The turbocharger is damaged. If the impeller shaft of the supercharger is moved, it is basically determined that the oil in the tank has been damaged. In addition, check the pipeline, press the air pump with foam water to check the booster rubber and outlet pipe, and check the belt buckle for air leakage.

檢查中冷器是否損壞，用同樣的方法按壓氣泵，仔細(xì)檢查自上料平口攪拌車水箱前中冷器是否漏氣，調(diào)整閥門，并定期找人員根據(jù)車輛公里值調(diào)整閥門間隙。

Check whether the intercooler is damaged, press the air pump using the same method, carefully check whether the intercooler in front of the water tank of the self feeding flat mouth mixer has air leakage, adjust the valve, and regularly seek professional personnel to adjust the valve clearance according to the vehicle mileage.

更換合格的尿素和選用車用尿素，須購(gòu)買合格的產(chǎn)品，不要輕易更換尿素噴嘴。有的自上料平口攪拌車司機(jī)為了省錢，故意用石頭改裝尿素噴嘴，有的自上料平口攪拌車司機(jī)甚至加水，有的自上料平口攪拌車司機(jī)直接拔出塞子而不用尿素。

To replace qualified urea and select vehicle urea, it is necessary to purchase qualified products, and do not easily replace the urea nozzle. Some drivers of self loading flat mouth mixer trucks intentionally use stones to modify the urea nozzle in order to save money, some drivers of self loading flat mouth mixer trucks even add water, and some drivers of self loading flat mouth mixer trucks directly pull out the plug without using urea.

操作前檢查項(xiàng)目

Inspection items before operation

平口攪拌車空氣系統(tǒng)運(yùn)行前檢查潤(rùn)滑油油位，保持油位在油尺上下線之間，接近下及時(shí)提高油位線。,油杯口密封圈完好。

Before operation of the air system of the flat mouth mixer truck, check the lubricating oil level, keep the oil level between the upper and lower lines of the dipstick, and promptly raise the oil level line when it approaches the lower limit., The sealing ring of the oil cup port is intact.

添加潤(rùn)滑油的注意事項(xiàng)

Precautions for adding lubricating oil

①加油時(shí)，應(yīng)無(wú)壓力進(jìn)行。作業(yè)前應(yīng)將平口攪拌車周圍的灰塵等雜物清理干凈，以免進(jìn)入注油器。

① When refueling, it should be done without pressure. Before operation, dust and other debris around the flat mouth mixer should be cleaned to avoid entering the oil injector.

②注油器內(nèi)的潤(rùn)滑油為普通柴油機(jī)油，可使用粘度為2.5-7度的潤(rùn)滑油或工業(yè)40#油。儲(chǔ)油杯中的油應(yīng)及時(shí)更換。儲(chǔ)油杯容量以100ml計(jì)算，使用100小時(shí)為宜。

② The lubricating oil in the injector is ordinary diesel engine oil, and lubricating oil with a viscosity of 2.5-7 degrees or industrial 40 # oil can be used. The oil in the oil storage cup should be replaced in a timely manner. The capacity of the oil storage cup is calculated as 100ml, and it is appropriate to use it for 100 hours.

維護(hù)

maintain

定期清洗空氣平口攪拌車的濾芯。由于濾芯太臟，進(jìn)入壓縮機(jī)氣缸的空氣中含有過(guò)多的灰塵，會(huì)加速氣缸和活塞環(huán)的磨損，容易形成積碳，影響氣閥的密封性能；會(huì)造成拉缸和竄氣，造成潤(rùn)滑油污染，影響潤(rùn)滑效果；當(dāng)氣體被竄氣時(shí)，也會(huì)出現(xiàn)油污現(xiàn)象。如果氣缸壁與活塞環(huán)之間的間隙過(guò)大，受污染的潤(rùn)滑油就會(huì)進(jìn)入壓縮室。并形成油霧，污染壓縮空氣。

Regularly clean the filter element of the air flat mixer truck. Due to the dirty filter element, the air entering the compressor cylinder contains too much dust, which can accelerate the wear of the cylinder and piston ring, easily forming carbon deposits, and affecting the sealing performance of the gas valve; It can cause cylinder pulling and blowby, causing lubricating oil pollution, and affecting the lubrication effect; When gas is blown away, oil contamination can also occur. If the gap between the cylinder wall and the piston ring is too large, contaminated lubricating oil can enter the compression chamber. And forms an oil mist that contaminates the compressed air.
