確定油路暢通，柴油機供給系統(tǒng)沒有空氣后，可拆開油泵蓋板，板動操縱手柄，撥動油泵拉桿，看拉桿是否靈活和柱塞彈簧是否斷裂。在自動上料混凝土攪拌機拉桿靈活和柱塞彈簧沒斷的情況下，可啟動柴油機中速運轉(zhuǎn)10分鐘，還有斷火現(xiàn)象時，可用一只銅榔頭輕輕敲擊輸油泵大螺帽，一邊敲一邊聽柴油機聲音，如果聲音不正常，說明輸油泵活塞和推桿發(fā)卡，進行修理或更換。

After confirming that the oil circuit is smooth and there is no air in the diesel engine supply system, remove the cover plate of the oil pump, move the control handle and pull the rod of the oil pump to see whether the rod is flexible and whether the plunger spring is broken. Under the condition that the pull rod of the automatic feeding concrete mixer is flexible and the plunger spring is not broken, the diesel engine can be started to run at medium speed for 10 minutes. If the fire is still broken, a copper hammer can be used to gently tap the big nut of the oil pump, and listen to the sound of the diesel engine while knocking. If the sound is abnormal, it means that the piston and push rod of the oil pump are jammed, and repair or replace them.

拆下噴油器總成，轉(zhuǎn)動曲軸數(shù)圈，即有水噴出，說明缸蓋，缸體有裂紋或砂眼，遇到這種情況時，可向用戶解釋或向自動上料攪拌機公司反映。低壓油流暢通后，可用手壓泵排除油路中的空氣，打開泵頭放氣螺釘，直到?jīng)]有氣泡時，方可上緊放氣螺釘。

Remove the fuel injector assembly and rotate the crankshaft for several turns, that is, water is ejected, indicating that there are cracks or sand holes in the cylinder head and cylinder block. In case of this situation, you can 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 pressure pump, and the pump head vent screw can be opened until there are no bubbles, then the vent screw can be tightened.

油嘴不霧化，油泵柱塞彈簧和彈簧座斷裂，卡死不工作，或是柴油內(nèi)有水。拆下油嘴總成檢查開啟壓力和霧化，如果油嘴總成正常，可讓用戶用干凈柴油裝入壺中用油路旁接法進行試驗。打開自動上料攪拌機油箱開關(guān)，拆下輸油泵進油管，看油流情況，如果油流很快，說明正常，如果油流時斷時續(xù)查油路。

The nozzle does not atomize, the plunger spring and spring seat of the oil pump are broken, stuck and does 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 load clean diesel into the pot and conduct the test by using the oil bypass method. Turn on the oil tank switch of the automatic feeding mixer, remove the oil inlet pipe of the oil pump, and check the oil flow. If the oil flow is fast, it means it is normal. If the oil flow is intermittent, check the oil circuit.

自動上料攪拌機的正確操作方法步驟：

Correct operation steps of automatic feeding mixer:

自動上料攪拌機柔性正確操作方法可以歸納為：一輕、二穩(wěn)、三離、四勤、五協(xié)調(diào)、六嚴(yán)禁。

The flexible and correct operation methods of automatic feeding mixer can be summarized as follows: one light, two stable, three separation, four diligence, five coordination and six prohibition.
             

一輕：在自動上料攪拌機作業(yè)時腳跟緊抵駕駛室地板，腳板和油門踏板保持平行，輕緩地下壓加油踏板。

One light: when the automatic feeding mixer is working, the heel is close to the floor of the cab, the foot board and the accelerator pedal are parallel, and the refueling pedal is gently pressed.

二穩(wěn)：自動上料攪拌機在作業(yè)中，油門始終要穩(wěn)住。一般作業(yè)狀態(tài)下，油門開度在70%左右為宜。

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

三離：在自動上料攪拌機作業(yè)時，腳板應(yīng)和制動踏板分離開，平放到駕駛室地板上，決不能踩在制動踏板上。自動上料攪拌機常常在凹凸不平的工地作業(yè)，如果腳總是踩在制動踏板上，機身上下竄動會造成駕駛員不輕意地踩制動踏板。一般情況下，要用控制油門減速的辦法控制機況和換擋。這樣既避免了頻繁制動造成制動系統(tǒng)過熱，又為自動上料攪拌機快捷的提速帶來方便。

Three separation: during the operation of the automatic feeding mixer, the foot plate should be separated from the brake pedal and placed flat on the floor of the cab. Never step on the brake pedal. Automatic feeding mixer often works on 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 carelessly. Under normal circumstances, to control the throttle deceleration method to control the machine condition and shift. In this way, the overheat of the braking system caused by frequent braking is avoided, and the quick speed increase of the automatic feeding mixer is convenient.

