有些司机总说上坡很没劲，油耗还很高。如果搅拌机定期更换机油、机油滤清器、柴油滤清器和空气滤清器，应该是有几个问题：
Some drivers always say that uphill driving is boring and fuel consumption is high. If the mixer regularly changes the oil, oil filter, diesel filter and air filter, there should be several problems:
涡轮增压器损坏。如果移动增压器的叶轮轴，则基本确定油箱中的油已损坏。此外，还应检查管路，用泡沫水按压气泵检查增压器橡胶和出口管。检查皮带扣是否漏气。
The turbocharger is damaged. If the impeller shaft of the supercharger is moved, it is basically certain that the oil in the oil tank has been damaged. In addition, check the pipeline, press the air pump with foam water to check the supercharger rubber and outlet pipe. 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 in the same way, carefully check whether the intercooler in front of the water tank leaks, adjust the valve, and regularly find a professional to adjust the valve clearance according to the vehicle kilometer value.
更换合格的尿素和选用车用尿素，必须购买合格的产品，不要轻易更换尿素喷嘴。有的搅拌车司机为了省钱，故意用石头改装尿素喷嘴，有的搅拌车司机甚加水，有的搅拌车司机直接拔出塞子而不用尿素。
To replace qualified urea and select vehicle urea, qualified products must be purchased. Do not easily replace the urea nozzle. In order to save money, some mixer truck drivers deliberately refit urea nozzles with stones. Some mixer truck drivers even add water. Some mixer truck drivers directly pull out plugs without urea.
校准喷油器。不要轻易加便宜的柴油。如果喷油器损坏，节省下来的钱不足以让你更换喷油嘴。
Calibrate the fuel injectors. Do not add cheap diesel easily. If the fuel injector is damaged, the money saved will not be enough for you to replace the fuel injector.
前挡推不到位，后挡拉不到底。有很多车辆严重挂档，而且往往不到位。这种情况一般有以下原因：变速杆或球头磨损，从齿轮下部到齿轮箱上部有许多球头。由于正常行驶时需要不断换挡，球头容易磨损，发现有变化时需及时更换；变速杆拉索目前，大量专用车采用了变速器拉索的设计，长时间使用会产生长刺，使换档困难甚无法换档。
The front block is not pushed in place, and the rear block is not pulled to the bottom. There are a lot of vehicles that are seriously engaged and often not in place. This situation is generally caused by the following reasons: the gear lever or ball joint is worn, and there are many ball joints from the lower part of the gear to the upper part of the gearbox. The ball joint is easily worn due to constant gear shifting during normal driving, so it needs to be replaced in time in case of any change; At present, a large number of special vehicles adopt the design of transmission cable, which will produce long thorns after long-term use, making it difficult or even impossible to shift gears.
如果发现拉索问题，应及时更换；如果选择了变速杆底座螺钉，无论变速杆位于驾驶室还是发动机上都会有固定螺钉，如果底座松动，换档困难；如果变速杆底座松动，上盖端盖花键套或花键轴的严重磨损也将直接导致齿轮啮合困难甚失效。
If any cable problem is found, it shall be replaced in time; If the shift lever base screw is selected, whether the shift lever is located in the cab or on the engine, there will be fixed screws. If the base is loose, it will be difficult to shift; If the shift lever base is loose, the severe wear of the upper cover end cover spline sleeve or spline shaft will directly lead to difficult gear engagement or even failure.
检查电磁阀。如果小盖开关电磁阀的顶针损坏，也会导致换档困难。虽然混凝土搅拌车的车身很重，但只要你掌握了驾驶方法，对变速箱有足够的了解，就永远不会有困难。
Check the solenoid valve. If the ejector pin of the small cover switch solenoid valve is damaged, it will also lead to difficult shifting. Although the body of the concrete mixer is very heavy, as long as you master the driving method and have enough knowledge of the gearbox, you will never have difficulty.
