèi)部容易積累雜質(zhì)沉淀物和結(jié)晶,所以要定期清洗,同時(shí)尿素罐外部也要注意清潔,尤其是罐蓋子周圍,加注尿素時(shí)別讓贓物掉進(jìn)罐里;
Regularly replace the urea filter element, air-driven urea pump, air-assisted urea pump and air filter element; It is easy to accumulate impurities, precipitates and crystals inside the urea tank, so it is necessary to clean it regularly. At the same time, pay attention to cleaning the outside of the urea tank, especially around the tank cover. When adding urea, do not let the dirt fall into the tank;
尿素噴嘴、管路等也會(huì)出現(xiàn)結(jié)晶堵塞的現(xiàn)象,建議用戶根據(jù)廠家建議到服務(wù)站作保養(yǎng)、檢查和維護(hù);熄火后切忌立刻斷開(kāi)整車電源。
Crystallization blockage may also occur in urea nozzles, pipelines, etc. Users are recommended to go to the service station for maintenance, inspection and maintenance according to the manufacturer's recommendations; Do not disconnect the power supply of the whole vehicle immediately after flameout.
后處理系統(tǒng)的吹掃過(guò)程,會(huì)在發(fā)動(dòng)機(jī)熄火后進(jìn)行。壓縮空氣吹掃管路,目的是排除管路中的尿素,避免結(jié)晶堵塞,整個(gè)吹掃過(guò)程大概持續(xù)30-120秒。所以建議當(dāng)車輛鑰匙開(kāi)關(guān)關(guān)閉兩分鐘后再切斷整車電源。
The purging process of the aftertreatment system will be carried out after the engine stops. The purpose of compressed air purging the pipeline is to eliminate the urea in the pipeline and avoid crystal blockage. The whole purging process lasts about 30-120 seconds. Therefore, it is recommended to cut off the power supply of the whole vehicle after the vehicle key switch is turned off for two minutes.
綜上所述,想要防止車用尿素結(jié)晶,定期對(duì)SCR系統(tǒng)進(jìn)行清洗養(yǎng)護(hù)和選用靠譜的車用尿素顯得尤為重要!更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://m.top2010.cn咨詢!
To sum up, in order to prevent the crystallization of vehicle urea, it is particularly important to regularly clean and maintain the SCR system and select reliable vehicle urea! Come to our website for more relevant content http://m.top2010.cn consulting service