四勤：在自動上料攪拌機作業(yè)時，特別是在鏟挖作業(yè)時，應(yīng)在油門穩(wěn)定情況下，用循環(huán)扳動起升和轉(zhuǎn)斗操縱桿的方法使鏟斗鏟滿物料。起升和轉(zhuǎn)斗操縱杠的循環(huán)扳動就是所說的“勤”。這個過程非常重要，對耗油量的影響很大。

Four frequently: in the operation of automatic feeding mixer, especially in the digging operation, under the condition of stable throttle, the bucket shall be filled with materials by means of cyclic pulling the lifting and rotating bucket control lever. The cyclic pulling of lifting and rotating bucket control lever is called "diligence". This process is very important and has a great impact on fuel consumption.

五協(xié)調(diào)：協(xié)調(diào)就是起升和轉(zhuǎn)斗操縱杠有機的配合。自動上料攪拌機一般的鏟挖過程是將鏟斗平放在地面，平穩(wěn)地駛向料堆。在鏟斗平行鏟往料堆遇阻力時，應(yīng)遵循先起臂后收斗的原則。這樣可以有效地避免鏟斗底部受到阻力，從而能夠充分發(fā)揮出很大的掘起力。

Five coordination: coordination is the organic coordination of lifting and rotary bucket control lever. The general digging process of automatic feeding mixer is to put the bucket flat on the ground and drive to the material pile smoothly. When the bucket is parallel to the material pile and meets resistance, the principle of lifting the arm first and then retracting the bucket should be followed. This can effectively avoid the resistance at the bottom of the bucket, so as to give full play to the great digging force.

六嚴(yán)禁：是嚴(yán)禁輪胎打滑。自動上料攪拌機作業(yè)時，遇阻力而猛加油門往往會出現(xiàn)輪胎打滑的現(xiàn)象。這種現(xiàn)象通常是由于駕駛員操作不當(dāng)造成的，既增加了油耗又損傷了輪胎。其次是嚴(yán)禁后輪翹起。由于自動上料攪拌機的掘起力大，駕駛員通常在鏟挖堅實的原土和石料山等作業(yè)過程中，如果操作不當(dāng)就容易出現(xiàn)兩后輪翹起離地現(xiàn)象。這種翹起動作的落地慣性，會造成鏟斗的刃板斷裂、鏟斗變形；后輪翹起很高時還容易引起前后機架等結(jié)構(gòu)的焊接處開裂，甚板材斷裂等。第三是嚴(yán)禁撞擊料堆。鏟挖普通物料，自動上料攪拌機可以用II檔作業(yè)，嚴(yán)禁以II檔以上的檔位向料堆進行慣性沖擊。正確的方法應(yīng)該是鏟斗在接近料堆時適時地把檔位轉(zhuǎn)換為I檔完成一個鏟料過程。

Six prohibitions: first of all, it is strictly forbidden to skid. During the operation of the automatic feeding mixer, when the resistance is met, the fuel filling door will often have the phenomenon of tire slipping. This phenomenon is usually caused by improper operation of the driver, which not only increases fuel consumption but also damages the tire. Secondly, it is strictly forbidden to turn up the rear wheels. Due to the large digging force of the automatic feeding mixer, the driver is usually in the process of digging solid original soil and stone hill. If the operation is improper, the two rear wheels are prone to lift off the ground. The landing inertia of the lifting action will cause the blade of the bucket to break and the bucket to deform; When the rear wheel is tilted very high, it is easy to cause cracks in the welding joints of the front and rear frames, and even plate fracture. Third, it is strictly forbidden to hit the pile. When shoveling common materials, the automatic feeding mixer can be operated in gear II, and inertial impact to the pile above gear II is strictly prohibited. The correct method should be to change the gear to I gear when the bucket approaches the material pile to complete a shoveling process.
