自動攪拌車操作熄火問題方法

所屬分類：公司新聞發(fā)布時間：2020-09-25 來源：http://m.842233.cn/ 瀏覽量：0

如果我們的自動攪拌車在操作的時候出現(xiàn)熄火的情況，具體應(yīng)該怎么去呢？具體的方法我們在下面自動攪拌車小編給大家詳細的介紹一下。

If our automatic mixer is out of operation, how to solve it? The specific method, we in the following automatic mixer small make up for you a detailed introduction.

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車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, the cover plate of the oil pump can be disassembled, the control handle can be moved, and the pull rod of the oil pump can be pulled 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 truck is flexible and the plunger spring is not broken, the diesel engine can be started to run at a medium speed for 10 minutes. If there is still a fire break phenomenon, a copper hammer can be used to gently tap the big nut of the oil delivery pump, and listen to the noise of the diesel engine at the same time. If the sound is abnormal, it indicates that the piston and push rod of the oil delivery pump are jammed and repaired or replaced.

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車公司反映。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, which means that there are cracks or sand holes in the cylinder head and cylinder block. In this case, 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 pump, and the air release screw at the pump head can be opened until there is no bubble.

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。打開自動上料攪拌車油箱開關(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 oil 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 fill the pot with clean diesel oil and conduct the test with the oil way side connection method. 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, continue to check the oil circuit.

自動攪拌車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)、六嚴禁。

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

一輕：在自動攪拌車作業(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: during the operation of the automatic mixer, the heel of the truck should be close to the floor of the cab, and the foot plate should be parallel to the accelerator pedal, and the fuel pedal should be pressed gently.

二穩(wěn)：自動攪拌車在作業(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。

Second stability: in the operation of the automatic mixer, the throttle should always be stable. Generally, the throttle opening is about 70%.

三離：在自動攪拌車作業(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。自動上料攪拌車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，又為自動上料攪拌車快捷的提速帶來方便。

Three separation: during the operation of the automatic mixer, the foot plate should be separated from the brake pedal and placed flat on the cab floor, and never step on the brake pedal. The automatic loading 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. In general, we should control the engine condition and shift gear by controlling the throttle deceleration. This not only avoids the overheat of the braking system caused by frequent braking, but also brings convenience for the rapid speed-up of the automatic feeding mixer.

四勤：在自動攪拌車作業(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 mixer truck, especially in shoveling operation, the bucket shall be filled with materials by pulling the lifting and rotating control lever in a cycle under the condition that the throttle is stable. The cyclic pulling of lifting and bucket turning control levers 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。自動攪拌車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)揮的掘起力。

Five coordination: coordination is the organic coordination of lifting and bucket control lever. The general digging process of automatic mixer truck is to place the bucket on the ground and drive to the pile smoothly. When the bucket is parallel shoveling to the material pile, the principle of lifting the arm first and then collecting 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 maximum digging force.

六嚴禁：是嚴禁輪胎打滑。自動攪拌車作業(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。其次是嚴禁后輪翹起。由于自動上料攪拌車的掘起力大，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。

Six prohibitions: first of all, it is strictly forbidden to skid the tires. When an automatic mixer truck is working, when it encounters resistance and is fierce, the phenomenon of tire skidding often occurs at the fuel door. This phenomenon is usually caused by improper operation of the driver, which increases fuel consumption and damages the tire. Secondly, the rear wheels are strictly prohibited from warping. Due to the large digging force of the automatic loading mixer, the driver usually digs the solid original soil and stone hill, if the operation is not correct, the two rear wheels will be prone to rise and leave the ground.

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。第三是嚴禁撞擊料堆。鏟挖普通物料，自動攪拌車可以用II檔作業(yè)，嚴禁以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。

The landing inertia of this kind of lifting action will cause the blade of the bucket to fracture and the bucket to deform; when the rear wheel is very high, it is easy to cause the welding joint cracking of the front and rear frame, and even the plate fracture. Third, it is forbidden to hit the pile. When excavating common materials, the automatic mixer can operate in gear II. It is strictly forbidden to make inertial impact to the material pile at the gear position above II. The correct method should be that when the bucket is close to the pile, it should timely change the gear to I gear to complete a shoveling process.、
