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.

检查中冷器是否损坏，用同样的方法按压气泵，仔细检查自上料平口搅拌车水箱前中冷器是否漏气，调整阀门，并定期找人员根据车辆值调整阀门间隙。

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.

更换合格的尿素和选用车用尿素，须购买合格的产品，不要轻易更换尿素喷嘴。有的自上料平口搅拌车司机为了省钱，故意用石头改装尿素喷嘴，有的自上料平口搅拌车司机甚加水，有的自上料平口搅拌车司机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.

操作前检查项目

Inspection items before operation

平口搅拌车空气系统运行前检查润滑油油位，保持油位在油尺上下线之间，接近下及时提高油位线。,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.

添加润滑油的注意事项

Precautions for adding lubricating oil

①加油时，应无压力进行。作业前应将平口搅拌车周围的灰尘等杂物清理干净，以免进入注油器。

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注油器内的润滑油为普通柴油机油，可使用粘度为2.5-7度的润滑油或工业40#油。储油杯中的油应及时更换。储油杯容量以100ml计算，使用100小时为宜。

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.

维护

maintain

定期清洗空气平口搅拌车的滤芯。由于滤芯太脏，进入压缩机气缸的空气中含有过多的灰尘，会加速气缸和活塞环的磨损，容易形成积碳，影响气阀的密封性能；会造成拉缸和窜气，造成润滑油污染，影响润滑效果；当气体被窜气时，也会出现油污现象。如果气缸壁与活塞环之间的间隙过大，受污染的润滑油就会进入压缩室。并形成油雾，污染压缩空气。

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.
