After the fixed oil circuit is smooth and there is no air in the diesel engine supply system, the cover plate of the oil pump can be removed, the control handle can be pressed, and the pull rod of the oil pump can be moved to see whether the pull rod is flexible and whether the plunger spring is broken. Under the condition that the pull rod of the automatic loading concrete mixer is flexible and the plunger spring is not broken, the diesel engine can be started to run at a medium speed for 10 minutes. In case of fire break, a copper hammer can be used to tap the large nut of the oil pump gently while listening to the sound of the diesel engine. If the sound is not normal, it means that the piston and the pushrod of the oil pump are jammed and repaired or replaced.

拆下喷油器总成，转动曲轴数圈，即有水喷出，说明缸盖，缸体有裂纹或砂眼，遇到这种情况时，可向用户解释或向自动上料混凝土搅拌车公司反映。低压油流畅通后，可用手压泵排除油路中的空气，打开泵头放气螺钉，直到没有气泡时，方可上紧放气螺钉。

Remove the fuel injector assembly and rotate the crankshaft for several turns, i.e. there is water ejecting, indicating that there is crack or sand hole in the cylinder head and cylinder block. In this case, explain to the user or report to the automatic feeding mixer company. After the low-pressure oil flow is smooth, the air in the oil circuit can be removed by hand pump, and the air bleed screw of the pump head can be opened until there is no bubble, then the air bleed screw can be tightened.

油嘴不雾化，油泵柱塞弹簧和弹簧座断裂，卡死不工作，或是柴油内有水。拆下油嘴总成检查开启压力和雾化，如果油嘴总成正常，可让用户用干净柴油装入壶中用油路旁接法进行试验。打开自动上料混凝土搅拌车油箱开关，拆下输油泵进油管，看油流情况，如果油流很快，说明正常，如果油流时断时续查油路。

The nozzle is not atomized, the plunger spring and spring seat of the oil pump are broken, stuck and do not work, or there is water in the diesel oil. Remove the nozzle assembly to check the opening pressure and atomization. If the nozzle assembly is normal, the user can use clean diesel oil to fill the pot and use the side connection method of the oil circuit to conduct the test. Turn on the oil tank switch of the automatic feeding mixer, remove the oil inlet pipe of the oil delivery pump, and check the oil flow. If the oil flow is fast, it indicates that it is normal. If the oil flow is intermittent, check the oil circuit continuously.

自动上料混凝土搅拌车的正确操作方法步骤

Correct operation procedure of automatic loading mixer

自动上料混凝土搅拌车柔性正确操作方法可以归纳为：一轻、二稳、三离、四勤、五协调、六严禁。

The flexible and correct operation methods of the automatic feeding mixer can be summarized as follows: one light, two stable, three departures, four attendance, five coordination and six prohibitions.

一轻：在自动上料混凝土搅拌车作业时脚跟紧抵驾驶室地板，脚板和油门踏板保持平行，轻缓地下压加油踏板。

First light: during the operation of the automatic loading mixer, keep the heel close to the floor of the cab, keep the foot plate parallel to the accelerator pedal, and press the oil pedal gently.

二稳：自动上料混凝土搅拌车在作业中，油门始终要稳住。一般作业状态下，油门开度在70%左右为宜。

Two stable: in the operation of the automatic feeding mixer, the accelerator should always be stable. In general operation, the throttle opening is about 70%.

三离：在自动上料混凝土搅拌车作业时，脚板应和制动踏板分离开，平放到驾驶室地板上，决不能踩在制动踏板上。自动上料混凝土搅拌车常常在凹凸不平的工地作业，如果脚总是踩在制动踏板上，机身上下窜动会造成驾驶员不轻意地踩制动踏板。一般情况下，要用控制油门减速的办法控制机况和换挡。这样既避免了频繁制动造成制动系统过热，又为自动上料混凝土搅拌车快捷的提速带来方便。

Three off: during the operation of the automatic feeding mixer, the foot plate shall be separated from the brake pedal and placed on the floor of the cab, never on the brake pedal. The automatic loading mixer often works in the uneven construction site. If the foot is always on the brake pedal, the body will move up and down, which will cause the driver to step on the brake pedal unwittingly. In general, it is necessary to control the engine condition and shift by controlling the throttle deceleration. This not only avoids the brake system overheating caused by frequent braking, but also brings convenience for the rapid speed-up of the automatic feeding mixer.

四勤：在自动上料混凝土搅拌车作业时，特别是在铲挖作业时，应在油门稳定情况下，用循环扳动起升和转斗操纵杆的方法使铲斗铲满物料。起升和转斗操纵杠的循环扳动就是所说的“勤”。这个过程非常重要，对耗油量的影响很大。

Siqin: during the operation of the automatic loading mixer, especially in the digging operation, the bucket shall be full of materials by turning the lifting and turning control levers circularly when the accelerator is stable. Lift and turn the bucket control lever cycle pull is called "frequently.". This process is very important and has a great impact on fuel consumption.

五协调：协调就是起升和转斗操纵杠有机的配合。自动上料混凝土搅拌车一般的铲挖过程是将铲斗平放在地面，平稳地驶向料堆。在铲斗平行铲往料堆遇阻力时，应遵循先起臂后收斗的原则。这样可以有效地避免铲斗底部受到阻力，从而能够充分发挥的掘起力。

5. Coordination: coordination is the organic coordination of lifting and rotating bucket control bars. In the general digging process of the automatic loading mixer, the bucket is first placed on the ground, and it drives smoothly to the pile. When the parallel shovel of the bucket encounters resistance to the material pile, the principle of first lifting the arm and then retracting the bucket shall be followed. In this way, the resistance on the bottom of the bucket can be effectively avoided, so as to give full play to the maximum digging force.

六严禁：是严禁轮胎打滑。自动上料混凝土搅拌车作业时，遇阻力而猛加油门往往会出现轮胎打滑的现象。这种现象通常是由于驾驶员操作不当造成的，既增加了油耗又损伤了轮胎。其次是严禁后轮翘起。由于自动上料混凝土搅拌车的掘起力大，驾驶员通常在铲挖坚实的原土和石料山等作业过程中，如果操作不当就容易出现两后轮翘起离地现象。这种翘起动作的落地惯性，会造成铲斗的刃板断裂、铲斗变形；后轮翘起很高时还容易引起前后机架等结构的焊接处开裂，甚板材断裂等。第三是严禁撞击料堆。铲挖普通物料，自动上料混凝土搅拌车可以用II档作业，严禁以II档以上的档位向料堆进行惯性冲击。正确的方法应该是铲斗在接近料堆时适时地把档位转换为I档完成一个铲料过程。

6. No: first, no tire slipping. During the operation of the automatic loading mixer, when encountering the resistance and the sudden filling valve, the tire often slips. This phenomenon is usually caused by improper operation of the driver, which increases fuel consumption and damages the tire. Second, it is strictly prohibited to raise the rear wheel. Due to the large digging force of the automatic loading mixer, the driver usually digs the solid raw soil and stone mountain during the operation process, if the operation is improper, the two rear wheels are prone to rise and leave the ground. The landing inertia of this kind of lifting action will cause the edge plate of the bucket to break and the bucket to deform; when the rear wheel is very high, it is easy to cause the welding joints of the front and rear frames and even the plate to break. Third, it is strictly prohibited to impact the pile. Shovel and excavate common materials. The automatic loading mixer can operate in gear II. It is strictly prohibited to use gear II or above to carry out inertial impact on the pile. The correct way is to shift the bucket from gear I to gear I in time when the bucket is close to the pile to complete a shoveling process.
